A woman deposits $300 in a savings account that pays 6% annually. If she withdraws all the money in the account after 120 days, how much does she withdraw (rounded to the nearest dollar)?
Answers
The woman will withdraw $300 given 6% interest rate annually.
We can use the formula for simple interest to solve this problem:
I = Prt
where I is the interest earned, P is the principal (initial deposit), r is the annual interest rate as a decimal, and t is the time in years. Since the interest rate is given as an annual rate, we need to convert it to a daily rate by dividing by 365:
r = 0.06/365 = 0.00016438356
The time in years is 120/365 = 0.3287671233 years. Now we can plug in the values and solve for I:
I = 300 * 0.00016438356 * 0.3287671233 = 0.01699999999
The interest earned is $0.017, which is negligible. Therefore, the woman will withdraw the entire principal plus any interest earned, which is:
300 + 0.017 = $300.02
Rounding to the nearest dollar, the woman will withdraw $300.

Suppose a baker claims that the average bread height is more than 15cm. Several of this customers do not believe him. To persuade his customers that he is right, the baker decides to do a hypothesis test. He bakes 10 loaves of bread. The mean height of the sample loaves is 17 cm with a sample standard deviation of 1.9 cm. The heights of all bread loaves are assumed to be normally distributed. The baker is now interested in obtaining a 95% confidence interval for the true mean height of his loaves. What is the lower bound to this confidence interval? 2 cm (round to 2 decimal places) What is the upper bound to this confidence interval? cm (round to 2 decimal places) For the following situations, use RStudio to find the appropriate t-critical values that would be needed to construct a confidence interval. Round all critical values to the second decimal place. 1. n = 15, confidence level is 95%, x= 35 and s = 2.7, t-critical value- 2, n = 37, confidence level is 99%, x= 82 and s = 5.9 t-critical value- 2 3, n 1009, confidence level is 90%, x 0.9 and s-0.04 t- critical value = 2 2
Answers
The correct answer is Confidence interval lower bound: 32.52 cm,Confidence interval upper bound: 37.48 cm
To calculate the confidence interval for the true mean height of the loaves, we can use the t-distribution. Given that the sample size is small (n = 10) and the population standard deviation is unknown, the t-distribution is appropriate for constructing the confidence interval.
The formula for a confidence interval for the population mean (μ) is:
Confidence Interval = sample mean ± (t-critical value) * (sample standard deviation / sqrt(sample size))
For the first situation:
n = 15
Confidence level is 95% (which corresponds to an alpha level of 0.05)
x = 35 (sample mean)
s = 2.7 (sample standard deviation)
Using RStudio or a t-table, we can find the t-critical value. The degrees of freedom for this scenario is (n - 1) = (15 - 1) = 14.
The t-critical value at a 95% confidence level with 14 degrees of freedom is approximately 2.145.
Plugging the values into the formula:
Confidence Interval = 35 ± (2.145) * (2.7 / sqrt(15))
Calculating the confidence interval:
Lower Bound = 35 - (2.145) * (2.7 / sqrt(15)) ≈ 32.52 (rounded to 2 decimal places)
Upper Bound = 35 + (2.145) * (2.7 / sqrt(15)) ≈ 37.48 (rounded to 2 decimal places)
Therefore, the lower bound of the confidence interval is approximately 32.52 cm, and the upper bound is approximately 37.48 cm.
For the second situation:
n = 37
Confidence level is 99% (which corresponds to an alpha level of 0.01)
x = 82 (sample mean)
s = 5.9 (sample standard deviation)
The degrees of freedom for this scenario is (n - 1) = (37 - 1) = 36.
The t-critical value at a 99% confidence level with 36 degrees of freedom is approximately 2.711.
Plugging the values into the formula:
Confidence Interval = 82 ± (2.711) * (5.9 / sqrt(37))
Calculating the confidence interval:
Lower Bound = 82 - (2.711) * (5.9 / sqrt(37)) ≈ 78.20 (rounded to 2 decimal places)
Upper Bound = 82 + (2.711) * (5.9 / sqrt(37)) ≈ 85.80 (rounded to 2 decimal places)
Therefore, the lower bound of the confidence interval is approximately 78.20 cm, and the upper bound is approximately 85.80 cm.
For the third situation:
n = 1009
Confidence level is 90% (which corresponds to an alpha level of 0.10)
x = 0.9 (sample mean)
s = 0.04 (sample standard deviation)
The degrees of freedom for this scenario is (n - 1) = (1009 - 1) = 1008.
The t-critical value at a 90% confidence level with 1008 degrees of freedom is approximately 1.645.
Plugging the values into the formula:
Confidence Interval = 0.9 ± (1.645) * (0.04 / sqrt(1009))

A total of 3 ft falls over 3 days. On the first day, 1/6 of the total rain falls. On the second day, 7/12 of the total rain falls. How much rain falls each day in inches? Show your work. Please help.
Answers
Answer:
Day 1: 6 inches
Day 2: 21 inches
Day 3: 9 inches
Step-by-step explanation:
First, we need to convert the total rainfall from feet to inches. Since 1 foot is equal to 12 inches, 3 feet is equal to 36 inches.
On the first day, 1/6 of the total rainfall falls, so:
(1/6) * 36 = 6 inches
On the second day, 7/12 of the total rainfall falls, so:
(7/12) * 36 = 21 inches
To find the rainfall on the third day, we can subtract the rainfall on the first and second days from the total rainfall:
36 - 6 - 21 = 9 inches
Therefore, the amount of rainfall on each day, in inches, is:
Day 1: 6 inches
Day 2: 21 inches
Day 3: 9 inches

Answers
Answer:
a) 0.5447
b) 0.0228
c) 0.4325
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normal distribution with a mean of 9.6 minutes and a standard deviation of 2.3 minutes.
This means that \(\mu = 9.6, \sigma = 2.3\)
a. between 5 and 10 min
This is the p-value of Z when X = 10 subtracted by the p-value of Z when X = 5. So
X = 10
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{10 - 9.6}{2.3}\)
\(Z = 0.17\)
\(Z = 0.17\) has a p-value of 0.5675
X = 5
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{5 - 9.6}{2.3}\)
\(Z = -2\)
\(Z = -2\) has a p-value of 0.0228
0.5675 - 0.0228 = 0.5447 probability that a randomly received emergency call is between 5 and 10 minutes.
b. less than 5 min
p-value of Z when X = 5, which from item a), is 0.0228, so 0.0228 probability that a randomly received emergency call is of less than 5 minutes.
c. more than 10 min
1 subtracted by the p-value of Z when X = 10, which, from item a), is of 0.5675.
1 - 0.5675 = 0.4325
0.4325 probability that a randomly received emergency call is of more than 10 minutes.

Joshua is going to invest $1,000 and leave it in an account for 18 years. Assuming the interest is compounded monthly, what interest rate, to the nearest hundredth of a percent, would be required in order for Joshua to end up with $1,500 ?
Answers
The rate is of interest such that the initial investment of $1,000 becomes $1,500 in 18 years will be 2.25%.
What is compound interest?Compound interest is applicable when there will be a change in principal amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
As per the given,
Principle amount P = $1,000
Time period T = 18 years
Interest rate = R %
Number of times interest applied per time period n = 12
Total investment = P[1 + R/n]^(nT)
1500 = 1000[1 + R/12]^(12 x 18)
1.5= (1 + R/12)²¹⁶
1.001878916 = 1 + R/12
R = 0.02256 = 2.25%
Hence "The rate is of interest such that the initial investment of $1,000 becomes $1,500 in 18 years will be 2.25%".

Step-by-step explanation:
A high school is running a campaign against the over-use of technology in teens. The committee running the campaign decides to look at the difference in social media usage between teens and adults. and then Find a 90% confidence interval for the difference in proportions.
The formula for confidence interval for the difference between the proportions is given as:
p1 - p2 ± z × √p1 (1 - p1)/n1 + p2(1 - p2)/n2
From the question
We have two groups.
Group 1
They take a random sample of 200 teens in their city (Group 1) and find that 85% of them use social media,
p1 = x/n1
n1 = 200
x1 = 85% × 200 = 170
p1 = 170/200
p1 = 0.85
Group 2
Take another random sample of 180 adults in their city (Group 2) and find that 55% of them use social media.
p2 = x/n1
n2= 180
x2 = 55% × 180 = 99
p2 = 99/180
p2 = 0.55
z = z score for 90% Confidence Interval = 1.645
p1 - p2 ± z × √p1 (1 - p1)/n1 + p2(1 - p2)/n2
= 0.85 - 0.55 ± 1.645 √0.85(1 - 0.85)/200 + 0.55(1 - 0.55)/180
= 0.85 - 0.55 ± 1.645 √0.85(0.15)/200 + 0.55(0.45)/180
= 0.30 ± 1.645 × √0.0020125
= 0.30 ± 1.645 × 0.0448608961
= 0.30 ± 0.0737961741
Hence
= 0.30 - 0.0737961741
= 0.2262038259
= 0.30 + 0.0737961741
= 0.3737961741
Therefore, 90% confidence interval for the difference in proportions is (0.226, 0.374
A bank offers two checking account plans. Plan A has a base service charge of $9.00 per month plus 7 cents per check. Plan B charges a base service charge for $1.00 per month plus 27 cents per check. For what number of checks per month will plan A be better than plan B?How would I write that in interval notation?
Answers
Answer:
• The number of checks, c is greater than 40.
,• (40, ∞)
Explanation:
Let the number of checks per month = c
Plan A
• Base service charge = $9.00 per month.
,• Charge per check =7 cents = $0.07
The total cost for plan A is: 9+0.07c
Plan B
• Base service charge = $1.00 per month.
,• Charge per check =27 cents = $0.27
The total cost for plan B is: 1+0.27c
For plan A to be better than plan B, the total cost for plan A must be less than the total cost for plan B. That is:
\(9+0.07c<1+0.27c\)The inequality is solved for c.
\(\begin{gathered} 9-1<0.27c-0.07c \\ 8<0.2c \\ \text{Divide both sides by 0.2} \\ \frac{8}{0.2}<\frac{0.2c}{0.2} \\ 4040 \end{gathered}\)Plan A will be better than Plan B whenever the number of checks is greater than 40.
This can be written in the interval notation as:

Lily pads increase by 25% every 10 days.lf a pond starts with 22 lily pads,how many will there be after 50 days?
Answers
We conclude that after 50 days, there will be 67 lily pads.
how many will there be after 50 days?
We know that the number increases by 25% every 10 days.
In 50 days we have 5 groups of 10 days, so there will be five increases of 25%.
We know that the initial number is 22 lily pads, if we apply five consecutive increases of the 25% we get:
N = 22*(1 + 25%/100)*...*(1 + 25%/100%)
( the factor (1 + 25%/100%) appears five times)
So we can rewrite:
N = 22*(1 + 25%/100%)⁵
N = 22*(1 + 0.25)⁵ = 67.1
Which can be rounded to the nearest whole number, which is 67.
So we conclude that after 50 days, there will be 67 lily pads.

Answers
1. Using a system of equations, the number of adults who paid was 101.
2. Using a system of equations, the number of seniors who paid was 229.
What is a system of equations?A system of equations involves the use of more than one equation to solve an equation problem simultaneously.
A system of equations is also known as simultaneous equations.
Charge per adult = $6
Charge per senior = $3
The total receipts = $1,293
The number of movie-goers who paid = 330
Let adults = x
Let seniors = y
6x + 3y = 1,293 ... Equation 1
x + y = 330 ... Equation 2
x = 330 - y ... Equation 3
In Equation 1:
6(330 - y) + 3y = 1,293
1,980 - 6y + 3y = 1,293
-6y + 3y = 1,293 - 1,980
-3y = -687
y = 229

x = 330 - 229
x = 101
Check:
In Equation 1:
6x + 3y = 1,293
6(101) + 3(229) = 1,293

Answers
The probability of a negative return if the returns are normally distributed, we can use the mean and standard deviation of the returns and If the distribution is symmetrical but otherwise unknown, it may be more difficult to estimate the probability of a negative return without more information about the shape of the distribution.
To determine how confident we can be that the mean of the given data sample is greater than 40, we would need to perform a statistical test such as a t-test or a z-test to compare the sample mean to the value of 40.
We would need to know the sample size, standard deviation, and any other relevant information about the data to calculate the appropriate test statistic and determine the p-value, which would tell us the probability of observing a sample mean as extreme as the one we obtained if the true population mean was actually 40.
To determine how confident we should be that the portfolio manager will continue to produce positive returns, we would need to analyze the distribution of returns and determine whether it is skewed or symmetrical and whether it follows a normal distribution or a different distribution. If the distribution is skewed or non-normal, it may be more difficult to estimate the probability of positive returns. However, if the distribution is symmetrical and follows a normal distribution, we can use the mean and standard deviation of the returns to calculate the probability of a positive return using the normal distribution.
If the returns of the investment strategy are normally distributed, we can use the mean and standard deviation of the returns to calculate the probability of a negative return using the normal distribution. If the distribution is symmetrical but otherwise unknown, it may be more difficult to estimate the probability of a negative return without more information about the shape of the distribution.

Solve 2^x-2=8^4 but not solving for x
Answers
Without explicitly solving for x, we can conclude that the solution to the equation 2^x - 2 = 8^4 is x = 12.
To solve the equation 2^x - 2 = 8^4 without explicitly solving for x, we can simplify the equation using exponent rules and observe the relationship between the numbers.
First, let's simplify the equation:
2^x - 2 = 8^4
We know that 8 can be expressed as 2^3, so we can rewrite the equation as:
2^x - 2 = (2^3)^4
Applying the exponent rule (a^m)^n = a^(mn), we can simplify further:
2^x - 2 = 2^(34)
Simplifying the right side of the equation:
2^x - 2 = 2^12
Now, we can observe that both sides of the equation have the same base, which is 2. In order for the equation to hold true, the exponents must be equal:
x = 12
Therefore, we may deduce that the answer to the equation 2x - 2 = 84 is x = 12 without having to explicitly solve for x.

A decorative vase is on sale from $80 to $50. What is the
percent change of the price of the vase. Be sure to indicate
if it was a decrease or increase. Show the formula you use to
solve. Round to a whole number.
Answers
Since the result is negative, we can say that the price of the vase decreased by 37.5%. Rounding to a whole number, the percent change is 38% (since a 37.5% decrease is approximately equal to a 38% decrease).
What is percent?Percent (often symbolized as "%") is a way of expressing a fraction or a portion of something in terms of hundredths. It is used to describe the relationship between a part and a whole, with the whole being represented by 100%. Percentages are commonly used in many areas of life, such as finance, business, and statistics. They can be used to describe changes in values over time, to compare different quantities or amounts, or to express probabilities or frequencies.
Here,
The percent change in the price of the vase can be calculated using the formula:
percent change = (new price - old price) / old price x 100%
In this case, the old price of the vase was $80 and the new price is $50. Substituting these values into the formula, we get:
percent change = ($50 - $80) / $80 x 100%
percent change = -0.375 x 100%
percent change = -37.5%

Place √31 in the appropriate place on the number line. Round to tenths
Answers
Answer: To place √31 on the number line, we first need to find its approximate value.
√31 is between 5 and 6 since 5²=25 and 6²=36. To find a more precise value, we can use a calculator or estimate using long division.
Using a calculator, we get:
√31 ≈ 5.56776436
Rounding to tenths, we get:
√31 ≈ 5.6
To place 5.6 on the number line, we can mark the point between 5.5 and 5.7.
