Answer:
A. Pr(8) = 1/10
B. Pr(odd) = 1/2
C. Pr(even) = 1/2
D. Pr(less than 6) = 1/2
E. Pr(prime) = 2/5
F. Pr(3 or 8) = 1 / 5
G. Pr(8, 9 or 10) = 3/10
H. Pr(greater than 9) = P(10) = 1/10
Step-by-step explanation:
We assume a FAIR 10-faced die, meaning there is an equal probability of throwing any one of the ten numbers.
With 10 possible outcomes each with equal probability, the probability of throwing any number is 1/10.
(It is preferable to work with fractions in probability because fractions are exact numbers, while decimals can often be rounded, or truncated).
A. Pr(8) means probability of throwing an 8, therefore Pr(8) = 1/10
B. Pr(odd) there are 5 odd number from 1 to 10, so Pr(odd) = 5/10 = 1/2
C. Pr(even) there are 5 even number from 1 to 10, so Pr(even) = 5/10 = 1/2
D. Pr(less than 6) there are 5 numbers less than 6 (between1 to 10),
so Pr(less than 6) = 5/10 = 1/2
E. Pr(prime) (remember that 1 is not prime)
A prime number is an integer not divisible by any number except one and itself.
Between 1 to 10, the four prime numbers are 2,3,5,7
therefore Pr(prime) = 4/10 = 2/5
F. Pr(3 or 8)
(3 or 8) make 2 successful outcomes out of 10, so Pr(3 or 8) = 2/10 = 1 / 5
G. Pr(8, 9 or 10)
similarly, (8,9 or 10) make three successful possible outcomes out of 10, so
P(8,9 or 10) = 3/10
H. Pr(greater than 9)
there is only one successful outcome, namely "10" out of 10 possible outcomes. So
P(greater than 9) = P(10) = 1/10
1. please explain what’s a “die” all I know was “dice” but dice is 6 sided yea?
A die is singular for dice, which can take up any number of faces. With a 10-faced solid, we can make a 10-faced die numbered 1 to 10.
2. and please explain the answer... I’m international student so I still need some explanation for the questions and answers thank you
See solutions above.
Answer:
Remember that standard probabilities are defined as the ratio between the number of favorable cases, and the total number of possible events.
In this case, we have a 10-sided die, which means its faces are numbered from 1 to 10, which gives us 10 total number of possible events. In other words, the denominator of the ratio is going to be 10.
Now we're able to find each probability.
(A) Probability of getting an 8:\(P_{8} =\frac{1}{10}=0.10\)
The numerator is 1 because there's only one number 8 in the die, that means the number of favorable cases is 1, and, as we said before, the total number of possible events is 10.
(B) Probability of getting an odd number:\(P_{odd} =\frac{5}{10}=0.5\)
The numerator is 5 because there are 5 odd numbers from 1 to 10. In other words, there are 5 favorable cases to this probability.
(C) Probability of getting an even number:\(P_{even}=\frac{5}{10}=0.5\)
There are 5 even numbers from 1 to 10, that's why we had the same probability.
(D) Probability of getting a number less than 6:We know that there are only 5 numbers less than 6 for this die.
\(P_{<6}=\frac{5}{10}=0.5\)
(E) Probability of getting a prime number:A prime number is such that it can be divided only by itself and the unit. So, there are four prime numbers from 1 to 10, which are 2, 3, 5, 7.
\(P_{prime}=\frac{4}{10}=0.4\)
(F) Probability of getting 3 or 8:When we are going to find the probability of an event "or" another, we must sum those favorable cases.
\(P_{3 \ or \ 8} =\frac{1+1}{10}=\frac{2}{10}=0.2\)
(G) Probability of getting 8, 9, or 10:In this case, we need to some all three favorable cases. The die has only one 8, one 9 and one 10. So, the probability is
\(P_{8,9,10}=\frac{1+1+1}{10}=\frac{3}{10} =0.3\)
(H) Probability of getting a number greater than 9:We know that there's only one number greater than 10 on such die.
\(P_{>10}=\frac{1}{10}=0.1\)
Lastly, "die" refers to this special 10-sided dice. In other problems, you can find "a die" with more faces even. But, in general, "die" refers to a dice.

Answers
The equation 4x + 3y = -18 is parallel to the given line since they have the same slope.
Equation of a lineThe equation of a line in slope-intercept form is expressed as y = mx + b
where
m is the slope
b is the y-intercept
Given the equation below
y =-4/3x-7
The slope of the line is -4/3.
In order to determine the equation that represents a line which is parallel to the line, we need to determine the line that has a slope of -4/3
For the equation 4x + 3y = -18:
3y = -4x - 18
Divide through by 3 to have:
3y/3 = -4x/3 - 18/3
y = -4/3 x - 6
Since the slope of the line is -4/3, hence the equation 4x + 3y = -18 is parallel to the given line.

Answers
With a 95% confidence interval, the proportion of all shrubs of this species that will resprout after a fire is between 0.17 and 0.67.
What is a confidence interval?
An area surrounding a measurement that indicates how accurate it is called a confidence interval.
Here, we have
Confidence interval is written as
Sample proportion ± margin of error
Margin of error = z × √pq/n
Where
z represents the z score corresponding to the confidence level
p = sample proportion. It also means the probability of success
q = probability of failure
q = 1 - p
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 14
x = 6
p = 6/14 = 0.42
q = 1 - 0.42 = 0.58
To determine the z score, we subtract the confidence level from 100% to get α
α = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
This is the area in each tail.
Since we want the area in the middle, it becomes
1 - 0.025 = 0.975
The z score corresponding to the area on the z table is 2.05. Thus, Thus, the z score for a confidence level of 95% is 1.96
Therefore, the 95% confidence interval is
0.42 ± 1.96√(0.58)(0.42)/14
The lower limit of the confidence interval is
0.42 - 0.25 = 0.17
The upper limit of the confidence interval is
0.42 + 0.25 = 0.67
Hence, with a 95% confidence interval, the proportion of all shrubs of this species that will resprout after a fire is between 0.17 and 0.67.

One sheet of aluminum is 0.229 incg thick. How thick is a stack of 31 sheets if aluminum?
Answers
The stack of 31 sheets of aluminum will be approximately 7.099 inches thick.
- One sheet of aluminum is 0.229 inches thick.
- To find the thickness of a stack of sheets, we need to multiply the thickness of one sheet by the number of sheets.
- So, to find the thickness of 31 sheets of aluminum, we need to multiply 0.229 inches by 31.
- 0.229 x 31 = 7.099 inches.
- Therefore, the stack of 31 sheets of aluminum will be approximately 7.099 inches thick.
To determine the thickness of a stack of 31 sheets of aluminum, we need to consider the thickness of one sheet and then multiply it by the number of sheets in the stack.
Firstly, we are given that one sheet of aluminum is 0.229 inches thick. This means that if we were to measure the thickness of one sheet using a ruler or calipers, we would get a reading of 0.229 inches.
Next, we need to find the thickness of 31 sheets of aluminum. To do this, we need to multiply the thickness of one sheet by the number of sheets. This can be expressed as:
Thickness of stack = Thickness of one sheet x Number of sheets
Substituting the values we have:
Thickness of stack = 0.229 x 31
Multiplying these two values gives us:
Thickness of stack = 7.099 inches
Therefore, the stack of 31 sheets of aluminum will be approximately 7.099 inches thick.
In conclusion, we can determine the thickness of a stack of sheets by multiplying the thickness of one sheet by the number of sheets. In this case, we were given the thickness of one sheet of aluminum and the number of sheets in the stack, which allowed us to calculate the thickness of the entire stack.

the daily revenue at a university snack bar has been recorded for the past five years. records indicate that the mean daily revenue is $2500 and the standard deviation is $300. suppose that 100 days are randomly selected. what is the probability that the average daily revenue of the sample is between $2450 and $2460?
Answers
Therefore, the probability that the average daily revenue of the sample is between $2450 and $2460 is approximately 0.0443 or 4.43%.
The distribution of the sample means of size n = 100 from a population with mean μ = $2500 and standard deviation σ = $300 can be approximated by a normal distribution with mean = μ = $2500 and standard deviation = σ/√n = $300/√100 = $30.
Thus, we need to find the probability that the sample mean falls between $2450 and $2460.
Z-score for $2450:
z = (2450 - 2500) / 30 = -1.67
Z-score for $2460:
z = (2460 - 2500) / 30 = -1.33
Using a standard normal distribution table or calculator, we can find the probabilities associated with these z-scores:
P(z < -1.67) = 0.0475
P(z < -1.33) = 0.0918
Therefore, the probability that the average daily revenue of the sample is between $2450 and $2460 is:
P(-1.67 < z < -1.33) = P(z < -1.33) - P(z < -1.67)
= 0.0918 - 0.0475
= 0.0443
So, the probability is approximately 0.0443 or 4.43%.

Step-by-step explanation:
You want to calculate the interest on $1500 at 4.5% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
I = P x r x t
Where:
P is the principal amount, $1500.00.
r is the interest rate, 4.5% per year, or in decimal form, 4.5/100=0.045.
t is the time involved, 5....year(s) time periods.

For the first problem, the cost for the neighbor to put landscape timbers around their garden would be $120, and the cost to mulch their garden would be $180. For the second problem, it would cost $39 to print a border around a poster with dimensions three times larger and $30 to print a poster with dimensions three times larger (no border).
1a. The dimensions of the neighbor's garden are 20ft by 30ft (doubled dimensions of your garden). The perimeter of the garden is 100ft. Since you spent $30 on landscape timbers around your garden, the cost of the neighbor's garden would be $30 * 2 = $60.
1b. The area of the neighbor's garden is 20ft x 30ft = 600 sq ft. Since you spent $45 to cover your garden with mulch, the cost of the neighbor's garden would be $45 * 4 = $180.
2a. The dimensions of the poster are multiplied by three, so the new dimensions are 9ft by 15ft. The perimeter of the poster is 48ft. The cost of printing the border would be $3 * 16 = $48. The total cost of printing the poster with the border would be $10 + $48 = $58.
2b. The area of the new poster is 27 times the area of the original poster. Since it costs $10 to print the original poster, the cost of printing the new poster would be $10 * 27 = $270.

The subscription rates in the United States and Canada for a civil engineering magazine are 1 year, $7.50;2 years, $12.00;3 years, $16.00; and 5 years, $22.00. Compute the rate of return on the investment for purchasers of: a) 2-year subscriptions b) 3-year subscriptions c) 5-year subscriptions.
Answers
a) 2-year subscriptions is approximately 20%.
b) 3-year subscriptions is approximately 29.56%.
c) 5-year subscriptions is approximately 41.33%.
To compute the rate of return on the investment for purchasers of different subscription lengths, we need to calculate the average annual cost of each subscription option.
a) 2-year subscriptions:
The cost of a 2-year subscription is $12.00. To find the average annual cost, we divide the total cost by the number of years:
Average annual cost = $12.00 / 2 = $6.00
b) 3-year subscriptions:
The cost of a 3-year subscription is $16.00. To find the average annual cost, we divide the total cost by the number of years:
Average annual cost = $16.00 / 3 = $5.33 (rounded to two decimal places)
c) 5-year subscriptions:
The cost of a 5-year subscription is $22.00. To find the average annual cost, we divide the total cost by the number of years:
Average annual cost = $22.00 / 5 = $4.40
Now, to calculate the rate of return on the investment, we need to compare the average annual cost to the regular 1-year subscription rate of $7.50.
a) For 2-year subscriptions:
Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%
Rate of return = (1 - $6.00 / $7.50) * 100% ≈ 20%
b) For 3-year subscriptions:
Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%
Rate of return = (1 - $5.33 / $7.50) * 100% ≈ 29.56%
c) For 5-year subscriptions:
Rate of return = (1 - Average annual cost / 1-year subscription rate) * 100%
Rate of return = (1 - $4.40 / $7.50) * 100% ≈ 41.33%
Therefore, the rate of return on the investment for purchasers of:
a) 2-year subscriptions is approximately 20%.
b) 3-year subscriptions is approximately 29.56%.
c) 5-year subscriptions is approximately 41.33%.

please PLEASE help me!!! Write an expression that can be used to produce vector r from vectors p and q. Explain how you determined that expression
Answers
Answer:
r = p - q
Step-by-step explanation:
Write the two given vectors using i and j components.
i = unit vector in x direction
j = unit vector in y direction
p = -i - 3j
q = 3i - 4j
Now how can you combine these two vectors and get r when
r = -4i + j?
Adding p and q gives this:
p + q = -i - 3j + 3i - 4j = 2i - 7j
That is not r, so the addition of the vectors p and q does not work.
How about subtraction?
Start with -i from p and subtract 3i from q. You do get -4i which is the x-component of r.
Then start with -3j from p and subtract -4j from q. You get -3j - (-4j) = -3j + 4j = j which is the y-component of r.
That subtraction works.
p - q = -i - 3j - (3i - 4j) = -i - 3j - 3i + 4j = -4i + j which is exactly what r is.
Answer: r = p - q
