The time taken to complete 5 questions is (option b) 22 minutes, 30 seconds

Given,

The number of questions = 2

Time taken to complete 2 questions = 9 minutes

Now,

The number of questions = 5

We have to find the time taken to complete 5 questions:

We can consider ratio here:

That is,

Number of questions : Time taken to complete

So,

2 : 9 and 5 : x

Lets equate:

2 : 9 = 5 : x

That is,

2x = 5 × 9

Now, divide 2 on both sides:

2x/2 = (5 × 9) / 2

Here,

x = 45/2

Then,

x = 22.5

Converting this into minutes, we get 22 minutes, 30 seconds.

Divide $8.80 by 8 take that and multiply it by 23 and you get $25.30

Using the given data on the number of live multiple-delivery births for women aged 15 to 54, we need to calculate probabilities related to the age groups of the mothers. The probability of a randomly selected multiple birth involving a mother aged 30 to 39 will be determined, as well as the probabilities of not being in the age range, being less than 45, and being at least 40. Finally, we need to interpret whether a multiple birth involving a mother aged at least 40 is unusual.

(a) To calculate the probability of a randomly selected multiple birth involving a mother aged 30 to 39, we sum the number of multiple births in that age group and divide it by the total number of multiple births for women aged 15 to 54.

P(30 to 39) = 2822 / (89 + 508 + 1631 + 2822 + 1855 + 374 + 119)

(b) To find the probability of a randomly selected multiple birth involving a mother who is not aged 30 to 39, we subtract the probability found in part (a) from 1.

P(not 30 to 39) = 1 - P(30 to 39)

(c) To determine the probability of a randomly selected multiple birth involving a mother aged less than 45, we sum the number of multiple births for age groups below 45 and divide it by the total number of multiple births for women aged 15 to 54.

P(less than 45) = (89 + 508 + 1631 + 2822 + 1855 + 374) / (89 + 508 + 1631 + 2822 + 1855 + 374 + 119)

(d) To find the probability of a randomly selected multiple birth involving a mother aged at least 40, we sum the number of multiple births for age groups 40-44 and 45-54, and divide it by the total number of multiple births for women aged 15 to 54.

P(at least 40) = (374 + 119) / (89 + 508 + 1631 + 2822 + 1855 + 374 + 119)

Interpretation: The answer to part (d) will determine whether a multiple birth involving a mother aged at least 40 is unusual. If the probability is less than 0.05, it can be considered unusual. Therefore, we need to compare the calculated probability to 0.05 and select the correct choice.

Step-by-step explanation:

The combined area of the two triangular faces is \((4)(3)=12\) cm².

The area of the back rectangular face is \((3)(11)=33\) cm².

The area of the bottom rectangular face is \((11)(4)=44\) cm².

The area of the slanted rectangular face is \((5)(11)=55\) cm².

Taking the sum of these areas, the total surface area is \(12+33+44+55=144\) cm².

Answer:

b = 2

Step-by-step explanation:

Original Equation:

-12 + 3b - 1 = -5 - b

Add b to both sides

-12 + 4b - 1 = -5

Add 12 to both sides

4b - 1 = 7

Add 1 to both sides

4b = 8

Divide both sides by 4

Based on the given options, the correct answer for the confidence interval is:

c. [0.2597, 0.3403]

The confidence interval represents a range of values within which we can estimate the true population parameter with a certain level of confidence. In this case, the confidence interval suggests that the true population parameter falls between 0.2597 and 0.3403.

To calculate a confidence interval, we typically need information such as the sample mean, sample standard deviation, sample size, and a desired confidence level. Without this information, it is not possible to determine the exact confidence interval.

Subtract 4x from both sides. The right side cancels:

\(-x>8\)

Divide both sides by -1. Since we're dividing by a negative, we flip the sign:

Step-by-step explanation:

The optimal dimensions for the pasture are L = 480 meters and W = 601 meters,

A dairy farmer aims to enclose a rectangular pasture of 288,800 square meters adjacent to a river.

To minimize the amount of fencing used, we can apply the formula for the area of a rectangle (Area = length × width) and the concept of optimization.

Let's denote the length of the pasture parallel to the river as L and the width perpendicular to the river as W.

The area of the pasture is given by A = L × W = 288,800 square meters.

Since no fencing is needed along the river, we only need to minimize the perimeter P, which is P = L + 2W.

From the area formula, we can express L as L = 288,800 / W.

Substituting this into the perimeter formula gives P = (288,800 / W) + 2W.

To minimize P, we can find the critical points by taking the derivative of P with respect to W and setting it to zero. After solving for W, we can find the corresponding L.

By doing this, we find that the optimal dimensions for the pasture are L = 480 meters and W = 601 meters, which will use the least amount of fencing while providing enough grass for the herd

The p-value is less than the significance level (typically 0.05), we reject the null hypothesis and conclude that the majority of teens in this age range do not respond better to the new drug therapy for autism.

The correct answer is not provided in the question. The chi-square test statistic cannot be used for testing hypotheses about a single proportion. Instead, we use a z-test for proportions. To find the test statistic, we first calculate the sample proportion:

p-hat = 411/900 = 0.4578

Then, we calculate the standard error:

SE = \(\sqrt{[p-hat(1-p-hat)/n] } = \sqrt{[(0.4578)(1-0.4578)/900]}\) = 0.0241

Next, we calculate the z-score:

z = (p-hat - p) / SE = (0.4578 - 0.50) / 0.0241 = -1.77

Finally, we find the p-value using a normal distribution table or calculator. The p-value is the probability of getting a z-score as extreme or more extreme than -1.77, assuming the null hypothesis is true. The p-value is approximately 0.0392.

Since the p-value is less than the significance level (typically 0.05), we reject the null hypothesis and conclude that the majority of teens in this age range do not respond better to the new drug therapy for autism.

Values of p is the series convergent, ∑ (−1)ⁿ⁻¹ (ln n)^p / n³, n=2The series is convergent for p > 1.

To determine the Convergence of the series, we can apply the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges.

Let's apply the ratio test to the given series:

lim (n→∞) |((-1)ⁿ⁻¹ * (ln n)^p / n³)| / |((-1)ⁿ * (ln (n+1))^p / (n+1)³)|

Simplifying and canceling common terms:

lim (n→∞) |(ln n)^p * (n+1)³| / |(ln (n+1))^p * n³|

Taking the limit:

lim (n→∞) (ln n)^p * (n+1)³/ (ln (n+1))^p * n³

By simplifying further and applying L'Hôpital's rule:

lim (n→∞) [(ln n)^p / (ln (n+1))^p] * [(n+1)³ / n³]

= lim (n→∞) [(ln n / ln (n+1))^p] * [(n+1)³ / n³]

Since the limit of (ln n / ln (n+1)) as n approaches infinity is 1, and the limit of (n+1)³ / n³ is also 1, the overall limit is 1^p * 1 = 1.

For the series to converge, the limit must be less than 1. Therefore, we conclude that the series is convergent for p > 1.

In interval notation, the values of p for which the series is convergent are (1, ∞).

The given polynomial is :

p(x) = 5-10x​

We need to find the zeros of the above polynomial. To find it, put p(x) = 0

5-10x​ = 0

Subtract 5 from both sides

5-10x​-5=0-5

-10x=-5

or

10x=5

Divide both sides by 10.

x = 0.5 = 1/2

Hence, the zeros of the polynomial is 1/2.

Answer: Graph A represents the given inequality 3y−5x>−6. Option A is correct.

From the graphs, the graph is to choose which best describes the inequality 3y−5x>−6

Step-by-step explanation: hope this helps

Graph A represents the inequality 3y - 5x≤-6. Correct option is A. The inequality 3y - 5x ≤ -6 represents a linear inequality in two variables, y and x.

To graph this inequality, we can rearrange it into slope-intercept form (y = mx + b), where m is the slope, and b is the y-intercept.

Let's rearrange the given inequality:

3y - 5x ≤ -6

First, add 5x to both sides of the inequality:

3y ≤ 5x - 6

Now, divide both sides by 3 to isolate y:

y ≤ (5/3)x - 2

The area of the regular pentagon is approximately 732.34 square inches.

A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain.

To calculate the area of a regular pentagon, we can use the formula:

Area = (1/4) ×√(5(5 + 2√5)) × side²

the side length of the pentagon is 22.3 inches, we can substitute this value into the formula:

Area = (1/4)√(5 (5 + 2√5)) (22.3)²

Area = 732.34 square inches
