Based on the data in the table, if a cow is randomly selected from farm B, the probability that its feed includes seaweed is 0.597 (Option D) and without is 0.57

Note that the total number of feed with sea weed is 74.
And the total number of cows on the farm B is 124.

Thus, the cows whose feed includes seaweed is 74/124

= 0.59677419354

≈ 0.597

The Probability of those whose feed is without sea weed is

Note that the total number of feed without sea weed is 40.
And the total number of cows on the farm B is 76.

Thus, the probability is 40/70
= 0.5714285714

≈ 0.571

When a line segment is drawn from a point on a circle's circumference, through the center to another point on the circle's circumference, the distance of the line segment is equal to the diameter of the circle.

The diameter is defined as any straight line passing through the center of a circle, connecting two points on the circumference. It is the longest chord of the circle and is also the length of a circle's widest point.

The diameter is an important parameter of a circle, as it determines the circle's size and area. It is related to the circle's radius, which is half the length of the diameter. The diameter is also used in various formulas for calculating the circumference, area, and other properties of circles.

Answer:

\( \large{ \bold{f(-2)=9}} \)

Step-by-step explanation:

In order to find f(-2) we substitute the value of x that's -2 into f(x). That is wherever there is x in f (x) you replace it by -2 and solve.

We have

\( \large{f(-2) = -3 - 6(-2)\\= -3--12 = -3+12 = 9} \)

We have the final answer as

\( \large{f(-2)=9} \)

The amount of overtime that Diego would earn would be D. $ 148. 50.

Diego's regular rate is $11 per hour. When he works overtime, he is paid time-and-a-half of his regular rate, which means he earns an additional 50% of his regular rate for each hour of overtime.

So his overtime rate is:

= 11 + ( 11 x 0.5)

= 11 +  5.50

= $16.50 per hour

If Diego works 9 hours of overtime in a week, he would earn:

= 9 x 16.50

= $ 148. 50

In conclusion, if Diego was to work 9 hours of overtime, he would be paid $ 148. 50 for his efforts.

Answer: it’s says the equation is solved here’s the graph

Step-by-step explanation:

The appropriate null and alternate hypotheses are Null hypothesis (H0) and Alternate hypothesis (Ha).

The mean operating cost per hour using the current production method is $220. The mean operating cost per hour using the new production method is less than $220.

Type I error in this situation is rejecting the null hypothesis (H0) when it is actually true. This means concluding that the new production method reduces the mean operating cost per hour when it really doesn't. It is also known as a false positive or alpha error. This type of error can occur due to chance or statistical significance level (alpha) set too high.

We need to first find the equation of the line l1 in vector form or parametric form. Without the equation of the line, we cannot determine if it lies on, intersects or does not intersect the surface.

Once we have the equation of the line, we can substitute the coordinates of the line into the equation of the surface, and see if there exists a solution.

Please provide more information about the line l1 so that we can solve the problem.

Step-by-step explanation:

They gave you the area.  The area of a square is length times width.  Since all the sides are the same length.  You are looking for what number multiplied by itself would be \(\frac{1}{64}\).

The side length will be \(\sqrt{\frac{1}{64} }\)  Which would be \(\frac{1}{8}\).

\(\frac{1}{8}\) x \(\frac{1}{8}\) would be \(\frac{1}{64}\)

The answer is B, Graph B is the linear graph

Answer:

The table will be:

x            y = 2x²         y = 2ˣ

0            0                   1

1             2                  2

2             8                  4

Step-by-step explanation:

Given the non-linear  equations

y = 2x²

y = 2ˣ

y = 2x²                              

y = 2(0)² =0

y = 2ˣ

y = 2⁰ = 1

y = 2x²                              

y = 2(1)² = 2

y = 2ˣ

y = 2¹ = 2

y = 2x²                              

y = 2(2)² = 8

y = 2ˣ

y = 2² = 4

Thus, the table will be:

x            y = 2x²         y = 2ˣ

0            0                   1

The 95% confidence interval of .61 to 1.19 cm provides strong evidence that there is a difference in mean head circumference between babies of mothers who used marijuana during pregnancy and those who did not. Furthermore, the small p-value suggests that the mean difference is statistically significant, and is not likely to be zero.

The 95% confidence interval for the difference in mean head circumference between babies of mothers who used marijuana during pregnancy and those who did not is .61 to 1.19 cm. This implies that the true mean difference is likely to be between .61 and 1.19 cm. The p-value is a measure of how likely it is that the difference in means is zero, and can be used to assess the statistical significance of the difference in means.

Therefore, the p-value for the hypothesis that the mean difference is zero is very small and can be considered statistically significant.

The small p-value suggests that the mean difference is statistically significant, and is not likely to be zero.

A 95% confidence interval (CI) is a range of values that is expected to include the true population mean with a probability of 0.95. The CI for the difference in mean head circumference between non-users and users of marijuana during pregnancy is 0.61 to 1.19 cm.

This means that the sample mean difference (nonuse minus use) falls within this interval.

If the true population mean difference were zero, the sample mean difference would fall within the range of random sampling error, and the null hypothesis that there is no difference between the groups would be supported.

However, since the 95% CI does not include zero, we can conclude that the difference is statistically significant at the 0.05 level.
