Question says that there are two type of pans.

First pan has diameter of 9 inches.

Second pan has dimension 8 inches by 11 inches. Which means second pan is rectangular.

It seems you missed few parts of the question like what we have to do with it. I searched for similar question on internet and found that they are finding surface area of the both pans so i will tell you how to find that.

Radius of the circular pan = diameter/2 = 9/2 = 4.5 inches

Then surface area of the first (circular) pan = \pi r^2 = 3.14 *4.5^2 = 63.585 square inches.

Now surface area of second (rectangular) pan is given by formula of area of rectangle

Area = Length * width = 8*11= 88 square inches.

Which equation represents the relationship between the side length, x, and the perimeter, y? y = one-fourth x y = 4x y = x + 13.

elixir [45]

Answer: B.

Y = 4x

Step-by-step explanation:

Given that the side of a shape is x

The perimeter of the shape is y

Perimeter of a rectangle can be expressed as:

P = 2L + 2W

Where L = length and W = width

But if the shape is a square, and the side of the shape is x, then, the perimeter will be

P = 4x

Where perimeter P = Y

Therefore, perimeter Y will be;

Y = 4x

Therefore, the correct answer is B which is:

Y = 4x

Weight of a rock: In a geology course, students are learning to use a balance scale to accurately weigh rocks. One student plans

statuscvo [17]

Answer:

The student who weighted the rock 5 times has a 95% confidence interval of (25.2, 29.1) which is guaranteed to be more wider (less precise) than the other student who weighted the rock 20 times.

Step-by-step explanation:

What is Confidence Interval?

The confidence interval represents an interval that we can guarantee that the target variable will be within this interval for a given confidence level.

The confidence interval is given by

$CI = \bar{x} + t_{\alpha/2}(\frac{\sigma}{\sqrt{n} } ) \\$

Where $\bar{x}$ is the mean weight $\sigma$ is the standard deviation $t_{\alpha/2}$ is the critical value from t-table and n is the sample size.

The term $t_{\alpha/2}(\frac{\sigma}{\sqrt{n} } )$ is known as margin of error.

As the sample size is decreased the corresponding margin of error increases which results in wider confidence interval which means smaller precision.

The student who weighted the rock 5 times has a 95% confidence interval of (25.2, 29.1) which is guaranteed to be more wider (less precise) than the other student who weighted the rock 20 times.

We can say with 95% confidence that the true mean weight of the rock is within the interval of (25.2, 29.1).
