Answer:

m = 1

c = -6

Step-by-step explanation:

m is the gradient of the line.

c is the intercept of the line.

The formula for it is : y = mx+c

so m = 1

c = -6

Hope this helps

The weights of running shoes are normally distributed with an unknown population mean and standard deviation. If a random sample
VLD [36.1K]

Answer:

The margin of error for a 95% confidence interval estimate for the population mean using the Student's t-distribution is of 6.22 ounces.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 23 - 1 = 22

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 22 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.95}{2} = 0.975. So we have T = 2.0739

The margin of error is:

M = T*s

In which s is the standard deviation of the sample.

In this question:

s = 3.

Then

M = 2.0739*3 = 6.22

The margin of error for a 95% confidence interval estimate for the population mean using the Student's t-distribution is of 6.22 ounces.

I don’t know what to do. Can you please help me.
konstantin123 [22]

Answer:

66.67 %

Step-by-step explanation:

The surface area of a cake (cylinder) = 2πr² + 2πrh

but since we are not including bottom for chocolate cake so the formula changes to = 2ℎ+²

<h3>S.A of cake </h3>

πr² + 2πrh

π4² + 2π(4)(4)

16π + 32π

48π inches

<h3>S.A of chocolate</h3>

2ℎ+²(top)

24(2) + (4)²

16 + 16

32 inches

Percentage of cake that is chocolate = S.A of chocolate/S.A of cake * 100%

Percentage of cake that is chocolate = 32 inches/48π inches * 100%

Percentage of cake that is chocolate = 66.67%

(Assuming that top of chocolate is included)
