Answer:

Step-by-step explanation:

r=13in

Perimeter of a circle is 2πr

P=2×22/7×13

P=81.71in.

If it will make 3 revolution then it will have move 3 times it perimeter

3×81.71

245.14in

The distance the wheel will traveled is 245.14in

Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed.
OLEGan [10]

Answer: the value of population standard deviation is 3.87

Step-by-step explanation:

From the information given,

Number of sample, n = 8

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean ± z ×standard deviation/√n

Since confidence interval = 2.694,

It becomes

2.694 = 1.96 × standard deviation/√8

Dividing both sides of the equation by 1.96, it becomes

1.37 = standard deviation/√8

Standard deviation = 1.37 × √8

Standard deviation = 3.87

Given g(x) = -X – 1, solve for x when g(x) = 3.
Vika [28.1K]

Answer:

-4 = x

Step-by-step explanation:

g(x) = -X – 1

g(x) = 3

3 = -x-1

Add 1 to each side

3+1 = -x-1+1

4 = -x

Multiply by -1

-4 = x

gregori [183]

Answer:

Dependent sample: The same textbook are being compared.

Step-by-step explanation:

We are given the following in the question:

A student wants to compare textbook prices for two online bookstores.

Sample 1 from bookstore A:

$115, $43, $99, $80, $119

Sample 2 from bookstore B:

$110, $40, $99, $69, $109

Dependent and independent sample:

  • Dependent samples are paired observations for same set of items.
  • Independent samples are observations made on two different sets of items.
  • If the values in one sample affect the observations in the other sample, then the samples are dependent.
  • If the values in one sample have no effect about those of the other sample, then the samples are independent.

Thus, the given sample is dependent sample as the same textbook is being compared from two different bookstore.
