which is more, 6 miles or 31,678 feet ?

Answer:

The t-statistic for a hypothesis test that is designed to answer the question is 2.4.

Step-by-step explanation:

Our test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the saple and n is the size of the sample.

A store manager designs a new accounting system that will be cost effective if the mean monthly charge account balance is more than $50.

This means that [tex]\mu = 50[/tex]

A sample of 100 accounts is randomly selected. The sample mean balance is $56 and the sample standard deviation is $25.

This means that [tex]X = 56, s = 25, n = 100[/tex]. So

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

[tex]t = \frac{56 - 50}{\frac{25}{\sqrt{10}}[/tex]

[tex]t = \frac{6}{2.5}[/tex]

[tex]t = 2.4[/tex]

The t-statistic for a hypothesis test that is designed to answer the question is 2.4.

Answer:

-9

Step-by-step explanation:

-6 Divided By 2/3 = -9

2/3 multiplied by -9 = -6

Your  answer will be z = -6/3 or -9

Answer:

The value of the test statistic is -0.97

Step-by-step explanation:

This test is two tailed test.

Null and Alternative hypothesis is as follow

Null Hypothesis is used when it is assumed that there is no significant difference between the values.

Null Hypothesis = [tex]H_{0}[/tex] = [tex]\mu =[/tex] 59.8

The Alternative hypothesis is the alternative of the Null Hypothesis. It is an experimental technique that is used when it is assumed that there is some difference

Alternative Hypothesis = [tex]H_{a}[/tex] = [tex]\mu \neq[/tex] 59.8

Test statistcs is z

The value of test statistics can be calculated using the following formula

Test Statistics [tex]= (\bar x - \mu ) / \sigma / \sqrt n[/tex]

Test Statistics [tex]= (59.7-59.8) / 1.3 / \sqrt 160[/tex]

Test Statistics = -0.97

Answer:

a. d < 11

Step-by-step explanation:

4 + d < 15

d < 15 - 4

d < 11

Answer:

Step-by-step explanation:

5x-(x-18)=6-2(x+15)

5x-x+18=6-2x-30

6x=-42

x=-7

The equivalent value of the expression is x = -7

Given data ,

Let the equation be represented as A

Now , the value of A is

5x - ( x - 18 ) = 6 - 2 ( x + 15 )

On simplifying the equation , we get

5x - ( x - 18 ) = 6 - 2 ( x + 15 )

So , the left hand side of the equation is equated to the right hand side by the value of 6 - 2 ( x + 15 )

Opening the parenthesis on both sides , we get

5x - x + 18 = 6 - 2x - 30

From the distributive property , we get

5x - x + 18 = 6 - 2x - 30

On further simplification , we get

4x + 18 = -2x - 24

Adding 2x on both sides , we get

6x + 18 = -24

Subtracting 18 on both sides , we get

6x = -24 - 18

6x = -42

Divide by 6 on both sides , we get

x = -42/6

x = -7

Therefore , the value of x = -7

Hence , the expression is x = -7

a triangle with sides measuring 20, 21, and 29

Step-by-step explanation:

As, √(20)²+(21)² = √400+441 = √841 = 29

The longest side is taken as the hypotenuse. So 29 is the hypotenuse. Which by using Pythagoras' theorem gives us 29 ( h=√b²+p² )
