C. 5x - 2y = 16 is your answer

plug in each point into the equation.

(2, -3)

x = 2, y = -3

5(2) - 2(-3) = 16
10 + 6 = 16
16 = 16 (True)

(4,2)

x = 4, y = 2

5(4) - 2(2) = 16
20 - 4 = 16
16 = 16 (True)


hope this helps

What is the mean absolute deviation and population standard deviation of this data set? 1, 4, 6, 7, 9, 9
Alekssandra [29.7K]

Answer:

a)2.33

b) 2.83

Step-by-step explanation:

What is the mean absolute deviation and population standard deviation of this data set? 1, 4, 6, 7, 9, 9

Step 1

Find the Mean

n = 6

Mean = Sum of values/Number of value

= 1 +4 + 6 +7 + 9+ 9/6

= 36/6

= 6

a) Mean Absolute Deviation

Formula

= |x - Mean|/n

= | (1 - 6)+(4 - 6) + (6 - 6)+(7 - 6)+ (9 - 6) + (9 - 6)|/6

= 5 + 2 + 0 + 1 + 3 + 3/6

= 14/6

= 2.3333333333333

Approximately = 2.33

b) Population Standard deviation

Formula

=√(x - Mean)²/n

= √ (1 - 6)²+(4 - 6)² + (6 - 6)² +(7 - 6)² + (9 - 6)² + (9 - 6)²/6

= √25+ 4+0+ 1+ 9+9/6

= √48/6

= √8

= 2.828427125

Approximately = 2.83

AnnyKZ [126]

Answer:

The solution set is;

y < 3

This means the values of the real numbers set that are less than 3 in value

Step-by-step explanation:

Here, we want to get the solution set of the inequality

what we have to do is to get the value of y

We have this as;

15y < 36 + 9

15y < 45

y < 45/15

y < 3

A large software development firm recently relocated its facilities. Top management is interested in fostering good relations wi
Pachacha [2.7K]

Answer:

B. i and iii

Step-by-step explanation:

There are mistakes in your question. But I solve this problem using the average mean of 15 because that is what is contained in the solution

Hypothesis

H0: u <= 15

H1: u > 15

Mean of x = 16.6

S = 2.22

Test statistic used is t test

16.6 - 15 / 2.22/√24

= 3.531

We find the critical value

Degree of freedom = 24-1 = 23

This is a one tailed test

Critical value = 1.714

We find p value using Ms excel T distribution function

= 0.000894

To make the decision

3.531 > 1.714 so we conclude that

I.) Reject null hypothesis

Iii) conclude an average if more than 15 hours is volunteered per month. So no need to institute the program.

The answer option Is B
