natta225 [31]3 years ago
4 0

Answer:

-4=x

Step-by-step explanation:

f(x) = -3x + 6

Let f(x) = 18

18 = -3x+6

Subtract 6 from each side

18-6 = -3x+6-6

12 = -3x

Divide each side by -3

12/-3 = -3x/-3

-4=x

(5,12)and (2,6) rate of change?<br> Initial value?<br> HURRY i NEED this done.
Otrada [13]

Answer:

Part 1) The rate of change is 2

Part 2) The initial value is 2

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(5,12)and (2,6)

substitute the values in the formula

m=\frac{6-12}{2-5}

m=\frac{-6}{-3}

m=2

therefore

The rate of change is 2

step 2

Find the initial value

we have

m=2

point\ (2,6)

substitute in the equation y=mx+b

6=2(2)+b

solve for b

6=4+b

b=2 ---> initial value

The linear equation is equal to

y=2x+2

The y-intercept or initial value is 2

Suppose that the hourly wages of fast food workers are normally distributed with an unknown mean and standard deviation. The wag
Nutka1998 [239]

Answer: 1.303639

Step-by-step explanation:

The t-score for a level of confidence (1-\alpha) is given by :_

t_{(df,\alpha/2)}, where df is the degree of freedom and \alpha is the significance level.

Given : Level of significance : 1-\alpha:0.80

Then , significance level : \alpha: 1-0.80=0.20

Sample size : n=40

Then , the degree of freedom for t-distribution: df=n-1=40-1=39

Using the normal t-distribution table, we have

t_{(df,\alpha/2)}=t_{39,0.10}=1.303639

Thus, the t-score should be used to find the 80% confidence interval for the population mean =1.303639
