Answer:

J. 2( x - 3 ) = 22

Step-by-step explanation:

All you need to do, is substitute the x with 14

2 ( x - 3 ) = 22

2 ( 14 - 3 ) = 22

use PEMDAS

2 * 14 - 2* 3 = 22

28 - 6 = 22

22 = 22

So this problem is the correct one

Hope this helped!

P.S Do you want me to show you the work for the others so you can see how I know there wrong?

Answer:point slope form

y-y1=m(x-x1)

slope-intercept form

y=mx+b

slope formula

Terry is skiing down a steep hill. Terry's elevation E(t)

in feet after t seconds is given by E(t) = 2000 − 90t.

Write a complete sentence describing Terry's starting elevation and how it is changing over time.

Terry starts at an elevation of 2000 feet and descends at 90 feet per second.

If the graphs of two linear functions are perpendicular, describe the relationship between the slopes and the y-intercepts.

slope: negative reciprocals of one another.

y-intercept: There is no relationship.

How do you evaluate the function f(x)=x+6 when x = -2,0 & 5? (step by step please!)

blagie [28]

Answer:

f(-2) = 4

f(0) = 6

f(5) = 11

Step-by-step explanation:

f(x)=x+6 when x = -2

Substitute x=-2

f(-2) = -2+6

f(-2) = 4

f(x)=x+6 when x = 0

Substitute x=0

f(0) = 0+6

f(0) = 6

f(x)=x+6 when x = 5

Substitute x=5

f(5) = 5+6

f(5) = 11

Construct a 99% confidthence interval for the population mean .Assume the population has a normal distribution. A group of 19 ra

Kobotan [32]

<h2>Answer with explanation:</h2>

Confidence interval for mean, when population standard deviation is unknown:

$\overline{x}\pm t_{\alpha/2}\dfrac{s}{\sqrt{n}}$

, where $\overline{x}$ = sample mean

n= sample size

s= sample standard deviation

$t_{\alpha/2}$ = Critical t-value for n-1 degrees of freedom

We assume the population has a normal distribution.

Given, n= 19 , s= 3.8 , $\overline{x}=22.4$

$\alpha=1-0.99=0.01$

A) Critical t value for $\alpha/2=0.005$ and degree of 18 freedom

$t_{\alpha/2}$ = 2.8784

B) Required confidence interval:

$22.4\pm ( 2.8744)\dfrac{3.8}{\sqrt{19}}\\\\=22.4\pm2.5058\\\\=(22.4-2.5058,\ 22.4+2.5058)=(19.8942,\ 24.9058)\approx(19.9,\ 24.9)$

Lower bound = 19.9 years

Uppen bound = 24.9 years

C) Interpretation: We are 99% confident that the true population mean of lies in (19.9, 24.9) .

What is the mean of the numbers 5,5,7,5,9,11,18?

AlekseyPX

It would be 6/7. Because first you would add 5+5+7+5+9+11+18 which equals 60. After that, you would divide 60 to 7. You should get 6/7. I hope this helped you!
