Answer:

Below

Step-by-step explanation:

First, find the difference. You would do

-19 - (-9) = -10

-9 - 1 = -10 and so on...

The difference is -10

Now you need to find what number will make 11 when added to -10.

11 - (-10) = 21

The equation:

y = -10x + 21

Answer:

175

Step-by-step explanation:

The sample size n in Simple Random Sampling is given by

$\bf n=\frac{z^2s^2}{e^2}$

where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation.

Replacing values

$\bf n=\frac{(1.96)^2(675)^2}{(100)^2}=175$

So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000

Write an equation of the line that passes through the given point and is parallel to the given line.

saveliy_v [14]

the equation of line passing through given point parallel to y = -2x+7 is: $y = -2x+9$

Step-by-step explanation:

Given equation of line is:

$y = -2x+7$

As the given line is in slope intercept form, the coefficient of x is the slope

Let m1 be the slope of given line

$m_1 = -2$

Let m2 be the slope of second line then

$m_2= -2$

The equation of line is given by:

$y= m_2x+b$

Putting the value of slope

$y = -2x+b$

Putting the point (4,1) in the equation

$y = -2x+b\\1 = -2(4)+b\\1= -8+b\\b = 1+8\\b = 9$

Putting the value of b in the equation

$y = -2x+9$

Hence,

the equation of line passing through given point parallel to y = -2x+7 is: $y = -2x+9$

Help asap 25 points worth pre alg x= y=

Mumz [18]

Answer:

Firstly Substitute y=2x-5 into 5x-4y=-10

This will be 5x-4(2x-5)=10 now solve for x

5x-8x+20=-10

-3x=-30

X=10

Now sub x as 10 into the second equation y=2x-5

Y=2(10)-5

Y=15
