To find the slope you have to use this formula:

$\frac{y2-y1}{x2-x1}$

First chose any 2 random points from the graph, im gonna chose (0,1) and (-4,4). It doesn't matter which one is the x1 or x2, what matter is they have to be in the same order, you can't have (-4,4) as a (x1,y2), That's wrong.

$\frac{(1)-(4)}{4-0}$

= -3/4

This answer seems really hard but just don't overthink it. You pretty much don't have to do any math. It took me forever to do this because I was thinking so hard but i re-read it and the answer was right infront of me.

Which transformation from the graph of a function f(x) describes the graph of g(x) =10f(x)

Elanso [62]

Multiplying a function by a constant factor (10 in this example) stretches the graph relative to the x-axis. If f(x) would be a sine, you would blow up the amplitude from -1..+1 to -10..+10.

Cerrena [4.2K]

Answer:

hello your question is incomplete below is the complete question

Find the minimum sample size n needed to estimate μ For the given values of c, σ, and E. c=0.98, σ=6.5, and E=22 Assume that a preliminary sample has at least 30 members.

Answer : 48

Step-by-step explanation:

Given data:

E = 2.2,

std ( σ ) = 6.5

c ( level of confidence ) = 0.98

To find the minimum sample size

we have to first obtain the value of $Z_{a/2}$

note : a can be found using this relation :

( 1 - a ) = 0.98 ----- equation 1

a = 1 - 0.98 = 0.02

hence: a/2 = 0.01

This means that P( Z ≤ z ) = 0.99 the value of z can be found using the table of standard normal distribution. from the table the value of z = 2.33

P( Z ≤ 2.33 ) = 0.99

To obtain the sample size n

$n = (\frac{std*z}{E} )^{2}$

n = $(\frac{6.5*2.33}{2.2} )^2$ = (6.88409)^2

Therefore n ≈ 48
