Antwone earns money at a steady rate mowing lawns. The points (1,25) and (5,125) appear on a graph of the amount earned versus n
Volgvan
Use rise over run to find slope. If you don't know what that is, its y2-y1/x2-x1. Y2 is 125, Y1 is 25, X2 is 5, and X1 is 1. You then plug the numbers in, 125-25=100. 5-1=4. then you divide 100/4, in which you get 25. So you times 25 by 3, getting 75.

Josh examines the expression 5^-x over 5^x, where m is greater than 0.
DochEvi [55]

Answer:

Josh is wrong.

Step-by-step explanation:

5^-x / 5^x  = 5^(-x-x) = 5^-2x

= 1 / 5^2x  

 (you subtract the exponents when dividing )

So Josh is wrong  ( he would be correct if we were multiplying)

We have a null hypothesis that u=3.75, but we are reluctant to accept this as the population value in case the true value is dif
Gala2k [10]

Answer:

option A

Step-by-step explanation:

To Test

H₀ : μ = 3.75            

H₁ : μ ≠ 3.75                

now,                                        

If μ = 3.95 then it means H₀ is not true.                  

then the probability is rejecting the null hypothesis.        

Hence, the probability is the power of the test against the alternative μ=3.95                      

The correct answer is option A
