Answer:
A unit rate has a denominator of 1 unit when the rate is written as a fraction. To write a rate as a unit rate: divide the numerator and the denominator of the rate by the denominator. Example #1: A rate compares two quantities of different units. Each part of the rate must be labeled!

<span>Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-2p' to each side of the equation.
-12 + -6p + -2p = 12 + 2p + -2p
Combine like terms: -6p + -2p = -8p
-12 + -8p = 12 + 2p + -2p
Combine like terms: 2p + -2p = 0
-12 + -8p = 12 + 0
-12 + -8p = 12
Add '12' to each side of the equation.
-12 + 12 + -8p = 12 + 12
Combine like terms: -12 + 12 = 0
0 + -8p = 12 + 12
-8p = 12 + 12
Combine like terms: 12 + 12 = 24
-8p = 24
Divide each side by '-8'.
p = -3
Simplifying
p = -3

Answer:
H0: u1 - u2 = 0
H1: u1 - u2 ≠ 0
Step-by-step explanation:
This question requires us to state the hypothesis to be used for this test to know if males and females have the same amount of substance X. I have gone further to also calculate the test statistics too.
Null hypothesis:
H0: u1 - u2 = 0
Alternative hypothesis:
H1: u1 - u2 ≠ 0
X1 = 28, sd1 = 14.1, n1 = 75
X2 = 33, sd2 = 9.5, n2 = 50
We have a 2 tailed test
Alpha = 1-0.8812
= 0.1188
Critical value = 1.56
If z<-1.56 or z>1.56
Reject null hypothesis
Test statistic
= (28-33)/14.1²/75 + 9.5²/50
= -2.37
Therefore we reject the H0 because -2.37 is less than -1.56

Step-by-step explanation:
since the internet usage is more than 4 hrs, the second equation will be used. that is
cost = (10 + 2.50 (x - 4)) where x is the usage hours.
thus
