Answer:

Step-by-step explanation:

Given

Let w is income of women and m is income of men

Woman haircut = $45

Men haircut = $15

Women shampoo = $12

Men shampoo = $7

The income from men and women getting a haircut and a shampoo is

Income = number of women*(haircut price and shampoo price) + number of men*(haircut price and shampoo price)

income = m($45 + $12) + w($15 + $7)

income = w($57) + m($22)

Answer:

92.5

Step-by-step explanation:

Lets say, first number = x


Second number = 3x+7


Total = 49



(x)+(3x+7)= 49


4x+7 = 49


4x = 42


x = 42/4


x= 10.5



x= 10.5


3x+7 = 3(10.5)+7 = 92.5



Hope this helps!!

The American Water Works Association reports that the per capita water use in a single-family home is 74 gallons per day. Legacy
Lunna [17]

Answer:

Reject H0 since test statistic <-2.492

Step-by-step explanation:

Given that the American Water Works Association reports that the per capita water use in a single-family home is 74 gallons per day.

n = 25

x bar = 69

s= 8.3

std error = s/sqrt n = \frac{8.3}{5} \\=1.66

H0:\bar x = 74

Ha: \bar x

(Left tailed test at 5% significance level)

a) Reject H0 if t\leq-2.492

b) Test statistic = mean difference/std error

= \frac{69-74}{1.66} \\=-3.012\\

=-3.01

df =24

c) Reject H0
