Answer:
$62.22
Step-by-step explanation:
Let m represent the pre-tax, pre-tip price of the meal. Then the total cost is ...
m + tax + tip
= m + 7%·m +15%·m
= m(1 +7% +15%) = 1.22m
= 1.22($51) = $62.22
The total cost of the meal is $62.22.
Answer:
5.6 meters
Step-by-step explanation:
V = pi r^2 h
We want to solve for h
Divide each side by pi r^2
V/ pi r^2 = pi r^2 h/ pi r^2
V/ pi r^2 =h
We know v = 440 pi = 22/7 and r = 5
440 / ( 22/7 * 5^2) = h
440 / (22*25/7) = h
440*7/550 = h
5.6 = h
It must be an equation in order to be solved for example, 3x+5=11 then x would be 2
Its the last option they both are as far from 0 on the number line
Hope this helps and good luck on ur guyss exams :)
Answer:
b. 1.15
Step-by-step explanation:
The z statistics is given by:
In which X is the found proportion, p is the expected proportion, and s, which is the standard error is 
Out of 53 teachers who replied to the survey, 13 claim they are satisfied with their job.
This means that 
She find that the proportion of satisfied teachers nationally is 18.4%.
This means that 
Standard error:
p = 0.184, n = 53.
So
Z-statistic:
The correct answer is:
b. 1.15
