Answer:
23 1/2 miles per gallon
Step-by-step explanation:
We start with dividing 329 miles with 14 gallons because it asks to find the number of miles on each gallon of gas -
Miles
----------------------------- =
Each gallon of gas
329 ÷ 14 = 23 1/2 miles per gallon
3n ¥ 2 = n ¥ 4
If 3n is cubed
9n you divide 9 by 2 then divide that answer by 4
Answer:
1067
Step-by-step explanation:
Given that:
Error (E) = 0.03
Confidence interval = 95% = 0.95
Sample size (n) = ((Zα/2) / Error)^2 * p(1 - p)
Since no assumption is given ; p = 0.5
α = 0.95
Z(1-α/2) = 1.96
(1.96 / 0.03)^2 * 0.5(1 - 0.5)
(65.333333)^2 * 0.5(0.5)
4268.4444 * 0.25
= 1067.1111
n = 1067
Answer:
15 classes
Step-by-step explanation:
Let
x -----> the number of class
y ----> the total amount in charges
we know that
The total charge is equal to the number of class multiplied by the additional fee plus the membership fee (only members)
so
<em>Members</em>
-----> equation A
<em>Non Members</em>
-----> equation B
Equate equation A and equation B
Solve for x
