Answer:
1006
Step-by-step explanation:
Take proportion, p = 62%
n = (Z² * pq) / M.E²
Margin error = 0.03
p = 62% = 0.62
q = 1 - p = 1 - 0.62 = 0.38
Zcritical at 95% = 1.96
n = (1.96² * (0.62*0.38)) / 0.03²
n = 0.90508096 / 0.0009
n = 1005.6455
n = 1006
Sample size = 1006
Answer:
- $5.60 sales tax
- $75.60 total cost
Step-by-step explanation:
You have correctly found the sales tax to be ...
$70.00 × 0.08 = $5.60 . . . sales tax
The total cost of the item is the selling price with the tax added:
$70.00 +5.60 = $75.60 . . . total cost
An Algebraic Expression
Hope you have a great day!
Say you have small lego bricks (lets say 2 inch in length) and large lego bricks (lets say 3 inches in length) so you want to find out how many little legos will it take to equal 4 large ones, because they are smaller you need more to create the same length as the larger one, hints multiplying.
easiest way i can think of to help you out :)
