Answer:
120 yd2
Step-by-step explanation:
I assume you are solving for area.
The formula for a paralellogram (what it appears to be) is base times height.
The base in this equation is 10, and the height is 12. Multiplying this you get 120 yards squared.
For perimeter, you use pythagorean theorem to get the diagonal. . Then multiply 10 and
by two, and then add them.

Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion = 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
(From the z tables)
The margin of error is calculated by using the formula:
M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%
