Answer:
$72.80
Step-by-step explanation:
You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.
(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)
Because it's iscosceles, angle 1 is similar size to the angle on the right leg.
∠1 = 67°
The sum of interior angles in trapezoid equals to 360°.
And because it's iscosceles, the upper angles are in the same size. We can write it as,
the sum of angles = 360°
67° + 67° + ∠2 + ∠2 = 360°
134° + 2 × ∠2 = 360°
2 × ∠2 = 360° - 134°
2 × ∠2 = 226°
∠2 = 113°
Final answer
∠1 = 67°
∠2 = 113°

Answer:
C. Stratified Sampling
Step-by-step explanation:
Stratified sampling is a sampling method in which the overall population is divided into a number of smaller sub groups.
These smaller sub-groups are called as strata.
These sub-groups are formed on the basis of similar characteristics and attributes shared by the population.
It is also known as proportional random sampling.
