QUESTION 2 of 10: You have a budget of $3,000 to spend on a survey. If the base cost of the survey is $850 plus $4.50 per person
2 answers:
Answer:
Option A.
Step-by-step explanation:
Base cost of the survey is defined by the expression
Base cost C = 850 + 4.5x
where x = number of persons surveyed
If the budget to spend on a survey is = $3000
Then Number of person we can survey can be determined by
3000 = 850 + 4.5x
4.5x = 3000 - 850
4.5x = 2150
x =
x = 477.78
But the number of persons surveyed can not be in fraction.
Therefore, sample size we can afford is 477.
Option A. is the answer.

Answer:
Option A is correct.
Step-by-step explanation:
If Δ YES ∼ Δ NOT, then it means that ΔYES and ΔNOT are similar triangles.
The similar triangles means that all the corresponding angles of the two triangles are same i.e. ∠ Y = ∠ N, ∠ E = ∠ O and ∠ S = ∠ T
Therefore, according to the property of similar triangles we can write that
.
Therefore, option A is correct.
