Answer:
1/2(6)(2 + x) = 27
3(2 + x) = 27
6 + 3x = 27
6 - 6 + 3x = 27 - 6
3x = 21
3x / 3 = 21 / 3
x = 7
Step-by-step explanation:
We have the inequality:
We can solve it by dividing each side by 8:
Answer: x<=7 (Option A).
Answer:
200
Step-by-step explanation:
15% × ? = 30
? =
30 ÷ 15% =
30 ÷ (15 ÷ 100) =
(100 × 30) ÷ 15 =
3,000 ÷ 15 =
200
Answer:
The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.
Step-by-step explanation:
For a beta distribution with α = 2 and β = 9, we need to use a calculator to compute the probabilities.
The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.
