Answer:
0.8997, 0.9999
Step-by-step explanation:
Given that among 46- to 51-year-olds, 28% say they have called a talk show while under the influence of peer pressure.
i.e. X no of people who say they have called a talk show while under the influence of peer pressure is binomial with p = 0.28
Each person is independent of the other and there are only two outcomes
n =7
a) the probability that at least one has not called a talk showcalled a talk show while under the influence of peer pressure

where Y is binomial with p = 0.72

b) the probability that at least one has called a talk showcalled a talk show while under the influence of peer pressurepeer pressurethe probability that at least one has not called a talk showcalled a talk show while under the influence of peer pressure

-5x + 5y = 40 -20x +20y =160 -5x + 5(8) = 40
4x + 3y = 24 20x +15y =120 -5x + 40 = 40
35y = 280 -5x =0
y = 8 x = 0

Answer:
a) 25% are bad
b) 75% are good
Step-by-step explanation:
We know that there are 300 oranges total and that 75 are bad. That means that the rest are good (implied).
300 - 75 = 225 good oranges.
So to find the percentage we have to take the selected amount divided by the total amount.
Bad Apples: Good Apples:
75 / 300 = 0.25 225/300 = 0.75
However, that's a decimal or <em>a number out of 1, </em>we need a percent or <em>a number out of 100.</em> So we have to multiply both numbers by 100.
Bad Apples = 25%
Good Apples = 75%

Answer:
The answer to your question is the letter A) 470 u²
Step-by-step explanation:
Data
HJ = 32
KL = 15
height = 20
Formula
Area of a trapezoid = (long base + small base) height / 2
Substitution
Area of a trapezoid = (32 + 15)20/2
Simplification
Area of a trapezoid = (47)(10)
Result
Area of a trapezoid = 470 u²
