sasho [114]

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

=P(Y\geq 1) where Y is binomial with p = 0.72

= 1-(1-0.72)^7\\=0.9999

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

=P(x\geq 1) =1-P(0)\\= 1-(1-0.28)^7\\=0.8997

Examine the system of equations. −5x + 5y = 40 4x + 3y = 24 What is the solution?
Solnce55 [7]
-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

75 out of 300 oranges in a basket are bad. what percent age of the oranges are (a) bad (b)good
Likurg_2 [28]

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
