Cold calls. justine works for an organization committed to raising money for alzheimer’s research. from past experience, the organization knows that about 20% of all potential donors will agree to give something if contacted by phone. they also know that of all people donating, about 5% will give $100 or more. on average, how many potential donors will she have to contact until she gets her first $100 donor?

She will have to contact a 100 persons.

Step-by-step explanation:

Working backwards, 5% of the potential 20% of donors would give more than or equal to a $100. So,

The probability of a donor giving a $100 or more = 5% * 20%

=5/100 * 20/100 = 0.01 =1%

So on average 1% of the total population called would be $100 donor. So she would need to call a 100 persons on average to get that 1 person.

answer: howdy

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
