Answer:

she buys half a pound and we need to know how much she spends.

If 1 full pound is $3, we need to half that.

What's half of 3?

1.5

So that means that a half pound of berries costs:

$1.50

Answer:

$1.50

Step-by-step explanation:

if one pound of boysenberries is $3, and we want to find the price of half a pound, simply divide 3 in half.

3/2 = 1.50

so, 1/2 lb of boysenberries is $1.50.

If 28% of students in College are near-sighted, the probability that in a randomly chosen group of 20 College students, exactly
cluponka [151]

Answer: (D) 16%

Step-by-step explanation:

Binomial probability formula :-

P(x)=^nC_xp^x(1-p)^n-x, where n is the sample size , p is population proportion and P(x) is the probability of getting success in x trial.

Given : The proportion of students in College are near-sighted : p= 0.28

Sample size : n= 20

Then, the the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is given by :_

P(x=4)=^{20}C_4(0.28)^4(1-0.28)^{20-4}\\\\=\dfrac{20!}{4!16!}(0.28)^4(0.72)^{16}\\\\=0.155326604912\approx0.16\%

Hence, the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is closest to 16%.
