2. Calculate the probability that the couple conceived a girl and the test predicts a boy. 3. Calculate the probability that the couple conceived a boy and the test predicts a girl.

4. calculate the probability that the couple conceived a boy and the test predicts a boy.

5. calculate the probability that the couple conceived a girl before the test was taken. (hint: add the probabilities you found for question 1 and 2, and divide by the sum of all probabilities.)

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
