Seven people, named Anna, Bob, Chandra, Darlene, Ed, Frank, and Gina, will be interviewed for a job. The interviewer will choose two at random to interview on the first day. What is the probability that Anna is interviewed first, and Darlene is interviewed second?

Answers

Answer 1

Answer:

0.0238

Step-by-step explanation:

Total number of persons to be chosen from = 7

If each person has an equal probability of being selected ;

Number of persons to be selected = 2

Probability = required outcome / Total possible outcomes

P(Anna first) = 1 / 7

Recall; this is a selection without replacement ;

P(Darlene second) = 1 / 6

1/7 * 1/ 6 = 1 / 42 = 0.0238

Please help, math question

Answers

B is correct because when you factor it out you are trying to get something that equals that. So 4xx3=12x+2x from x x 2 then the 4x and x mutiply to be 4x^2 then the two and three mutiply to be six. Hope o helped.

Line m has a y-intercept of c and a slope of q/p, where p > 0, q > 0, and p ≠ q.What is the slope of a line that is perpendicular to line m?

Answers

Answer:

-p/q

Step-by-step explanation:

m1 = Slope of line 1 (Line m) = q/p

m2 = Slope of line 2

Since the lines are perpendicular,

m1•m2 = -1

Therefore,

m2 = -1/m1

m2 = -1/(q/p)

m2= -p/q

Thanks.

In your own words, explain the
term midpoint.

Answers

Ok in my own words hmm.

Midpoint to me would be the point in the middle.

I've seen and worked with midpoints on lines and triangles.

So the midpoint would be the point in the middle of a line segment.

Hope this is helpful!

Justin weighs 15 pounds less than Greg weighs. Half of Greg’s weight is 75 pounds less than Justin’s weight. How much does each of them weigh? Greg weighs 200 pounds, and Justin weighs 185 pounds. Greg weighs 190 pounds, and Justin weighs 175 pounds. Greg weighs 180 pounds, and Justin weighs 165 pounds. Greg weighs 170 pounds, and Justin weighs 155 pounds.

Answers

J=G-15
(G/2)=J-75

Substitute
(G/2)=G-15-75
G/2 =G-90
G-G/2= 90
G/2=90
G=180

J=G-15=180-15=165

Greg weighs 180 pounds, and Justin weighs 165 pounds.

Answer:

180 and 165
