The correct question is:
What is the probability that 2 girls and 2 boys will be selected?
Solution:
Total number of students = 10
Ways to select a team of 4 students = 10C4 = 210
2 Boys can be selected from 6 boys in ways = 6C2 = 15
2 Girls can be selected from 4 girls in ways = 4C2 = 6
Number of ways to select 2 boys and 2 girls = 15 x 6 = 90
Probability of choosing 2 boys and 2 girls = 90/210 = 3/7
Thus, if 4 team members are selected, the probability of choosing 2 boys and 2 girls will be 3/7
625000
That’s the answer:)
(women who prefer mountains)/(total women) = 0.302/(0.302 + 0.236)
= 0.302/0.538 ≈ 0.561 = 56.1%
Answer:
4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
I hope this helps!
