Answer:
20
Step-by-step explanation:
half of 20 is 10.
so 20 + 10 = 30
√5/√32
Multiply both numerator and denominator by √32
√160/32
4√10/32
=√10/8
Answer:
56m²
Step-by-step explanation:
First, find the area of the entire rectangle:
10 × 8 = 80
Then, find the area of the triangle:
1/2(6)(8) = 24
Finally, subtract the two areas to find the shaded area:
80 - 24 = 56
Elise's number is 29.
If you think of multiplying a value by -3 to get -33, it would obviously be 11.
So in this case, you would want to add 18 to 11 to get Elise's number, which is 29. Subtracting 18 from 29 would get you back to the value of 11, which you can then multiply it by -3 again to get -33.
Answer:
- Total number = 30
- Number of females = 12
- Number of males = 18
a) <u>Combination of 5 out of 30:</u>
- 30C5 = 30!/[5!*(30 - 5)!] = 142506
b) <u>Combination of 2 males:</u>
- 18C2 = 18!/[2!*(18 - 2)!] = 153
<u>Combination of 3 females:</u>
- 12C3 = 12!/[3!*(12 - 3)!] = 220
<u>The number of ways with 2 males and 3 females:</u>
c) <u>Required probability is:</u>
- P(2 males and 3 females) = 33660 / 142506 = 0.236
