Answer:
C
Step-by-step explanation:
a=
r^2
To find the radius, divide the diameter by 2
r=d/2
r=10/2
r=5
a=r^2
a=5^2
a=25
So, choice C is correct
Hope this helps! :)
Answer:
x = 95°
y = 147°
z = 128°
Step-by-step explanation:
∡x is the sum of 50 and 45, deducted from 180
∡y = 95 + 52, deducted from 180
∡z = 180 - 52

Answer:
The correct option is the first one.
Step-by-step explanation:
We know that 14 men and 24 women applied for a job. So a total of 38 persons applied for that job.
But there are 4 ways a man can be chosen. It can be the first person chosen, the second, the third of the fourth one.
So we know that the number of ways that four people can be selected out of 38 people is 38C4=73,815.
Also the number of ways 3 woman can be selected is 14*24C3 =14*2024 = 28,336.
Then, the probability of randomly selecting a group with 3 women is 28,336/73,815=0.3838
The correct option is the first one.
