Prob of selected students times prob of selecting boys times prob of selecting 3 boys
total students = 15b + 30g = 45 students
1. 10s/45t = 0.22
2. 15b/45t = 0.33
3. 3b/15b = 0.2
0.22×0.33×0.2=0.0148
1.48%
I'm not sure 100%... double check answer please
Answer:
135 cm
Step-by-step explanation:
Let Jose's height = x
The mean of their heights = 150
Given the Heights:
150cm, 170cm, 140cm, 155cm
The mean is the sum if the heights divided by the number of people
Here :
(150 + 170 + 140 + 155 + x) / 5 = 150
(615 + x) / 5 = 150
615 + x = 750
x = 750 - 615
x = 135 cm
We just need to see everything that is not x as a number.
if I asked

we would solve it by combining like terms first. but, if I tell you not to do that, we would add 9 and 7(2) to both side and end up with

we would then divide both sides by 7

math is always math... it's just how we look at it. so, do the same steps!

add 9 and 7z to both side

divide both sides by 7
Answer:
A = 94.985
Step-by-step explanation:
Formila for area of a circle is A = pi * radius²
Just plug in your numbers for: A = 3.14 * 5.5²
