Answer:
57.5
Step-by-step explanation:
The expected frequency of West Campus and Failed :
Let :
Failed = F
East Campus = C
West Campus = W
Passed = P
Frequency of FnW :
[(FnE) + (FnW) * (PnW) + (FnW)] / total samples
[(52 + 63) * (63 + 37)] / 200
[(115 * 100)] / 200
11500 / 200
= 57.5
n(Failed n East campus)
The standard form for the given equation would be:
12x + y = 4
To solve the given problem
We can consider,
30% are girls of 30 people
70% are boys in 30 people
In order to get the number, we just multiply the total number
of people with the percentage of the designated target populace.
<span><span>1. </span>30 x 0.3 =
9 girls</span>
<span><span>
2. </span>30 x 0.7 =
21 boys</span>
<span><span>
3. </span>21 boys + 9
girls = 30 people</span>
Hence, there are 21 boys.
