Answer:
15
Step-by-step explanation:
No need for the diagram (though it helps)
P(AUB) = P(A) + P(B) - P(A and B),
P(A) = 0.61 - 0.41 + 0.18 = 0.38
So, D!!
Answer:
Step-by-step explanation:
<u>The scale is</u>
- 1/8 in = 10 miles
- 1/8*8 in = 10*8 miles
- 1 in = 80 miles
<u>Then</u>
<u>Cross multiplication</u>
- x - 248
- 1 - 80
- x = 248/80 = 3.1 in
Answer:
Step-by-step explanation:
<u>Mean of the data = sum of the data / number of frequencies:</u>
- (40 + 38 + y + y + x + 32)/6 = 36
- 2y + x + 110 = 36*6
- 2y + x = 216 - 110
- 2y + x = 106
Correct choice is d
