Answer:
P(A^B) = 22/15 or 1 7/15
Step-by-step explanation:
To find the P (A^B), we add the probability of events A and B.
2/3 + 4/5 = P, we need to find the LCD to add disimilar fractions
LCD is 15.
2(5)/15 +4(3)/15 = 10/15 + 12/15 = 22/15
Answer:
14
Step-by-step explanation:
8:14
8 adults 14 children
If you want to know her percentage, we do:
16 ÷ 25 = 0.64
0.64 × 100 = 64%
Her score is 64%
Z-scores (left tail) of a given variable X are calculated by
Z(x)=(x-mean)/standard deviation.
For Mary:
Zm(124)=(124-110)/8=14/8=1.75
For Carrie:
Zc(289)=(289-250)/20=39/20=1.95
therefore
Zc>Zm
1 inch = 48 miles. Therefore, 2.5 inches = 2.5X48= 120miles
