Answer:
0.65 = 65%
Step-by-step explanation:
56% of the moviegoers were female: P(F) = 0.56
26% were under age 25: P(25-) = 0.26
17% were females under the age of 25: P(F ∩ 25-) = 0.17
Probability that a moviegoer is either female or under age 25: P(F ∪ 25-) = ?
We know that P (A ∪ B) = P(A) + P(B) - P(A ∩ B), so:
P(F ∪ 25-) = P(F) + P(25-) - P(F ∩ 25-) = 0.56 + 0.26 - 0.17 = 0.65
Answer:
I only know c I'm sorry with 16 and 26
the answe is 16÷26 = 0.61 sorry if I'm wrong.!
Answer:
c
Step-by-step explanation:
beacuse if you multiply all
H(t) = -16t² + 60t + 95
g(t) = 20 + 38.7t
h(1) = -16(1²) + 60(1) + 95 = -16 + 60 + 95 = -16 + 155 = 139
h(2) = -16(2²) + 60(2) + 95 = -16(4) + 120 + 95 = -64 + 215 = 151
h(3) = -16(3²) + 60(3) + 95 = -16(9) + 180 + 95 = -144 + 275 = 131
h(4) = -16(4²) + 60(4) + 95 = -16(16) + 240 + 95 = -256 + 335 = 79
g(1) = 20 + 38.7(1) = 20 + 38.7 = 58.7
g(2) = 20 + 38.7(2) = 20 + 77.4 = 97.4
g(3) = 20 + 38.7(3) = 20 + 116.1 = 136.1
g(4) = 20 + 38.7(4) = 20 + 154.8 = 174.8
Between 2 and 3 seconds.
The range of the 1st object is 151 to 131.
The range of the 2nd object is 97.4 to 136.1
h(t) = g(t) ⇒ 131 = 131
<span>It means that the point where the 2 objects are equal is the point where the 1st object is falling down while the 2nd object is still going up. </span>
4280 because 75+5+4200= 4280
