Answer:
i think it on of these C. y = 2x2 - 6x + 80
D. y = 2x2 + 6x - 80
Step-by-step explanation:
P(2 aces) = (1/13)^2
P(2 kings) = (1/13)^2
P(king and ace) = 8C2/52C2 - 2(1/13)^2 = 0.0152
Answer:
2sinθ + cosθ = 2
Step-by-step explanation:
12 cos θ - 16 sinθ = 0
=> 3 cos θ -4 sin θ = 0
=> tanθ = 3/4
let P = 3x
B = 4x
=> H= 5x
=> sinθ = P/H = 3/5
cosθ = B/H = 4/5
2sinθ + cosθ
= 2× 3/5 + 4/5
= 6/5+4/5
= 10/5
= 2
=> 2sinθ + cosθ = 2
The percentage of births that occurred among women between the ages of 40 and 42 is 26.41%
<h3>Calculations and Parameters</h3>
First, we would add up the ages of the mothers
27 +98+239+326+389+436+468+490+460+387+286+180+102+48+19+5+1
= 3961
Thus, to find the percentage of births occurring among women between the ages of 40 and 42 was:
102+48=150
3961/150= 26.41%
