Answer:
p = 3
q = 4
Step-by-step explanation:
p + 2q = 11 --------------------(I)
p = 11 - 2q
2p + q = 10 --------------------(II)
Substitute p = 11 -2q in equation (II)
2(11 - 2q) + q =10
2*11 - 2q *2 + q = 10
22 - 4q + q = 10
22 - 3q = 10
-3q = 10 - 22
-3q = -12
q = -12/-3
q = 4
Plugin q = 4 in equation (I)
p + 2q = 11
p + 2*4 = 11
p + 8 = 11
p = 11 - 8
p = 3

Answer:
Choice D. 15.2%
Step-by-step explanation:
We have a normal...
mean u = 48
standard deviation s = 2
We want P(43 < X < 46)
We standardize.
Consider P(43 < X) = P( (43 - 48)/2 < Z) = P(-2.5 < Z)
P( X < 46) = P( Z < (46 - 48)/2 ) = P(Z < -1)
We want P( -2.5 < Z < -1)
Look at Z-scores.
P( Z < -2.5) = 0.0062
P(Z < -1) = 0.1587
so P(-2.5 < Z < -1) = P(Z < -1) - P(Z < -2.5) = 0.1587 - 0.0062 = 0.1525 = 15.2%
