Answer:0.8413
Step-by-step explanation:
Mean= 188, Std Dev. =20.8, Z=(x-mean)/Std Dev
P(X less than 167.2)= P(Z less than (167.2-188)/20.8)
=P(Z less than (-20.8/20.8))
=P(z less than -1)= P(Z less 1)
The value of 1 in the normal distribution table is 0.3413
So we add 0.5 to 0.3413 =0.8413
Answer:
9x - 5y = 29
9*1 - 5y = 29
-5y = 20
y = -4
B. -40°F
its- clearly lower than -30

-2
5n+3= -10
5n = -13
n = -13/5
= -2.6
question is integer
so answer is -2
