what do you need help on
Step-by-step explanation:
what
For this Q:
mean=31
st.dev.=0.8
x=32
Calculate z-score:
z=(x-m)/s = (32-31)/0.8=1.25
This z-score value corresponding to the probability of 0.8944

Y - 24 = -0.6 (x - 1)
y - 24 = -0.6x + 0.6 add 24 to both sides
y - 24 + 24 = -0.6x + 0.6 + 24
y = -0.6x + 24.6 add 0.6x to both sides
0.6x + y = -0.6x + 0.6x + 24.6
0.6 x + y = 24.6
Answer:
f(-8) = 64
Step-by-step explanation:
Since x =-8, we need to use x^2 since -8 <0
(-8)^2 = 64
When x = -8 f(-8) = 64
