Answer:
it depends how much the cds cost.
Answer:
-33/10 or -3.3
Step-by-step explanation:
Using a z-score table:
P(z<1.87)=0.96926
P(z<1.87)=0.96926 x 100%
P(z<1.87)=96.926%
f(x)= 3^(x+4)
f(2)= 3^(2+4)
do the bracket first
(2+4)= 6
3^6 - 3*3*3*3*3*3 - because of the exponent
3*3*3= 27
3*3*3= 27
27*27
