Answer:
f(x) = 2x² + 3
g(x) = x² - 7
( f - g)(x) = 2x² - x² +3 --7
= x² + 3 + 10
= x² + 10

Answer:
E 240
Step-by-step explanation:
Geometric Distribution mean = (1- p) / p
16 = (1 - p) / p
16p = 1 - p ; 17p = 1 ; p = 1/17 = 0.058
Standard Deviation = (1 - p) / p^2
= (1 - 0.058) / (0.058)^2
0.942 / 0.003364
= 280 , closest to 240
19/5=p/3-36/5
Convert the decimals into fractions
15 x 19/5=(p/3-36/5) x 15
Multiply both sides by 15
57=5x-108
5x-108+108=57+108
Add 108 to both sides
5x=165
X=33
