Answer:
C. 14
Step-by-step explanation:
F(x) = ∫₀²ˣ √(t³−15) dt
Use second fundamental theorem of calculus:
F'(x) = √((2x)³−15) d/dx (2x)
F'(x) = 2 √(8x³−15)
Evaluate at x=2:
F'(2) = 2 √(8×2³−15)
F'(2) = 2 √(64−15)
F'(2) = 2 √49
F'(2) = 14
2*(-11) if its multiple choice but im not sure
Answer:
Step-by-step explanation:
Two things to note;
1. Since there's only one 2 or hearts and one 3 of clubs
2. The first card is replaced after it's drawn
Probability of 2 of hearts = 1/52
Probability of 3 of clubs = 1/52
They both have the same probability of being drawn.
If 81=n-3(-5+4n)
81= n+15-12n
81= -11n+15
-11n=81-15
-11n=66
n=-6
