Time he spends on both instruments = x + y.
This is equal or greater than 45, so the inequality is:-
x + y >= 45
Answer:
0.81
Step-by-step explanation:
P(success) = 0.9
P(failure) = 1 - 0.9 = 0.1
Binomial probability:
P(X=n) = nCr (0.9)^n (0.1)^r
Here, n=2 and r=0:
P(X=2) = ₂C₀ (0.9)² (0.1)⁰
P(X=2) = 0.81
Answer:
(3,-3)
Explanation:
create an equation set equal to zero:
3×(1,-1)=0
distributive property:
3×1= 3 ; 3× -1= -3
(3,-3)=0
Answer:
It's linear
Step-by-step explanation:
This is a slope intercept form.
