Answer:
-9, 15
Step-by-step explanation:
Add them both together to get your answer.
Step-by-step explanation:
here's your solution
=> volume of cylinder = πr^2h
=> radius of cylinder = 12 unit
=> height of cylinder = 17 unit
=> volume of cylinder = 2448 π units^3
Answer:
The scores are between 50 and 90
Step-by-step explanation:
When we say middle 95%, we means that this value falls between 2 standard deviations of the mean i.e
μ ± 2σ
Hence,
mean of 70 and a standard deviation of 10
μ ± 2σ
μ - 2σ
70 - (2 × 10)
= 70 - 20
= 50
μ + 2σ
= 70 + (2 × 10)
= 70 + 20
= 90
Answer:
Step-by-step explanation:
a) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.8 and P(A)=0.2
Hence A and B are not independent.
b) If events A and B are independent we have
P(A/B) =P(A)
But here P(A/B) = 0.6 and P(A)=0.3
Hence A and B are not independent.
c) If events A and B are independent we have
P(A/B) =P(A)
Jere P(A/B) = 0.5 and P(A)=0.5
Hence A and B are independent.
Answer:
(f/g)(8)= f(8)/g(8)= = 65/41
Step-by-step explanation:
f(x)=3 - 2x
g(x)=1/x +5
The easiest approach is to eval first the point in every function before performing the division, thus we have that:
f(8)= 3-2*8=-13
g(8)=1/8 +5= 41/5
Now, (f/g)(8)= f(8)/g(8)= 13 / (41/5) = 65/41
