Ok, so:
For Part A, we have: P(Z|A)=P(Z and A)/P(A)
And if we replace, we got:
P(Z|A) = (0.15)/(0.25) and this is equal to 0.6.
For Part B, we have: P(A|Z)=P(Z and A)/P(Z)
P(A|Z) = (0.15)/(0.73) and this is equal to 0.205.
Answer:
Mean speed = 41.3 mph
Step-by-step explanation:
Given that,
The speeds of an automobiles are given below:
20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58
We need to find the mean speed of the cars.
Mean = sum of observations/ no. of observation

So, the mean speed of the cars is equal to 41.3 mph.
4x10^7 The number of zeros the given number has would be the exponent
Answer:
≈ 113.1 in³
Step-by-step explanation:
The figure comprises of a cylinder and a cone.
- V cylinder = bh= πr²h
- V cone = 1/3bh = 1/3πr²h
Total volume is:
- V = π*2²*8 + 1/3π2²*3 ≈ 113.1 in³
áreaBCDE = 128 cm² => BC = 8√2 cm
BC = AB√2 =>
8√2 = AB√2 =>
AB = 8 cm
