Answer:

Sam's thinking was incorrect.

A certain company sends 35% of its overnight mail parcels via express delivery service 1 and the rest by express delivery servic
sineoko [7]

Answer:

55.32% probability that a late package was delivered by express delivery service 2

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

P(B|A) = \frac{P(B)*P(A|B)}{P(A)}

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Late delivery.

Event B: Service 2 was used.

A certain company sends 35% of its overnight mail parcels via express delivery service 1 and the rest by express delivery service 2.

100 - 35 = 65%.

So P(B) = 0.65

Service 2 has a record of 2.0% of packages being delivered late.

This means that P(A|B) = 0.02

Probability of a late delivery.

35% from service 1. Of those, 3% are late.

65% from service 2. Of those, 2% are late.

So

P(A) = 0.35*0.03 + 0.65*0.02 = 0.0235

What is the probability that a late package was delivered by express delivery service 2

P(B|A) = \frac{0.65*0.02}{0.0235} = 0.5532

55.32% probability that a late package was delivered by express delivery service 2

Find the diameter of the base of a right cylinder if the surface area is 128(pi) and the height is 12cm.
Gelneren [198K]
d=2r\\
A=128 \pi \\
A=2 \pi  r^{2} +2 \pi rh \\\\
2 \pi  r^{2} +2 \pi rh = 128 \pi \\
2 r^{2} +2rh = 128\\
2 r^{2}+24r-128=0\\
r^{2}+12r-64=0\\
delta=400\\
r_{1/2} = -16/4 \\
r=4cm\\
d=8cm\\


Radius / diameter as a length cannot be negative, that's why '-16' is wrong.
