Joselyn is a manager at a sign-painting company. She has two painters, Allen and Brianne. Allen can complete a large project in

guajiro [1.7K]

Answer:

8.47 Hours

Step-by-step explanation:

Allen can take 16 hours, while

Brianne can take 18 hours;

Therefore, in 1 hour Allen will complete a fraction of 1/16, while

in 1 hour Brianne will complete a fraction of 1/18

When working together, in 1 hour they will complete a fraction of (1/18+1/16)

= 17/144,

Therefore; to complete the whole project working together, they will take;

144/17 = 8.47 hours

James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The

Brrunno [24]

Answer:

The correct option is 4.

Step-by-step explanation:

Given information:

Bring lunch : 46 males, 254 females

Buy lunch : 176 males, 264 females

Total number of peoples is

$46+254+176+264=740$

Total number of males is

$46+176=222$

The probability of male is

$P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3$

Since probability of males is 0.3, therefore options A and C are incorrect.

Total number of persons who buys lunch is

$176+264=440$

The probability of persons who buys lunch is

$P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}$

We need to find the probability of P(male | buys lunch).

According to the conditional probability, we get

$P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}$

P(male | buys lunch) $=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}$

P(male | buys lunch) $=\frac{\frac{176}{740}}{\frac{22}{37}}$

P(male | buys lunch) $=\frac{2}{5}=0.4$

Therefore the correct option is 4.
