Let's define the following variable:
 t = total time it takes to assemble a shelving unit together.
 We then have the following equation:
 1/5 + 1/3 = 1 / t
 Solving the equation we have:
 3t + 5t = 15
 8t = 15
 t = 1,875 hours
 Answer:
 
the time it takes for worker A and worker B to assemble a shelving unit together is:
 t = 1,875 hours

Grandma is trying out a new recipe for raisin bread. Each batch of bread dough makes three loaves, and each loaf contains 15 sli
Tom [10]

Answer:

0.108

Step-by-step explanation:

Using the poisson probability process :

Where :

P(x =x) = (e^-λ * λ^x) ÷ x!

Given that :

Each batch of bread = 3 loaves

Each loaf = 15 slices

Total slice per batch = 15 * 3 = 45 slices

Number of raising added = 100

Average number of raisin per slice, λ = 100/45 = 20/9

Hence,

Probability that a randomly chosen slice has no raising :

P(x = 0) = (e^-λ * λ^x) ÷ x!

P(x = 0) = (e^-(100/45) * (100/45)^0) ÷ 0!

P(x = 0) = (0.1083680 * 1) / 1

P(x = 0) = 0.108
