Answer:

1.8 dishes per minute (Sarah)

1.67 dishes per minute (Sunil)

Step-by-step explanation:

We can find the rate by dividing the number of dishes by the number of minutes:

Two stores sell a certain product. Store A has 45% of the sales, 3% of which are of defective items, and store B has 55% of the
Mumz [18]

Answer:

Probability = 0.0355

Step-by-step explanation:

Given

Stot A:

Sales = 45\%

Defective = 3%

Store B

Sales = 55\%

Defective = 4%

Required

Determine the probability a product received is defective.

First, we calculate the probability that the defective product is from store A

Probability = P(Sales) * P(Defective)

P_A = 45\% * 3\%

Convert to decimals

P_A= 0.45 * 0.03

P_A= 0.0135  

Next, we calculate the probability that the defective product is from store B

P_B= 55\% * 4\%

P_B= 0.55 * 0.04

P_B= 0.022

The product may come from either stores.

So, the probability of having a defective product is:

Probability = P_A + P_B

Probability = 0.0135 + 0.022

Probability = 0.0355

Is number 3 is correct and please help with number 4
adoni [48]
No, you forgot to multiply by 5 ml.

250/250 * 5 = 5 ml by mouth three times a day

#4 has to be in correct units. you cannot divide grams by milligrams.

I would change dose to milligrams 0.1g * 1000 = 100 mg dose. Quantity is 1 capsule

100/100 * 1 = 1 pill by mouth twice daily
