Answer:

20% probability that the next customer will pay with cash

Step-by-step explanation:

A probability, as a decimal, is the number of desired outcomes divided by the number of total outcomes.

To find as percent, we multiply by 100.

In this question:

Total of 54+63+153 = 270 customers.

Of those, 54 paid with cash.

Based on the number of customers from last week, what is the probability as a percent that the next customer will pay with cash?

54/270 = 0.2

0.2*100 = 20%

20% probability that the next customer will pay with cash

Kobotan [32]

Answer:

Sampson gains 3.967 kilograms from November to February.

Step-by-step explanation:

Given:

Actual Weight on November 15 = 2.49 kg

On December 15, he weighed 1020 grams more

Since 1000 grams = 1 kg

Weight on December 15 = 1020 grams = 1.2 kg

Hence Weight gained from November 15 to December 15 = 1.2 kg

On January 15, he had gained another 2200 grams

Weight on January 15 = 2200 grams = 2.2 kg

Hence Weight gained from December 15 to January 15 = 2.2 kg

On February 15, he had only gained 0.567 kilograms.

Weight on February 15 = 0.567 kg

Hence Weight gained from January 15 to February 15 = 2.2 kg

Total weight gained from November to February = Weight gained from November 15 to December 15 + Weight gained from December 15 to January 15 + Weight gained from January 15 to February 15

Total weight gained from November to February = $1.2+2.2+0.567 = 3.967 \ kg$

Hence Sampson gained total weight of 3.967 kg from November to February.
