Benjamin believes that 1/2 % is equivalent to 50%. Is he correct? Why or why not? Please explain.

Answers

Answer:

Benjamin is correct.

Step-by-step explanation:

1/2 converted to a decimal (1 divided by 2) is 0.50, which when converted to a percentage is 50%.

1 ÷ 2 = 0.5

.5 × 100 = 50 ⇒ 50%

So, 1/2% = 50%

Also, 1/2 is 50%. So, that should automatically prove that he is correct.

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.

Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.
Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.
Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?

Answers

Answer:

Didn't study: 76%

Mean absolute deviation: 11.2

Step-by-step explanation:

To find the mean, add all the scores from the people who didn't study and divide them by 12 (the total number of students who didn't study). You will get 76%To find the MAD, use the formula for MADTo answer the third, line them up in order. 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91. MAD is the average difference between the numbers. So, to find this answer, subtract two of the MAD's from the mean of 76%. 76-22.4 = 53.6. So, only one is more than two MAD's away from the mean of 76%.
92.5 is the answer for part 1

4 chef require 10 minutes to prepare 20 desserts. At this rate how many chefs are needed to prepare 75 desserts in 15 minutes?

PLS HELP! PLS TELL ME HOW YOU GOT THE ANSWER. THIS IS FOR MY COUSIN. SHE NEEDS HELP.

Answers

So right now, you need 4 chefs to prepare 20 deserts in 10 minutes (so the rate is one chef can make a dessert in 2 minutes) so if we think about this 7.5 desserts can be made by one chef in 15 minutes, BUT no one wants 1/2 of a dessert, so we must round this down to 7, and now we divide 75 by 7 to get 10.7, but we don’t want 0.7 of a cheap, so we round up to get 11 chefs can make 75 desserts in 15 minutes

The number of chefs that are needed to prepare 75 desserts in 15 minutes is; 10 chefs

According to the question;

4 chefs require 10minutes to prepare 20 desserts

For the scenario above; This means;

4 chefs are able to prepare 2 desserts/minute.

The question requires that we determine how many chefs are needed to prepare 75 desserts in 15 minutes.

In essence;

x chefs are able to prepare (75/15) = 5 desserts/minute.

Therefore;

x = (5 × 4)/2

x = 10 chefs

Ultimately, 10 chefs are needed to prepare 75 desserts in 15 minutes.
