Answers

Answer:

8 units

Step-by-step explanation:

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: 88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84

Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Calculate the range and interquartile range for each set of data.
Using complete sentences, compare the data sets based on your results in part A.

Answers

You add all of the numbers and the divid by the amount of number for example 88+ ......... = 1667 and then you divid by 18 because that is how many numbers there are equaling 92.61% so 92.61% STUDIED

A family spent $65 on dinner and left a 20% tip. What was the total cost of their meal?

A. $85

B. $78

C. $67

D. $13

Answers

Answer: B, $78

Step-by-step explanation:

If the tip is 20% of the dinner cost, then we have to first find what is 20% of 65.

20% x 65 = 13. So the tip for the dinner is 13 dollars.

Now we have to add it to the original dinner cost.

65 + 13 = 78.

Therefore, the total cost of their meal is 78 dollars. So the answer is B, $78!

Answer: A

Step-by-step explanation:

the total cost of their meal it usally means how much in total so we add 65+20 = 85

i think its 2 because 1 is an odd number and it goes 1,1 ( two odd numbers) then __ 3,5 ( two more odd numbers then 8,13,21( even number then two more odd numbers) the 34( even number). i'm thinking the pattern is odd, odd, even, odd, odd, even, odd odd, even.

it’s 2 because each number adds the number before it to get the next one
