Mean =

Median =

Mode =

Answers

Answer:

Mean: 83.571428571429

Median: 85

Mode: 70

Step-by-step explanation:

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

Answer:

Median 85

Mode 70

Mean 83.571 rounded = 83.6

I need the equation for the answer 4a = 32

Answers

If you’re asking for what a would equal to, it is 8.

To find it, you just divide 32 by 4.

Answer:

a = 8

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.

Divide 4 from both sides of the equation:

(4a)/4 = (32)/4

a = 32/4

a = 8

8 is your answer for a.

Part A: x = 5t + 5

20 = 5t +5

Part B: x = 5t + 5

x = 5(7) + 5

x = 35 +5

x = 40

paul got 72 marks in a maths test. 72 marks is 60% of the total number of marks. work out the total number of marks in the test ​

Answers

Answer:

115.2 total marks.

Step-by-step explanation:

If 72 is only 60% of the total marks, then to find the total number of marks we will need to multiply 72 by 60% to find the remaining marks, then add that back to 72.

72 × 0.6 = 43.2 remaining marks.

72 + 43.2 = 115.2 total marks.

The total number of marks in the test ​ is 115.2 total marks.
