Answer:

median = 17.5

Step-by-step explanation:

The median is the middle value of a data set arranged in ascending order. If there is not a middle value then the median is the average value of the numbers either side of the middle.

Data in ascending order is

8, 15, 17, 18, 19, 21

The median is between 17 and 18, hence

median = $\frac{17+18}{2}$ = 17.5

Answer:

Step-by-step explanation:

The median is the value that separates the higher half from the bottom half of the data sample (middle value).

We have

15, 8, 19, 21, 18, 17

Write from the smallest to the largest number

8, 15, 17, 18, 19, 21

We have an even number of numbers. Therefore we calculate the arithmetic mean of the two middle numbers:

8, 15, 17, 18, 19, 21

(17 + 18) : 2 = 35 : 2 = 17.5

Answer:

(b) 360 degrees

Step-by-step explanation:

Required

The central angle

The central $angle$ of a circle is $360^o$ . This implies that the central $angle$ of the pie chart is also $360^o$ , because a pie chart is always in $form$ of a $circle.$

One number is 11 more than 3 times another number. Their sum is 75. Find the smaller number.

Musya8 [376]

X = larger number, y = smaller number

x + y = 75
x = 3y + 11

3y + 11 + y = 75
4y + 11 = 75
4y = 75 - 11
4y = 64
y = 64/4
y = 16 <=== ur smaller number

x = 3y + 11
x = 3(16) + 11
x = 48 + 11
x = 59...ur larger number

A mill processes 27 tons of flour in 3 hours. How many tons of flour can the mill process in 8 hours if the rate of production s

Delvig [45]

There are a few ways you can go about solving this question. One way is to use the given information to find how many tons of flour can be processed in one hour. If 27 tons can be processed in 3 hours, we can do 27 divided by 3 to find that 9 tons of flour can be processed per hour. Then, if we want to see how many tons of flour can be processed in 8 hours, we can multiply 9 tons by 8 hours to get a total of 72 tons of flour.

I hope this helps.
