1/3 of 81 = 81 • 1/3 = 81/3 = 27
3x + 1 = y
x: 1 | 2 | 3 |
------|---|--- |----------------
y: 4 | 7 | 10|
so make points at (1,4) (2,7) and (3,10), and connect them to get the line
4x + 1
x: 1 | 2 | 3
----------------
y: 5 | 9 | 13
Make points at (1,5) (2,9) and (3,13)
IF they do not intersect yet, continue making points until they intersect. Make note of the point in which they intersect, and that is your answer
hope this helps
The range for boys is 60 as for girls the range is 80. The median for boys is 90 and for girl 110.
Answer: $574
Step-by-step explanation:
First we need to calculate the price of the snowboard before the addition of the tax. This will be represented by x. Therefore,
6% of x = $32.50
0.06 × x = $32.50
0.06x = $32.50
x = $32.50 / 0.06
x = $541.67
Therefore, the total cost including the sales tax will be:
= $541.67 + $32.50
= $574.17
= $574
Answer:
Mean: 58
Median: 58
Step-by-step explanation:
- The mean is a <u>type of </u><u>average</u>. <u>It is the </u><u>sum (total)</u><u> of all the values in a set of data</u>, such as numbers or measurements, divided by the number of values on the list. <u>To find the mean, add up all the values in the set. Then divide the sum by how many values there are.</u>
- <u>The median is the </u><u>middle </u><u>number</u>; <em>found by ordering all data points and picking out the one in the middle</em>
FINDING THE MEAN:
57 + 54 + 59 + 57 + 61 + 58 + 60 = 406
406 ÷ 7 = 58
FINDING THE MEAN:
Arrange the numbers from <u>smallest to greatest:</u>
54, 57, 57, 58, 59, 60, 61
Find the <u>median</u> number:
54, 57, 57, <em><u>58</u></em>, 59, 60, 61
The median is: <u><em>58</em></u>
