To find the median, order the numbers in the data set from least to greatest (or greatest to least, either one works) and then find the number in the middle. If there are 2 numbers in the middle, find their mean.

Step 1: Ordering the numbers.
Original: 100, 88, 76, 78, 92, 94, 84, 98, 82, 90
Ordered: 76, 78, 82, 84, 88, 90, 92, 94, 98, 100

Step 2: Find the median (middle number).
The median is the number in the center.
Count in from each side equally to find the middle number.
76, 78, 82, 84, 88, 90, 92, 94, 98, 100
78, 82, 84, 88, 90, 92, 94, 98
82, 84, 88, 90, 92, 94
84, 88, 90, 92
88, 90
88 and 90 are the middle numbers.
Since there are 2 numbers in the middle, we must find their mean.

Step 3: Find the mean of the 2 middle numbers.
Mean is also known as average.
To find this, add up the numbers and then divide by the amount of numbers there are.
In this case, that means adding 88 and 90 then dividing their sum by 2.
This can be represented by the equation (88 + 90) ÷ 2.
88 + 90 = 178
178 ÷ 2 = 89
89 is the final answer, it is the median.

The median of this data set is 89.

Hope this helps!

Answer from: Quest

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 = $6^{2}$

x = 3, y = 216 = $6^{3}$

x = 4, y = 1296 = $6^{4}$

x = 5, y = 7776 = $6^{5}$

so, the geometric series obtained is $6, 6^{2}, 6^{3}, 6^{4}, 6^{5}$ .

thus, the common ratio is given by $\frac{6^{2}}{6}$ = $\frac{36}{6}$ = 6.

hence, the common ratio is 6.

Answer from: Quest

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
