Answer:
The range in a data set is the difference between the highest and lowest values in a group of numbers. In order to find the range you have to order the data from least to greatest. Then you have to subtract the lowest number from the highest number. For example, the numbers are 21, 32, 45, & 80. You have to subtract 80-21 = 59. So, <u>in this case</u> 59 would be your range.

Answer:
24 males
7 females
Step-by-step explanation:
<u>Step 1: Write the data</u>
Total number of students: 31
Number of males: x
Number of females: x - 17
<u>Step 2: Form an equation</u>
males + females = total students
x + x - 17 = 31
2x = 48
x = 24
There were 24 males
<u>Step 3: Find the number of females</u>
Number of females = x - 17
Number of females = 24 - 17
Number of females = 7
Therefore, there were 24 males and 7 females in the class.

X=lebgth
y=width.
I suggest this system of equations:
x=2y
(x+4)(y+4) - xy=88
we can solve this system by substitution method.
(2y+4)(y+4)-2y(y)=88
2y²+8y+4y+16-2y²=88
12y=88-16
12y=72
y=72/12
y=6
x=2y
x=2(6)=12
Answer: the dimensions of the original rectangle are:
