About 48 students are girls
Step - By - Step Explanation:
63 / 4 = 15.75
15.75 x 3 = 47.25
Because you can’t have 0.25 (1/4) of a person, you round to the next number.
Hope this helps!
Answer:
When x = -1/4 and when x = -15/4
Step-by-step explanation:
The x intercept will be when f(x)=0, so
0 = 4|x+2| -7
7 = 4|x+2|
|x+2|=7/4 here you have to cases
case 1
x+2=7/4
x=7/4-2
x=-1/4 = -0.25
case 2
x+2 = -7/4
x = -2-7/4
x = -15/4 = -3.75
Answer:
Median = 47
Step-by-step explanation:
Median is the "middle" number when arranged from smallest to largest.
Arranging in ascending order:
32, 45, 47, 63, 72
We see that the 3rd number in the list is the "middle" number.
3rd number is 47
Hence, median is 47
Answer:
width = 7 cm
Step-by-step explanation:
So, to find the perimeter you multiply the width by 2, multiply the length by 2, then add them together.
P = 2L + 2W
But, we already know the perimeter and length, so we need to find the width.
78 = 2(32) + 2W
78 = 64 + 2W
-64 -64
14 = 2W
/2 /2
7 = W
So, to check your answer, plug in the width (that you just found), and the length to see if you get 78, the perimeter.
P = 2L + 2W
P = 2(32) + 2(7)
P = 64 + 14
P = 78
So, yes, the width =7
