Answer:
84
Step-by-step explanation:
Answer:
[5, oo)
Step-by-step explanation:
Add 6x+16 to both sides:
20 ≤ 4x
5 ≤ x . . . . . . divide by 4
The solution interval is [5, oo).
Step-by-step explanation:
6) x+y=60
x/y=7/5------(2)
x=(7/5)y
(7/5)y + y =60
(12/5)y=60
y=60(5/12)
y= 25
x=(7/5)y=(7/5)×25 =35
the two numbers are 35 and 25
7)distance walked by A = 4t
distance walked by B = 5t
4t+5t=27
9t=27
t=27/9=3hours
The Median is 11, and it is shown by the line on the middle of the rectangle.
The range is 12, and you can find it by subtracting the highest data point (17) by the lowest data point (5).
The 25th percentile is 9, and it could be found by looking at the first line in the rectangle.
The 75th percentile is 14, and it could bee found by looking at the last line in the rectangle.
The inter-quartile range is 5, and it can be found by subtracting the upper quartile, or the 75th percentile (14) by the lower quartile, or the 25th percentile (9). 14-9=5
Hopefully this helps.
