Answer : option A
To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile
Inter quartile range is the middle 50% of the given range of scores.
The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%
From the diagram , we can see that
Upper quartile = 89
lower quartile = 65
So range is 65% to 89%
Answer:
y=2/3x−4
Step-by-step explanation:
Answer with Step-by-step explanation:
The given figure is a cuboid.
We know that surface area(S) of cuboid is given by:
S=2(lb+bh+hl)
Where l is the length, b is the breath and h is the height
Here, l=12 mm
b=6 mm
and h=(7+2) mm=9 mm
Surface Area= 2(12×6+6×9+9×12)
=2(72+54+108)
= 2×234
= 468 mm²
Hence, Correct option is:
C. 468 mm squared
Yes it is, the two lines intersect that point.
6 less than the product of 7 and this number is 85.
6 less than (the product of (7 and this number)) is 85.
6 less than (the product of 7 and x) = 85
6 less than (7 * x) = 85
(7 * x) - 6 = 85
Now you solve! Make sure that whatever you do to one side you also do to the other:
7x - 6 = 85
7x - 6 + 6 = 85 + 6
7x = 91
7x /7 = 91 /7
x = 13
Hope this helps! :)
