Based on the emperical rule
the distribution will be as follows
btwn 80 n 85 on the test - 34%
btwn 80 n 95 on the test - 82%
below 85 on the test - 50%
<span>above an 80 on the test - 84%</span>
Answer:
s = 3
Step-by-step explanation:
we know the rectangles are similar
2 × __ = 16
s × __ = 24
so,
16÷2 = 8
2 × 8 =16
s × 8 =24
then,
24 ÷ 8 = s
3 = s
2 × 8 = 16
3 × 8 =24

Answer:
solve it like there is an equals sign instead of less than
Step-by-step explanation:
get r on the same side
35r+35r<40
Answer:

Step-by-step explanation:
We know that we are dealing with parallel lines, as there are double headed arrows on each of the lines, pointing in the same direction.
This means we can use corresponding / alternate angle laws.
We know that the angles on a straight line add up to
, so we can solve for the angle just above the
to try and see if that will help us.
(Our angle, added to another angle we don't know yet is 180)
Solve for 

We can now apply the corresponding angle law, (as we have an 'F' shape), to determine that:
