<u>Answer:</u>
There is only 1 peak in this distribution.
<u>Step-by-step explanation:</u>
In the distribution of exam scores (graded from 0 100) for 86 students 38 students got an A, 28 students got a B, and 20 students got a C.
a) Since, 38 > 28 > 20 , there is only 1 peak for this distribution.
No intervals are showing, but here is how to solve this equation.
0.35x - 4.8 < 5.2 - 0.9x
Add 4.8 to both sides
0.35x < 10 - 0.9x
add 0.9x to both sides
1.25x < 10
divide both sides by 1.25
x < 8
Interval Notation:
If we graphed this on a number line, x goes toward negative infinity.
Answer: (-∞, 8)
Hope this helps! :)
Answer:
$81
Step-by-step explanation:
Hello, this is the logic:
If $63 ---> 35%
$X -----> 100%
then,
X = [(100)*(63)]/35
X = $18
Then his total money was 63 + 18 = $81
