The expected value of the inseam length of the jeans is found as
30% of 30+ 25% of 32+ 10% of 34+ 10% of 36 + 10% of 38 + 15% of 40
=
=
Hence, the third option 33.8 is the correct expected value.
Can someone please answer this for me ? thanks

Answer:
x=-4.5
Step-by-step explanation:
In the given triangle, Two sides are divided into equal part.
It means D and E is mid point of AB and AC.
Mid-point theorem: The line joining the mid points of sides of a triangle then line (DE) parallel to BC and DE is half of BC.
In the given figure, (Attachment)
DE = 3x+4
BC = 4x-1
[mid-point theorem]
Hence, The value of x is -4.5

The last one was kind of tricky. But, as I saw this attachment, I noticed on how the rectangle was actually 3/4 on the base and for the height, it was 1/2. So by doing this,we need to find the area, and we would multiply these both. 1/2 x 3/4 = 3/8 but by looking at your options, those are not simplified so . . .your answer would be 6/16 because 3x2=6 & 8x2=16.

I really hope this can help you Amanda.
