I think it’s 8/55=4/x
So it’s 8x=4(55)
8x=220
x=220/8
x=27.5
Answer:
B
Step-by-step explanation:
The worker's expected weekly bonus is $30.0
<h3>How to determine the worker's expected weekly bonus?</h3>
The amounts and the probabilities are given as:
x $10 $50
P(x) 0.75 0.25
The worker's expected weekly bonus is calculated as:

So, we have:
E(x) = $10 * 0.75 + $50 * 0.25
Evaluate the product
E(x) = $17.5 + $12.5
Evaluate the sum
E(x) = $30.0
Hence, the worker's expected weekly bonus is $30.0

Ooh I loved this stuff but I kinda forgot how to do it but I know you are supposed to multiply 2 times pi times times radius so then 2 times 3.14 times 2.6 = ... and pi times 22 =...
56/70
To simplify this, find the highest factor they have in common, which is 14 in this case.
Then divide 56 and 70 by 14.
(56/14) / (70/14)
4/5
Hope this helps :)
