Answer:
the second one
Step-by-step explanation:
Hello, and thank you for posting your question here on brainly.
When you're dividing two fractions, there's a simple rule to follow.
You flip the second fraction, (aka reciprocal) and then multiply.
2/3 ÷ 1/4 = 2/3 * 4/1
You multiply across from the top and bottom.
2/3 * 4/1 = 8/3
8/3 = 2 2/3
Your final answer is C.
Hope this helps! ☺♥
I don't know sorry anjsjdjd
calculate the percentage increase,work out the difference (increase) between the two numbers you are comparing. Then divide the increase by the original number and multiply the answer by 100.
520-500 = 20
20÷500 =.04
.04 ×100= 4%
Answer:
A. The E(Y) is 0.80
B. The expected amount of the surcharges is $165
Step-by-step explanation:
A. In order to calculate the E(Y), we would have to calculate the following formula:
E(Y)=∑yp(y)
E(Y)=(0*0.5)+(1*0.25)+(2*0.20)+(3*0.05)
E(Y)=0+0.25+0.40+0.15
E(Y)=0.80
B. In order to calculate the expected amount of the surcharges we would have to calculate the following formula:
E($110Y∧2)=110E(Y∧2)
=110∑y∧2p(y)
=110((0∧2*0.5)+(1∧2*0.25)+(2∧2*0.20)+(3∧2*0.05))
110(0+0.25+0.80+0.45)
=$165
