In a survey, 17 high school graduates and 16 non-graduates were asked a qiestion.

5 people are sharing 10 pies equally. How much pie will each person get?

s344n2d4d5 [400]

Hey there!

To find out the answer you have to DIVIDE the number of pies (which is 10) from the number of people (5) because if we do any other operations your result would be way too big or too small to make it equal amounts for each person.

EQUATION:

≈ 10 ÷ 5

CONVERSION of EQUATION:

≈ 10/5

ANOTHER CONVERSION of EQUATION:

≈ 10 ÷ 5 / 5 ÷ 5

SOLVING:

≈ 2/1

SIMPLIFICATION:

≈ 2 ÷ 1

YOUR RESULT: 2

Therefore, your answer is: 2

Good luck on your assignment and enjoy your day!

Each one of four people will request either Coke D Let X denote the number that request Coke, where the remainder request Sprite

34kurt

Answer:

a) E(x)=2.5 V(x)=1.59

b) E(R)=17 V(R)=6.36

c) The probability that, when the four make their orders, everyone gets what they ordered is P=0.66.

Step-by-step explanation:

a) The mean E(x) can be calculated as:

$E(x)=\sum^4_{i=0} p_ix_i\\\\E(x)=0.09*0+0.15*1+0.18*2+0.33*3+0.25*4\\\\E(x)=0.00+0.15+0.36+0.99+1.00\\\\E(x)=2.5$

The variance V(x) can be calculated as:

$V(x)=\sum^4_{i=0} p_i(x_i-\bar x)^2\\\\V(x)=0.09(0-2.5)^2+0.15(1-2.5)^2+0.18(2-2.5)^2+0.33(3-2.5)^2+0.25(3-2.5)^2\\\\V(x)=0.09*6.25+0.15*2.25+0.18*0.25+0.33*0.25+0.25*2.25\\\\V(x)=0.5625+0.3375+0.045+0.0825+0.5625\\\\V(x)=1.59$

b) The revenue can be expressed as:

$R=5*x+3*(4-x)$

Then, the expected value of R canbe expressed in function of x:

$E(R)=E(5x+3(4-x))=5E(x)+3(4-E(x))\\\\E(R)=5*2.5+3(4-2.5)=12.5+4.5=17$

The expected revenue is $17.

The variance of R is

$V(R)=V(5*x+3(4-x))=V(5x+12-3x)=V(2x+12)\\\\V(R)=V(2x)+V(12)=2^2V(x)+0=4*1.59\\\\V(R)=6.36$

c) In the case there are only 3 Cokes and 3 Sprites available, the only orders that can not be fullfilled are when X=0 (they order 4 Sprites) and X=4 (they order 4 Cokes).

The probability of these events is:

$P(x=0,x=4)=P(x=0)+P(x=4)=0.09+0.25=0.34$

So, the probability of everyoned getting what they ordered is:

$P=1-P(x=0,x=4)=1-0.34=0.66$

The probability that, when the four make their orders, everyone gets what they ordered is P=0.66.

A construction company is repaving a damaged road. So far, they have repaved a total of 97,338 inches of the road. Today, they r

borishaifa [10]

68,246 inches of road had been repaved before today.

Step-by-step explanation:

Given,

Length of road repaved so far = 97338 inches

Length repaved today = 29092 inches

Length repaved before today = Total length repaved - Length repaved today

Length repaved before today = 97338 - 29092

Length repaved before today = 68246 inches

68,246 inches of road had been repaved before today.
