Answer:

EF=8 FG=15

Step-by-step explanation:

EF+FG=EG

2x-12 + 3x-15 =23

5x-27 =23

5x=50

x=10

From earlier studies, it is believed that the percentage of students favoring a four-day school week during May and June of ever

Oksi-84 [34.3K]

Answer:

The minimum sample size 'n' = 862.538

Step-by-step explanation:

Step(i):-

Given the percentage of students favoring a four-day school week during May and June of every school year is approximately 85%

Given the Proportion of students favoring a four-day school week during May and June of every school year

p = 85% = 0.85

q = 1-p = 1-0.85 = 0.15

Given Margin of error = 2 % or 0.02

Level of significance = 0.90 or 0.10

The critical value Z₀.₁₀ = 1.645

Step(ii):-

The Margin of error is determined by

$M.E = Z_{0.10} \sqrt{\frac{p(1-p)}{n} }$

$0.02=1.645 X \sqrt{\frac{0.85(0.15)}{n} }$

Cross Multiplication, we get

$\sqrt{n} =1.645 X {\frac{\sqrt{0.125} )}{0.02} }$

√n = 29.369

squaring on both sides, we get

n = 862.538

Final answer:-

Sample size 'n' = 862.538

Prizes and the chances of winning in a sweepstakes are given in the table below.

The expected value of the discrete distribution, for each case, is given as follows:

a) Amount won by one entry: $0.075.

b) If the cost is the cost of a postage stamp: -$0.525.

<h3>How to obtain the expected value of a discrete distribution?</h3>

The expected value of a discrete distribution is obtained with the sum of each outcome multiplied by it's probabillity.

In this problem, the distribution for the prizes is given as follows:

P(X = 10,000,000) = 1/300,000,000.

P(X = 350,000) = 1/150,000,000.

P(X = 50,000) = 1/10,000,000.

P(X = 20,000) = 1/1,000,000.

P(X = 400) = 1/200,000.

P(X = 75) = 1/6,000.

Hence the expected value for the prizes is:

E(X) = 10,000,000 x 1/300,000,000 + 350,000 x 1/150,000,000 + 50,000 x 1/10,000,000 + 20,000 x 1/1,000,000 + 400 x 1/200,000 + 75 x 1/6,000 = $0.075.

The cost of a postage stamp is of $0.6, hence the expected value considering this cost would be of:

0.075 - 0.6 = -$0.525.
