The outcomes of an experiment and the probability of each outcome are given in the table below. Compute the expectation for this experiment.

Answers

Answer 1

Answer:

Step-by-step explanation:

sum the outcome times the probabilities

5*.5+6*.12+7*.2+8*.08+9*.06+10*.04= 6.2

Answer 2

The expectation of the experiment is the mean or the average value of the experiment

The expectation of the experiment is 6.2

The expectation is calculated using the following formula of expected value

[tex]E(x) = \sum Outcome \times Probability[/tex]

Rewrite the formula properly, as:

[tex]E(x) = \sum x \times p(x)[/tex]

So, we have:

[tex]E(x) = 5 \times 0.5 + 6 \times 0.12 + 7 \times 0.2 + 8 \times 0.08 + 9 \times 0.06 + 10 \times 0.04[/tex]

Evaluate the above equation

[tex]E(x) = 6.2[/tex]

Hence, the expectation of the experiment is 6.2

Step-by-step explanation:

Equal all the zeros to x then move them over.

x-7,x+3,x+0,x+2

Then multiply each factor

The answer is f(x) = 5 - 2x

Function form means just replace y with f(x).

Subtract 8x
4y = 20 - 8x

Divide both sides by 4

5. for Store A- 4 pairs of jeans is $120 so if you divide that which is 120/4 it gives you 30 so it would mean your paying $30 for each pair of jeans

for Store B- 2 pairs of jeans will cost you $100 so if you add 50+50 it gives you a hundred so it means your paying $50 for each pair of jeans

for Store C- 3 pairs of jeans is $99 so if you divide 99/3 its 33 which means you would be paying $33 dollars for each pair of jeans

so out of all of then Store A gives you the best deal.
