Answer: Hence, Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Probability of successful outcome = 0.7

Probability of unsuccessful outcome = 0.3

Amount he get for successful outcome = $900

Amount he lost for unsuccessful outcome = -$1800

We need to find the expected value of return when there is successful outcome:

P(Success)× Amount for successful

0.7\times \$900\\\\=\$630

Hence, Option 'D' is correct.

A movie rental company offers two plans for its customers. The digital movie plan costs $3 per movie and no monthly fee. The DVD
Karo-lina-s [1.5K]
Make an algebraic expression for each plan.
For an instance, x represents the number of movies, and y represents the number of months
⇒ The expression for the digital movie plan is 3x
⇒ The expression for the DVD plan is 10y + 0.5x

A person rents movies in a month (that means the value of y equals 1), the expression of the DVD plan would be 10(1) + 0.5x = 10 + 0.5x

Find the value of x when the cost of both plan are the same
The two options will cost the same when the expression for digital movie is equal to the expression for DVD
the digital movie plan = the DVD plan
3x = 10 + 0.5x

Solve for x
3x - 0.5x = 10
2.5x = 10
x = 10/2.5
x = 4

The two options will cost the same, if the person rents 4 movies

A = 12, b = ?, c = 15<br> a = ?, b = 7, c = 25<br> a = 8, b = 15, c = ?<br> a = 24, b = ?, c = 26
Inga [223]
1: b=9
2: a= 24
3: c=17
4: b=10

Use a^2 + b^2 = c^2 to answer.
1: 12^2 (144) + b = 15^2 (225)
225-144 = 81
Square root 81 = 9
2: a + 49 = 625
625-49=576
Square root 576 = 24
3: 64 + 225 = 289
Square root 289 = 17
4: 576 + b = 676
676-576 = 100
Square root 100 = 10
