= -3/2 * -5 1/4
convert 5 1/4 to improper fraction

= -3/2 * -21/4
multiply numerators; multiply denominators

= (-3*-21)/(2*4)
multiply in parentheses

= 63/8
convert back to mixed number

= 7 7/8

ANSWER: Since the exact answer is the mixed number 7 7/8, a reasonable estimate is 8.

Hope this helps! :)

Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews

Andrej [43]

Answer: The required probability is 0.615.

Step-by-step explanation:

Let A be the event that a product receives good reviews.

Let E₁ be the event that the product is highly successful.

Let E₂ be the event that the product is moderately successful.

Let E₃ be the event that the product is poor.

$P(E_1)=0.40\\\\P(E_2)=0.35\\\\P(E_3)=0.25\\\\P(A|E_1)=0.95\\\\P(A|E_2)=0.60\\\\P(A|E_3)=0.10$

(a) What is the probability that a product attains a good review.

So, it becomes,

$P(A)=P(E_1)P(A|E_1)+P(E_2)P(A|E_2)+P(E_3)P(A|E_3)\\\\P(A)=0.4\times 0.95+0.0.35\times 0.6+0.25\times 0.1\\\\P(A)=0.615$

Hence, the required probability is 0.615.
