Past experience shows that every new book by a certain publisher captures randomly between 3 and 11% of the market. What is the probability that the next book by this publisher captures at most 6.15% of the market?

0.39375 = 39.375% probability that the next book by this publisher captures at most 6.15% of the market

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

The probability of finding a value between c and d is:

The probability of finding a value above x is:

Randomly between 3 and 11% of the market.

This means that

What is the probability that the next book by this publisher captures at most 6.15% of the market?

0.39375 = 39.375% probability that the next book by this publisher captures at most 6.15% of the market

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
