Answer:

Cost of storybook is $16

Step-by-step explanation:

Let's assume that the Cost of storybook= ‘x’

If the cost of the cookbook is 3 times the cost of storybook then the cost of the cookbook will be ‘3x’

The cost of 1 cookbook and 4 storybooks = $112

The cost of cookbook and storybook can be calculated by the equation:

3x+4x=112

7x=112

Divide both sides by 7 to isolate x:  

7x/7=112/7

x=16

Therefore, the cost of storybook is $16

Suppose x follows a continuous uniform distribution from 1 to 5. determine the conditional probability p(x >2.5 | x ≤ 4).
Rainbow [258]
Because the random variable x follows a continuous uniform distribution from x=1 to x=5, therefore
p(x) = 1/4,  x=[1, 5]
The value of p(x) ensures that the total area under the curve = 1.

The conditional probability p(x > 2.5 | x ≤ 4) is the shaded portion of the curve. Its value is
p(x > 2.5 | x ≤4) = (1/4)*(4 - 2.5) = 0.375

Answer: 0.375
