Georgia [21]

Answer: \dfrac{15}{32}

Step-by-step explanation:

Given : The number of cherry lollipop = 5

The total number of lollipop = 8

the number of lollipops other than grape =6

The probability of selecting a cherry lollipop is given by :_

\text{P(Cherry)}=\dfrac{5}{8}

The probability of selecting a lollipop other than grape is given by :_

\text{P(Other than grape)}=\dfrac{6}{8}

Since, there is replacement , then the events are independent of each other.

Now, the probability that Julie will select a cherry lollipop and then a lollipop other than grape is given by :-

\text{P(Cherry and other than grape)}=\dfrac{5}{8}\times\dfrac{6}{8}=\dfrac{15}{32}

Hence, the required probability =\dfrac{15}{32}

Tatiana [17]

Answer:

\$226.08

Step-by-step explanation:

step 1

Find the volume of the tank (cylinder)

The volume of cylinder is given by the formula

V=\pi r^{2}h

we have

r=3\ ft\\h=2\ ft\\\pi=3.14

substitute

V=(3.14)(3)^{2}(2)

V=56.52\ ft^3

step 2

Find the cost of rent one tank

Multiply the volume of one tank by the unit rate of $4 per cubic foot

56.52(4)=\$226.08
