7 0

Answer:

a) 1/4

b) 1/6

c) 1/12

Step-by-step explanation:

Let S be the sample space.

S={H1,H2,H3,H4,H5,H6,T1,T2,T3,T4,T5,T6}

n(s) =12

<em><u>Events </u></em>

A: coin with head and die with prime number .

B:coin with head and die with composite number.

C:coin with tail and die with even prime number.

a) A={H2,H3,H5}

n(A) = 3

P(A) =n(A)/n(S)

=3/12

= 1/4

b) B={H4,H6}

n(B)= 2

P(B) = n(B)/n(S)

= 2/12

= 1/6

c) C ={T2}

n(C) = 1

P(C) = n(C)/n(S)

= 1/12

At a telethon, a volunteer can take 48 calls over a 4-hour shift. At this rate, how many calls can 12 volunteers take in a 4-hou
stellarik [79]
1 volunteer - 4 h - 48 calls
12 volunteers - 4 h - x calls

The time is the same, so it's irrelevant.
1 volunteer - 48 calls
12 volunteers - x calls

x=12*48=576

So it's 576 hours.

Joanne has a cylindrical, above ground pool. the depth (height) of the pool is 1/2 of its radius, and the volume is 1570 cubic f
Svetradugi [14.3K]

We know that Volume of Cylinder is given by : πr²h

Where : 'r' is the Radius of the Cylinder

             'h' is the Height or Depth of the Cylinder

Given : The Height of the Pool is Half of its Radius

⇒ Height of the Pool =  \frac{r}{2}

Given : The Volume of the Pool = 1570 feet³

⇒ πr²h = 1570

⇒ \pi (r^2)(\frac{r}{2}) = 1570

⇒ (\frac{22}{7})(\frac{r^3}{2}) = 1570

⇒ \frac{22r^3}{14} = 1570

⇒ r^3 = \frac{1570\times 14}{22} = 999

⇒ r = \sqrt[3]{999} = 10\;(approx)

As : Area of the Bottom of the Pool is Circular

We know that Area of Circle is given by : πr²

⇒ Area of the Bottom Floor = π × 10² = 314.15 feet²
