A basketball player makes 80% of her free throws. The random numbers below represent 20 trials for

Taya2010 [7]

Answer:

0.6

Step-by-step explanation:

The numbers 0 to 7 represent a made free throw
The numbers 8 to 9 represent a missed free throw.

Given the simulation data

(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)

(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)

A pair that contains only numbers between 0 and 7 shows the player makes both throws.

These pairs are:

(4,0) (2,7) (2,0) (5,4) (0,4) (6,5) (4,4) (1,7) (0,4) (1,7) (3,5) (0,3)

There are a total of 12 cases where the player makes both throws.

Therefore:

P(Player makes both throws)=12/20=0.6

The volume of a storage tank is 1695.6 m3. The radius is 6m. How tall is the storage<br> tank?

Andreas93 [3]

Answer:

the storage tank is a cylinder.

The formule to calculate the volume is:

$v =\pi{r}^{2} \times h$

$h = v \div \pi {r}^{2}$

$h = 1695.6 \div 36 \times \pi = 14.992$

A hotel is in the shape of a cylinder, with a circular foundation. the circumference of the foundation is 4 times the radius,

Marat540 [252]

Let
C-------> the length of a circumference

C=2*pi*r-----> equation 1

we know that
in this problem-----> <span>the circumference of the foundation is 4 times the radius, increased by 114 ft
</span>so
C=4*r+114------> equation 2
(1)=(2)
2*pi*r=4*r+114------> 2*pi*r-4*r=114-----> r*[2*pi-4]=114---> r=114/[2*pi-4]
r=114/[2*pi-4]-----> 50 ft

the answer is
r=50 ft
