Answer:99.7%

Step-by-step explanation:

The empirical rule states that for a normal distribution, almost all of the

data will fall within three standard deviations of the mean. It states that

1) 68% of the data falls within one standard deviation of the mean.

2) 95% of the data falls within two standard deviations of the mean.

3) 99.7% of the data falls within three standard deviations of the mean.

From the information given, the mean is $70 and the standard deviation is $9. We want to determine the percentage of her phone bill that is between 43% and 97%

Looking at ±3 standard deviations of the mean, it becomes

70 ± 3×9 = 70 ± 27

The value is between 70 - 27 = 43 and 70 + 27 = 97

Therefore, the percentage of her phone bills that is between 43% and 97% is 99.7%

Chiletso just got a new cylindrical fish tank, which he plans to stock with a variety of african cichlids.
Anit [1.1K]

The maximum number of African cichlids which can put by Chiletso  in this cylindrical fish tank is 19.

<h3>What is of volume of cylinder?</h3>

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

The volume of the cylinder can be given as,

V=(πd^2h)4

Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.

The height of tank is 30 inches and the length of the diameter of the base is 27.5 inches. Thus, the volume of it is,

V=[π(27.5)²(30)] /4

V=17818.72 cubic inches.

One us gallon is equal to approximately 231 cubic inches. Thus, the volume in gallon is,

V=17818.72/231

V=77.12 gallons.

A good rule of thumb is to have about 3 inches of fish per 2 gallons of water. The number of 6 inches cichlids the can put in 77.12 gallons tank is,

V=(77.12 x 3)/(6 x 2)

V=19.28

Thus, the maximum number of African cichlids which can put by Chiletso  in this cylindrical fish tank is 19.

A runner finished a total of 1,500 kilometers in races before retiring . She finished thirty-two 15-kilometer races . The rest o
mihalych1998 [28]

102 of runner's races were 10-kilometer races.

Step-by-step explanation:

Given,

Total kilometers finished = 1500 km

Number of 15 km races = 32

Number of 10 km races = x

Therefore;

15*32+10x=1500

480+10x=1500\\10x=1500-480\\10x=1020

Dividing both sides by 10

\frac{10x}{10}=\frac{1020}{10}\\x=102

102 of runner's races were 10-kilometer races.
