Answer: 9/8

Step-by-step explanation: In this problem, we are asked to find the reciprocal of the fraction 8/9. When we are asked find the reciprocal of a fraction, we simply flip the fraction so the denominator is in the position of the numerator and the numerator is in the position of the denominator.

So if we flip 8/9, we get the improper fraction 9/8.

andrey2020 [161]

Answer:

10.50 acres per hour or 1.75 per 10 minutes(1/6 of an hour)

Step-by-step explanation:

5/6 of an hour is 50 minutes

1/6 of an hour is 10 minutes

8 3/4 is equal to 8.75

8.75/5 is equal to 1.75 which means she harvests 1.75 acres per hour

1.75 x 6(hour) is equal to 10.50 acres total in one hour

your friend says that the volume of a sphere with a radius r is four times the volume of a cone with radius r. when is this true

Ierofanga [76]

Volume of a sphere is given by the formula: $V_{\circ}=\frac43\pi r^3$

If we pull the 4 out front we have, $V_{\circ}=4\left(\frac13\pi r^3\right)$ .

Volume of a cone is given by the formula: $V_{\triangle}=\frac{1}{3}\pi r^2\cdot h$

Notice that if the height of the cone is equal to the radius, $V_{\triangle}=\frac13\pi r^2\cdot r$

then it's exactly what we see in our volume formula without the 4!

About 7% of the population has a particular genetic mutation. 400 people are randomly selected. Find the standard deviation for

Deffense [45]

Answer:

5.10 people

Step-by-step explanation:

Calculation to Find the standard deviation for the number of people with the genetic mutation

Using this formula

Standard deviation = √ ( n * p * q)

Where,

n = 400

p = .07

q = 100%-7% = 93% or .93

Let plug in the formula

Standard deviation =√400*07*.93

Standard deviation =√26.04

Standard deviation = 5.10 people

Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.
