Fill in the blank. tripling the radius of a sphere increases the surface area by a factor of ___________.

1 answer:

7 0

To solve this completion exercise, you must keep on mind the following information:

- The formula for calculate the area of a sphere, is the following:

Vsphere=4πr³/3

Where Vsphere is the volume of the sphere and "r" is the radius of the sphere.

- Therefore, if you multiply the radius by 3, or triple the radius, the surface area increase by a factor of 9 (3^2=9).

The answer is: T<span>ripling the radius of a sphere increases the surface area by a factor of 9.</span>

Given that the data distribution is approximately normal with the minimum value of 15 and the maximum value of 98 a) Estimate th

andrew11 [14]

Answer:

a) Mean, median, mode = 56.5

b) $S = 20.75$

Step-by-step explanation:

Normally distributed data have the same value for the mean, median and mode. This value is the addition of the maximum value by the minimum, divided by 2.

Also, the standard deviation in a normally distributed sample can be approximated by the following formula:

$S = \frac{max - min}{4}$

a) Estimate the values of Mean, Median, and Mode.

Highest value = 98

Minimum value = 15

$\mu = \frac{98 + 15}{2} = 56.5$

b) Estimate the value of the standard deviation of these data

Max = 98

Min = 15

$S = \frac{max - min}{4}$

$S = \frac{98 - 15}{4}$

$S = 20.75$

alukav5142 [94]

Answer:

760.93 i think!

Step-by-step explanation:

7 x 100=700

6 x 10=60

9 x (1/10)=0.9

3 x (1/100)=0.03

700+60+0.9+0.03=760.93
