The sample data below shows the number of hours spent by five students over the weekend to prepare for Monday's Business Statist

Levart [38]

Answer:

8.5 hrs

Step-by-step explanation:

-A 75th percentile mathematically means that 75% of the time data points are below that value and 25% of the time are above that value.

-We plot the given our data {3 12 2 3 5} to determine the 75th percentile

#We can use $alcula.com$ to plot our boxplot.

-From the plot, we find our 75th percentile to be 8.5 hrs

Hence, 75% of the time the number of hours spent to prepare was less than 8.5hrs.

Eddie has saved up $45 to purchase a new camera from the local store. The sales tax in his county is 7% of the sticker price. Wr

NARA [144]

tax gets added to the price of the camera

so the equation is:

Help me understand please

Answer:

V=pi x (r)^2 x h

V-volume r-radius h-height

V= pi x (3)^2 x 9

V= pi x 9 x 9

V= pi x 81

V= 254.47 (rounded)

Each side of a cube measures 5 cm in length. What is the cubes volume?

AysviL [449]

Answer:

Your answer would be 125 cm³

____________________________________________________

Step-by-step explanation:

In order to find the volume of a cube, we would need to use the right formula to find the volume for it.

Volume of a cube formula:

$V = a^{3}$

For our "a" value, we would need to plug in our side value, and for you case, the side value would be 5.

In a cube, all of the sides would be the same size, so you don't have to worry about using any different numbers.

Lets plug in 5 to our equation.

$V = 5^{3}$

Now we solve:

$5^{3} = 125\\$

This is also the same as:

$5 *5*5 = 125$

Your FINAL answer should be 125 cm³
