The volume of a rectangular prism is 75 cubic inches. The height is 3 inches.

mylen [45]

Answer:

A) 5 in. long and 5 in. wide

Step-by-step explanation:

Given:

Volume of a rectangular prism = 75 cubic inches

Height of prism = 3 inches

Volume of a rectangular prism is given by = $l\times w\times h$

where $l$ representslength of base, $w$ represents width of base and $h$ represents height of the prism.

We will check the choices given by finding the volume for the given dimensions of length and width while height remains the same and see if it matches with the given volume of the prism.

A) $l=5\ in$ $w=5\ in$

Volume of prism = $5\times 5\times 3=75\ in^3$

B) $l=10\ in$ $w=2\ in$

Volume of prism = $10\times 2\times 3=60\ in^3$

C) $l=5\ in$ $w=4\ in$

Volume of prism = $5\times 4\times 3=60\ in^3$

D) $l=15\ in$ $w=5\ in$

Volume of prism = $15\times 5\times 3=225\ in^3$

So, we see that the dimensions given in option A would give the volume of prism = 75 cubic inches.

A normal curve with a mean of 500 and a standard deviation of 100 is shown. Shade the region under the curve within one standard

N76 [4]

Answer:

And for this case we want to find how much of the data within the shaded region given in the figure attached.

And we can use the zscore formula given by:

$z = \frac{X -\mu}{\sigma}$

And if we find the z score for the limits we got:

$z = \frac{400-500}{100}=-1$

$z = \frac{600-500}{100}= 1$

And we want to find this probability using the normal standard distribution or excel:

$P(-1$

So we would expect about 68.2 % of the data within one deviation from the mean

Step-by-step explanation:

For this case we know that the variable of interest let's say x follows a normal distribution with the following parameters:

$X \sim N(\mu = 500, \sigma =100)$

And for this case we want to find how much of the data within the shaded region given in the figure attached.

And we can use the zscore formula given by:

$z = \frac{X -\mu}{\sigma}$

And if we find the z score for the limits we got:

$z = \frac{400-500}{100}=-1$

$z = \frac{600-500}{100}= 1$

And we want to find this probability using the normal standard distribution or excel:

$P(-1$

So we would expect about 68.2 % of the data within one deviation from the mean

Katherine is landscaping her home with juniper trees and pansies. She wants to arrange 15 pansies around each of 8 trees. Each t

garik1379 [7]

The expression that signifies Katherine’s final cost F= P + T= $466

<h3>Calculation of final cost</h3>

The number of pansies to be arranged around each tree = 15 pansies

The cost of pansies(P) = 15 × 8 × 2.50 = $300

The number of juniper trees available = 8

The cost of the trees available(T) = 8 × 20.75= $166

Therefore Katherine's final cost(F)= $300 + $166 = $466

The expression to find Katherine’s final cost = F= P + T
