T.L. and Quina plan to add a 6-inch thick layer of gravel to their driveway. The driveway is 15 yards long and 3 yards wide. Wha

Artemon [7]

Answer:

Step-by-step explanation:

The driveway has the shape of a cuboid. The formula for determining the volume if a cuboid is expressed as

Volume = L × W × H

Where

H represents the thickness of the gravel to be added to the driveway.

W represents the width of the driveway.

L represents the length of the driveway.

From the information given,

L = 15 yards

W = 3 yards

H = 6 inches.

36 inches = 1 yard

6 inches = 6/36 = 0.167 yard

Therefore, the volume of gravel required would be

V = 15 × 3 × 0.167 = 7.515 cubic yards

The heights of the trees in a forest are normally distributed, with a mean of 25 meters and a standard deviation of 6 meters. Wh

Alla [95]

Answer:

2.3%

Step-by-step explanation:

The formula to convert x into z distribution is

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

Where z is the test statistic

x is what we are looking for (in this case 37)

$\mu$ is the mean (in this case, it is 25)

$\sigma$ is the standard deviation (we have 6)

Plugging these into the formula, we get:

$z=\frac{x-\mu}{\sigma}\\z=\frac{37-25}{6}\\z=2$

Thus we can say we want $P(z\geq 2)$

Note: $P(z\geq a)=1-P(z\leq a)$

The table given is for any z where $P(z\leq a)$

Thus, now we have:

$P(z\geq 2)\\=1-P(z\leq 2)\\=1-0.9772\\=0.0228\\$

0.0228 into percentage is 0.0228 * 100 = 2.28%

Rounded, we get 2.3%

Third answer choice is right.

Answer: $5x+3y+1=0$

Step-by-step explanation:

Given

The linear equation is $5x+3y-9=0$

The other linear equation parallel to the given line can be represented by

$5x+3y+c=0$

Here, c can take any value . for example c=1, line becomes

$\Rightarrow 5x+3y+1=0$
