How do you find the valume in a triangle prism

1 answer:

6 0

A trangular prisim is 1/3legnth times width times height
because a triangular prisim is 1/3 volume of a rectangular prisim of the same height and base
so equation is 1/3lwh

A music store marks up the instruments it sells by 40%. If the store bought a guitar for $35, what will be its store price? If t

Black_prince [1.1K]

Answer:

a. $49

b. $74.28

c. No

Step-by-step explanation:

The computation is shown below:

a. The store price is

= Purchase price + markup

= $35 + $35 × 40%

= $35 + $14

= $49

b. The price paid is

Since there is a markup of 40% and when it is added to 100% of cost so the selling price is 140% of the cost or 1.40 of the cost

Now the price paid is

$104 = 1.40 × cost

So, the cost is

= $104 ÷ 1.40

= $74.28

c. Now the markup is

= $100 - $75

= $25

The markup percentage is

= $25 ÷ $75

= 33.33%

No the store does not markup the price by 40%

The amount of soft drink in a bottle is a Normal random variable. Suppose that in 7% of the bottles containing this soft drink t

WITCHER [35]

Answer:

The mean is 15.93 ounces and the standard deviation is 0.29 ounces.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

7% of the bottles containing this soft drink there are less than 15.5 ounces

This means that when X = 15.5, Z has a pvalue of 0.07. So when X = 15.5, Z = -1.475.

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

$-1.475 = \frac{15.5 - \mu}{\sigma}$

$15.5 - \mu = -1.475\sigma$

$\mu = 15.5 + 1.475\sigma$

10% of them there are more than 16.3 ounces.

This means that when X = 16.3, Z has a pvalue of 1-0.1 = 0.9. So when X = 16.3, Z = 1.28.

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

$1.28 = \frac{16.3 - \mu}{\sigma}$

$16.3 - \mu = 1.28\sigma$

$\mu = 16.3 – 1.28\sigma$

From above

$\mu = 15.5 + 1.475\sigma$

$15.5 + 1.475\sigma = 16.3 – 1.28\sigma$

$2.755\sigma = 0.8$

$\sigma = \frac{0.8}{2.755}$

$\sigma = 0.29$

The mean is

$\mu = 15.5 + 1.475\sigma = 15.5 + 1.475*0.29 = 15.93$

The mean is 15.93 ounces and the standard deviation is 0.29 ounces.

Answer:

The equation of the line is $y = 3x + 3$

Step-by-step explanation:

Looks like you've already found the y-intercept and slope of this graph. Great! That's all the info we need to create an equation.

The equation of a line is always in $y = kx+b$ form, where k is the constant of proportionality (aka the slope) and b is the constant added (aka the y-intercept).

We know the slope is 3 and the y-intercept is 3, so we can put these values into the equation.

$y = 3x+3$

Hope this helped!
