A car dealer ship is having a sale in which customers pay 85% of the retail price for a new vehicle. Keith is buying a vehicle w

muminat

Answer:

$27,84.6

Step-by-step explanation:

Since the company offers 85% of the retail as sale price

Sale price=0.85*36,00=$30,60

Since Keith negotiates, he gets 91% of the sale price

Keith pays= 0.91*30,60=$27,84.6

Therefore, before tax, Keith pays $27,84.6

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximatel

Murrr4er [49]

Answer:

The monument is approximately 86.6 feet tall

Step-by-step explanation:

The given monument parameters are;

The distance of the person from the monument = 50 feet

The angle of depression from the top of the monument to the person's feet = 64°

Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;

tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)

∴ The height of the monument = tan(Angle of depression) × The distance from the monument

Substituting the known values, gives;

The height of the monument = tan(60°) × 50 ≈ 86.6

The height of the monument ≈ 86.6 feet.

Cat behavior: A report stated that the average number of times a cat returns to it's good bowl during the day is 37. Assuming th

Virty [35]

Answer:

P (34<X<39) = 0.5899

Step-by-step explanation:

When the distribution is normal, we use 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.

In this question, we have that:

$\mu = 37, \sigma = 3$

What is the probability that a cat would return to it's dish between 34 and 39 times a day.

This is the pvalue of Z when X = 39 subtracted by the pvalue of Z when X = 34. So

X = 39

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

$Z = \frac{39 - 37}{3}$

$Z = 0.67$

$Z = 0.67$ has a pvalue of 0.7486

X = 34

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

$Z = \frac{34 - 37}{3}$

$Z = -1$

$Z = -1$ has a pvalue of 0.1587

0.7486 - 0.1587 = 0.5899

So

P (34<X<39) = 0.5899
