A professional singer charged $1000 an hour. Her rate increase by 50% after midnight. If she performs one night from 8:30pm to 1

otez555 [7]

First we need to find out what her increase is so 50% of 1000 is is 500 so from 12am to 1am she made
1500
from 830 to 12 am gives us 4 1/2 hours so she got paid 4500 for those hours adding on the past 12am and we get

6000 as the total amount she made

Rectangular implies the area to be length times height

let height=x

let width=2 more than the height or Length=2+x

Area=F(x)=(2+x)(x)=2x+x^2

f(x)=x^2+2x

****************To Answer your Additional question

You see the standard price is $100 for any mural, And also charges $40 per square foot.

So to show you the approach, Lets say that a mural of 1 square feet needs to be painted, then the charge will be $100 plus the $40 for every square feet, then it will be 100+40(1 square feet)=$140.

The problem asks for the charge of mural whose area is x, so lets do the same thing.

$100+40(x square feet)=100+40x and that is the function that gives the price of mural with an area of x.

so, g(x)=100+40x

Lost-time accidents occur in a company at a mean rate of 0.40.4 per day. What is the probability that the number of lost-time ac

o-na [289]

Answer:

1.32% probability that the number of lost-time accidents occurring over a period of 88 days will be no more than 22.

Step-by-step explanation:

To solve this question, i am going to approximate the Poisson distribution to the normal to solve this question.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval. The variance is the same as the mean.

Normal probability distribution:

Problems of normally distributed samples can be 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.

The poisson distribution can be approximated to the normal with mean $\mu$ and standard deviation $\sigma = \sqrt{\mu}$
