Costs for standard veterinary services at a local animal hospital follow a Normal distribution with a mean of $72 and a standard
Romashka [77]

Answer:

P(32

And we can find this probability with this difference:

P(-1.905

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(-1.905

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the costs of services of a population, and for this case we know the distribution for X is given by:

X \sim N(72,21)  

Where \mu=72 and \sigma=21

We are interested on this probability

P(32

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

P(32

And we can find this probability with this difference:

P(-1.905

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(-1.905

How many terms are there in the following expression? x - 5 + 16x + 4 - 2x - 3
k0ka [10]

Answer:

Two terms

Step-by-step explanation:

First, we have to simplify reducing the number of terms, since there are like terms

x-5+16x+4-2x-3

Eventually, you'll get 15x-4,  thus there are two terms.

Please correct me if I'm incorrect, and I'll change the answer, but I hope I helped :)

Kevin estimated the differncle between of 9/10 minus 4/8 to be 0 is his estimate reasonable explain
raketka [301]

Answer:

No, it is not reasonable

Step-by-step explanation:

Writing 9/10 and 4/8 as fractions out of 100, and then as decimals

9/10 = 90/100 = 0.9

4/8 = 1/2 = 50/100 = 0.5

0.9 - 0.5 = 0.4

Not 0, like Kevin estimated
