Answer:

Answer is $10,144.50

Step-by-step explanation:

15% of 220 =33

220- 33 = 187

8.5% of 187 =15.89

187+15.89=202.89

202.89 x 50 =10,144.50

If g(x) = 2(x − 4), find the value of x if g(x) = 20. 32 12
nlexa [21]

Answer:

The value of x is 14

Step-by-step explanation:

we have

g(x)=2(x-4) ------> equation A

In this problem we have

g(x)=20

Substitute the value of g(x) in the equation A and solve for x

20=2(x-4)

Divide by 2 both sides

20/2=2(x-4)/2

10=(x-4)

Adds 4 both sides

10+4=(x-4)+4

x=14

The lengths of a particular snake are approximately normally distributed with a given mean mu = 15 in. and standard deviation si
Helga [31]

The percentage of the snakes is longer than 16.6 in. with a mean of 15 in. and a standard deviation of 0.8 in. is 2.275%.

<h3>What is a normal distribution?</h3>

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The lengths of a particular snake are approximately normally distributed with a given mean = 15 in. and standard deviation = 0.8 in.

Then the percentage of the snakes is longer than 16.6 in. will be

z = \dfrac{ x - \mu }{ \sigma }\\\\z = \dfrac{16.6-15}{0.8}\\\\z = 2

Then we have

\rm P(x > 16.6) = P(z > 2) = 0.02275  \ or  \ 2.275 \%

More about the normal distribution link is given below.
