After 5 years the value will only be 9000

1.) Subtract $24,000-$9,000 to find out how much the car value would depreciate down to.
2.) Then divide it by $3,000 to find out how many years it would take for the car's value to depreciate that low.

I am a little tired right now so I hope you understand my explanation on how to solve the problem. :) Good luck!

The table lists the test scores William and Andre received on five math assessments. Which student had the higher median? By how

Sever21 [200]

Answer: c

First you organize the numbers into order then you find the middle of both. The middle of Williams was 89. Then you do the same for Andres and you get 82. To get the difference of them both you have to subtract both of them to get 7 and that’s c.

Given that x is a normally distributed random variable with a mean of 50 and a standard deviation of 2, find the probability tha

Shkiper50 [21]

Let X be the normal variable with mean μ =50 and standard deviation σ =2

We have to find probability that x is between 47 and 54

P(47 < X < 54) = P(X < 54) - P(X < 47)

= $P(\frac{x-mean}{standard deviation}$ - $P(\frac{x-mean}{standard deviation}$

= P(Z < 2) - P(Z < -1.5)

Using standard normal z score table to find probabilities we get

P(Z < 2) = 0.9772

P(Z < -1.5) = 0.0668

P(47 < X < 54) = P(Z < 2) - P(Z < -1.5)

= 0.9772 - 0.0668

P(47 < X < 54) = 0.9104

The probability that x is between 47 and 54 is 0.9104

For what value of \$x\$ is the function \$\\frac{1}{x-2}\$ not defined?

natima [27]

for the value of $x=2$ we have the function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ as undefined or not defined .

Step-by-step explanation:

Function undefined: A function is undefined when it gives results which are not defined for example , infinity .

Here we have , Function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ . We need to find a value of for which this is not defined . Let's find out:

We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or $x-2=0$

⇒ $x-2=0$

⇒ $x-2+2=0+2$

⇒ $x=2$

Therefore, for the value of $x=2$ we have the function f(x) = 1/(x-2) or $f(x)=\frac{1}{x-2}$ as undefined or not defined .
