Answer:

f(2) = 0

Step-by-step explanation:

Put 2 in the place of x,

f(2) = 4 - 2(2)

f(2) = 4 - 4

f(2) = 0

Tire pressure monitoring systems (TPMS) warn the driver when the tire pressure of the vehicle is 26% below the target pressure.
ZanzabumX [31]

Answer:

a) 22.94 psi

b) 5.93\times10^{-5}

Step-by-step explanation:

a)The pressure at which will trigger a warning is

31 - 31*0.26 = 22.94 psi

b) The probability that that the TPMS will trigger warning at 22.94 psi, given that tire pressure has a normal distribution with average of 31 psi and standard deviation of 2 psi

f(x)={\frac {1}{\sigma {\sqrt {2\pi }}}}e^{-{\frac {1}{2}}\left({\frac {x-\mu }{\sigma }}\right)^{2}}

where x = 22.94, \mu = 31, \sigma = 2

f(22.94)={\frac {1}{2 {\sqrt {2\pi }}}}e^{-{\frac {1}{2}}\left({\frac {22.94-31}{2 }}\right)^{2}}

f(22.94)=0.2e^{-8.12} = 5.93\times10^{-5}

Vita wants to center a towel bar on her door that is 27 1/2 inches wide. She determines that the distance from each end of the t
timurjin [86]

Answer:

The equation is x+18 =\frac{55}{2}..

The length of the towel bar is \frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in..

Step-by-step explanation:

Given,

Length of the door = 27\frac{1}{2}\ in

we can rewrite 27\frac{1}{2}\ in as  \frac{55}{2}\ in.

We have to find out the length of the towel bar.

Let the length of towel bar be 'x'

`Since Vita wants that the distance from each end of the towel bar to the end of the door to be 9 inches.

So we can say that the length of the towel bar plus  from each end of the towel bar to the end of the door plus  from each end of the towel bar to the end of the door  is equal to length of door.

framing in equation form, we get;

x+9+9= \frac{55}{2}\\\\x+18 =\frac{55}{2}

Hence The equation is x+18 =\frac{55}{2}.

Now we solve the equation we get;

Subtracting both side by 18 we get;

x+18-18=\frac{55}{2}-18\\\\x=\frac{55}{2}-18

Now we will make the denominator common we get;

x=\frac{55}{2} -\frac{18\times2}2= \frac{55}{2} -\frac{36}2 = \frac{55-36}{2}=\frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in

Hence The length of the towel bar is \frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in.

Determine the common difference for each arihmetic sequence 1,5,9,13
Zolol [24]
The common difference is 4. If you look at the numbers 1 and 5, there is a difference of 4. If you look at 5 and 9, there is also a difference of 4. If you look at 9 and 13, there is a difference of 4. Therefore, in this arithmetic sequence, the common difference is 4.
