Problem 2. A random variable has the following density function:
f (x) = 1- 0.5x 0 < x < 2
a. Graph the density function.
b. Verify that f(x) is a density function.
If f(x) is a density function, then its integral over the entire real line should be 1:
[tex]\displaystyle\int_{-\infty}^\infty f(x)\,\mathrm dx=\int_0^2(1-0.5x)\,\mathrm dx=(x-0.25x^2)\bigg|_0^2=2-1=1[/tex]
so yes, f(x) is indeed a density function.
And.... next?

There are 3,785 milliliters in 1 gallon, and there are 4 quarts in 1 gallon.
How many milliliters are in 3 gallons?
Label your answer in mL.
Answer:
11,355
Step-by-step explanation:
Because it's 3,785 per gallon, you just have to multiply that by three, which gets you 11,355

Step-by-step explanation:
Here is my question. Take your time because this is a hard question.
Answer: x=25
Step-by-step explanation:
This is mainly algebraic calculations, so it's just using operations. You can open the parentheses in any order you want, but I started with the numerator of the first expression. I simplified it to get 3.8-3.3, which is the same as 0.5 Then I moved on to the denominator of the second equation. Distribute the 0.8, then add it to 3.2, getting 5. The numerator is a bit trickier. There's a lot of LCMs to find, but first multiply 5/66 by 2 1/2. You can use the butterfly method to simplify it, and get 1/33. Use LCMs to subtract the 3 fractions, getting a result of 1/12. Using cross multiplication, you get the result of x=25.
Two horses start a race at the same time. Horse A gallops at a steady rate of 32 feet per second and Horse B gallops at a steady rate of 28 feet per second. After 5 seconds, how much farther will Horse A have traveled? Explain or show your reasoning.
Answer:
20 feet
Step-by-step explanation:
The horse is running 4 feet per second faster than horse B so you multiply that 5 times because it's after 5 seconds

If x= time in minutes, y= distance in miles, and y=1/6x. How far can you run 5 points
in 30 minutes?*
Answer:
You can run 5 miles in 30 minutes.
Step-by-step explanation:
y = [tex]\frac{1}{6}[/tex] x
y = [tex]\frac{1}{6}[/tex] (30)
y = 5 miles
You can run 5 miles in 30 minutes.

You can use Y2-Y1/X2-X1 to find the slope. Then, you can use y=mx+b to find the y-intercept.
Assume a significance level of α=0.05 and use the given information to complete parts (a) and (b) below.
Original claim: Less than 51% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0148
a. State a conclusion about the null hypothesis. (Reject Upper H0 or fail to reject Upper H0
Choose the correct answer below.
A.Reject Upper H0 because the P-value is less than or equal to to α.
B. Reject Upper H0 because the P-value is greater than α.
C. Fail to reject Upper H0 because the P-value is greater than α.
D. Fail to reject Upper H0 because the P-value is less than or equal to α.
b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion?
A. The percentage of adults that would erase all of their personal information online if they could is less than or equal to 51%.
B.There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%.
C. The percentage of adults that would erase all of their personal information online if they could is more than 51%.
D. There is not sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%.
Answer:
A.Reject Upper H0 because the P-value is less than or equal to to α.
B.There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 51%.
Step-by-step explanation:
Given the claim :
Less than 51% will erase their personal information :
We take this as the null ;
H0 < 0.51 ;
Alternative hypothesis which is the opposite of the Null
H1 > 0.51
P value = 0.0148
α = 0.05
At α = 0.05 ; if p value is less than α ; reject the the Null
If p value is greater than Null ; then we fail to reject the Null
Pvalue < α
The P value is less than 0.05; then we reject the Null
B.) There is significance evidence to support the Alternative hypothesis claim, that the percentage of adult that would erase all their personal information online if they could is more Than 51%

An EWMA control chart uses λ = 0.5. What is the value of L such that the control limits of this EWMA control chart in the steady state have the same width with a 3σ X_bar control chart?
Answer:
5.199
Step-by-step explanation:
From the information provided;
We know that λ = 0.5.
However, the control limits for a steady-state EMWA control chart is:
[tex]\mu_o \pm L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
where;
[tex]UCL = \mu_o + L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
[tex]LCL = \mu_o- L \sigma \sqrt{\dfrac{\lambda }{(2-\lambda )n}}[/tex]
Given that the data is chosen from an individual sample;
Then; we can express the width as:
[tex]L \sigma \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3 \sigma[/tex]
[tex]L \sqrt{\dfrac{\lambda}{(2-\lambda)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(2-0.5)}}= 3[/tex]
[tex]L \sqrt{\dfrac{0.5}{(1.5)}}= 3[/tex]
[tex]L \sqrt{0.333}= 3[/tex]
[tex]L\times 0.577= 3[/tex]
[tex]L=\dfrac{ 3 }{0.577}[/tex]
L = 5.199
