The Range of the given function weight is; [4,000 , 5,800]
How to find the range of a function?The range of a function is defined as the set of all possible output values of that function.
We are Given:
Function; W = 6F + 4000
Full amount of fuel = 300 gallons
No amount of fuel = 0 gallons
Thus, the set of all possible input values which is the domain is;
Domain : amount of fuel = [0 , 300]
If F = 0, then we have;
W = 6F + 4,000
W = 6(0) + 4,000
W = 4,000
If F = 300, then we have;
W = 6F + 4,000
W = 6(300) + 4,000
W = 5,800
Thus, we conclude that the Range of weight is; [4,000 , 5,800]

Using your answer(s) for question 3, were there any extraneous answers, and how did you check?
Question 3 was:
(Solve |2(x-5)|+11=17)
The answer is x = 8 and x = 2
Answer:
x = 8 and x = 2 are both valid solutions.
There are no extraneous answers.
Step-by-step explanation:
Given absolute value function:
[tex]|2(x-5)|+11=17[/tex]
To solve an equation containing an absolute value, isolate the absolute value on one side of the equation:
[tex]\implies |2(x-5)|+11=17[/tex]
[tex]\implies |2(x-5)|+11-11=17-11[/tex]
[tex]\implies |2(x-5)|=6[/tex]
Set the contents of the absolute value equal to both the positive and negative value of the number on the other side of the equation, then solve both equations.
Equation 1 (positive)
[tex]\implies 2(x-5)=6[/tex]
[tex]\implies \dfrac{2(x-5)}{2}=\dfrac{6}{2}[/tex]
[tex]\implies x-5=3[/tex]
[tex]\implies x-5+5=3+5[/tex]
[tex]\implies x=8[/tex]
Equation 2 (negative)
[tex]\implies 2(x-5)=-6[/tex]
[tex]\implies \dfrac{2(x-5)}{2}=\dfrac{-6}{2}[/tex]
[tex]\implies x-5=-3[/tex]
[tex]\implies x-5+5=-3+5[/tex]
[tex]\implies x=2[/tex]
Therefore, the solutions are x = 8 and x = 2.
Check if the solutions are valid by substituting them into the original equation:
[tex]\begin{aligned}x=8 \implies |2(8-5)|+11 & =17\\|2(3)|+11 & =17\\|6|+11 & =17\\6+11 & =17\\ 17 & = 17\end{aligned}[/tex]
[tex]\begin{aligned}x=2 \implies |2(2-5)|+11 & =17\\|2(-3)|+11 & =17\\|-6|+11 & =17\\6+11 & =17\\ 17 & = 17\end{aligned}[/tex]
Therefore, both solutions are valid and there are no extraneous answers.
Note: An extraneous solution is a solution that is produced by solving the problem, but is not a valid solution to the problem.

x less than or equal to 25
Answer:
[tex]x\leq 25[/tex]
Step-by-step explanation:
Since x can equal anything 25 and lower, here are some of the possibilities x can be.
x = 25, 24, 23, 22, 21, 20, etc.
X could also be a decimal and doesn't have to be an integer.
x = 24.7, -20.4, 24 5/7
So to put these numbers in one equation, we can use the [tex]\leq[/tex] symbol.
Therefore, [tex]x\leq 25[/tex].

What is the measure of the missing angle? show your work.
The measure of the missing angle is 112°.
Sum of Interior AngleWhen you need to find some interior angle of polygons, you can apply the formula for the sum of interior angle. This formula relate the number of sides of the polygon with the sum of interior angle. The formula is presented below.
S = (n – 2 )*180º, where:
S= sum of interior angles
n= number of sides of the given polygon
The given figure shows:
a polygon with 5 sides ;the angles of polygon are: 105°,118°,75°, 130° and x°.Applying the formula, S = (n – 2 )*180º, you find:
S=(5-2) * 180
S=3*180
S=540°
Now that you know the sum of the interior angles for the given polygon, thus:
x+105+118+75+130=540
x+428=540
x=540-428
x=112°

A bakery sold 26 vanilla cupcakes in a day, which was 13% of the total number of
cupcakes sold that day. How many total cupcakes did the bakery sell that day?
The total number of cupcakes sold by the bakery on that day were 200.
Here, we are given that a bakery sold 26 vanilla cupcakes in a day.
This was 13% of the total number of cupcakes sold that day.
Let the total number of cupcakes sold that day be x
Then 13% of x is given to be 26. Mathematically this can be represented as-
(13/100)x = 26
solving the equation to find the value of x, we get-
x = 26 × 100/ 13
x = 26/13 × 100
x = 2 × 100
x = 200
Thus, the total number of cupcakes sold by the bakery on that day were 200.

Accrotime is a company that manufactures quartzcrystal watches. Accrotime researchers have shown that the watches have an average life of 28 months before certain electronic componentsdeteriorate, causing the watch to become unreliable. The standard deviation of watch lifetimes is 5 months, and the distribution of lifetimes is normal.
if Acro time does not want to make refunds for more than 12% of the watches it makes how long should the guarantee period be to the nearest month
if acro time guarantees a full refund on any defective watch for two years after purchase what percentage of total production should the company expect to replace
The guarantee period of the electronic components by Accrotime manufactures is 38 months.
What is defined as the normal distribution?A normal distribution is a data set arrangement in which the majority of values cluster inside the middle of the range and the remainder trimmed off symmetrically toward any extreme.It happens whenever a normal random variable does have a mean of zero and a standard deviation of one.mean = μ = 24 months
standard deviation = σ = 5 months
2 years = 24 months
a) P(x < 24)
= P[(x - μ ) / σ < (24 - 28) / 5]
= P[(x - μ ) / σ < -0.8
= P(z < -0.8 )
Using z table,
= 0.212
Percentage = 21.2%
b) Use standard normal table,
Refund percentage = 12%
P(Z > z) = 12%
= 1 - P(Z < z) = 0.12
= P(Z < z) = 1 - 0.12
= P(Z < z ) = 0.88
= P(Z < 0.174 ) = 0.94
z = 0.174
Using z-score formula,
x = z ×σ + μ
x = 1.74 × 5 + 28
x = 36.7

• For software that really has a virus, the test says "Yes" 97% of the time
• For software that is really virus-free, the test says "Yes" 2% of the time ("false

If 1% of all software has a virus and the virus test for a randomly selected software says
"Yes", what are the chances that the software really has a virus?
There is 0.329 probability or chance that the software really has a virus.
The calculation will be based on Bayes' theorem which relates the probability and statistics, as is mentioned in the given question. The values provided are True positive = 97%, False positive = 2% and Prevalence = 1%.
Probability = (True positive × user) ÷ (True positive × user) + (false positive × non user)
Keep the values in formula to find the probability
Probability = (0.97 × 0.01) ÷ (0.97 × 0.01) + (0.02 × 0.99)
Probability = 0.0097 ÷ (0.0097 + 0.0198)
Probability = 0.0097 ÷ 0.0295
Probability = 0.329

The school that Ming goes to sell their tickets as follows: price of a senior citizen ticket is $6 and the price of a student ticket is $9
How to find the price of a senior citizen ticket and the price of a student ticket
Given data
first day 8 senior citizen tickets and 4 student tickets for a total of $84
second dat 8 senior citizen tickets and 2 student tickets for a total of $66
let the price of a senior citizen ticket be x and the price of a student ticket be y. The equation is written as:
8x + 4y = $84 equation 1
8x + 2y = $66 equation 2
subtracting equation 2 from equation 1
( 8x - 8x ) + 4y - 2y = 84 - 66
0 + 2y = 18
2y = 18
y = 9
substituting y = 9 into equation 1
8x + 4y = 84
8x + 4 * 9 = 84
8x + 36 = 84
8x = 84 - 36
8x = 48
x = 6
