plug in 2y-4 in x of the second equation meaning 7(2y-4)+5y=-66
multiply and combine like terms then solve for y and you should get -2
then plug in -2 for y in the first equation and you should be able to solve for x
Data were collected on the following variables. Which variable is LEAST likely to be approximated with a normal model?
A) The distribution of heights of tomato plants growing at an agricultural center, where most heights cluster around the center and there are some very short and very tall heights
B) The distribution of times that a certain brand of house paint lasts on a house, where the distribution is symmetric and bell-shaped
C) The distribution of lengths of the trout living in a certain stream, where the distribution is unimodal and clustered around the center, and the left half is a mirror image of the right half
D) The distribution of weights of mold samples growing in a laboratory, where the distribution is symmetric, unimodal, and does not have any outliers
E) The distribution of ages, in years, of all the residents of a town, where the right tail of the distribution is longer than the left
Answers
Answer:
E) The distribution of ages, in years, of all the residents of a town, where the right tail of the distribution is longer than the left
Step-by-step explanation:
Because the distribution is described as having a tail on the right that is longer than the left, it is skewed right and not a normal model.

What is the inverse function of f(x) = x/x-2
Answers
9514 1404 393
Answer:
f^-1(x) = 2x/(x -1)
Step-by-step explanation:
You can find the inverse function by solving for y:
[tex]f(y)=x\\\\\dfrac{y}{y-2}=x\\\\x(y-2)=y \qquad\text{multiply by $y-2$}\\\\xy-2x=y \qquad\text{eliminate parentheses}\\\\xy-y=2x \qquad\text{add $2x-y$}\\\\y(x-1)=2x \qquad\text{factor}\\\\y=\dfrac{2x}{x-1} \qquad\text{divide by the coefficient of $y$}\\\\\boxed{f^{-1}(x)=\dfrac{2x}{x-1}} \qquad\text{in functional form}[/tex]

what is the value of x
Answers
Answer:
70°
Step-by-step explanation:
All triangles' angles are added up to 180°
30 + 80 + x = 180
110 + x = 180
x = 180 - 110
x = 70
Answer:
[tex]x = 70[/tex]
Step-by-step explanation:
[tex]x = 180 - (30 + 80)[/tex]
[tex]x = 180 - 110[/tex]
[tex]x = 70[/tex]
to be sure
[tex]70 + 80 + 30 { = }^{?} 180[/tex]
[tex]100 + 80 { = }^{?} 180[/tex]
[tex]180 = 180[/tex]

A copy machine can print 340 color copies every 8 minutes. Explain or show your reasoning.
A teacher printed 850 copies. How long did it take to print?
Answers
Step-by-step explanation:
340=8min
850=?(x)
340x=850×8
340x=6800
x=6800/340
x=20min
so..the teachertook 20 minute to print 850 copies
340 copies every 8 minutes
Find copies per minute
340 / 8 = 42.5 copies/min
Now, to find out how long it took to print all 850 copies;
850 / 42.5 = 20 min.
It took 20 minutes.
Or
(850*8) / 340 = 20

Which equation is a linear function?
y=2^x -1
y=x/2-5
y=2/x +3
y=x^2 +7
Answers
Answer:
Second Choice.
Step-by-step explanation:
[tex]y = mx + b[/tex]
That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.
So we can cut out the first and last choice.
Then we have only two choices which are
[tex]y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3[/tex]
The second equation is called Rational Function where a variable is a denominator.
Therefore, the correct answer is second choice.
Your family spends $30 for tickets to an aquarium and $3 per hour for parking. Write an equation that gives the total cost of your family's visit to the aquarium as a function of the number of hours that you are there. Find the total cost of 4 hours at the aquarium
Answers
Answer:
Equation: y=$3(x)+$30
Total cost $42
Step-by-step explanation:
Calculation to Find the total cost of 4 hours at the aquarium using this formula
y=mx+b
Where,
y intercept=Total cost
m=$3 per hour
b=$30 Tickets
x=4 hours
Let plug in the formula
First step is to form the equation
y=$3(x)+$30
Second step is to substitute 4 hours for m and b
y=$3(4)+$30
Hence:
y=$12+$30
y=$42
Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42

is 68 m. If one side is represented by 3x + 2,
what is the value of x?
A 3
B 5
C 4
D 6
E 10
Answers
Answer:
The answer is B, 5.
Step-by-step explanation:
3x+2 is per side. A square has 4 sides. 3x+2 times 4 is 12x+8 (using the distributive property).
12x+8 = 68
12x = 60
divide both sides by 12...
60/12 = 5.
Therefore x =5
