In a survey, patients are asked how long they sat in their doctor's waiting area. The results for two doctors are shown below.
Doctor #1 (waiting time in minutes): 5, 10, 10, 15, 20, 20, 20, 100
Doctor #2 (waiting time in minutes): 10, 10, 10, 20, 20, 20, 25, 25
Based on the results, what is the best measure of center to compare the data, and how do the measures compare?
The median is the best measure. The median waiting time for Doctor #1 is 7.5 minutes longer than for Doctor #2.
The mean is the best measure. The mean waiting time for Doctor #2 is 2.5 minutes longer than for Doctor #1.
The mean is the best measure. The mean waiting time for Doctor #1 is 7.5 minutes longer than for Doctor #2.

1- One number is 10 less than twice another. If their difference is 31, what is the larger number?
87
72
75
2-
Given the system of equations, what is the solution?
2x + y = 7
2x - 3y = -1
{( , 2)}
{(2, )}
{(1, )}
3-
Which of the following systems is equivalent to the given system?
x - y = 1
x + y = -1
2x - 3y = 6 and 4x + y = 4
4x - 3y = 6 and 4x - y = -4
4x + 3y = -6 and 4x - y = 4
4- Given the system of equations, match the following items.
2x + y = -1
x - 5y = 4
5-
If the second equation is multiplied by 5 and then the equations are added, the result is _____.
x + 5y = 3
2x - y = -2
9x = 13
11x = -7
9x = -7
Answer:
See answers below with explanations
Step-by-step explanation:
Problem 1:
One number is 10 less than twice another.
This translates to n=2m-10
Their difference is 31
This translates to n-m=31
n-m=31
(2m-10)-m=31
m-10=31
m=41
n-41=31
n=72
Therefore the larger number is (B) 72
Problem 2:
Use elimination:
2x + y = 7
- 2x -3y = -1
4y = 8
y = 2
2x+2=7
2x=5
x=2.5
Therefore the solution is (A) {(2.5,2)}
Problem 3:
Use elimination:
x - y = 1
- x + y = -1
-2y = 2
Check if each answer eliminates to -2y=2:
2x - 3y = 6
4x + y = 4
-2x - 4y = 2 NO
4x - 3y = 6
4x - y = -4
-2y = 10 NO
4x + 3y = -6
4x - y = 4
4y = -10 NO
Neither answer is correct
Problem 4:
No visible items to match
Problem 5:
2(2x - y = -2)
4x - 2y = -4
x + 5y = 3
4x - 2y = -4
5x + 3y = -1
None of the answer choices are correct

Solving system of equations by substitution!
Please help :'(
Answer:
x=-3
Step-by-step explanation:
because in the first equation it is saying that 4x+5 is also equal to the second equation, -1/3x-8. then you would do -1/3x-8=4x+5, then(letters to the left) -4x on bothe sides,which then you get -13/3x-8=5, then +8 on both side, then you get -13/3x=13, last you divied by -13/3 and youj get x=-3

A local pizza shop has a membership program for frequent buyers. The membership costs $15 per month and members get a discounted price of $1 per slice of pizza. Parker purchased a membership to this pizza shop. How much would Parker have to pay the pizza shop if he bought 20 slices of pizza this month? What would be the monthly cost for xx slices of pizza?
Answer:
$34
$26.5
Step-by-step explanation:
Membership cost per month = $25
Price of a slice of pizza for members= $1.50
How much would Aaliyah have
to pay the pizza shop if she bought 6 slices of pizza this month
Total cost of Aaliyah on 6 slices of pizza = membership cost per month + prices of 6 discounted pizza
= $25 + $1.50(6)
= $25 + $9
= $34
What would be the
monthly cost for a slices of pizza
Monthly cost of Aaliyah a slices of pizza = membership cost per month + price of 1 discounted pizza
= $25 + $1.5
= $26.5

Please mark as Brainliest!!!ASAP 20 points - Which expression best estimates 6 and 3/4 divided by 1 and 2/3?
A. 7 divided by 2
B. 6 divided by 1
C. 8 divided by 3
D. 3 divided by 2
Answer:
A. 7 divided by 2
Step-by-step explanation:
The computation is shown below;
[tex]= 6\frac{3}{4} \div 1 \frac{2}{3} \\\\= \frac{27}{4} \div \frac{5}{3}\\\\= \frac{27}{4} \times \frac{3}{5}\\\\= \frac{27\times 3}{4\times 5} \\\\= \frac{81}{20} \\\\= 4 \frac{1}{20}[/tex]
It could be 4.05
So according to the given options, the option 1 is chosen at is closed to 4.05
Hence, the option A is correct
2. y is inversely proportional to cube of x.
When x = 2, y = 4.
Find y when x = 4
(3 Points)
Answer:
y = 0.5 at x = 4
Step-by-step explanation:
According to question,
y is inversely proportional to cube of x i.e.
[tex]y\propto \dfrac{1}{x^3}\\\\y=\dfrac{k}{x^3}[/tex]
or
[tex]k=yx^3[/tex]
Put x = 2 and y = 4 in above expression to find k.
[tex]k=4\times (2)^3\\\\=32[/tex]
Now put x = 4 to given equation to find y.
[tex]y=\dfrac{32}{4^3}[/tex]
y = 0.5 or 1/2
So, the value of y is 0.5 when x = 4.
