For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

A system of equation is shown.
5x+2y=245
y=x+6
Enter a numeric value to complete the solution of the system.
Answers
Answer:
y = 245 / 7, x = 29
Step-by-step explanation:
make both into ax + by = c format which is
Math:
5x + 2y = 245
-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.
[(Side Note) if both were positive then you would need to do
EX: - 5 (- x + y = 6)]
Continued:
7y = 275 ==> 7y/7 = 245/7
y = 245 / 7
Plug it in the most convenient one which has the equation y = x + 6
and tweak it a bit
x = y - 6
x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7
x = 203 / 7 ==> 29
Y=x+6
Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answers
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

Answer:
slope: (positive) 2
y-intercept: -4
Step-by-step explanation:
slope is rise over run, rise is 2 up every 1 over, so slope is (2-0)/1
y-intercept is where the function intercepts or crosses the y-axis, that is at -4
Answer:
Slope = 2/1
Y-intercept = -4
Equation: y= 2/1 -4
Step-by-step explanation:
The y intercept is where the line passes through y (the vertical line).
For slope, I like to think rise-over-run. You can count up (y) and across (x) for untill it intercepts.
Slope Equation:
(y2-y1)/(x2-x1)
(-4-2)/(0-3)
(-6)/(-3) --> negatives cancel eachother out.

Find the diagonal of the box, AD, using the Pythagorean Theorem twice - 1. To find BD and 2. To find AD.
AB = 12 in
BC = 18 in
CD = 4 in
Show all steps for findin the diagonal of the box above using the formula instead of the Pythagorean Theorem twice.
Answers
Answer:
BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22Step-by-step explanation:
You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.
Pythagorean theorem twiceThe length of BD can be found from ...
BD² = BC² +CD²
BD² = 18² +4² = 340
BD = √340 ≈ 18.439
and
AD² = AB² +BD²
AD² = 12² + 340 = 484
AD = √484 = 22
The lengths of the face and space diagonals are ...
BD = √340 ≈ 18.439AD = 22FormulaNo formula is given as part of the problem statement. We can simplify the above calculations to get ...
AD² = AB² +BD²
AD² = AB² +BC² +CD²
AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula
AD = √(12² +18² +4²) = √(144 +324 +16) = √484
AD = 22

Answer:
Sharon is wrong in step 2.
Step-by-step explanation:
So, basically we need to look at how Sharon step by step solved this problem.
We need to check her work by solving it ourselves, and seeing what she did wrong.
So we have:
9=-3(e-2)
The first thing that we need to do is distrubute the -3 to the e and -2:
9=-3e+6
This is looks like step 1 of Sharon's work.
Now, we need to get -3e alone by getting all the numbers to one side. This means we need to get rid of the 6 by subtracting 6 from both sides:
3=-3e
This doesnt look like what Sharon got.
She has:
15=3w
How did she do this? Note everything from here to the next bolded words explains her incorrect method of solving.
Well, what if we factor out a negative sign, making -3e into 3e?
This would make +6 into -5.
Then you would get:
9=-(3e-6)
The reason why you CANNOT do this is one problem.
Anything that has been factored(basically a value that has had something taken from it), such as the - in our case, cannot be subtracted or added to another number.
The reason you cannot subtract or add a factored number is it changes the value of the answer. So pretty much subtracting and adding factored numbers is BIG NO NO.
Back to how we solve for e.
So we have already gotten to step 2 with:
3=-3e
Lets get e alone by dividing both sides by -3.
3/-3=-1.
-3e/-3 = e.
So our answer, in step 3 is:
-1=e
This is not needed for your answer, and only shows how you can double check your answer.
So if oyu arent 100% sure with this, lets double check.
We got -1 as e, so lets plug it into our orginal equation:
9=-3(e-2)
Plug in -1:
9=-3(-1-2)
Distrubute the -3:
9=3+6
Add together the numbers:
9=9
This is correct!
Hope this helps!
