What is the least positive integer by which 24 should be divided so that the resulting integer is a perfect square?
24 = 2 × 2 × 2 × 3
In a perfect square, all the prime factors occur in pairs.
In 2 × 2 × 2 × 3, 2 occurs in a pair, and only one each of 2 and 3 remains unpaired.
So, the least positive integer by which 24 should be divided to get a perfect square = 2 × 3 = 6.

What is the least positive integer by which 24 should be divided so that the resulting integer is a perfect square?
If we actually guess and check by dividing by 1, then 2, then 3, then etc. we will get the answer. I tried and divided by 6, which is 4, which is a perfect square. Do not trust me completely on this, for I am not quite sure.
3a: complete the table with values for x and y that makes this equation true 3x+y=15
3b: create a graph, plot these points, and find the slope of the line that goes through them.
Answer:
a. see the attachment for the table (also reproduced below)
b. slope = -3; see the attachment for a graph
Step-by-step explanation:
A table of values for the function can be filled a couple of ways. One way is to draw the graph of the equation, and read the point values from it. Another way is to solve for each of the variables, and use those equations to find the missing table values.
__
a.Solving the equation for y, we get ...
3x +y = 15
y = -3x +15 . . . . . . subtract 3x; this is "point-slope form"
For the purpose of evaluating for different values of x, we can rearrange this a bit to ...
y = 3(5 -x) . . . . factor out 3
The given table has x-values of 0, 2, 3, 6. The corresponding y-values are ...
y = 3(5 -{0, 2, 3, 6}) = 3{5, 3, 2, -1} = {15, 9, 6, -3} . . . . for x={0, 2, 3, 6}
Solving the equation for x, we get ...
y/3 = 5 -x . . . . . divide the above equation by 3
x = 5 -(y/3) . . . . . add x-(y/3)
For y-values {0, 3, 8}, the corresponding x-values are ...
x = 5 -{0, 3, 8}/3 = 5 -{0, 1, 8/3} = {5, 4, 7/3} . . . . for y={0, 3, 8}
Then our table of values is ...
[tex]\begin{array}{|c|c|c|c|c|c|c|c|}\cline{1-8}x&2&4&6&0&3&5&7/3\\y&9&3&-3&15&6&0&8\\\cline{1-8}\end{array}[/tex]
__
b.The points in the above table can be plotted, and the line drawn through them. Sometimes using the points that are farthest apart makes this easier: (0, 15) and (6, -3).
slope
When we solved for y, we had the equation in slope-intercept form. The slope is the x-coefficient in that equation:
y = -3x +15 ⇒ slope = -3
Which data set contains an outlier:
(Will give 25 points!) Solve the system of linear equations by substitution. 3x - 2y = 12 and 4x + 2y = 16
Let
Eq1 : x - 2y = 12
Eq2 : 4x + 2y = 16
For substitution, we need to rearrange on of the equations so that we can substitute it in the other. Let's pick eq2 and rewrite it as 2y = 16 - 4x. We see that eq1 also has 2y in it, so we can plug this new version of eq2 in there.
3x - (16-4x) = 12
Now solve for x.
7x=28, so x=4
Plug that into either equation to solve for y. You get y=0.
So your answer is x=4, y=0
Answer:
i think its X squared=y squared +4

Keiko surveyed people with cell phones.
Ages in years = a
Texts they send per day = t
He drew a best-fit line and determined its equation.
Evaluate how many texts a 15 year old would send each day according to Keiko's trend line equation.
Answer:
67.69
Step-by-step explanation:
You have your equation, t = -1.63 a + 92.14
a = age
a = 15
if you update your equation to fill in for a you get:
= -1.63 (15) + 92.14
-1.63 x 15 = -24.45
-24.45 + 92.14 = 67.69
67.69
Answer:
67.69
Step-by-step explanation:
You have your equation, t = -1.63 a + 92.14
a = age
a = 15
if you update your equation to fill in for a you get:
= -1.63 (15) + 92.14
-1.63 x 15 = -24.45
-24.45 + 92.14 = 67.69
67.69

Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P'Q'R' has vertices P'(1, −2), Q'(0, 3), and R'(−1, 0).
Plot triangles PQR and P'Q'R' on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer.
Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis.
Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer.
Answer:
Part A :
The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is divided by 3.
Part B :
P"(-1,2), Q"(0,3), R"(1,0)
Part C :
Triangle PQR and P"Q"R" are not congruent because congruent means equal and similar but triangle PQR and P"Q"R" are proportional because they are rational to each other but do not have the same measures of sides but the angles are congruent.
This is the graphing of the triangle.
I'm trying to find .580 (only the 80 is repeating in the decimal) rewritten as a simplified fraction. thanks in advance, this one is really tricking me up.
Answer:
Step-by-step explanation:
assuming its repeating as .580808080 etc your answer would be 115/198 :)
Answer:
115/198
Step-by-step explanation:
.580 = .5808080
.5808080 = x
5.808080 = 10x
58.08080 = 100x
580.8080 = 1000x
1000x - 10x = 575
575 = 990x
x = 575/990
Simplify:
575/990 = 115/198

The number of hours of TV watched each week by 8 seventh grade students is shown below.
11, 7, 9, 3, 3, 8, 10, 5
a. What is the mean number of hours of TV watching?
b. Mean absolute deviation =
c. Explain the meaning of the mean absolute deviation as it relates to the number of hours of TV watched.
Answer:
a) 7 hours ; b) 2.5 hours ; c) look at explanation
Step-by-step explanation:
a)
The mean of a data set is what we usually refer to as the average. To find the mean, you add up all of the values and divide by the number of values.
So, to find the mean, you need to add all of the values (the "value" is the the number hours each student watched)
11 + 7 + 9 + 3 + 3 + 8 + 10 + 5
= 56
You have 8 seventh-grade students, so your number of values is 8.
Dividing the sum of the values by the number of values would then be:
56 / 8
= 7
So, your mean is 7.
---------------------------------------
b)
(A deviation is how much a value differs from a certain value. If a person was supposed to be 5 feet tall, and they were 6 feet tall, they would deviate 1 foot from the value of 5. If the person was 4 feet tall, they would also have a deviation of 1 foot.)
The mean absolute deviation is complicated. You probably want to set up two columns (or at least this is how I was taught to do it), the first column being the value (represented by x in the mean absolute deviation formula), the second column being the difference between the mean of the data set and the value (the mean is represented as x with a line over it).
∑ is the sum of the values of the second column.
To find the mean (remember, mean = average) of the deviations, you are going to add all of the deviations together, and divide by your number of values.
I'll write out the second column (the difference from mean) below:
| x - [tex]\frac{}{x}[/tex] |
4
0
2
4
4
1
3
2
if you add all of these values up, you will get 20; ∑ = 20
[ | | means absolute value--essentially the distance of the value from 0, so a negative number is written as a positive numbers; |-3| = 3 ; |3| = 3 ]
Now you will find the mean of your deviations. The sum of all deviations (∑) = 20. The number of deviations/the number of values is 8.
So, the equation of 20 / 8 will give us the absolute mean deviation.
20/8 = Mean Absolute Deviation
Mean Absolute Deviation = 2.5
Your Mean Absolute Deviation is 2.5 [hours] .
------------------------------------------------
c)
Now you are being asked to interpret what this 2.5 indicates. It means that each student has, on average, a difference of 2.5 hours of TV watched from the mean. The Mean Absolute Deviation gives us a sense of how spread out the values of a data set are. We know that a mean absolute deviation of 0 would indicate that all values of the set are exactly identical. A mean deviation of 100 would indicate that all of the values are drastically different. So, a mean deviation of 2.5 indicates that all of the values (each student's watch hours) are fairly similar.

simplify 2(-n-3)-7(5+2n)
Answer:
-16n - 41
Step-by-step explanation:
To simplify the equation, you need to get rid of the parentheses by multiplying the numbers outside the parentheses to the numbers inside. Then, you can combine the similar terms.
2(-n - 3) - 7(5 + 2n) <---- Original equation
-2n - 6 - 7(5 + 2n) <---- Expand first parentheses by mult.
-2n - 6 - 35 - 14n <---- Expand second parentheses by mult.
-16n - 6 - 35 <---- Combine terms with "n"
-16n - 41 <---- Combine whole numbers
Answer:-2n-29

3 is divisible by 3.
Answer:
The digit that makes the statement true is 2...hope this helps:)
Answer:
The digit is two.
Step-by-step explanation:
It is very simple, to find if a number is divisible by 3 specifically, you need to add all the digits together. All the digits together added up to 37, which is not divisible by 3. But if you make the missing digit 2 then the digits add up to 39 which is divisible by 3.
