Find the value of y.
Answer:
y is 3.6
Step-by-step explanation:
The information given are
Parallel lines crossing two converging lines with proportion 3 and 5 on one and 6 and y on the other
To find y, we have that two or more parallel lines cut by two transversal proportionately cut the transversal lines;
Therefore we have from the measured segment of the two lines;
[tex]\dfrac{3}{5} = \dfrac{y}{6}[/tex]

The line of symmetry of the parabola whose equation is y = ax2 - 4x + 3 is x = -2. What is the value of "a"?
-2
- 1/2
-1
Answer:
a = -1
Step-by-step explanation:
The line of symmetry for the parabola given by ...
y = ax² +bx +c
is
x = -b/(2a)
Using the given values, we have ...
-2 = -(-4)/(2a)
Multiplying by -a/2, we get ...
a = (4/2)(-1/2) = -1
The value of "a" is -1.
Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality.
8 and 13
Explanation:
Let x be the length of the third side. We can't find the exact value of x, as we don't have enough info, but we can find possible values for x.
The lower boundary for x is 13-8 = 5. It must be larger than this value.
At the same time, x must be smaller than 13+8 = 21 as well.
So x > 5 and x < 21 becomes 5 < x < 21
In short, x is between 5 and 21. It cannot equal either endpoint.

1. Create your own data set with an interquartile range of 17.
2. Explain how you decided which numbers to use.
3. Show the math that shows the interquartile range is 17.
Hey there! I'm happy to help!
The IQR is how far apart the first and third quartiles are, which are the middle numbers of the first and second halves of a data set. Let's find some random numbers that are 17 apart. We will use 3 and 20.
Now, we have to create a data set where 3 is the middle number of the first half and 20 is the middle number of the second half. Let's have one with six numbers because that's a good amount I guess. Remember that the data has to be going from least to greatest.
In our first half we will have one number that is smaller than 3 and one bigger than three so that 3 is in the middle. Here's an example of what our first half should look like:
2,3,5
Now, for our second half, we need a number smaller than 20 and one greater than 20 so 20 is the the middle. Here's the second half I've made for you.
16,20,100
So, the data set I've created for you is 2,3,5,16,20,100. However, there are many other possibilities as you've seen.
My answers for your question 1 and 2 are in the explanation I've done, and here's the math that shows that the interquartile range is 17.
You split the data in half.
2,3,5, 16,20,100
Q1 is the middle number of the first, which is 3. Q3 is the middle of the second, which is 20.
You find how far apart they are by subtracting 3 from 20.
20-3=17.
The IQR is 17.

If the variance of a variable is 16, what is the standard deviation?
Answer:
Standard deviation=4
Step-by-step explanation:
Standard deviation = square root of variance
Standard deviation=√variance
Variance=standard deviation square
Variance=standard deviation^2
From the question
Variance=16
Standard deviation=?
Standard deviation=√variance
=√16
=4
Standard deviation=4
check:
If standard deviation=4
Variance=standard deviation^2
=4^2
=16
Therefore,
Standard deviation=√variance
[tex]4[/tex]
VarianceThe variance is a measure of how much each point deviates from the mean on average.The standard deviation of a set of numbers is the distance between them and the mean. (The mean is the arithmetic average of a given group of integers.)To compute the standard deviation, take the square root of the variance.Variance of the variable [tex]=16[/tex]
Standard deviation [tex]=\sqrt{16}[/tex]
[tex]=\boldsymbol{4}[/tex]

Divide his points by teams points and multiply by 100:
160/640 = 0.25
0.25 x 100 = 25%
He scored 25% of the total points.
Answer:
25%
Step-by-step explanation:
640/140=4
james was responsible for 1/4 of the points which is equal to 0.25 when 1 is divided by 4, which times 10 is equal to 25, so the answer is 25%

ASAP its not 36 do RSM way Find the number of rectangles in 6×6 chessboard.
Answer:
441 rectangles
Step-by-step explanation:
Formula for the number of rectangles in a chessboard=
n²(n + 1)²/ 4
We are told in the question that is a 6×6 chessboard
Hence, n = 6
= 6²(6 + 1) ²/ 4
= 6²× 7²/4
= 36 × 49/4
= 1761/4
= 441 rectangles
Therefore, the number of rectangles in 6×6 chessboard is 441 rectangles.

a , [tex]5\frac{9}{14}[/tex]
b,[tex]7\frac{1}{2}[/tex]
Answer:
A) 5 9/14
B) 7 1/2
Step-by-step explanation:
Question A asks what is 4 1/7 + 1 1/2
First turn the problem into improper fraction for it to be easier to calculate.
29/7 + 3/2
Now we have to find the denominator(bottom number)
We have 7 and 2 as our denominators. So we need to find out the lcm(least common factor)
For 7 and 2 the lcm is 14
So far we have:
29/7 + 3/2 = ?/14 + ?/14 = ?
Now we need to find the numerator(The top number). That fills in the ? over the two 14's.
To find the numerator we need to mutiply.
29/7 + 3/2 = ?/14 + ?/14 = ?
7 × ? = 14 the answer is 2 so then we multiply the top also with 2. So 29 × 2 = 58.
29/7 + 3/2 = 58/14 + ?/14 = ?
Now we have figured out one of the ?
We do the same thing for the other one
2 × ? = 14 answer is 7 so we also multiply the top with 7. 3 × 7 = 21.
29/7 + 3/2 = 58/14 + 21/14 = ?
Now we have to solve this:
58/14 + 21/14 = ?
The denominator is 14 because both of them are 14.
The top we need to add together so 58+21= 79
Now our answer is:
79/14
If we simplify it(by turning into improper fraction):
5 9/14
B) question is 4 1/2 ÷ 3/5
First we turn it into inproper fraction
9/2 ÷ 3/5
Since it is divsion we have to flip the second fraction which is 3/5 into 5/3, and turn the ÷ symbol into ×
9/2 × 5/3
Now we multiply across
9×5 = 45
2×3 = 6
answer: 45/6
Now if we simplify:
7 1/2

Answer:
49π
Step-by-step explanation:
Circle area: πr^2
Since A to C is 14, and they're both in the center, A to B and B to C will both be 7 as a radius.
Since we know the radius, we can put it in the formula, πr^2.
We only need to solve for one circle, since both circles are the same. By solving the circle, we will put in 7 for the radius, giving us π7^2, which is 49π.

Write h(x) = x2 - 6x + 3 in vertex form by following these
steps:
Step 1: Model x2 - 6x + 3 by placing tiles in the Product
section. First place the x2 and -x tiles along the left
and top borders to form two sides of a square. Then
place the + tiles along the ends of the -x tiles.
The vertex form of the quadratic equation is:
[tex]h(x) = (x - 3)^2 - 6[/tex]
How to write the quadratic equation in vertex form?
For a quadratic equation:
[tex]y = a*x^2 + b*x +c[/tex]
With vertex (h, k), the vertex form is:
[tex]y = a*(x - h)^2 + k[/tex]
In this case, we have the equation:
[tex]h(x) = x^2 - 6x + 3[/tex]
To get the x-value of the vertex we use the general formula:
[tex]h = -(-6)/(2*1) = 6/2 = 3[/tex]
To get the y-value, we evaluate the function in x = 3, so we get:
[tex]h(3) = k = (3)^2 - 6*3 + 3 = -6[/tex]
So the vertex is (3, -6).
Then the vertex form is:
[tex]h(x) = (x - 3)^2 - 6[/tex]

The surface area of a rectangular prism that has height of 4 inches, width of 9 inches and length of 3 inches = ____________ in2.
Answer:
150 in^2
Step-by-step explanation:
The ends have the smallest surface area. The total surface area of the ends is thus 2(3 in)(4 in) = 24 in^2
The top and bottom together have the total surface area 2(9 in)(3 in) = 54 in^2.
Finally, the front and back surface areas together are 2(9 in)(4 in) = 72 in^2
Thus, the total surface area is (24 + 54 + 72) in^2 = 150 in^2
Surface area of a rectangular prism is equal to [tex]\boldsymbol{150}[/tex] square inches.
Surface area of a rectangular prismHeight of a rectangular prism [tex]=4[/tex] inches
