Answer:
By IQR , i hope you meant inter quartile range
Steps:
Step 1: Put the numbers in order.
[tex]2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7[/tex]
Step 2: Find the median.
[tex]2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7[/tex]
Step 3: Place parentheses around the numbers above and below the median. (it makes Q1 and Q3 easier to spot.)
[tex](2, 3, 3, 4, 4,) 4, (4, 5, 5, 6, 7)[/tex]
Step 4: Find Q1 and Q3
Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.
[tex](2, 3, 3, 4, 4,) 4, (4, 5, 5, 6, 7)\\\\Q_{1} = 3 \ and \ Q_{3}= 5[/tex]
Step 5: Subtract Q1 from Q3 to find the interquartile range.
[tex]IQR =Q_{3}-Q_{1} =5-3=2[/tex]

What is an equation of the line that passes through the points (1,3) and (8,5)?
Answer:
y=2/7x+19/7
Step-by-step explanation:
Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7
Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:
y=2/7x+b
3=2/7(1)+b
3=2/7+b
21/7=2/7+b
19/7=b
Therefore, our final equation is y=2/7x+19/7

Answer:
40 shots total.
Step-by-step explanation:
First, change the percentage to a decimal:
80% = 80/100 = 0.80
Next, divide the amount of baskets made (32) with the decimal gotten to get the total amount of shots:
32/0.80 = 40
Brandon took a total of 40 shots.
Check. Divide 32 (shots made) with the 40 (total shots in all):
32/40 = 0.8 = 80%.

Y=2x+3 and y=x+2 what is the x,y
Answer:
x=-1, y=1
Step-by-step explanation:
Answer:
( -1, 1 )
Step-by-step explanation:
To solve, graph the equations and find the point of intersection.
when graphed these equations intersect at (-1, 1)
To double-check and make sure it's correct, plug in a solve.
x = -1
y = 1
y = 2(-1) + 3
1 = 2(-1) + 3
1 = -2 + 3
1 = 1
y = x + 2
1 = (-1) + 2
1 = 1
A linear function that represents the number of hot dogs purchased at a football game is compared to a different linear function that represents the time left in the game. Describe the key features of the functions that are needed to determine if these lines intersect.
The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.
Solve the system of equations and choose the correct ordered pair. 5x+2y= 19 4x - 3y - 6 A (3,5) B. (5-3) C. (5,3) D. (3,2)
Answer:
(3,2)
Step-by-step explanation:
5x+2y= 19
4x - 3y = 6
I will use elimination
Multiply the first equation by 4
20x +8y = 76
Multiply the second equation by -5
-20x +15y = -30
Add them together to eliminate x
20x +8y = 76
-20x +15y = -30
---------------------------
23y = 46
Divide by 23
23y/23 = 46/23
y =2
Now find x
5x+2y =19
Substitute y=2
5x+2(2) =19
5x+4 = 19
Subtract 4 from each side
5x +4-4 =19-4
5x= 15
Divide by 5
5x/5 = 15/5
x=3
The solution is

−20x+24=0, which number would have to be added to "complete the square"?
Considering the equation of the parabola in vertex form, it is found that a number of -100 would have to be added to complete the square.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
[tex]y = a(x - h)^2 + k[/tex]
In which a is the leading coefficient.
In this problem, the equation is:
[tex]x^2 - 20x + 24[/tex]
Placing it in vertex form, we would have:
[tex](x - 10)^2 + 24 + c[/tex]
Applying the square of the subtraction:
[tex](x - 10)^2 = x^2 - 20x + 100[/tex]
Hence, a number of -100 would have to be added to complete the square.

Please help me I really need help
Answer:
A, C
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
the ∠A is adjacent (adj) to AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle
which one of the above trig functions fits that?
sin(Ф) = BC / AC is sin(Ф)= Opp / Hyp , so choice A) works
cos(Ф) = BC / AC is not cos(Ф) = Opp / Hyp so choice B) does not work
cos(Ф) = BA / AC is cos(Ф) = Adj / Hyp so choice C) works
AC / BC is just a ratio it's not the angle , so D) doesn't work

Answer and Step-by-step explanation:
As we can see by the given figure, we can cut out 2 rectangular prisms from this shape.
This gives us an easier time to find the volume. We will be using the volume formula for rectangular prisms: Length × Width × Height
The first prism has side lengths of:
Height = 6
Length = 11
Width = 7 (from the two 2's and the one 3 added together -- 2 + 2 + 3 = 7)
Let's multiply these values together.
6 × 11 × 7 =
66 × 7 =
462 -- First volume
The second prism has side lengths:
Height: 6
Length: 9
Width: 3
Let's multiply these values together.
3 × 6 × 9 =
3 × 56 =
168 -- Second volume
Now, we add together the volumes to get the volume of the composite figure.
168 + 462 = 630
The volume of the composite figure is 630 cubic feet.

How much lace edging is needed to go around a circular tablecloth with a diameter of 6 ft?
Answer:
A= 28.27 ft²
Step-by-step explanation:
if its trying to find area for a circle then we use the formula A=πr²
A=π(3)²
A= 28.27 ft²
Answer:
the answer is 18.85ft
Step-by-step explanation:
the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:
C = 2πr
input the values you have into the formula
C= 2 x π x 3
(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)
put that into your calculator and youll get the answer
C= 18.8495559215
(i rounded the answer to two decimal places = 18.85ft)

Use the following trinomial to answer the questions. x^2-6x-27 When going through the process of determining the factors, the two factors need to : add up to ___ multiply to ___
Answer:
The factors are 3 and -9
Step-by-step explanation:
The given trinomial is [tex]x^2-6x-27[/tex].
We need to find two factors. We know that,
3(9) = 27
So,
[tex]x^2-6x-27[/tex] can be written as :
[tex]x^2+3x-9x-27[/tex] as two factors add up to get -6 and multiply to get -27.
Hence, the factors are 3 and -9.
