An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment values shown in the table:
Enrollment Month
January February March April May June
Actual 500 400 550 550 750 400
Predicted 410 450 650 650 600 450
Residual 90 −50 −100 −100 150 −50
Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.

12. Convierte estas fracciones impropias en números mixtos:
A. 15/7=
B. 16/6=
C. 12/5=
D. 48/7
Por favor.
¡Hola! Voy a hacer el mismo proceso para cada uno.
Primero, restaré el denominador del numerador hasta que sea una fracción propia. También simplificaré si es necesario.
Luego, "volveré a sumar los números enteros al número" como un número mixto.
A. 15/7
[tex]\displaystyle \frac{15-7-7}{7} =\frac{1}{7}[/tex]
[tex]\displaystyle \frac{1}{7}+1+1=[/tex]
[tex]\displaystyle 2\frac{1}{7}[/tex]
B. 16/6
[tex]\displaystyle \frac{16-6-6}{6} =\frac{4}{6}=\frac{2}{3}[/tex]
[tex]\displaystyle \frac{2}{3}+1+1=[/tex]
[tex]\displaystyle 2\frac{2}{3}[/tex]
C. 12/5
[tex]\displaystyle \frac{12-5-5}{5} =\frac{2}{5}[/tex]
[tex]\displaystyle \frac{2}{5}+1+1=[/tex]
[tex]\displaystyle 2\frac{2}{5}[/tex]
D. 48/7
[tex]\displaystyle \frac{48-7-7-7-7-7-7}{7} =\frac{6}{7}[/tex]
[tex]\displaystyle \frac{6}{7}+1+1+1+1+1+1=[/tex]
[tex]\displaystyle 6\frac{6}{7}[/tex]

Get the slope of the line using the two known points:
slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3
Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,
y - 6 1/4 = 3 (x - 3/4) ⇒ y = 3x + 16/4 = 3x + 4
Then for some given value of x, the third point has y-coordinate 3x + 4.
"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.
Fill in the blank to make the statement true.
1 3 over 4 space plus space 1 over 6 space plus ________ equals space 7 1 half
Answer: x= 385/12
Step-by-step explanation:
You would first change the denominator to some number that is common. Then combine the like terms. Lastly, subtract the fraction from the equal and you get your x.
[tex]\frac{13}{4} +\frac{1}{6} +x=\frac{71}{2} \\(\frac{39}{12})+(\frac{2}{12})+x=\frac{426}{12} \\\frac{41}{12}+x=\frac{426}{12} \\x=\frac{385}{12}[/tex]

Answer:
3) 1/6
4) 1/2
5) 1/2
6) 1/3
7) 1/2
8) 1/3
9) 0
10) 1
11) 5/6
12) 1/3
Step-by-step explanation:
3) There is only one 2 on a die. Thus, the probability would be 1/6.
4) There are 3 even numbers on a die (2, 4, 6). Thus, the probability would be 3/6 which simplifies down to 1/2.
5) There are also 3 odd numbers on a die (1, 3, 5). Thus, the probability would be 3/6, which again simplifies down to 1/2.
6) There are only 2 numbers greater than 4 on a die (5, 6). This makes the probability 2/6, which simplifies to 1/3.
7) There are 3 numbers less than 4 on a die (1, 2, 3). This makes the probability 1/2.
8) The probability of getting a 6 or 2 is 1/3. This is because when the probability statement says "or" you add the probabilities of the individual events to get the probability. In this case it would be 1/6 + 1/6 which equals 2/6, simplified to 1/3.
9) The probability of rolling a 7 is 0. There is no 7 on the die, so you would not be able to roll a 7.
10) All the numbers on a die are less than 10, this makes the probability 1.
11) There are 5 other numbers that aren't "5" on the die, this makes the probability 5/6.
12) Composite numbers are a number that can be formed by multiply 2 smaller numbers together. There are only 2 on a die, 4 and 6. Four is a composite number because 2*2 = 4. Six is a composite number because 3*2 = 6. Therefore, the probability will be 1/3 (2/6).

what is the measure of angle 7?
suppose the measure of angle 6 can be represented be (2x-5). what equation can be written to solve the value of x?
what is the value of x?
Answer:
<7 = 47, 2x - 5 + 47 = 180, x = 69
Step-by-step explanation:
<5 and <7 are vertical angles, which means that they have the same degree.
<7 + <6 = 180. <6 = 2x - 5. 2x - 5 + 47 = 180.
Solve
2x - 5 + 47 = 180
2x + 42 = 180
2x = 138
x = 69

Answer:
r = -21
Step-by-step explanation:
-2(r + 9)
-2 (-21 + 9)
-21 + 9 = -12
-2(-12)
= 24
Answer:
-21
Step-by-step explanation:
Detailed explanation:
24 = -2(r + 9)
First, I did distributive property
24 = -2r -18
Now I will add 18 to both sides
42 = -2r
Now I will divide both sides by -2
-21 = r

Find the surface area if the regular pyramid
Answer:
170.1 yd^2
Step-by-step explanation:
In picture attached
Answer:
205.2
Step-by-step explanation:
First get the area's of the 3 triangles on top of the base, the formula is base x height divided by 2
10 x 9 = 90
90 / 2 = 45
Multiply the area of the 3 sides together :
45 x 3 = 135
Now find the area of the base triangle :
9 x 7.8 = 70.2
To find the surface area of the ENTIRE shape you have to add all the sides :
135 + 70.2 = 205.2
