Answer:
48°60°72°Step-by-step explanation:
The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:
4×12° : 5×12° : 6×12° = 48° : 60° : 72°
Angles 1 to 3 are 48°, 60°, 72°, respectively.

What is the definition of independent samples? A. All samples of the same size have an equal chance of being selected from the population. B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population. C. The sample selected from one of the populations is paired with a sample selected from the other population.
Answer:
B. The sample selected from one of the populations has no effect or bearing on the sample selected from the other population.
Step-by-step explanation:
In statistical analysis, the use of independent samples for diverse studies is common.
Independent samples are such that the sample selected from one of the populations has no effect or bearing on the sample selected from the other population.
This means that samples are selected randomly in such a way that an observation obtained from a sample does not depend on the values obtained from the observation of another sample from the other population.

what is the range of f?
Answer:
Range is [tex]-5 \le y \le 5[/tex]
Range in interval notation is [-5, 5]
==========================================================
Explanation:
Refer to the diagram below. As marked in red, the smallest y value is y = -5. The largest y value is y = 5. The range is the set of y values between these endpoints, including both endpoints.
We can say the range is [tex]-5 \le y \le 5[/tex]
In interval notation, we write that as [-5, 5]. The use of square brackets tells the reader that the endpoints are included as part of the range.

A clown weighs 60 lb more than a trapeze artist. The trapeze artist weighs two-thirds as much as the clown. How much does each weigh?
Answer:
Step-by-step explanation:
well if the clown weighs 60 lbs more than the trapeze artist...
and the trapeze artist is 2/3 the weight of the clown...
then the trapeze artist must weigh 120 lbs..
and the clown must weigh 180 lbs..
i hope this was correct lol

(2, -1)
-10
Answer:
([tex]\frac{5}{2}[/tex], 3)
Step-by-step explanation:
I got 5/2 as my x variable and 3 for my y variable to being the midpoint. In which I added both my x variables provided ( 3 and 2 ) and then I divided them by two to get half of that (since you are looking for in between those two digits technically so you are wanting to find the midpoint or the middle of that line segment). I also did the same with the two y variables as well which were 7 and -1, then I divided both by two to get the variable 3.
Answer:
5/2, 3
Step-by-step explanation:
that should be your answer (hopefully)

Answer:
[tex]57\frac{3}{11}[/tex] = c
or
[tex]57.\overline{27}[/tex] = c
Step-by-step explanation:
We know that the diameter of a circle multiplied by [tex]\pi[/tex] is the circumference, so we can create this equation:
180 = c * [tex]\pi[/tex]
Your teacher told us to assume [tex]\pi[/tex] is 22/7, so we'll put that in
180 = c * [tex]\frac{22}{7\\}[/tex]
To get c by itself, we divide both sides by 22/7
[tex]\frac{180}{\frac{22}{7}}[/tex] = c
Dividing by a number is the same as multiplying by its reciprocal, so we'll multiply 180 by 7/22
180 * [tex]\frac{7}{22}[/tex] = c
Evaluate
[tex]\frac{1260}{22}[/tex] = c
[tex]57\frac{3}{11}[/tex] = c
If you want a decimal instead:
[tex]57.\overline{27}[/tex] = c
In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10/?
Quadratic formula: * = -bt/b? 40c

O x=5+31
O x = 51/19
O x = 5+219
O x = 5+2/31
Answer:
[tex]x = 5 \± \sqrt{31}[/tex]
Step-by-step explanation:
Given
[tex]6 = x^2 - 10x[/tex]
Required
The solution in radical form
[tex]6 = x^2 - 10x[/tex]
Rewrite as:
[tex]x^2 - 10x - 6 = 0[/tex]
Using the quadratic formula, we have:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
a = 1
b = -10
c = -6
So, we have:
[tex]x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{100 +24}}{2*1}[/tex]
[tex]x = \frac{10 \± \sqrt{124}}{2}[/tex]
Split the roots
[tex]x = \frac{10 \± \sqrt{4 * 31}}{2}[/tex]
Express [tex]\sqrt 4[/tex] as 2
[tex]x = \frac{10 \± 2\sqrt{31}}{2}[/tex]
Split the fraction
[tex]x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}[/tex]
[tex]x = 5 \± \sqrt{31}[/tex]

The following estimated regression equation was developed for a model involving two independent variables.
ŷ =40.7+8.63x1+2.71x^2
After x2 was dropped from the model, the least squares method was used to obtain an estimated regression equation involving only x1 as an independent variable.
ŷ= 42.0+9.01x1
Required:
a. Give an interpretation of the coefficient of x1 in both models.
b. Could multicollinearity explain why the coefficient of x1 differs in the two models? If so, how?
Answer:
(a): y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second
(b): Yes
Step-by-step explanation:
Given
[tex]\wedge y = 40.7 + 8.63x_1 +2.71x_1[/tex]
[tex]\wedge y = 42.0 + 9.01x_1[/tex]
Solving (a): An interpretation of x1 coefficient
We have the coefficients of x1 to be 8.63 and 9.01
Literally, the coefficient represents the average change of y-variable per unit increase of the dependent variable
Since the coefficients of x1 in both equations are positive, then that represents an increment on the y variable.
So, the interpretation is:
y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second
Solving (b): Multicollinearity
This could be the cause because x1 and x2 are related and as a result, x2 could take a part of the coefficient of x2
