A market researcher, having collected data on breakfast cereal expenditures by families with one, two, three, four, or five children living at home, plans to use an ordinary regression model to estimate the mean expenditures at each of these five family size levels. However, the researcher is undecided between fitting a linear or a quadratic regression model, and the data do not give clear evidence in favor of one model or the other. A colleague suggests: "For your purposes, you might simply use an ANOVA model." Is this a useful suggestion? Explain.
Answers
Answer:
Yes it is a useful suggestion
Step-by-step explanation:
Using the ANOVA model is a good idea because using it would give allowance For us to compare the five means of the five different family sizes. By this, during investigation there would be no confusion as to if a quadratic or linear relationship exists between the variables family size and breakfast cereal expenditure.
We would be comparing the mean expenditure of food of these 5 different family size levels so anova is useful.
Answer and Step-by-step explanation:
ANOVA model is mathematical model describe relationship between response and treatment.
One way ANOVA is given by:
YIJ = µ + Ti +Єij
Where, yij represent jth observation on ith treatment.
In this question, researcher collected data on the breakfast expenditure of a family whose size is five.
Yes, we can use ANOVA model. ANOVA can be used even if there is quadratic nonlinear relationship between expenditure and family size.
Since, the family size is five; we have to compare their mean expenditure on food.
The ANOVA one way model is:
YIJ = µ + Ti +Єij
For i=1, 2,3,4,5 and j= 1, 2,3,4,5
With hypothesis,
H01 : µ1 are equal.
H11 : at least two i not equal to j.

x = 23
DBC = 23
ABC = 157
Step-by-step explanation:
angles ABC and CBD are supplementary.
supplementary angles add up to 180.
you can make the following equation
6x + 19 + x = 180
7x + 19 = 180
7x = 180 - 19
7x = 161
x = 161/7
x = 23
substitute x into the equations
DBC = x
DBC = 23
ABC = 6x + 19
ABC = 6 * 32 + 19
ABC = 138 + 19
ABC = 157

Show how to solve the following; answer must be with fractions and pi
theta=tan^-1(-6/6)
I can get the decimal form from calculator, but I require the fractional answer and I need to know how it even gets obtained. How do we know what inverse tan of -6/6 will = to?
Answers
Answer:
3pi/4 and -pi/4
Step-by-step explanation:
We can simplify -6/6 to -1.
Therefore, this function can be simplified to arctan(-1).
Recall that the meaning of arctan is to find a value that will get the value inside the parenthesis when taken the tangent of it. In other words, tan(x) = -1.
Recall that tan(x) = sin(x)/cos(x). Now recall that sin(pi/4) and cos(pi/4) are both sqrt(2)/2, meaning that tan(pi/4) is 1. To make it -1, we can either make sin(x) -1 while keeping cos(x) 1, or the other way around.
If x is -pi/4, cos(x) will still be 1, but sin(x) will be -1, so tan(-pi/4) will be -1.
If x is 3pi/4, cos(x) will be -1, but sin(x) will still be 1, so tan(3pi/4) will be -1.
Side note: there are still infinite more answers. You can attain them by adding or subtracting 2pi as many times as you want from 3pi/4 or -pi/4 and still get an arctan of -1.

What has kept you from saving in the past?
Answers
A Potential Answer:
One thing that has kept me from saving in the past is my confusion of my "wants" and "needs". An outcome of this is me constantly spending money on things that aren't necessary instead of buying things that are useful. An example of this is when I went to the store and decided to buy expensive band merchandise, as well as my groceries. If I hadn't bought the band merchandise, I could have saved $30. To fix this, I started to work on my self-control and budget management.

Step-by-step explanation:
Any scientific or graphing calculator can evaluate this expression for you.
__
When adding numbers in scientific notation, they need to have the same multiplier exponent. Here, it is convenient to use 10^6:
8.0×10^5 = 0.8×10^6
6.0×10^7 = 60×10^6
Then the sum is ...
(0.8 +60)×10^6 = 60.8×10^6 = 60,800,000
. A 0.660 kg ball is dropped from rest from the top of a building and falls for
5.65 seconds. How tall was the building? [Neglect friction. Assume on or near
the Earth's surface.]
Answers
Answer:
The height of the building is 156.42 m
Step-by-step explanation:
Given;
mass of the ball, m = 0.66 kg
time of fall, t = 5.65 s
initial velocity of the ball, u = 0
Apply the following kinematic equation to determine the height of the building;
h = ut + ¹/₂gt²
h = ¹/₂gt²
h = ¹/₂ x 9.8 x 5.65²
h = 156.42 m
Therefore, the height of the building is 156.42 m
The building was 156.42 metres tall
From the question we are told that
the mass of the ball, m = 0.66 kg
the time of fall, t = 5.65 s
the initial velocity of the ball, u = 0
If we use one of the equations of motions in
h = ut + ¹/₂gt², we then have
h = (0 * t) + (0.5 * 9.8 * 5.65²)
h = 4.9 * 31.923
h = 156.42 m
The height of the building is 156.42 m

Find the value of x - The answer is 45, but I need to show my work!!!
THANK YOU
Answers
Answer:
x = 45°
Step-by-step explanation:
The total measurement is 360° (the measurement of a circle).
Set the equation. Set all measurements equal to 360:
228 + (x + 29) + (x + 13) = 360
Combine like terms:
228 + 29 + 13 + 2x = 360
2x + 270 = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to other. Do the opposite of PEMDAS. First, subtract 270 from both sides:
2x + 270 (-270) = 360 (-270)
2x = 360 - 270
2x = 90
Next, divide 2 from both sides of the equation:
(2x)/2 = (90)/2
x = 90/2
x = 45
x = 45° is your answer.

90 degrees minus 18 is 72, 72 divided by 9 is 8. Making 8 equal to x. 9x +18 ((9)8 + 18) is equal to 90 degrees.
