Answer and Step-by-step explanation:
This regression can generate an omitted variable bias, because the researcher did not determine any parameters or real data to measure it. In this case, the researcher determined the crime rate as a dependent variable, but did not establish the facts that influence it and that promote an observable result. In this way, he omitted the independent variable and his research will be inaccurate and incorrect. To control this bias, it is necessary for the researcher to provide a dependent variable such as the level of education in the region, the income distribution in the region, the unemployment rate, the fraction of young men, among others.

A basketball player completed 44.2% of his field goals in the most recent season. He made 287 field goals. How many did he attempt?
44.2%= 287
Let the total attempt = x
(287/x) ×100 = 44.2
287/x = 44.2/100
287/x = 0.442
x = 287/0.442
x= 649Hope this will help...
A question asks: How many hours per week do you watch television? The respondent can answer in minutes and/or hours. What would be the best numerical summary of data from 300 participants? A. Mean, standard deviation, and range B. Median, IQR, and range C. Number and percent of total for each response option D. A or B depending on the distribution of the sample E. B and C
Answer: D. A or B depending on the distribution of the sample
Step-by-step explanation:
Given: A question ask about how many hours per week do you watch television?
Total participants = 300
Since all participants are different , so have their own answer to this question in numerical terms.
We use proportion or percentage to summarize data if data is categorical, but here data is numerical (continuous).
here , we can use either mean or median ( if it has outliers).
For this we need to check the distribution of the data, if it is normal then Mean, standard deviation, and range would be a better option (as mean is the best measure of tendency)otherwise Median, IQR, and range would be a better option .
hence, the correct option is D. A or B depending on the distribution of the sample

A rational number will either end or repeat forever like the first three, but the fourth one, pi, will go on forever and never repeat, making it irrational.
If a club charges dues of $200 a year, it will have 50 members. For each $5 it raises its dues, it loses a member. USE AN EQUATION to determine what the club should charge to maximize its income from dues.
Answer:
The value is [tex]y = \$ 225[/tex]
Step-by-step explanation:
From the question we are told that
The amount charge per year is [tex]k = \$ 200[/tex]
The number of members it will have at this amount is [tex]n = 50[/tex]
The amount amount increase that will lead to the loss of a single member is [tex]z = \$ 5[/tex]
Generally the total amount the club would obtain from its members is mathematically represented as
[tex]I = Amount \ due\ paid * Number \ of members[/tex]
Now let x denote the number of member lost
Hence
[tex]I = (k + zx) (n-x )[/tex]
=> [tex]I = (200 + 5x) (50-x )[/tex]
=> [tex]I = 10000+50x-5x^2[/tex]
Thus the number of members that be removed to give the maximum income from dues is obtained by differentiating the above equation and equating it to zero
[tex]\frac{dI}{dx} = 50-10x[/tex]
=> [tex] x = 5[/tex]
So from [tex]I = (200 + 5x) (50-x )[/tex] we have
[tex]I = (200 + 5 (5)) (50-5 )[/tex]
[tex]I = \$ 10125 [/tex]
So the amount the club should charge is
[tex]y = \frac{10125}{50 - 5}[/tex]
[tex]y = \$ 225[/tex]

Step-by-step explanation:
A standard number cube is rolled. Calculate: P(rolling 1 or 3)
Answer:
the probability is:
P(A) 2/6 =1/3
Now let's take rolling a prime number:
A prime number is a natural number greater than 1 which can only be divided without a remainder by 1 and itself. So from the numbers on the cube prime numbers are:
2, 3 and 5. The probability of getting a prime number in a single roll is:
P(B) =3/6=1/2
Now to calculate the probability of A and B
you have to multiply both probabilities:
P(A-B)=P(A) . P(B) = 1/3 . 1/2 = 1/6

Determine parallel, perpendicular, or neither!
What is the equation of the line that is parallel to y = 2/3x+ 4 and passes through
the point (-7, 1)?
Answer:
The answer is
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = ⅔x + 4
Comparing with the general equation above
Slope = 2/3
Since the lines are parallel their slope are also the same
Slope of parallel line = 2/3
Equation of the line using point (-7 , 1) and slope 2/3 is
[tex]y - 1 = \frac{2}{3} (x + 7) \\ y - 1 = \frac{2}{3} x + \frac{14}{3} \\ y = \frac{2}{3} x + \frac{14}{3} + 1[/tex]
We have the final answer as
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Hope this helps you

Hey there! I'm happy to help!
A is -10 and F is -5. To find the number in between two numbers, you add them and divide by 2.
-10+(-5)=10-5=-15
-15/2=-7.5
So, the midpoint is -7.5, which is right in between C and D.
