Answers
Answer:
Table A.
Step-by-step explanation:
$139.50 / 6 hours = $23.25 an hour
1 hour of work = $23.25 earned
(now add $23.25 for the next hour of work)
2 hours of work = $46.50 earned
(now add $23.25 for the next hour of work)
3 hours of work = $69.75
(now add $23.25 for the next hour of work)
4 hours of work = $93 earned
(now add $23.25 for the next hour of work)
5 hours of work = $116.25 earned
(now add $23.25 for the next hour of work)
6 hours of work = $139.50 earned
(now add $23.25 for the next hour of work)
7 hours of work = $162.75 earned
(now add $23.25 for the next hour of work)
8 hours of work = $186 earned
(now add $23.25 for the next hour of work)
9 hours of work = $209.25
(now add $23.25 for the next hour of work)
10 hours of work = $232.50
and continued on...

Answers
Answer:
8
Step-by-step explanation:
We know that ABD is 30 degrees. To find BC, we need to use sin.
Equation:
BC = 16*sin(30 degrees) I recommend using a calculator to find the sine if you don't know what it means and how to use it. Sine is basically the side length opposite of the angle over the hypotenuse of the right triangle.
BC = 16*0.5
BC = 8

A team of communication scholars conducted a study on the effects of media consumption on aggressive behavior. Forty-eight subjects stayed in a lab for two days. Twenty-four of the subjects are randomly assigned to a condition in which they are not permitted to consume any media that period. The other twenty-four are allowed to consume media whenever they want. At the end of the two days, the subjects finish a task that involves viewing the same tv episode, then identifying as many aggressive behaviors as possible.
For each of the studies, please indicate the following:
1. What is the independent variable? The effects of media consumption
2. Is there more than one IV? Abstinence from Media Consumption and Media Consumption Continued Use
3. Is the IV a continuous or categorical variable? See Above
4. What is the dependent variable? (for correlation, list all variables here and ignore the IV questions)
~ The dependent variable is aggressive behavior
5. Is the DV a continuous or categorical variable ? Continuous ~ measured numerically, has an infinite number of possible values
6. What type of design is being used? Experimental Design
7. What is the appropriate statistical test given the types of variables in this example?

Answer:
A.) The Independent variable is media consumption. ;
B.)
1.) Abstinence from media consumption
11.) Continued consumption of media
C.)
Categorical Variable ;
D.)
Dependent variable is Aggressive behavior ;
E.)
The dependent variable is a continous numerical variable
F.)
Experimental Design.
Step-by-step explanation:
The Independent variable are those variables which causes a change in the measured or dependent variable.
The dependent t variable is the measured variable whose change is triggered by the independent variable.
Categorical Variables are non-numeric labels while the quantitative variables are numeric labels.
Experimental designs usually divides subjects into two or more treatment groups whrebt the effects of applied treatment is observed across the different groups.

Answers
Answer:
After 4 years working for the company, he would make $79,000 of salary.
His salary after t years will be:

Step-by-step explanation:
David just accepted a job at a new company where he will make an annual salary of $69000. David was told that for each year he stays with the company, he will be given a salary raise of $2500.
This means that after t years, his salary will be given by:

How much would David make as a salary after 4 years working for the company?
[te]S(4) = 69000 + 2500*4 = 69000 + 10000 = 79000[/tex]
After 4 years working for the company, he would make $79,000 of salary.

The function that best models for the data is y = -200 (x-4)^2 + 800.
What is a function?A function is a mathematical expression that describes how factors are related. In this case, how the price is related to the profit.
How to determine if a function models the data?The best way to determine this is to solve the expression and verify if the answer is correct.
For example, we know that at 4 (x) dollars, the daily profit is $800 (y). Let's now the different options:
A.
y= -8 (x+4)^2 + 800y= -8 (4+4)^2 + 800y= -8 (8)^2 + 800y= -8 (36) + 800y=-8 (288) + 800y= -2304 + 800y= -1504B.
y= -8 (x-4)^2 + 800y= -8 (4-4)^2 + 800y= -8 (0)^2 + 800y= -8 (0) + 800y= 0 + 800y= 800C.
y= -200 (4+4)^2+ 800y= -200 (8)^2 + 800y= -200 (36) + 800y= -200 (36) + 800y= -7200 + 800y= -6400D.
y= -200 (x-4)^2 + 800y= -200 (4-4)^2 + 800y= -200 (0)^2 + 800y= -200 (0) + 800y= 0 + 800y= 800This means B and D are possible options, however, when verified with other results such as $6 the correct one is option D.

The quadratic equation is given by y = -200x² + 1600x - 2400.
Quadratic equation formulaThe standard form of the quadratic equation is:
y = ax² + bx + c
Where a,b,c are constants.
Let y represent the daily profit for x bread price.
At point (2, 0):
0 = a(2)² + b(2) + c
4a + 2b + c = 0 (1)
At point (4, 800):
800 = a(4)² + b(4) + c
16a + 4b + c = 800 (2)
At point (6, 0):
0 = a(6)² + b(6) + c
36a + 6b + c = 0 (3)
From all the equations:
a = -200, b = 1600, c = -2400

Answers
Answer:
6.4Step-by-step explanation:
Given scores:
15, 25, 10, 2, and 8Mean of the scores:
(15 + 25 + 10 + 2 + 8)/5 = 12Absolute deviations:
|15 - 12|= 3|25 - 12|= 13|10 - 12| = 2 |2 - 12| = 10|8 - 12| = 4Sum of absolute deviations:
3 + 13 + 2 + 10 + 4 = 32Mean absolute deviation:
32/5 = 6.4total no of game (n)=5
score =15, 25, 10, 2, and 8 points
mean= sum of score/no.of game
=(15+25+10+2+8)/5=60/5=12
absolute deviation of
15=\15-12\=3
25=\25-12\=13
10=\10-12\=2
2=\2-12\=10
8=\8-12\=4

3. People with type O-negative blood are universal donors (any patient can
receive a transfusion of O-negative blood). Only about 6.6% of the American
population has O-negative blood. If 270 unrelated people give blood in a certain
week, how many of these people do we expect to be universal donors? (Hint:
Remember to convert percent numbers to decimals before multiplying.)
PLEASE HELP
Answers
Answer:
We expect 17.82, that is, approximately 18 people to be universal donors.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are universal donors, or they are not. The probability of a person being an universal donor is independent of any other person. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Only about 6.6% of the American population has O-negative blood.
This means that [tex]p = 0.066[/tex]
If 270 unrelated people give blood in a certain week, how many of these people do we expect to be universal donors?
This is E(X) when [tex]n = 270[/tex]. So
[tex]E(X) = np = 270*0.066 = 17.82[/tex]
We expect 17.82, that is, approximately 18 people to be universal donors.
