Answer:
229.41
Step-by-step explanation:
Well you need to multiply 11.3 times 4.5 per each triangle
Also you need to find the base which is a square
So 5.1 times 5.1 which is technically 5.1 squared. You add from there
EQUATION: 4(11.3 x 4.5) + 5.1 squared
You should get 229.41

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.

What is the probability of getting a vowel if you randomly pick a letter from the English alphabet?
Assume that each time a metal detector at an airport signals, there is a 25% chance that the cause is change in the passenger's pocket. During a given hour, 15 passengers are stopped because of a signal from the metal detector. a) Find the probability that at least 3 passengers will have been stopped due to change in their pockets. b) If 15 passengers are stopped by the detector, would it be unusual for none of these to have been stopped due to change in the pocket
Answer:
a) 0.7639 = 76.39% probability that at least 3 passengers will have been stopped due to change in their pockets.
b) 0 is less than 2.5 standard deviations from the mean, so it would not be unusual.
Step-by-step explanation:
For each passenger, there are only two possible outcomes. Either they will have been stopped due to a change in the pocket, or not. Passengers are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
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]
A measure is considered unusual if it is more than 2.5 standard deviations of the mean.
25% chance that the cause is change in the passenger's pocket.
This means that [tex]p = 0.25[/tex]
During a given hour, 15 passengers are stopped because of a signal from the metal detector.
This means that [tex]n = 15[/tex]
a) Find the probability that at least 3 passengers will have been stopped due to change in their pockets.
This is
[tex]P(X \geq 3) = 1 - P(X < 3)[/tex]
In which
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{15,0}.(0.25)^{0}.(0.75)^{15} = 0.0134[/tex]
[tex]P(X = 1) = C_{15,1}.(0.25)^{1}.(0.75)^{14} = 0.0668[/tex]
[tex]P(X = 2) = C_{15,2}.(0.25)^{2}.(0.75)^{13} = 0.1559[/tex]
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0134 + 0.0668 + 0.1559 = 0.2361[/tex]
[tex]P(X \geq 3) = 1 - P(X < 3) = 1 - 0.2361 = 0.7639[/tex]
0.7639 = 76.39% probability that at least 3 passengers will have been stopped due to change in their pockets.
b) If 15 passengers are stopped by the detector, would it be unusual for none of these to have been stopped due to change in the pocket
First we find the mean and the standard deviation:
[tex]E(X) = np = 15*0.25 = 3.75[/tex]
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{15*0.25*0.75} = 1.68[/tex]
3.75 - 2.5*1.68 = -0.45
0 is less than 2.5 standard deviations from the mean, so it would not be unusual.

Answer:
y = 3/4x -2
Step-by-step explanation:
Points on the graph: (4, 1) and (0, -2)
Slope:
m=(y2-y1)/(x2-x1)
m= (-2-1)/0-4)
m=(-3)/(-4)
m = 3/4
Point-slope:
y - y1 = m(x - x1)
y - 1 = 3/4(x - 4)
y - 1 = 3/4x - 3
y = 3/4x -2
What is the average weight of the kittens in the shelter?
Please explain!!
Answer:
Step-by-step explanation:
You should add the weights of each kitten and then divide by the number of kittens. Ex. There are 5 kittens weighing 2, 1, 3, 2, and 2. So you would add those to get 10 and divide by the number of kittens which is 5 to get an average of 2.
So in this case you would first add the weight of the kittens
Then divide that by the number of kittens
Then the quotient would be the average of the weight of the kittens in the shelter.

A water tower 30 m tall is located at the top of a hill. From a distance of D = 125 m down the hill, it is observed that the angle formed between the top and base of the tower is 8°. Find the angle of inclination of the hill. Round your answer to the nearest tenth degree.
Answer:
the angle of inclination of the hill is 46.56°
Step-by-step explanation:
Given the data in the question;
Just as illustrated in the diagram below
so to find the angle of inclination of the hill;
sinA/30 = sinB/125
since angle BAC is 8°
we substitute
sin8°/30 = sinB/125
sinB = ( sin8°/30 ) × 125
B = sin⁻¹ ( ( sin8°/30 ) × 125 )
B = sin⁻¹ ( 0.004639 × 125 )
B = 35.44°
so since the some of a the angles of a triangle is 180;
A + B + C = 180
8° + 35.44° + C = 180
C = 180 - ( 8° + 35.44° )
C = 136.56°
Hence, Angle of inclination x will be;
x = 136.56° - 90°
x = 46.56°
Therefore, the angle of inclination of the hill is 46.56°

Maya obtains a $423,000 30/10 balloon mortgage with a rate of 5.65%. What will her monthly payments be? (2 points)
Answer:
Her monthly payment is approximately $4,611.65
Step-by-step explanation:
The monthly payment on the loan is given by the following formula;
[tex]A = P \cdot \dfrac{r\cdot (1 + r)^n}{(1 + r)^n - 1}[/tex]
A = The monthly payment
P = The principal amount = $423,000
r = 5.65%
The number of years = 10 years
[tex]A = 423,000 \cdot \dfrac{\dfrac{0.0565}{12} \cdot \left (1 + \dfrac{0.0565}{12} \right )^{180}}{\left (1 + \dfrac{0.0565}{12} \right )^{180} - 1} \approx 4611.65[/tex]
Her monthly payment, A ≈ $4,611.65
