Answer 1

Answer:

Step-by-step explanation:

Hey There!

So the first thing that we want to do is find the formula for volume of a pyramid

[tex]V=\frac{lwh}{3}[/tex]

l = length

w = width

h = height this is a square pyramid so if the length is 8 then the width is 8

So all we have to do now knowing the formula is plug in the values

[tex]V=\frac{8*8*9}{3} \\8*8=64\\V=\frac{64*9}{3} \\64*9=576\\V=\frac{576}{3} \\\frac{576}{3} =192\\[/tex]

So we can conclude that the volume of the square pyramid is 192

hope this helps :)

Answer 2

Answer:

198

Step-by-step explanation:

V= a^2 h/3 = 8^2 x 9/3 = 192

Volume = The base edge squared multiplied by the height divided by three. Which would convert to-

Volume = 8^2 x 9/3 = 192

Marcy sees a game, Rolling-in-gold, in which a constant rolls in a cube with five red sides one gold side. A player wins the game by rolling a gold. Is rolling-in-gold a fair game? If not, how could the game be made fair? Explain

Answers

Answer:

It's not fair, because it's only a 1 in 6 chance of rolling gold. It would be fair if 3 of the 6 sides were gold.

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.

Answers

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°

First number is the answer

Answer:

a.) 3x+2y=34 is the equation. 2 pairs could be 10,2 and 8,5.

b.) .5x+2y=14

c.) 8,5

Step-by-step explanation:

because both 8 and 5 work in both equations 3(8)+2(5)=34

.5(8)+2(5)=14

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?

Answers

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.
