The volume of a pyramid is:

V = (length * width * height of pyramid)/3

Note that:

length = 8

width = 8

height of the pyramid = 3

height of the triangle = 5

Solve for Volume:

Multiply

V = (8 * 8 * 3)/3

V = (192)/3

Divide

V = (192)/3

V = 64

A. 64 yd³ is your answer

Jezebel is planning a party at the skating rink. The cost for each person attending is $3.50 for skate rental and $5.00 for food

SashulF [63]

Answer:

The inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

Step-by-step explanation:

From the information provided, you can write an inequality where total cost for people attending at the party should be less than or equal to $300:

3.50p+5.00p≤300

8.50p≤300

Now, you can solve for p:

p≤300/8.50

p≤35

According to this, the answer is that the inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

Describe each of the following values as (A) a discrete random variable, (B) a continuous random variable, or (C) not a random v

Lyrx [107]

Answer:

(1) B

(2) A

(3) C

Step-by-step explanation:

A random variable is a variable that denotes a set of all the possible outcomes of a random experiment. It is denotes by a single capital letter such as X or Y.

There are two types of random variables.

Discrete random variable: These type of random variable takes finite number of values, such as 0, 1, 2, 3, 4, ... For example, number of girl child in a neighborhood.
Continuous random variable: These type of random variables takes infinite number of possible values. For example, the height, weight.

(1)

Exact weight of quarters now in circulation in the United States.

The variable weight is a continuous variable.

Thus, the exact weight of quarters now in circulation in the United States is a continuous random variable.

(2)

Shoe sizes of humans.

The shoe size of a person are discrete and finite values.

Thus, the shoe sizes of humans are discrete random variables.

(3)

Political party affiliations of adults in the United States.

This variable is not a quantitative variable.

It is a qualitative variable.

Thus, the political party affiliations of adults in the United States is no random variable.

A case in riverhead, new york, nine different crime victims listened to voice recordings of five different men. all nine victims

Alexus [3.1K]

the complete question in the attached figure

1) Find the probability that all nine victims would select the same person. You should enter your answer as a decimal, not as a percent. Do not round, as your answer should be a terminating decimal.

P=(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)=0.000000512

2) what is the probability that the first victim picks SOMEONE? ANYONE?

P=(1/5)=0.20 ---------------- > 20%

3) Now let’s look at victim #2. What is the probability that they pick the same person as victim #1?

P=(1/5)*(1/5)=0.04 --------------> 4%

4) Now let’s look at victim #3. What is the probability that they pick the same person as victim #1?

P=(1/5)*(1/5)*(1/5)=0.008 --------------> 0.8%

5) Now let's look at victim #9. What is the probability that they pick the same person as victim #1?

P=(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)*(1/5)=0.000000512

6) Once you find all those probabilities, what rule would apply?

the probability is given by (1/5)^n

n=number of victims that pick the same person---------> in this problem = 9

P=(1/5)^9= 0.000000512
