The roller coaster has a mass of 600 Kg speeds up to 22 m/s as it goes down a giant hill. Calculate the kinetic energy. SHOW WORK!

Answers

Answer 1

Answer:

145.2 kJ

Step-by-step explanation:

Kinetic Energy formula

K.E. = 1/2mv², where :m = massv = velocity

Substituting the given values

K.E. = 1/2 x 600 x (22)²K.E. = 300 x 484K.E. = 145200 JK.E. = 145.2 kJ
Answer 2

Answer:

145,200 J

Step-by-step explanation:

The formula to calculate kinetic energy is [tex]K=\frac{1}{2}mv^{2}[/tex], where K is the kinetic energy in Joules, m is the mass in kg, and v is the velocity in m/sSubstitute in the values[tex]K=\frac{1}{2}\times 600\times 22^{2}[/tex][tex]K=\frac{1}{2}\times 600\times 484[/tex][tex]K=\frac{1}{2}\times 290400[/tex][tex]K=145200[/tex]

Johnson cut a round pizza into 12 equal pieces. He ate 4 adjacent pieces. What is the measure of the angle of the pizza that Johnson ate?

A.
48°

B.
90°

C.
120°

D.
160°

Answers

The answer is C, because the angle is obtuse, but also not as big as 160°

Answer:

C 120 degrees

Step-by-step explanation: 3 times 4 equals 12 so if 4 peices are eaten then there is only 2/3 left so theres only 240 degrees left of the pizza so we take 360 minus 240 we get 120 so there is 120 degrees of pizza eaten by johnson.

This is easy....

First, the frequency is how many times a number or certain value in a set of data appears...

So basically, its asking you for the number of times that a number in between 0 and 9 appears in the data set:

23, 15, 18, 11, 30, 32, 47, 5, 9, 10, 0, 34, 39, 49, 9

To make this easier, we can put them in numerical order.

0,5,9,9,10,11,15,18,23,30,32,34,39,47,49

Now, just single out the numbers before 10.

0,5,9,9

4 numbers, so its 4. The number of times a number between 0 and 9 appears in the data set is 4. That goes in the Frequency side...

Find the formula for an inverse proportion, knowing that its graph goes through the point: A(8, 0.125) PLEASE EXPLAIN WELL! THANK YOU

Answers

The formula for the given inverse proportion is:

y = 1/x

How to get the formula of the inverse proportion?

The general formula of an inverse proportion is written as:

y = k/x

Where k is the constant of proportionality.

In this case, we know that the point (8, 0.125) belongs to the graph, then replacing these values on the general formula we get:

0.125 = k/8

Solving for k we get:

0.125*8 = k = 1

Then the inverse proportion is:

y = 1/x

The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 7% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. Assuming his suspicion that 7% of his customers buy a magazine is correct, what is the probability that exactly 4 out of the first 14 customers buy a magazine

Answers

Using the binomial distribution, it is found that there is a 0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.

What is the binomial distribution formula?

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.

In this problem:

7% of his customers buy a magazine, hence p = 0.07.A sample of 14 customers is taken, hence n = 14.

The probability that exactly 4 out of the first 14 customers buy a magazine is P(X = 4), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 4) = C_{14,4}.(0.07)^{4}.(0.93)^{10} = 0.0116[/tex]

0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.
