Which equation combines with the given equation to form a system of equations with the solution x = 3 and y = 9? x + 2y = 21

max2010maxim [7]

Yes. x=3 and y =9 are the solutions.
Because if you change x=3 and y =9 ,you will have
3+2* 9 =21
3+18 =21
21 =21 (true)

Based on a study from the Chronicles of Flippin'' Awesomeness, the probability that Napoleon and Pedro make it to their first pe

muminat

Answer:

15.25% probability that Napoleon and Pedro catch the bus and make it to their first period class on time

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that:

Event A: Both Napoleon and Pedro catch the bus, so P(A) = 0.25.

Event B: Making to their first period class on time.

However, the probability that they make it to their first period class on time, given that they catch the bus is 0.61.

This means that $P(B|A) = 0.61$

What is the probability that Napoleon and Pedro catch the bus and make it to their first period class on time

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$0.61 = \frac{P(A \cap B)}{0.25}$

$P(A \cap B) = 0.61*0.25$

$P(A \cap B) = 0.1525$

15.25% probability that Napoleon and Pedro catch the bus and make it to their first period class on time

VikaD [51]

Answer:

Their headquarters contains <u>420000</u> employees.

Step-by-step explanation:

The company has two office buildings which hold 30,000 employees.

The headquarters contains 14 times as many employees as the overseas branch.

Therefore, the number of employees in the headquarters is:

14 * 30000 = 420000 employees

Their headquarters contains 420000 employees.

Archimedes (ca. 287-212 B.C.) was able to use clever geometric means to determine the relative volumes of a cylinder and the con

VLD [36.1K]

Answer:

The ration of the volume of cone to that of cylinder is $\frac{V_{cone}}{V_{cy}} = \frac{1}{3}$

Step-by-step explanation:

From the question we are told that

The volume of a cone is mathematically represented as

$V_{cone} = \frac{1}{3} \pi r^2 h$

The volume of a cylinder is mathematically represented as

$V_{cy} = \pi r^2 h$

Now the ratio we are to obtain is

$\frac{V_{cone}}{V_{cy}} = \frac{\frac{1}{3} \pi r^2 h}{\pi r^2 h}$

$\frac{V_{cone}}{V_{cy}} = \frac{\frac{1}{3} }{1}$ Note: this is possible because the height and base

$\frac{V_{cone}}{V_{cy}} = \frac{1}{3}$ radius are the same

5 Show different ways to make 492,623.

timama [110]

Step-by-step explanation:

Start by writing 492,623 in standard form

4 hundred thousands + 9 ten thousands + 2 thousands + 6 hundreds + 2 tens + 3 ones

We can write this in other ways by moving a digit to the next smaller place value. For example, we move the 4 one place to the right to get 49 ten thousands:

49 ten thousands + 2 thousands + 6 hundreds + 2 tens + 3 ones

Then, we can move the 49 ten thousands to the right to get 492 thousands, and we can move 6 hundreds to the right to get 62 tens.

492 thousands + 62 tens + 3 ones

Or, we can do this:

4926 hundreds + 23 ones
