Determine the radius of a circle with centre (0,0) that passes through (8,15)?

1 answer:

5 0

First, you need to set up the equation (0-8)^2 + (0-15)^2 = r^2. then solve for r and square root it. basically, you are using the distance formula to find the length from the center to the end of the circle or the radius.

Greeley [361]

Answer:

120

Step-by-step explanation:

There are 5 ways to choose the first position, 4 ways to choose the second and so on until we get only 1 way to choose the last position, therefore the answer is 5! = 5 * 4 * 3 * 2 * 1 = 120 ways.

write a word problem that you can represent with the expression 8÷2/3. draw a model and use equation to show the solution

Mariana [72]

Answer:

The word problem is " In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there".

Step-by-step explanation:

The given expression is

$8\div \frac{2}{3}$

We need write a word problem which is solved by the above expression.

Word problem : In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there.

Solution:

Let the total number student be x.

$x\times \frac{2}{3}=8$

Divide both sides by 2/3.

$x=\dfrac{8}{\frac{2}{3}}$

$x=\dfrac{8\times 3}{2}$

$x=12$

Therefore, the total number of students is 12.

Answer:

P (A and B)=8/9

Events A and B are not dependent.

Step-by-step explanation:

Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.

The events are independent (not dependent) because choosing A does not affect choosing B.
