Answer:

F, spinning a spinner with five equal sections

Step-by-step explanation:

The probability of something is (the ways to acheive the wanted outcome / all possible situations)

For example, the probability of getting heads on a coin flip is (1 possible way to get heads / 2 possible outcomes) = 1/2, or 50/50

Now, onto the problem.

There is only one way to get the answer right, and 5 possible situations. So, the probability of getting the question right would be 1/5.

F) Spinning a spinner with five parts means that you have: 1 way to get the right section, and 5 possible outcomes. So, the probability of getting the right section would be 1/5. So, this answer is correct.

G) Flipping a coin five times: Each time, you have a 1/2 chance of the coin landing on the desired side. So, this would not be an accurate comparison.

H) Spinning a spinner with four equal sections: There is one way to land on the desired section, and 4 possible outcomes. So, the probability of this simulation is 1/4, so this answer is incorrect.

I) Rolling a number cube labeled one through six times: Each time, there is one way to land on the number you want, while there are six possible outcomes. So, the probability of getting your desired number is 1/6, which is incorrect.

I hope this helps! Feel free to ask any questions!

What is the length of the unknown leg in the right triangle?
Rama09 [41]

Answer:

we will use Pythagorean's Theorem

25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15

Therefore, the missing leg is  15 meters long.

Step-by-step explanation:

we will use pythagoras theorem

Given that,

One leg of the triangle is 20 meters long,

the hypothenuse is 25 meters long,

and the leg missing is called x.

we will use Pythagorean's Theorem

25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15

Therefore, the missing leg is  15 meters long.

The sum of 2 numbers is 52. Express the product of the numbers, P, as a function of one of the numbers, x.
kolezko [41]

Answer:

The sum of 2 numbers is 52. Express the product of the numbers, P, as a function of one of the numbers, x.

the answer is p(x) = -x² + 52x

Step-by-step explanation:

let the  two numbers be x and y

the  sum of the two numbers = x + y

≡ x + y = 52

make y the subject of equation

y= 52 - x

to express the product of the numbers, P, as a function of one of the numbers, x. implies that

P(x) = x(-x + 52)

finally,

p(x) = -x² + 52x

Mrs.Evans has 13 pictures to hang on a wall.Is there any way she can arrange the pictures other than 1x13 13x1 so that she can h
Drupady [299]

Answer:

Step-by-step explanation:

A prime number is a positive integer that only has a factor of one and itself. Factors are the numbers we multiply together to get another number.

Example: 11 is a prime number. To get 11, we can only multiply 1x11.

A composite number is a positive integer that has factors other than one and itself.

Example: 12 is a composite number. To get 12, you can multiply together 1x12, 2x6, and 3x4. 1, 2, 3, 4, 6, and 12 are all factors of 12.

In the problem you are trying to solve, Mrs. Evans wants to hang 13 pictures with the same number of pictures in each row. Find all of the factors of 13: 1, 13. Those are the only numbers we can multiply together to get 13. Since its factors are only 1 and itself, 13 is a prime number. Because 13 is a prime number, there are no other possible ways she can arrange her pictures into rows with the same number of pictures in each.
