A bag has 15 marbles—5 blue, 8 green, and 2 red. One marble is drawn from the bag and then replaced, and this action is repeated 20 times. The results are recorded in the table. What is the experimental probability in the simplest form of selecting a blue marble from the bag?
A. 1/20
B. 7/20
C. 1/3
D. 3/5
Answers
Answer
its either b or d
Step-by-step explanation:
The experimental probability of selecting a blue marble from the bag is 7/20.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The experimental probability of selecting a blue marble from the bag is given by the number of times a blue marble was selected divided by the total number of selections.
According to the table, a blue marble was selected 7 times out of a total of 20 selections, with replacement.
Therefore, the experimental probability of selecting a blue marble is:
7/20
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1.
7/20
Hence, the experimental probability of selecting a blue marble from the bag is 7/20.

Which function has a greater rate of change? Explain. (2 points total, correct rate of change
Answers
To find the rate of change for function A, you have to divide the value of y by the value of x, and when you do that, you get about 4.55 and Function B already has the rate of change because in the equation, the rate of change is going to be multiplied by the value of x, so the rate of change is -4.5. 4.55 is greater than -4.5 so function A has a greater rate of change

A right triangle has a leg length of 10 meters and a hypotenuse that is 26 meters. What is the length of the other leg?
Answers
Answer:
The length of the other leg is 24 meters.
Step-by-step explanation:
Well, let's think about the equation that gives us the hypotenuse in the first place, the Pythagorean theorem (which only works on right triangles!).
[tex]a^2+b^2=c^2[/tex]
The a^2 is one side of the triangle that we know and the b^2 is the other, the c^2 is the hypotenuse we are trying to solve.
Seeing that in this question, we can put 10, in the place of a^2, and 26 in the place of c^2
[tex]10^2+b^2=26^2[/tex]
That's what we have down the information we have, but now we'll have to do some rearranging to solve for the other leg's length. First let's square the numbers, 10^2 = 100 and 26^2= 676!
[tex]100+b^2=676[/tex]
Now we need to get b^2 by itself so we can solve it! Let's subtract 100 from both sides to do so,
[tex]100-100+b^2=676-100[/tex]
[tex]b^2=676-100[/tex]
[tex]b^2=576[/tex]
Now we got b^2 = 576!
But that's not our answer we have to square root it to get rid of the squared part!
[tex]\sqrt{b^2} = \sqrt{576}[/tex]
and when we do that we get,
[tex]b=24[/tex]
The length of the other leg is 24 meters!
The length of the other leg is 24 m.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
A right triangle has a leg length of 10 meters and a hypotenuse that is
26 meters.
The length of the other leg = x
We will apply the Pythagorean theorem.
x² + 10² = 26²
x² + 100 = 676
x² = 676 - 100
x² = 576
x = 24
Thus,
The length of the other leg is 24 m.
