Answer:
0.2
Step-by-step explanation:
6+4+3+2=total no of marble
=15
no of blue marble 3
[tex] \frac{3}{15} \\ = \frac{1}{5 } \\ = 0.2[/tex]
The probability that the marble is blue is 1/5 or 0.2.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Red marbles= 6
Green marbles = 4
Blue marble = 3
Yellow marbles= 2
Total marbles= 15
So, the probability getting blue marble
= blue marble / total marble
= 3/15
= 1/5

What is the average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2?
The average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2 is -5.
To find the average rate of change of a function over an interval, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the x-values.
The given function is f(x) = 2x^2 - x - 4.
Let's calculate the function values at the endpoints of the interval: -4 and 2.
For x = -4:
f(-4) = 2(-4)^2 - (-4) - 4 = 32 + 4 - 4 = 32.
For x = 2:
f(2) = 2(2)^2 - 2 - 4 = 8 - 2 - 4 = 2.
Now, we can calculate the difference in the function values: f(2) - f(-4) = 2 - 32 = -30.
Next, we calculate the difference in the x-values: 2 - (-4) = 6.
Finally, we can calculate the average rate of change by dividing the difference in the function values by the difference in the x-values:
Average Rate of Change = (f(2) - f(-4)) / (2 - (-4)) = -30 / 6 = -5.

Answer:
1. Not similar
2. Similar, ABC is similar to FED by SSS
Step-by-step explanation:
1. Not similar.
The interior angles of a triangle always have to add up to 180, and since the first triangle has angles 30 degrees and 90 degrees, you know the third angle will have to be 180 - 30 - 90 = 60 degrees.
The second triangle's third angle will have to be 50 degrees because 180 - 90 - 40 = 50 degrees.
Since the three angles of the triangle are not the same, they are not similar.
2. Similar, ABC is similar to FED by the SSS triangle similarity postulate.
First, AB is similar to FE because AB = 15 and FE = 5, so the scale factor is 3
Next, BC is similar to ED because BC = 9 and ED = 3, so the scale factor for these sides is also 3
Lastly, CA is similar to DF because CA = 12 and DF = 4, so the scal factor for this is also 3.
Since the scale factor for all of the sides is 3, these two triangles are similar.

Gethyn drinks 48 fluid ounces of water in one day. He needs to drink 8 cups in total. How many more cups does he need to drink?
A) 2 cups
B) 6 cups
C) 384 cups
D) 768 cups
Answer:A
Step-by-step explanation:1 cup is equal to 8 fluid ounces so 48/8=6 and since he needs to drink 8 cups of water the answer is 2 more.
The number of cups of water Gethyn need to drink more is 2 cups. Therefore, option A is the correct answer.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Given that, Gethyn drinks 48 fluid ounces of water in one day.
We know that, 1 ounce = 0.125 cups
Here, 48 fluid ounces = 48×0.125
= 6 cups
Number of cups of fluid = 8-6
= 2 cups
Therefore, option A is the correct answer.

Multiple choice answer
Answer:
C. 9.24
Step-by-step explanation:
x is the height here, looking at the triangle.
To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.
6/cos(57) would equal about 11.0647.
Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.
x = √11.01647² - 6²
x = √121.3626112609 - 36
x = √85.3626112609
x = 9.23918888544335
x ≈ 9.24, so C is the answer.
