The probability of pulling a blue marble and the coin landing tails up is 360/2500
How to determine the probability?The tables of values are given as:
Color Times
Blue 18
Green 20
Yellow 12
Heads Tails
20 30
The probability of obtaining a blue marble is:
P(Blue) = 18/50
The probability of landing tails up is:
P(Tail) = 20/50
The required probability is:
P = P(Blue) * P(Tail)
This gives
P = 18/50 * 20/50
Evaluate the product
P = 360/2500
Hence, the probability of pulling a blue marble and the coin landing tails up is 360/2500

The table shows values of function f(x). The graph shows the function g(x).
What is the average rate of change of f(x) over the interval from x=2 to x=6?
Find the average rate of change of g(x) over the interval from x=0 to x=4.
What is the difference between the two functions? Which one is moving more quickly? What does it mean to have a negative answer?
The average rate of change for f(x) and g(x) are respectively 2.25 and -2 and so we can say that f(x) is moving more quickly.
How to find the average rate of Change?
Formula for the average rate of change is;
f'(x) = (f(b) - f(a))/(b - a)
Thus;
1) Average rate of change of f(x) over the interval from x = 2 to x = 6 is;
f'(x) = (f(6) - f(2))/(6 - 2)
We are given;
f(6) = 10 and f(2) = 1
Thus; f'(x) = (10 - 1)/4 = 2.25
2) Average rate of change of g(x) over the interval from x = 0 to x = 4 is;
g'(x) = (g(4) - g(0))/(4 - 0)
We are given;
g(4) = 0 and g(0) = 8
Thus; g'(x) = (0 - 8)/4 = -2
3) From the average rate of change of both functions, we see that f(x) is positive and has a higher rate of change and so we can say that f(x) is moving more quickly.

Given sine of x equals negative 5 over 13 and cos x > 0, what is the exact solution of cos 2x?
The value of cos 2x is 119/169 after applying the trigonometric identity cos2x = 1 - 2sin²x option second is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have given:
sinx = -5/13
and cosx > 0
We know,
cos2x = 1 - 2sin²x
sinx = -5/13
Squaring on both sides:
sin²x = 25/169
Multiply by 2 on both the sides:
2sin²x = 2(25/169)
Add -1 on both sides:
-1 + 2sin²x = -1 + 2(25/169)
or
1 - 2sin²x = 1 - 2(25/169)
cos2x = 1 - 50/169
cos2x = 119/169 (as the cosx > 0)
Thus, the value of cos 2x is 119/169 after applying the trigonometric identity cos2x = 1 - 2sin²x option second is correct.

factoring using the distributive property
got really sick and missed a bunch of school, would really appreciate the help !
Answer:
Step-by-step explanation:
Factorizing using distributive property: Factorize the terms Find the Greatest Common factor. Take GCF from both the terms.1) 5a² - 15
5a² = 5 * a²
15 = 5 * 3
GCF = 5
5a² - 15 = 5*a² - 5*3
= 5a(a - 3)
5) 36x²y - 48xy²
36x²y = 2 * 2 * 3 * 3 * x² * y
48xy² = 2 * 2 * 2 * 2 * 3 * x * y²
GCF = 2 * 2 * 3*x*y = 12xy
36x²y - 48xy² = (12xy * 3x) - (12xy*4y)
= 12xy*(3x - 4y)

GCF = 3*5*b*c³ = 15bc³

Which statement about events A and B is TRUE? A. If P(A | B) = P(B) and P(B | A) = P(A), then the events are dependent. B. If P(A | B) = P(B) and P(B | A) = P(A), then the events are independent. C. If P(A | B) = P(A) and P(B | A) = P(B), then the events are independent. D. If P(A | B) = P(A) and P(B | A) = P(B), then the events are dependent.
Using conditional probability, it is found that the correct statement is given by:
C. If P(A | B) = P(A) and P(B | A) = P(B), then the events are independent.
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:

In which:
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.If two events are independent, we have that:

Hence:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)[/tex]
[tex]P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{P(A)P(B)}{P(B)} = P(A)[/tex]

A bicycle company is designing women's bicycle frames The frames can accommodate any woman taller than 54.5 inches. Given that the heights of adult American women are normally distributed, with a mean of 65 inches and a standard deviation of 3.5 inches, what percentage of American women CANNOT use the bicycles designed by this company?
Using the normal distribution, it is found that 0.13% of American women CANNOT use the bicycles designed by this company.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 65, \sigma = 3.5[/tex]
The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the p-value of Z when X = 54.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{54.5 - 65}{3.5}[/tex]
Z = -3
Z = -3 has a p-value of 0.0013.
0.0013 = 0.13% of American women CANNOT use the bicycles designed by this company.
