The experimental probability of flipping a head after five flips of a coin can be calculated by finding the ratio of the number of times a head appears to the total number of flips.
In this case, since there are two possible outcomes - a head or a tail - the total number of flips is five. Let's say, after five flips, a head appears three times. The experimental probability of flipping a head would be calculated as 3 (number of heads) divided by 5 (total number of flips), which equals 0.6.
Therefore, the experimental probability of flipping a head after five flips of the coin is [tex]0.6, or 60[/tex] %. It is important to note that the experimental probability may not accurately represent the theoretical probability, as it is based on a limited number of trials. The theoretical probability of flipping a head is 1/2, which is [tex]0.5 or 50[/tex]%.

Fill in the missing portions of the function to rewrite g(x) = 3a^2 − 42a + 135 to reveal the zeros of the function. What are the zeros of g(x)? (show your work!)
Enter your answers in the blanks:
g(x) = 3(_____)(_____)
Zeros: ______ and ______
Answer:
g(x) = 3(x-9)(x-5)
Zeros: x = 9 and x = 5.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
[tex]g(x) = 3x^{2} - 42a + 135[/tex]
So
[tex]a = 3, b = -42, c = 135[/tex]
[tex]\bigtriangleup = (-42)^{2} - 4*3*135 = 144[/tex]
[tex]x_{1} = \frac{-(-42) + \sqrt{144}}{2*3} = 9[/tex]
[tex]x_{2} = \frac{-(42) - \sqrt{144}}{2*3} = 5[/tex]
So
g(x) = 3(x-9)(x-5)
Zeros: x = 9 and x = 5.
In how many ways can a
recorder, facilitator, and
questioner be chosen in a club
containing 14 members?
Answer:
The answer is 364. There are 364 ways of choosing a recorder, a facilitator and a questioner froma club containing 14 members.
This is a Combination problem.
Combination is a branch of mathematics that deals with the problem relating to the number of iterations which allows one to select a sample of elements which we can term "r" from a collection or a group of distinct objects which we can name "n". The rules here are that replacements are not allowed and sample elements may be chosen in any order.
Step-by-step explanation:
Step I
The formula is given as
[tex]C (n,r) = \frac{n}{r} = \frac{n!}{(r!(n-r)!)}[/tex]
n (objects) = 14
r (sample) = 3
Step 2 - Insert Figures
C (14, 3) = [tex](\frac{14}{3})[/tex] = [tex]\frac{14!}{(3!(14-3)!)}[/tex]
= [tex]\frac{87178291200}{(6 X 39916800)}[/tex]
= [tex]\frac{87178291200}{239500800}[/tex]
= 364
Step 3
The total number of ways a recorder, a facilitator and a questioner can be chosen in a club containing 14 members therefore is 364.

A park ranger at a large national park wants to estimate the mean diameter of all the aspen trees in the park. The park ranger believes that due to environmental changes, the aspen trees are not growing as large as they were in 1975.
Answer:
(a) 0.15866
(b) Clustered, with two peaks
(c) Point estimate is 6.3 inches
Margin of error is 0.7 inches
(d) Yes
(e) Stratified sampling method
Step-by-step explanation:
(a) The given information are as follows
Mean diameter of Aspen trees, μ = 8 inches
Standard deviation, σ = 2.5 inches
[tex]z = \frac{x - \mu}{\sigma} = \frac{5.5 - 8 }{2.5} = -1[/tex]
Therefore;
p(x < 5.5) = p(z < -1)
From the z score table, we have p = 0.15866
Therefore, the probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = 0.15866
(b) The distribution of the Aspen trees can be described as clustered and having two peaks around 9.25 inches and 5.25 inches
(c) The point estimate is 5.6 + (7.0 - 5.6)/2 = 6.3
The margin of error = (7.0 - 5.6)/2 = 0.7 inches
(d) Yes, because the 8 inches is outside the range
(e) Stratified sampling method
Here, the Aspen trees are separated into the highland and lowland samples such that the measurement required will be representative of both highlands park and lowlands park.

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$ 7,299.92
Step-by-step explanation:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92

What is the answer to angle A? And do you mind to explain how
Answer:
45 degrees
Step-by-step explanation:
The sum of the angles of a triangle always adds up to 180.
10x + 8x + 5 + 85 = 180
Simplify by combining like terms.
18x + 90 = 180
Subtract 90 from both sides.
18x = 90
Divide both sides by 18.
x = 5 degrees
But the question didn't ask for x, it asked for angle A. So plug back in.
A = 8x + 5
A = 8(5) + 5
A = 40 + 5 = 45 degrees
Answer:
[tex]45 \: \: degrees[/tex]
Step-by-step explanation:
[tex]10x + 8x + 5 + 85 = 180 \\ 18x + 90 = 180 \\ 18x = 180 - 90 \\ 18x = 90 \\ \frac{18x}{18} = \frac{90}{18} \\ x = 5[/tex]
[tex]angle \: \: \: a = 8x + 5 \\ = 8 \times 5 + 5 \\ = 40 + 5 \\ = 45 \: \: degrees[/tex]

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
You have three card : 3, 4, 5 and 6.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/4
You then pick a second card without putting the first card back, the probability of picking a 3 is:
P = 1/3
=> The probability of picking a 3 and then picking a 3:
P = (1/4) x (1/3) = 1/12
