A bag contains 15 marbles. The probability of randomly selecting a green marble is One-third. The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is StartFraction 1 over 15 EndFraction. What is the probability of randomly selecting a red marble? StartFraction 1 over 45 EndFraction StartFraction 1 over 5 EndFraction StartFraction 4 over 15 EndFraction Two-fifths.
The probability of randomly selecting a red marble will be P=1/45
What is probability?
The probability is defined as the chances of happening of any event it is defined as the ratio of required outcomes to the total number.
Now here is the question, it is given that
Total marbles in the bag = 15
probability of randomly selecting a green marble = [tex]\dfrac{1}{3}[/tex]
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is [tex]\dfrac{1}{15}[/tex]
So, the probability of randomly selecting a red marble will be the product of the two probabilities.
[tex]P= \dfrac{1}{3} \times \dfrac{1}{15}[/tex]
[tex]P=\dfrac{1}{45}[/tex]
Thus the probability of randomly selecting a red marble will be
[tex]P= \dfrac{1}{45}[/tex]

Answer:
f^-1 = 3(x + 1)
Step-by-step explanation:
f(x) = (3 - x)/x
y = (3 - x)/x
x = (3 - y)/y
xy = 3 - y
xy + y = 3
y(x + 1) = 3
y = 3/(x + 1)

It is known that the point P(-9,18) belongs to the graph of the function y=k/x. Find k.
Answer:
[tex]k = (-162)[/tex].
Step-by-step explanation:
A point of the form [tex](x_{0},\, y_{0})[/tex] belongs to the graph of this function, [tex]y = k / x[/tex], if and only if the equation of this function holds after substituting in [tex]x = x_{0}[/tex] and [tex]y = y_{0}[/tex].
The question states that the point [tex](-9,\, 18)[/tex] belongs to the graph of this function. Thus, the equation of this function, [tex]y = k / x[/tex], should hold after substituting in [tex]x = (-9)[/tex] and [tex]y = 18[/tex]:
[tex]y = k / x[/tex].
[tex]18 = k / (-9)[/tex].
Solve this equation for the constant [tex]k[/tex]:
[tex]\begin{aligned}k &= 18 \times (-9) \\ &= (-162)\end{aligned}[/tex].
Thus, [tex]k = (-162)[/tex].
If there are 1,400 costumers in a given week, how many would you expect to prefer chocolate strawberry or vert berry mix?
Answer:
770 customers
Step-by-step explanation:
Oooh I love these types of questions!
First we should add all of the numbers to find the total number of people so we can set up a proportion later.
70+36+46+40+8=200
Now that we've found the total, we need to find chocolate strawberry and vert berry, because the wording "or" would mean either. If the wording said "and" we would not have enough information to solve that.
Chocolate Strawberry is 70, and Very Berry is 40. Add that to get 110.
Now we have our needed numbers to make a proportion! This is because for each 200 people, we know that they'd want 110 Chocolate Strawberry or Very Berry.
So we would need to make a proportion for 1400.
110/200=x/1400
Cross multiply (or do that trick where you divide 1400 by 200 and then multiply 110 by that number, but cross-multiplying is a good habit)
110(1400)=200x
Simplify
154000=200x
Isolate the variable
154000=200x
/200 /200
770=x
And that would be your answer! If I made any errors, please tell me!

Your car gets 25 mi/gal around town and 30 mi/gal on the highway.
a. If 50% of the miles you drive are on the highway and 50% are around town, what
is your overall average miles per gallon?
b. If 60% of the miles you drive are on the highway and 40% are around town, what
is your overall average miles per gallon?
need work shown if possible im really confused
Answer:
Ok so what it is asking on part A is if your driving 50% on the highway which is 30 miles a gallon and 50% on around the town which is 25 miles a gallon then how many miles a gallon are you getting and the answer for that you need to first find what kind of problem it is and in this case you are working with percents so what you first want to do is multiply 50% to both 30 and 25 which will be 15 and 12.5 then add those together to get you answer now do the same for part B but instead of 50% it will be 60% and 40%.

Say you've got a credit score of 750, and you miss one credit card payment will
this impact your credit score MORE or LESS than if your original score was 650?
Why do you think this is the case?
The higher the score, the greater the decrease will be, since the greater the value of the decreased percentage will be greater too.
PercentagesGiven that you've got a credit score of 750, and you miss one credit card payment, to determine if this will impact your credit score MORE or LESS than if your original score was 650, the following calculation must be performed:
Suppose that a non-payment reduces the value of the score by 5%.100 - 5 = 95750 x 0.95 = 712.5 (-37.5)650 x 0.95 = 617.5 (-32.5)Thus, as can be seen, the higher the score, the greater the decrease will be, since the greater the value of the decreased percentage will be.

A biologist hopes to estimate the proportion of alligators in Florida that are adult. When sampling alligators, the biologist computes the one-proportion Z-interval going from 0.67 to 0.74 at 99% confidence. The margin of error for a 95% confidence interval would be:_____.
Using the z-distribution, as we are working with a proportion, it is found that the margin of error for a 95% confidence interval would be of 0.0008.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
Considering the 99% confidence interval, which has z = 2.575, the estimate and the sample size are given by:
[tex]\pi = \frac{0.67 + 0.74}{2} = 0.705[/tex]
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.74 - 0.705 = 2.575\sqrt{\frac{0.705(0.295)}{n}}[/tex]
[tex]0.035 = 2.575\sqrt{\frac{0.705(0.295)}{n}}[/tex]
[tex]0.035\sqrt{n} = 2.575\sqrt{0.705(0.295)}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.705(0.295)}}{0.035}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.705(0.295)}}{0.035}\right)^2[/tex]
[tex]n = 1126[/tex]
Hence, the margin of error is given by:
[tex]M = 1.96\sqrt{\frac{0.705(0.295)}{1126}} = 0.0008[/tex]
