Answer:
The best model is hypergeometric distribution.
Step-by-step explanation:
The probability would be best modeled with hypergeometric distribution.
Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.
The hypergeometric distribution differs from the binomial distribution in the lack of replacements.
Thus, the best model is hypergeometric distribution.

Find the LCD of the given rational equation
Answer:
[tex]=\frac{2x^3+x^2-11x+14}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}[/tex]
Step-by-step explanation:
Step 1: Factor [tex]x² + 2x - 8: (x - 2) (x + 4)[/tex]
[tex]=\frac{x}{x+4}+\frac{x-1}{x+2}+\frac{3}{\left(x-2\right)\left(x+4\right)}[/tex]
Step 2: Find the Least Common Multiplier of [tex]x + 4, x - 2, (x + 4), (x - 2)[/tex]
= [tex](x + 4) (x + 2) (x - 2)[/tex]
Step 3a: Conform the fractions based on the LCM (Least Common Multiplier)
= [tex]\frac{x\left(x+2\right)\left(x-2\right)}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}+\frac{\left(x-1\right)\left(x+4\right)\left(x-2\right)}{\left(x+2\right)\left(x+4\right)\left(x-2\right)}+\frac{3\left(x+2\right)}{\left(x-2\right)\left(x+4\right)\left(x+2\right)}[/tex]
Step 3b: The denominators are equal, so combine the fractions.
[tex]=\frac{x\left(x+2\right)\left(x-2\right)+\left(x-1\right)\left(x+4\right)\left(x-2\right)+3\left(x+2\right)}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}[/tex]
Step 4: Expand [tex]x(x + 2)(x - 2) +(x-1)(x+4)(x-2) + 3(x-2)[/tex]
[tex]=\frac{2x^3+x^2-11x+14}{\left(x+4\right)\left(x+2\right)\left(x-2\right)}[/tex]

5 - 2 (a + 3b) / 2 = ? / ?
Answer:
(5-2a+6b)/2
Step-by-step explanation:
According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2

How does saving money in an account with compound interest help protect you from inflation?
Answer:
Inflation is caused by the increase in prices of goods, and as prices of goods rise, the value of money itself would decrease. By saving money in a savings account with interest that might be equal or more than the level of inflation, your money would increase, which protects you from the devaluation of the savings you hold and the rising prices of goods.

Step-by-step explanation:
Step 1: Define Equation

Step 2: Solve for n
Divide 6 on both sides: 31 = 3n + 7Isolate n term: 24 = 3nIsolate n: 8 = nRewrite: n = 8Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: 186 = 6(3(8) + 7)Multiply: 186 = 6(24 + 7)Add: 186 = 6(31)Multiply: 186 = 186Here we see that 186 does indeed equal 186.

0 (0, -V5) and (0, V5)
Answer:
The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )
Step-by-step explanation:
Step(i):-
Given Ellipse 9 x² + 4 y² = 36
[tex]\frac{9x^{2} }{36} + \frac{4y^{2} }{36} =1[/tex]
⇒ [tex]\frac{x^{2} }{4} + \frac{y^{2} }{9} = 1[/tex]
Step(ii):-
The Major axis lies on y-axis
Foci of the Formula C² = a² -b² = 9-4 =5
C = √5
The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre
Given ellipse of the foci is lie on Y- axis
Final answer:-
The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )
12+(8divided by 2/3)- 2
Answer:

Step-by-step explanation:
12+(8/(2/3)-2
22
Answer:

There is a bag with 10 balls inside it. 2
are footballs, 3 are soccer balls, 1 is a
softball, 2 are baseballs, and 2 are
basketballs. If you were to reach in and
grab one ball, what is the probability
that it is a softball or not a basketball?
Enter your answer in simplest form.
P(softball or not a basketball)=
The probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.
What is probability?The likelihood or chance of an event occurring is measured by probability. Usually, it is stated as a number between 0 and 1, where 0 denotes an event's impossibility and 1 denotes its certainty.
According to question:There are 10 balls in total, and 2 of them are basketballs. So the number of balls that are not basketballs is 10 - 2 = 8.
Of these 8 balls, we know that 1 is a softball. So the number of balls that are either a softball or not a basketball is 1 + 8 = 9.
Therefore, the probability of grabbing a ball that is either a softball or not a basketball is:
P(softball or not a basketball) = 9/10
So the probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.

.The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel?
Answer:
1271.7in
Step-by-step explanation:
A complete rotation is = circumference of the wheel.
So calculate the circumference which is pi times diameter.
27 times pi (which is 3.14) = 84.78in one rotation
so if you make 15 rotations, you are multiplying it by 15
15 x 84.78 = 1271.7in

c. The distribution of all possible values that can be assumed by some statistic, computed from samples of the same size randomly drawn from the same population.
What is the statistical population?A population is the group of people from which a statistical sample is taken in statistics. Therefore, a population is any collection of people who have something in common. A statistically significant portion of a population, rather than the full population, may also be referred to as a sample.
When surveying a big number of people, it is just impracticable to examine everyone who fits the description you are looking at using a population parameter. It is often easier to study a smaller sample of participants, but by applying inferential statistics, it is possible to get a good approximation of the population parameter.
thus, statistical population is the distribution of all of the statistics calculated from all possible samples of the same size.
Therefore, The statistical population, which is calculated from samples of the same size randomly selected from the same population, is the distribution of all potential values that can be assumed by a statistic.

We have to find the equation of the line tangent to the function f(x) = 1 – x² at x = –3.
Determine the function's first derivative f(x), To get the slope at a given location, plug the specified point's x value into f'(x). To determine the tangent point's y coordinate, plug the value of x into f(x). The point-slope formula may be used to combine the slope from step 2 with the point from step 3 to produce the equation for the tangent line.
