The 32 ways to get a five-card combination containing two jacks and three aces.
(a) A full house consists of three of one kind and two of another kind. Therefore, there are 13 different choices for the rank of the triplet and 4 cards of the same rank. Once the triplet has been chosen, there are 12 choices for the rank of the pair and 4 cards of the same rank. Therefore, the number of ways to get a full house is as follows:$${13}{\times}{4}{\times}{12}{\times}{4}={7488}$$Therefore, there are 7488 ways to get a full house.(b) In this case, the two jacks and three aces must be chosen out of the 4 jacks and 4 aces in the deck. Therefore, the number of ways to get a five-card combination with two jacks and three aces is as follows:$$\frac{{4\choose2}{4\choose3}{44\choose0}}{5!}={32}$$Therefore, there are 32 ways to get a five-card combination containing two jacks and three aces.

i’m begging u guys please help
Answer:
y = 3
Step-by-step explanation:
All this question is asking is:
When x = 1, what does y equal?
To solve this problem, plug in 1 for x to get
\(y = \frac{1}{2} *6^1\)
Then, simplify!
Any number to the first power is the same number, so \(6^1 = 6\).
\(\frac{1}{2} * 6 = \frac{6}{2} = 3\)
y = 3.
Hope this helps!
Write an equation for the line in slope-intercept form.
Answer:
y=2x+2
Step-by-step explanation:
the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2
5. are there any conditions in which it would be acceptable to allow skewed variables into a research study? if so, describe these conditions.
Yes, there are conditions in which it can be acceptable to allow skewed variables into a research study. Skewed variables are variables that do not follow a symmetrical distribution and have a longer tail on one side.
In research, it is important to consider the appropriateness of including skewed variables based on the specific research question, study design, and analysis techniques. Here are a few conditions under which it might be acceptable:
1. Natural occurrence: If the variable being studied naturally exhibits a skewed distribution in the population, it may be necessary and acceptable to include it. For example, income data often exhibit right-skewness due to a few high-income outliers, but studying income inequality or socioeconomic disparities would require considering this variable.
2. Theoretical justification: If there is a strong theoretical rationale or prior research suggesting that the variable is expected to be skewed, it can be included in the study. This is particularly relevant when studying phenomena that inherently have asymmetric distributions, such as reaction times, human behavior, or certain psychological constructs.
3. Robust analysis techniques: If appropriate statistical techniques exist to handle skewed variables, it may be acceptable to include them. For instance, non-parametric tests or transformations (e.g., logarithmic or square root transformations) can be used to address skewness and still obtain meaningful results.
4. Subgroup analysis: If the skewness is driven by a particular subgroup within the data, researchers might consider conducting subgroup analysis or stratifying the data based on the skewed variable. This approach allows for exploring potential effects or relationships within specific subgroups while accounting for the skewness.
5. Sensitivity analysis: Researchers can also perform sensitivity analyses to assess the robustness of their findings to the inclusion or exclusion of skewed variables. This helps evaluate whether the results are sensitive to the specific distributional characteristics of the variable.
In summary, allowing skewed variables in a research study can be acceptable under certain conditions, such as when the variable naturally exhibits skewness, is theoretically justified, appropriate analysis techniques exist, or subgroup analysis is conducted. It is crucial to carefully consider the research question, study design, and analysis plan to ensure that the inclusion of skewed variables does not compromise the validity and interpretability of the findings.

I couldn’t fit it all on the screen but the question is “the graph below represents which system of inequalities?”
We are given a graph with lines representing inequalities. We are then asked to decipher which of the system of inequalities represents the graph.
In order to solve this question, it is easier to simply view them as normal lines with a general slope-intercept form of:
\(\begin{gathered} y=mx+c \\ \text{where,} \\ m=\text{slope} \\ c=y-\text{intercept (Where the graph cuts the y-axis)} \end{gathered}\)Whether or not the final expression for each line is meant to be a "greater than or equal to" or just simply "greater than" will be determined later on.
The Slope:
We need to calculate the slope (m) for both lines of the graph as this will move us 1 step closer to finding the equation of the line.
The formula for calculating the slope of a line is:
\(\begin{gathered} \text{Given two points,} \\ (x_1,y_1),(x_2,y_2) \\ \text{The slope of a line given these two points is:} \\ m=\frac{y_2-y_1}{x_2-x_1} \end{gathered}\)In order to find the slope of a line, we need to find two points on that line as we can infer from the formula above.
The points chosen for both lines is given below:
As we can see from above, line AB has two coordinates: A(0, 3) and B(-3, 0) while line AC has coordinates: A(0,3) and C(1.5, 0)
With these two points, we can now find the slope of both lines.
\(\begin{gathered} \text{ Line AB:} \\ \text{ Using A(0, 3), B(-3, 0), we have} \\ m=\frac{0-3}{-3-0}=-\frac{3}{-3} \\ m=1 \\ \\ \text{ LIne AC:} \\ \text{Using A(0, 3), C(1.5, 0), we have} \\ m=\frac{0-3}{1.5-0}=-\frac{3}{1.5} \\ m=-2 \end{gathered}\)Thus, the slope of line AB is 1 and the slope of line AC is -2.
Since we know that lines AB and AC cross the y-axis at point y = 3, it implies that the y-intercept (c) for both lines must be y = 3 as well.
Thus, we can write equation of both lines AB and AC as:
\(\begin{gathered} \text{ Using y = mx + c} \\ \text{ Line AB:} \\ y=x+3 \\ \text{while,} \\ \text{ LIne AC:} \\ y=-2x+3 \end{gathered}\)Now, that we know the equations, we just have to figure out whether they are greater than or equal to or otherwise.
The way we check is to set x and y to zero and see which inequality makes sense.
After performing this operation, we find that:
\(\begin{gathered} y\le-2x+3 \\ y\le x+3 \\ \text{put y = 0 , x = 0} \\ 0\le3\text{ (True)} \\ 0\le3\text{ (Also true} \end{gathered}\)Therefore, the final answer is:

If the firm's sales average $100,000 per month, how much money per year will go uncollected? A. $43,200. B. $72,000. C. $12,000. D. $51,600. E. $3,600 ...
The correct option is none of the given choices (E. $3,600). No money will go uncollected based on the provided information.
How much money is uncollected per year?To calculate the amount of money per year that will go uncollected, we need to determine the annual amount based on the monthly average sales.
Annual uncollected amount = Monthly average sales * 12 - Annual sales
Given that the firm's sales average $100,000 per month, the annual sales would be:
Annual sales = Monthly average sales * 12 = $100,000 * 12 = $1,200,000
Substituting this value into the equation:
Annual uncollected amount = $100,000 * 12 - $1,200,000 = $1,200,000 - $1,200,000 = $0
Therefore, the correct option is none of the given choices (E. $3,600). No money will go uncollected based on the provided information.

y=+- square root 7 over 3
y^2 + x^2 = 1 => x^2 = 1 - y^2 = 1 - 7/9 = 2/9 => x = +/- (√2) / 3
Answer: x = +/-(√2)/3
y=+- 3 over 3
x^2 = 1 - y^2 = 1 - 3/9 = 1 - 1/3 = 2/3 => x = +/-(√2/3)
Answer: x = +/-√(2/3)
y=+- 2 square root 2 over 2

Step-by-step explanation:
Number #1 = xNumber #2 = yx · y = 42x + y = 13 ⇒ y = 13 - xx · y = 42
x · (13 - x) = 42
13x - x² = 42
-x² + 13x - 42 = 0
(-1)(-x² + 13x - 42) = 0(-1)
x² - 13x + 42 = 0
