A 5-card poker hand is said to be a full house if it consists of 3 cards of the same denomination and 2 other cards of the same denomination (dierent from the rst denomination). Thus, one kind of full house is three of a kind plus a pair. What is the probability that one is dealt a full house
To calculate the probability of being dealt a full house in a 5-card poker hand, we need to determine the number of favorable outcomes (full house hands) and the total number of possible outcomes (all possible 5-card hands).
A full house consists of 3 cards of the same denomination (three of a kind) and 2 cards of another denomination (a pair). There are 13 denominations in a standard deck of cards (Ace, 2, 3, ..., 10, Jack, Queen, King), and for each denomination, there are 4 cards (one in each suit).
To calculate the number of full house hands, we can consider choosing the denomination for the three of a kind (13 choices) and then choosing the denomination for the pair (12 choices since it must be different from the first denomination).
For the three chosen denominations, we choose 3 suits for the three of a kind (4 choices each) and 2 suits for the pair (4 choices each).
The total number of possible 5-card hands is calculated using the combination formula: C(52, 5) = 2,598,960.
Therefore, the probability of being dealt a full house is:
P(full house) = (13 * 12 * C(4, 3) * C(4, 2)) / C(52, 5)
Calculating this expression gives the probability of being dealt a full house in a 5-card poker hand.

Let it be:
• x: The larger number.
,• y: The smaller number.
Then, we can write the following system of equations:
\(\begin{cases}x+y=2\Rightarrow\text{ Equation 1} \\ 3x+2y=20\Rightarrow\text{ Equation 2}\end{cases}\)To solve the system of equations, we can use the elimination method.
Step 1: Multiply by -3 the Equation 1.
\(\begin{gathered} -3(x+y)=2\cdot-3 \\ \text{ Apply the distributive property on the left side} \\ -3\cdot x-3\cdot y=-6 \\ -3x-3y=-6 \end{gathered}\)Step 2: We add both equations.
\(\begin{gathered} -3x-3y=-6 \\ 3x+2y=20\text{ +} \\ --------- \\ 0x-y=14 \\ -y=14 \end{gathered}\)Step 3: We solve the resultant equation.
\(\begin{gathered} \text{ Multiply by -1 from both sides} \\ -1\cdot-y=-1\cdot14 \\ y=-14 \end{gathered}\)Step 4: We replace the value of y in any of the initial equations. For example, in Equation 1. Then, we solve for x.
\(\begin{gathered} x+y=2 \\ x-14=2 \\ \text{ Add 14 from both equations.} \\ x-14+14=2+14 \\ x=16 \end{gathered}\)Therefore, the larger number is 16, and the smaller number is -14.
Explain the difference between a matched-subjects design and a repeated-measures design. In a repeated-measures design, subjects are used in treatment conditions. In a design, each subject in one sample in the other sample with respect to .
The main difference between a matched-subjects design and a repeated-measures design lies in how the subjects are used and the nature of the comparisons being made.
In a matched-subjects design, subjects are carefully paired or matched based on specific characteristics that are relevant to the study. These characteristics could be demographic variables, pre-existing conditions, or any other relevant factors. The idea behind matching is to create pairs of subjects that are similar or comparable on these characteristics, so that any differences observed between them can be attributed to the independent variable being studied. Each member of the pair is then assigned to different treatment conditions. The comparisons in a matched-subjects design are typically made within pairs, focusing on the differences between the two members of each pair.
On the other hand, in a repeated-measures design, the same subjects are used in multiple treatment conditions. Each subject is exposed to all treatment conditions or levels of the independent variable. This allows for a direct comparison of the same subject's responses or performance across different conditions. By using the same subjects, individual differences and variability between subjects are minimized, and any differences observed can be attributed to the effects of the independent variable. The comparisons in a repeated-measures design are typically made within subjects, focusing on the differences in their responses across the different conditions.

27
The mean of the distribution of sample means would be 27 hours, which is the same as the average life of the candles.
This is because the sample means would be expected to be centered around the population mean.
The standard deviation of the distribution of sample means (also known as the standard error of the mean) can be calculated using the formula:
standard deviation of sample means = standard deviation of population / square root of sample size
In this case, the standard deviation of sample means would be:
6 / square root of 4 = 3

2) You wish to accumulate $50,000 in an ordinary annuity which pays 12% interest compounded quarterly. You wish to make periodic payments at the end of each quarter for 8 years. The formula for an ordinary annuity is S=R[{1+in--] A) What is the value for I that you will use ? B) What is the value for n that you will use ? C) What is the value of the periodic payment R?
The value for I is 0.03, the value for n is 32, and the value of the periodic payment R is approximately $1,503.50
To solve this problem, let's break it down into the following components:
A) The value for I:
The interest rate per period (I) needs to be adjusted to match the compounding frequency. Since the interest is compounded quarterly, we need to divide the annual interest rate by the number of compounding periods per year.
I = Annual interest rate / Compounding periods per year
I = 12% / 4
I = 0.12 / 4
I = 0.03
B) The value for n:
The number of periods (n) is determined by the number of years multiplied by the number of compounding periods per year.
n = Number of years x Compounding periods per year
n = 8 years x 4
n = 32
C) The value of the periodic payment R:
We can use the formula for the future value of an ordinary annuity to find the periodic payment R:
S = R * [(1 + I)^n - 1] / I
50,000 = R * [(1 + 0.03)^32 - 1] / 0.03
50,000 = R * (1.03^32 - 1) / 0.03
50,000 = R * (1.999 - 1) / 0.03
50,000 = R * 0.999 / 0.03
R = 50,000 * 0.03 / 0.999
R = 1,503.50
Therefore, the value for I is 0.03, the value for n is 32, and the value of the periodic payment R is approximately $1,503.50.

They are having trouble deciding who will do what task, so they came up with a method based on probability. Letitia grabs some spoons and puts the is a bag. Some have purple handles and others have green handles. Scott has to pick two of the spoons. If their handles are the same, Scott will wash. If they are different colors, he will dry. It turns out there are two purple spoons and three green ones. What is the probability of Scott washing the dishes?
Answer:
The probability that Scott will wash is 2.5
Step-by-step explanation:
Given
Let the events be: P = Purple and G = Green
\(P = 2\)
\(G = 3\)
Required
The probability of Scott washing the dishes
If Scott washes the dishes, then it means he picks two spoons of the same color handle.
So, we have to calculate the probability of picking the same handle. i.e.
\(P(Same) = P(G_1\ and\ G_2) + P(P_1\ and\ P_2)\)
This gives:
\(P(G_1\ and\ G_2) = P(G_1) * P(G_2)\)
\(P(G_1\ and\ G_2) = \frac{n(G)}{Total} * \frac{n(G)-1}{Total - 1}\)
\(P(G_1\ and\ G_2) = \frac{3}{5} * \frac{3-1}{5- 1}\)
\(P(G_1\ and\ G_2) = \frac{3}{5} * \frac{2}{4}\)
\(P(G_1\ and\ G_2) = \frac{3}{10}\)
\(P(P_1\ and\ P_2) = P(P_1) * P(P_2)\)
\(P(P_1\ and\ P_2) = \frac{n(P)}{Total} * \frac{n(P)-1}{Total - 1}\)
\(P(P_1\ and\ P_2) = \frac{2}{5} * \frac{2-1}{5- 1}\)
\(P(P_1\ and\ P_2) = \frac{2}{5} * \frac{1}{4}\)
\(P(P_1\ and\ P_2) = \frac{1}{10}\)
Note that: 1 is subtracted because it is a probability without replacement
So, we have:
\(P(Same) = P(G_1\ and\ G_2) + P(P_1\ and\ P_2)\)
\(P(Same) = \frac{3}{10} + \frac{1}{10}\)
\(P(Same) = \frac{3+1}{10}\)
\(P(Same) = \frac{4}{10}\)
\(P(Same) = \frac{2}{5}\)
Which is the equation of the line through the point (−3, 8) that is perpendicular to the line y=14x+12?
Answer:
y = -1/14x + 109/14
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 14x + 12. Its slope is 14. A line perpendicular to this one will have a slope of -1/14.
Plug this value (-1/14) into your standard point-slope equation of y = mx + b.
y = -1/14x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-3, 8). Plug in the x and y values into the x and y of the standard equation.
8 = -1/14(-3) + b
To find b, multiply the slope and the input of x (-3)
8 = 3/14 + b
Now, subtract 3/14 from both sides to isolate b.
8 - 3/14 = b
112/14 - 3/14 = b
109/14 = b
Plug this into your standard equation.
y = -1/14x + 109/14
This equation is parallel/perpendicular to your given equation (y = 14x + 12) and contains point (-3, 8)

What is a congruent shape?
Congruent refers to things that are exactly the same size and shape. Even if we flip, turn, or rotate the forms, the shape and size should remain the same.
Congruent refers to something that is "absolutely equal" in terms of size and shape. The shapes hold true regardless of how we rotate, flip, or turn them.
Shapes that are identical to one another are said to be congruent. Both the matching sides and the corresponding angles match. We must examine all of the shapes' angles and sides in order to accomplish this. Two shapes that are similar to one another can be stacked perfectly.
