The probability that both choose Black Panther as their favourite character is 189/3875.
How is the probability calculated?KHS students' list of their favourite Marvel comic character:
Spiderman - 45
Hulk - 30
Black panther - 28
Black widow - 17
Rocket raccoon - 5
Total = 125
The chances that two people can be drawn from a sample of 125 playing cards in 125\(C_{2}\) ways.
\(125C_{2}=\frac{125*124}{1*2} \\\\125C_{2}=\frac{15500}{2}\\\\125C_{2}= 7750\)
The event of choosing 2 Black Panthers from 28 can happen in 28 \(C_{2}\) ways.\(28C_{2}=\frac{28* 27}{1*2} \\\\28C_{2}=\frac{756}{2}\\\\28C_{2}= 378\)
The probability that both choose Black Panther as their favourite character is:\(P(BP) = \frac{28 C _{2}}{125C_{2}} \\\\P(BP) = \frac{378}{7750} \\\\P(BP) = \frac{189}{3875}\) or 0.04877
So, option c is correct.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. Probability informs us of the likelihood that an event will occur given enough trials.Probabilities can be expressed numerically by the number of desired outcomes, divided by the total number of outcomes, when dealing with experiments that are random and well-defined in a purely theoretical context (like flipping a coin).To learn more about probability, refer:

A health insurance company wants to know the proportion of admitted hospital patients who have a type 2 diabetes at orlando health hospitals. how large of a sample should be taken to estimate the proportion within 6% at 93% confidence?
To estimate the proportion of admitted hospital patients who have type 2 diabetes at Orlando Health Hospitals within a certain margin of error and confidence level,
we can use the following formula to determine the necessary sample size:
\(n = [(Z^2 * p * q) / E^2] / [1 + ((Z^2 * p * q) / E^2N)]\)
where:
n = sample size
Z = z-score for the desired confidence level (in this case, 1.81 for a 93% confidence level)
p = estimated proportion of patients with type 2 diabetes (unknown)
q = 1 - p
E = margin of error (0.06)
N = population size (unknown)
Since we do not know the estimated proportion of patients with type 2 diabetes or the population size,
we can assume a conservative estimate of p = q = 0.5, which maximizes the sample size required.
Plugging in the values, we get:
\(n = [(1.81^2 * 0.5 * 0.5) / 0.06^2] / [1 + ((1.81^2 * 0.5 * 0.5) / 0.06^2N)]\)
Simplifying, we get:
\(n = 1242.95 / [1 + (2.4 / N)]\)
To satisfy the requirements of the problem, we need to round up to the nearest whole number, so we need a sample size of at least 1243 patients.
Note that if we had a better estimate for p or N, we could use those values in the formula to get a more precise sample size.

Steven noticed that there were 72 lights on and 78 lights turned off. Enter the percent of the lights turned on.
The lights which were on was 48%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Given that there were 72 lights on, and 78 lights turned off.
We need to find the percent of the lights turned on.
So, percentage of something =
= number of thing / total number of the thing x 100%
Here, the number of thing = light on = 72
Total = 72 + 78 = 150
So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%
= 48%
Hence the lights which were on was 48%.

Which of the following is not an assumption for one-way analysis of variance?
The p populations of values of the response variable associated with the treatments have equal variances.
The samples of experimental units associated with the treatments are randomly selected.
The experimental units associated with the treatments are independent samples.
The number of sampled observations must be equal for all p treatments.
The distribution of the response variable is normal for all treatments.
The assumption that is not necessary for one-way analysis of variance (ANOVA) is:
"The distribution of the response variable is normal for all treatments."
In ANOVA, the primary assumption is that the populations of values of the response variable associated with the treatments have equal variances. This assumption is known as homogeneity of variances.
The other assumptions listed are indeed necessary for conducting a valid one-way ANOVA:
- The samples of experimental units associated with the treatments are randomly selected. Random sampling helps to ensure that the obtained samples are representative of the population.
- The experimental units associated with the treatments are independent samples. Independence is important to prevent any influence or bias between the treatments.
- The number of sampled observations must be equal for all p treatments. Equal sample sizes ensure fairness and balance in the analysis, allowing for valid comparisons between the treatment groups.
Therefore, the assumption that is not required for one-way ANOVA is that the distribution of the response variable is normal for all treatments. However, normality is often desired for accurate interpretation of the results and to ensure the validity of certain inferential procedures (e.g., confidence intervals, hypothesis tests) based on the ANOVA results.

The correct inequality to find the value of t is: 15 x 3t > 3000.
Let the number of days it takes for the number of people who have liked the video to reach more than 3,000 be t. According to the given statement, The number of people who like a particular video online triples every day after the day the video is posted.
If 15 people like the video on the day it is posted, then the total number of likes the next day is 3 x 15, i.e. 45 (3 times the number of people who like the video).
Therefore, the number of likes increases exponentially by a factor of 3 every day. So, we can write the number of likes in t days as 15 x 3t
To find t such that the number of people who have liked the video reaches more than 3,000, we can use the following inequality: 15 x 3t > 3000
We can simplify the above inequality as follows: 15 x 3t > 3000⇒ 3t > 200⇒ t > log3 200⇒ t > 5.7 (approx)
Therefore, it takes 6 days for the number of people who have liked the video to reach more than 3,000.

(5 pts) Consider the region R bounded by the graph of y=3−x², y=3x−1, and x=0. Find the volume of the solid obtained by rotating the region R about the y-axis.
The volume of the solid obtained by rotating the region R, bounded by the graphs of y = 3 - x², y = 3x - 1, and x = 0, about the y-axis is -28π cubic units.
The volume of the solid obtained by rotating the region R, bounded by the graphs of y = 3 - x², y = 3x - 1, and x = 0, about the y-axis can be found using the method of cylindrical shells.
To find the volume, we integrate the circumference of each shell multiplied by its height, summing up all the shells. The height of each shell is the difference between the y-values of the two curves at a given x-value, and the circumference is given by 2πx.
First, let's find the points where the two curves intersect. Setting the equations for y equal to each other, we have:
3 - x² = 3x - 1
Rearranging and simplifying:
x² + 3x - 4 = 0
Factoring the quadratic equation:
(x + 4)(x - 1) = 0
So, x = -4 and x = 1 are the x-coordinates of the intersection points.
Next, we integrate from x = -4 to x = 1. The volume of each shell is given by:
dV = 2πx(y₁ - y₂)dx
where y₁ is the upper curve (3 - x²) and y₂ is the lower curve (3x - 1).
Integrating the expression, we have:
V = ∫[from -4 to 1] 2πx((3 - x²) - (3x - 1))dx
Simplifying further:
V = 2π ∫[from -4 to 1] (4x - x³ - 2x + 1) dx
Integrating term by term:
V = 2π [(2x² - 0.25x⁴ - x² + x)] [from -4 to 1]
Evaluating the definite integral:
V = 2π [(2 - 0.25 - 1 + 1) - (32 - 4 - 16 + 4)]
V = 2π [2 - 16]
V = -28π cubic units
Therefore, the volume of the solid obtained by rotating the region R about the y-axis is -28π cubic units.

a rectangluar rug has a length that is 3 times its width. The perimieter is 56 feet. what are the dimensions?
Answer:
7 x 21
Step-by-step explanation:
We can say that the dimensions are a and b. Since this is a rectangle, we know that the perimeter will be 2a + 2b. So our first equation is:
2a + 2b = 56.
They also tell us that the length is 3 times its width. So we can say this:
a = 3b.
Now we can substitute, and we can do the full problem with the given info:
2a + 2b = 56
a = 3b
2a = 6b
6b + 2b = 56
8b = 56
b = 7
Now that we know b, we can multiply it by 3 to get a:
b = 7
a = 3b
a = 21.
So our answer is:
a = 21
b = 7
Answer:
Dimensions:
7 x 21
Answer:
Width=7
Length=21
Step-by-step explanation:
p=56 feet
L=3W
P=2L + 2W
56=2(3W)+2W
56=6W+2W
56=8W
W=56/8 = 7 ⇒ Width=7
L=3W
L=3*7
L=21 feet ( length=21 feet)

A. An item is regularly priced at $65. Bill bought it at a discount of 20% off the regular price. How much did Bill pay?
B. The wholesale price for a pillow is $4.50. A certain department store marks up the wholesale price by 40%. Find the price of the pillow in the department store.
Round your answer to the nearest cent, as necessary.
Answer:
A = $52.00B = $6.30Step-by-step explanation:
A. How much Bill paid AFTER the discount.Step 1: Convert the discounted percent to decimal
20% = 0.2
Step 2: Multiply the discount to the item regularly priced
0.2(65.00) = 13
So, Bill received a $13 discount, therefore, the amount he paid AFTER his discount is:
Step 3: Subtract the result (the discount Bill received) from the regular price
$65.00 - $13.00= $52.00
Therefore, Bill paid $52.00
B. The price of the pillow in the department store.Step 1: Multiply the wholesale price for a pillow by the marked-up the wholesale price
$4.50 × 40% = 1.8
Set up a fraction\(\frac{4.50}{x}=\frac{100\%}{40\%}\)
The reciprocal of both sides gives\(\frac{x}{4.50}=\frac{40}{100}\)
x = 1.8
Step 2: Add the result to the wholesale price for the pillow
4.50 + 1.8 = $6.3
Step 3: Round to the nearest cent
Add a zero behind the result = 6.30
Therefore, the price of the pillow in the department store is $6.30

================================================
Work Shown:
\(a \bowtie b = a + \sqrt{b+\sqrt{b+\sqrt{b+...}}}\\\\7 \bowtie g = 7 + \sqrt{g+\sqrt{g+\sqrt{g+...}}} = 9\\\\\sqrt{g+\sqrt{g+\sqrt{g+...}}} = 2\)
After subtracting 7 from both sides.
Note how because we have an infinite sequence of nested radicals, we can let \(x = \sqrt{g+\sqrt{g+...}}\) which means x is equal to 2 as well.
This lets us say
\(\sqrt{g+\sqrt{g+\sqrt{g+...}}} = \sqrt{g+x} = x\)
Solve the equation \(\sqrt{g+x}= x\) for x to get
\(\sqrt{g+x} = x\\\\g+x = x^2\\\\x^2-x-g = 0\\\\x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-1)\pm\sqrt{(-1)^2-4(1)(-g)}}{2(1)}\\\\x = \frac{1\pm\sqrt{1+4g}}{2}\\\\x = \frac{1+\sqrt{1+4g}}{2} \ \text{ or } \ x = \frac{1-\sqrt{1+4g}}{2}\)
Since x is positive, this means we only focus on the first equation in the last line above.
Earlier we let x be equal to the infinite nested radicals involving g, but x is also equal to 2. So plug in x = 2 and use that to find g.
\(x = \frac{1+\sqrt{1+4g}}{2}\\\\2 = \frac{1+\sqrt{1+4g}}{2}\\\\4 = 1+\sqrt{1+4g}\\\\3 = \sqrt{1+4g}\\\\9 = 1+4g\\\\1+4g = 9\\\\4g = 8\\\\g = 2\\\\\)
As a check, we can do the following
\(7 + \sqrt{2+\sqrt{2}} \approx 8.84775906502258\\\\7 + \sqrt{2+\sqrt{2+\sqrt{2}}} \approx 8.96157056080647\\\\7 + \sqrt{2+\sqrt{2+\sqrt{2+\sqrt{2}}}} \approx 8.9903694533444\\\\\)
we're slowly approaching 9
Answer: \(g = \boxed{2}\)
Step-by-step explanation:
\(\sqrt{g+\sqrt{g+\sqrt{g+...}}}=2\)

A model measured in feet (ft) is composed of two cones joined at their bases, as shown.
2 ft
4 ft
What is the exact surface area, in square feet, of the model?
4
1 ft
26 square feet is the exact surface area of the composed figure with two cones.
The composed figure has two cones.
The formula to find the surface area of cone is A=πr(r+√h²+r²))
Where r is radius and h is height of the cone.
Both the cones have radius of 1 ft and height of 2ft and 4 ft.
Area of cone 1=3.14×1(1+√4+1)
=3.14(1+√5)
=10.16 square fee
Area of cone 2=3.14×1(1+√16+1)
=3.14(1+√17)
=16.01square feet.
Total surface area = 10.16+16.01
=26.17 square feet.

Wildlife: Mallard Ducks and Canada Geese For mallard ducks and Canada geese, what percentage of nests are successful (at least one offspring survives)? Studies in Montana, Illinois, Wyoming, Utah, and California gave the following percentages of successful nests (Reference: The Wildlife Society Press, Washington, D.C.). x: Percentage success for mallard duck nests 56 85 52 13 39 y: Percentage success for Canada goose nests 24 53 60 69 18 (a) Use a calculator to verify that ??-245: ??2 = 14,755, 2y = 224; and (b) Use the results of part (a) to compute the sample mean, variance, and (c) Use the results of part (a) to compute the sample mean, variance, and ??? = 12,070. standard deviation for x, the percent of successful mallard nests. standard deviation for y, the percent of successful Canada goose nests.
(a) Using the given data, we can verify the calculations as follows: ∑x = 245, ∑x^2 = 14,755, ∑y = 224.
(b) To compute the sample mean, variance, and standard deviation for the percentage success of mallard duck nests (x), we use the formulas:
Sample Mean (x) = ∑x / n
Variance (s^2) = (∑x^2 - (n * x^2)) / (n - 1)
Standard Deviation (s) = √(s^2)
(c) Applying the formulas, we can compute the sample mean, variance, and standard deviation for x as follows:
Sample Mean (x) = 245 / 5 = 49
Variance (s^2) = (14,755 - (5 * 49^2)) / (5 - 1) = 4,285
Standard Deviation (s) = √(4,285) ≈ 65.5
Similarly, for the percentage success of Canada goose nests (y), the calculations can be done using the same formulas and the given values from part (a).

Step-by-step explanation:
Sadie uses 9.8 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
7.35 pints
Step-by-step explanation:
If we use 1/4 of the 9.8 pints for blue, then the remaining white paint takes up 3/4 of the 9.8 pints of paint. To find how many pints of paint is equal to 3/4 of it, you must multiply that fraction by the amount (9.8).
\(\frac{3}{4}\) * 9.8 (or 0.75 * 9.8) = 7.35
Therefore, 7.35 pints of the total paint used is white.
