a bin of 10 light bulbs contains 4 that are defective, if 3 bulbs are chosen with replacement from the bin, what is the chane that exactly 2 fo bulbs in the sample are defective

The formula for the volume (V) of a cylinder is given by:

V = πr^2h

where r is the radius of the cylinder and h is its height.

We are given the diameter of the cylinder as 28 meters, so the radius (r) is half of that, or 14 meters.

Using the given height of 7 and one half meters, we can now calculate the volume of the cylinder as follows:

V = πr^2h = (22/7) * (14)^2 * (7.5) = 4,620 cubic meters (rounded to the nearest whole number)

Therefore, the approximate volume of the cylinder is 4,620 cubic meters.

The weight of the plane if it is carrying gallons of fuel is 2336 pounds, under the condition of when carrying 10 gallons, and 45 gallons he airplane weighs 2056  and 2252 pounds.
We can utilize the two given points to create two linear equations

y = mx + b
2056 = 10m + b
2252 = 45m + b

We can find m and b by subtracting the first equation from the second equation:

(45m + b) - (10m + b) = 2252 - 2056
35m = 196
m = 5.6

For finding b by substituting m into one of the original equations:

2056 = 10(5.6) + b
b = 2000

The equation is

y = 5.6x + 2000

To evaluate  how much the airplane weighs when carrying 60 gallons of fuel,  now lets substitute x into the equation

y = 5.6(60) + 2000
y = 336 + 2000
y = 2336

Approximately 39% of coin tosses resulted in tails

Probability is the likelihood or possibility of an event. For example, the probability of tossing a coin  is ½ because there is 1 way to get heads and the total number of possible outcomes is 2 (heads or tails).

Since the coin landed  heads 31 times in 51 tosses, it must be 51 - 31 = 20 times.

We can use the following formula to figure out the percentage of conversions that result in leads.

percentage of tails = (number of tails / total number of spins) x 100

Let's paste the values ​​we have:

percentage of heads = (20/51) x 100

percentage of heads = 0.39215686274 x 100

percentage of tails = 39.215686274

The equation in the interval [0, 2π) 3csc^2x=4 are: x = π/3 and x = 2π/3.

We can start solving the equation by isolating the csc^2(x) term, using the fact that csc^2(x) = 1/sin^2(x):

3csc^2(x) = 4

csc^2(x) = 4/3

1/sin^2(x) = 4/3

sin^2(x) = 3/4

Taking the square root of both sides, we get:

sin(x) = ±√(3/4) = ±(√3)/2

Since we are looking for solutions in the interval [0, 2π), we need to determine the angles in this interval whose sine is equal to ±(√3)/2. These angles are π/3 and 2π/3, since sin(π/3) = √3/2 and sin(2π/3) = √3/2.

In the given range, the smallest multiple of 14 is 98, and the largest multiple of 14 is 770. ((770-98)/14) + 1 = 49 multiples of 14.

(b) y = 4x:

Substituting the x-values from the set P into the equation, we get:

Let's the weight of Case C = "x" grams.

From the information:

Case A = 12 times heavier than Case B,

Therefore, the weight of Case B = 1/12 of Case A's weight:

Weight of Case B = (1/12) * Weight of Case A

Case B = 16 times heavier than Case C,

so, weight of Case C = 1/16 of Case B's weight:

Weight of Case C = (1/16) * Weight of Case B

The weight of Case A = 8,640g,

Let's substitute the value into the equations to find the weight of Case C:

Weight of Case B = (1/12) * 8,640 = 720g

Weight of Case C = (1/16) * 720 = 45g

Thus, the weight of Case C is 45 grams.

The length and width of the square picture frame are both approximately 7.08 inches. The dimensions of the picture that would fit inside the frame are approximately 6.5 inches.

In a square, the diagonal is a line segment that connects opposite corners of the square. Since a square has four congruent sides, we can use the Pythagorean theorem to find the length of the diagonal "d" in terms of the length "s" of the sides. The formula used is given by

=> d² = s² + s²

Here we have

The diagonal of the frame is 10 inches

Let's assume that the length and width of the square picture frame are both "x" inches.

Then, using the Pythagorean theorem, we can express the length of the diagonal (d) of the square picture frame in terms of "x":

=> d² = x² + x²  

Simplifying this equation, we get:

=> d² = 2x²

We know that the length of the diagonal is 10 inches, so we can write:

=> 100 = 2x²

Solving for "x", we get:

=> x² = 50

=> x = 5√2

=> x = 7.071 inches

Therefore,

The length and width of the square picture frame are both approximately 7.08 inches.

To find the dimensions of the picture that would fit inside the frame, we can simply subtract a margin of, say, 0.5 inches from each dimension to allow for the picture to fit comfortably within the frame.

So, the dimensions of the picture that would fit inside the frame are approximately 6.5 inches by 6.5 inches.

Therefore,

The length and width of the square picture frame are both approximately 7.08 inches. The dimensions of the picture that would fit inside the frame are approximately 6.5 inches.

Step-by-step explanation:

The median should be used to determine which location typically has the cooler temperature, with Beach Town being the location with higher temperatures due to its skewed data.

The measure of center that should be used to determine which location typically has the cooler temperature is the Median, because Beach Town is skewed.

The median is a measure of center that represents the middle value of a data set when it is arranged in ascending or descending order. When comparing the two histograms, Sunny Town's data is symmetric, meaning that it has roughly equal frequencies on both sides of the center. In this case, the median could be a good representation of the typical temperature in Sunny Town.

However, Beach Town's data is skewed, meaning that it is not symmetrical and has a longer tail on one side of the center. This indicates that there are more occurrences of higher temperatures in Beach Town compared to Sunny Town. In skewed data, the mean can be affected by extreme values, making it less reliable as a measure of center. The median, on the other hand, is less influenced by extreme values and can give a better indication of the typical temperature in Beach Town.

Therefore, the median should be used to determine which location typically has the cooler temperature, with Beach Town being the location with higher temperatures due to its skewed data.

The null hypothesis H0: μ ≤ 30 mean raw score for the school's applicants is less than or equal to 30 and the alternative hypothesis Ha: μ > 30

We can utilize a one-tailed t-test since we don't know the population standard deviation and our sample size is less than 30. The test statistic is evaluated

t = (x' - μ) / (s / √n)

here
x'= sample mean = 31,
μ = hypothesized population mean = 30,
s =  standard deviation = 2.5,
n = sample size = 50.

t = (31 - 30) / (2.5 / √50)

Applying  t-distribution table with degrees of freedom (df) = n - 1 = 49 and a significance level of α = 0.01, we find that the critical value is
