Answer:

53.33%

Step-by-step explanation:

There are a total of 4 + 3 + 8 = 15 coins in the jar. If we want to find the probability that the coin will not be a penny or a nickel, we need to find the number of coins that are not pennies or nickels, and divide that by the total number of coins in the jar.

The number of coins that are not pennies or nickels is 8 dimes. Therefore, the probability that the coin will not be a penny or a nickel is:

8 / 15

This simplifies to:

0.5333 or 53.33%

Therefore, the probability that the coin will NOT be a penny or a nickel is approximately 0.5333 or 53.33%.

It would take the girl's brother 44 minutes to deliver the newspapers by himself.

Let's assume that the girl's brother takes x minutes to deliver the newspapers by himself.

If the girl takes 44 minutes to deliver the newspapers alone, and when her brother helps, they finish in 22 minutes, we can set up the following equation based on the work rates:

1/44 + 1/x = 1/22

This equation represents the combined work rate of the girl and her brother when they work together. The left side of the equation represents the rate at which they can complete the task together, and the right side represents the reciprocal of the time it takes them (in minutes) to finish the task.

To solve for x, we can simplify the equation:

1/x = 1/22 - 1/44

Taking the least common denominator, we get:

1/x = (2 - 1) / 44

1/x = 1/44

Cross-multiplying, we have:

x = 44

Therefore, it would take the girl's brother 44 minutes to deliver the newspapers by himself.

Solution:

As, two set of data are each symmetrical and do not contain outliers.

To find the center , the best way is to find Median of data set.Median of Data set is the mid value of Data that is center of Data.

As, you have to find variability , mean can't measure variability. Mean deviation would have been better option.

So, MAD=Median absolute Deviation , would be better tool to measure variability. Because it is Absolute difference between median and Each value of data set.

So, Option (C) median and MAD, would be best way to compare the two given data set.

The best choice for a deep spot to take a swim is to go to a place in the river where the cross-sectional area is larger, and the water flows slower.

If you are looking for a deep spot to take a swim in a local river, the best choice is to go where the water flows slowly. The speed of the water is determined by the formula:

v=Q/A,

where v is the speed of the water, Q is the discharge rate, and A is the cross-sectional area of the river. As Q is constant for the same river, a slower water flow can be achieved by increasing A, which is the cross-sectional area of the river. Therefore, the best choice for a deep spot to take a swim is to go to a place in the river where the cross-sectional area is larger, and the water flows slower.

The boxplot which is reasonable to the summary of the data used to create the histogram is equals to boxplot A. So, correct answer is option (c).

Histogram is a graph which discribes the distribution of data by using of bars of different heights and same width. In this problem, we'll have a histogram and 3 box plots as box plot A, box plot B and box plot C, and we have to choose here which of these 3 box spots is a reasonable summary of the data. We can see that the histogram in above figure is skewed to left because it's maximum data present on the right end. The box plot C, is representing a normally distributed data, but are data is right side distributed so, it is wrong. Similarly, as we see box plot B shows distribution of data in left end, which is also not right choice. So, boxplot A is correct because it's showing the maximum data and the median where we have. We can see the median line over her median on the right hand. Thus, data is very highly negatively skewed hence boxplot A is appropriate.

The probability that exactly 5 out of 6 randomly selected Americans donated money to a charitable cause in 2021 is approximately 0.3931, or 39.31%.

The probability of a single American donating money to a charitable organization in 2021 is given as 81%. Therefore, the probability of an individual not donating is 1 - 0.81 = 0.19.

To calculate the probability of exactly 5 out of 6 Americans donating, we can use the binomial probability formula:

P(X = k) = (n C k) * p^k * (1 - p)^(n - k)

Where:

P(X = k) represents the probability of exactly k successes (donations).

(n C k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.

p is the probability of success (donation) in a single trial.

(1 - p) represents the probability of failure (not donating) in a single trial.

n is the total number of trials (sample size).

In this case, n = 6, k = 5, p = 0.81, and (1 - p) = 0.19.

Plugging in these values, we can calculate the probability:

P(X = 5) = (6 C 5) * (0.81)^5 * (0.19)^(6 - 5)

P(X = 5) = 6 * (0.81)^5 * (0.19)^1

P(X = 5) = 0.3931

Therefore, the probability that exactly 5 out of 6 randomly selected Americans donated money to a charitable cause in 2021 is approximately 0.3931, or 39.31%.

Answer:

Step-by-step explanation:

The substitution v = y^1-n transforms the Bernoulli equation dy/dx + P(x)y = Q(x)y^n into the linear equation dv/dx+(1-n)P(x)v(x) = (1 - n)Q(x) is shown below.

An equation is in the form  

dy/dx +P(x)y=Q(x)yⁿ,  where P and Q are functions of x alone or constants, is called Bernoulli's equation.

The substitution using \(v = y^{1-n}\)

Differentiate both side with respect to 'x'

\(v^{'} = (1-n)y^{-n}y^{'}\)

\(\frac{dy}{dx} = \frac{1}{1-n} y^{n}v^{'}\)

we get, \(\frac{1}{1-n} y^{n}v^{'}\) + P(x)y = Q(x)yⁿ

= \(v^{'} + (1-n)P(x)y^{1-n} = (1-n)Q(x)\)

using \(v = y^{1-n}\)

The given equation is well expressed as:

\(v^{'} + (1-n)P(x)v = (1-n)Q(x)\)

or dv/dx + (1-n)P(x)v(x) = (1 - n)Q(x)

The solution to the differential equation y(t) = Ce^(-2t) + 15 that satisfies the initial condition y(0) = 9 is: y(t) = -6e^(-2t) + 15.

To find the solution that satisfies the initial condition y(0) = 9, we substitute t = 0 into the general solution of the differential equation y(t) = Ce^(-2t) + 15:

y(0) = Ce^(-2(0)) + 15

9 = Ce^0 + 15

9 = C + 15

Now, we can solve this equation for C:

C = 9 - 15

C = -6

Therefore, the value of the constant C is -6.

Now that we have determined the value of C, we can substitute it back into the general solution to obtain the particular solution that satisfies the initial condition:

y(t) = Ce^(-2t) + 15

y(t) = -6e^(-2t) + 15

This equation represents the unique solution to the differential equation that meets the given initial condition. The term -6e^(-2t) represents the complementary solution, which accounts for the general behavior of the differential equation, while the constant term 15 represents the particular solution that satisfies the initial condition.

It's important to note that the exponential term e^(-2t) decays as t increases, so the value of y(t) approaches the constant term 15 as time goes to infinity. The negative coefficient -6 reflects the decreasing nature of the exponential term, causing y(t) to approach the steady-state value of 15 from above.

The measure for the angle m∠D of the quadrilateral CDEF is equal to 90°

For any quadrilateral, the sum of its four interior angles is equal to 360°, hence we shall calculate for the angle m∠D by first finding the value of x as follows:

17x + 5 + 13x + 7 + 118° + 80° = 360°

30x + 210° = 360°

30x = 360° - 210° {subtract 210° from both sides}

30x = 150°

x = 150°/30

x = 5

Explanation:

that's because Cosine is adjacent to the angle (the angle being 30 degrees and the side next to it is 43mm) divided by the hypotenuse (longest side of a right triangle. The 50 mm). A way you can remember the sin, cosine and tangent is SOH CAH TOA. Sine=opposite over hypotenuse, Cosine = adjacent over hypotenuse, Tangent = opposite over adjacent. For the next one, it is the same principal. X is adjacent to 22 degrees and the other number is the hypotenuse so it has to be Cosine.

To test the hypothesis that the mean weight of two sheets is equal (μ1 - μ2) against the alternative that it is not, and assuming equal variances, we can use a two-sample t-test. The t-statistic can be calculated using the following formula:

where:

x1 and x2 are the sample means of the two sheets,

s_p is the pooled standard deviation,

n1 and n2 are the sample sizes.

The pooled standard deviation (s_p) can be calculated using the following formula:

s_p = sqrt(((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2))

The total score is given as 15 points. So we can write the equation:

2t + 3 = 15

The triangle inequality is proved. It states that the absolute value of the sum of two real numbers is always greater than or equal to the sum of their absolute values. This inequality is important because it helps us to understand the relationship between the lengths of the sides of a triangle and the length of its hypotenuse.

The triangle inequality is a fundamental concept in mathematics, and it is used to prove many other theorems and inequalities. It states that if x and y are real numbers, then |x| + |y| ≥ |x + y| (where |x| represents the absolute value of x, which equals x if x ≥ 0 and equals −x if x < 0).

To prove the triangle inequality, we can use the following steps:

1. Start with the definition of absolute value: |x| = x if x ≥ 0 and |x| = −x if x < 0.

2. Use this definition to write |x + y| in terms of |x| and |y|: |x + y| = |x| + |y| if x + y ≥ 0 and |x + y| = −(x + y) if x + y < 0.

3. Use the fact that |x| ≥ 0 and |y| ≥ 0 to write |x + y| in terms of |x| and |y|: |x + y| = |x| + |y| if x + y ≥ 0 and |x + y| = |x| + |y| if x + y < 0.

4. Combine the two cases to get the triangle inequality: |x + y| = |x| + |y| if x + y ≥ 0 and |x + y| = |x| + |y| if x + y < 0, so |x + y| ≥ |x| + |y| in all cases.

Therefore, the triangle inequality is proved. It states that the absolute value of the sum of two real numbers is always greater than or equal to the sum of their absolute values. This inequality is important because it helps us to understand the relationship between the lengths of the sides of a triangle and the length of its hypotenuse.
