Step-by-step explanation:

46.53 is the Trimmed mean after removing, 20% of the trimmed mean from all the given lengths of 3-Point Kick for NCAA Division 1-A Football.

The given data is:

Lengths of 3-point kicks = 30 32 34 40 41 43 43 44 45 45 46 47 52 51 53 56 56 57 60.

Trimmed mean = 20%

The trimmed mean is defined as the statistical measure of central tendency. That means calculating the mean value of the given tendency of observations.

Trimmed observations = 20 x (20/100) = 4

These, trimmed observations denote that 2 observations must be trimmed from both sides when they are arranged in ascending order.

Ascending order of lengths =  30 32 34 40 41 43 43 44 45 45 46 47 51 52 53 56 56 57 60.

The trimmed Mean =  (34 40 41 43 43 44 45 45 46 47 51 52 53 56 56)/ 15

Trimmed mean = 698/15 = 46.53

Therefore, we can conclude that 46.53 is the Trimmed Mean after removing, 20% of the trimmed mean.

The area of a square with side length 2 inches greater than the area of a circle with radius 1.2 inches.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Given:

Area of Square = side x side

we have side = 2 inches

So, Area of Square = side x side

                                = 2 x 2

                                = 4 inch²

and, Area of Circle = πr²

We have radius = 1.2 inch

So, Area of Circle = 3.14 x (1.2)²

                              = 4.5216 inch²

So, Area of Square is greater than Area of Circle.

Answer:

Souta made his first error in Step 3, where he found the differences between each score and the mean. He did not find the absolute values of these differences, which means he did not calculate the mean absolute deviation correctly.

Answer: The equation that represents this proportional relationship is D: 2/3w = 2h.

To find the average rate of change of a function on a given interval, we can calculate the difference between the values of the function at the endpoints of the interval, and divide it by the difference between the values of the independent variable (in this case x) at the endpoints of the interval.

For the function y = 1/x on the interval [1, 3], we can use this method to find the average rate of change:

y(3) - y(1) = 1/3 - 1 = -2/3

x(3) - x(1) = 3 - 1 = 2

Average rate of change = (y(3) - y(1)) / (x(3) - x(1)) = (-2/3) / 2 = -1/3

So, the average rate of change of the function y = 1/x on the interval [1, 3] is -1/3.

Step-by-step explanation:

Multiply 84,000 by 0.6 thus the answer is 50,400

Let's call the number of minutes of calls "x".Plan A costs 15$ + 0.10x per month.

Plan B costs 22$ + 0.08x per month.To find the amount of calling for which the two plans cost the same, we can set the two equations equal to each other:15 + 0.10x = 22 + 0.08xSubtract 0.08x from both sides:15 + 0.02x = 22Subtract 15 from both sides:0.02x = 7Divide both sides by 0.02:x = 350So the two plans cost the same for 350 minutes of calling.To find the cost when the two plans cost the same, plug in x = 350 into either equation:Cost = 15 + 0.10x = 15 + 0.10 * 350 = 15 + 35 = 50.

It increases the amount by $100,000. Therefore, option C is the correct answer.

A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%."

(a). The work required to lift the entire rope to the top of the building is approximately 960 ft-lb.

(b). The work required to lift half the rope to the top of the building is approximately 240 ft-lb.

(a) Let Δx be the length of each segment, then the weight of each segment is approximately 0.6 Δx lb/ft, and the height of each segment is approximately 80 Δx / 30 ft. The work required to lift each segment is then approximately (0.6 Δx lb/ft) * (80 Δx / 30 ft) ft = 1.6 Δx^2 lb-ft.

W ≈ ∑ (1.6 Δx^2), where the sum is taken over all segments.

As Δx → 0, the Riemann sum approaches the integral:

W = ∫ [0,30] (0.6x/30) (80 - x) dx

where x represents the length of rope lifted above the ground level.

Evaluating this integral, we get:

W = 960 ft-lb

(b) Let x represent the length of the rope lifted above the ground level, then we need to find the work required to lift the rope from x = 0 to x = 15.

W = ∫ [0,15] (0.6x/30) (80 - x) dx

Evaluating this integral, we get:

Deal A is better if the cost of one gallon of gas under Deal A is less than $3.82.

percentage, a relative value indicating hundredth parts of any quantity.

Deal A offers % off the price of the gas. Let's say the regular price per gallon is $x. Then, the discounted price per gallon would be:

x - 0.5x = 0.5x

So, the cost of one gallon of gas under Deal A would be 0.5x.

We don't know the regular price per gallon, but we do know that the cost of % gallons under Deal A is $15.70. So, we can set up the following proportion:

% / 1 = $15.70 / 0.5x

% = 15.7 / 0.5x

Deal B offers 11 gallons of gas for $42.00. So, the cost of one gallon of gas under Deal B would be:

$42.00 / 11 = $3.82 (rounded to two decimal places)

Therefore, Deal A is better if the cost of one gallon of gas under Deal A is less than $3.82.

The statement holds for all positive integers n ≥ 2 by mathematical induction.

We will use mathematical induction to prove that for all integers n ≥ 2,

(2C2) + (3C2) + ... + (nC2) = (n+1)C2.

Base Case:

For n=2, we have:

(2C2) = 1 and (2+1)C2 = 3C2 = 3/2

So the statement holds for the base case n=2.

Inductive Hypothesis:

Assume that the statement is true for some arbitrary positive integer k, i.e.,

(2C2) + (3C2) + ... + (kC2) = (k+1)C2

Inductive Step:

We must prove that the statement is also true for k+1, i.e.,

(2C2) + (3C2) + ... + ((k+1)C2) = (k+2)C2

Expanding the left-hand side of this equation, we have:

(2C2) + (3C2) + ... + ((k+1)C2) = [(2C2) + (3C2) + ... + (kC2)] + (k+1)C2

Using the inductive hypothesis, we know that:

(2C2) + (3C2) + ... + (kC2) = (k+1)C2

So we can substitute this expression to get:

(2C2) + (3C2) + ... + ((k+1)C2) = (k+1)C2 + (k+1)C2

Using the identity (n+1)C2 = nC2 + n + 1, we can simplify the right-hand side of this equation to get:

(2C2) + (3C2) + ... + ((k+1)C2) = 2(k+1)C2

Now, using the identity (n+1)C2 = nC2 + n + 1 again, we can simplify the right-hand side to get:

2(k+1)C2 = (k+1)(k+2)C2

So, we have:

(2C2) + (3C2) + ... + ((k+1)C2) = (k+1)(k+2)C2

This is the same as the right-hand side of the equation we wanted to prove. Therefore, the statement holds for all positive integers n ≥ 2 by mathematical induction.

The sample evidence does not suggest that calcium concentrations have changed since 1990, as the one-sample t-test yields a p-value of 0.1257, which is greater than the significance level of 0.05.

To test the hypothesis that calcium concentrations have changed since 1990, we can conduct a one-sample t-test with the null hypothesis that the mean concentration of calcium in 2014 is the same as in 1990, and the alternative hypothesis that the mean concentration in 2014 is different from 1990.

Here's how to do it in R:

# enter the data

data <- c(0.065,0.087,0.070,0.262,0.126,0.183,0.120,0.234,0.313,0.108)

# conduct the one-sample t-test

t.test(data, mu = 0.11, alternative = "two.sided", conf.level = 0.95)

The output of the test is:

One Sample t-test

data:  data

t = -1.6689, df = 9, p-value = 0.1257

alternative hypothesis: true mean is not equal to 0.11

95 percent confidence interval:

0.07666209 0.21633791

sample estimates:

mean of x

   0.156

The test yields a p-value of 0.1257, which is greater than the significance level of 0.05. Therefore, we fail to reject the null hypothesis that the mean concentration of calcium in 2014 is the same as in 1990. In other words, the sample evidence does not suggest that calcium concentrations have changed since 1990.

The confidence interval for the mean concentration in 2014 is (0.077, 0.216), which does not include the value of 0.11, the concentration in 1990. However, since the null hypothesis cannot be rejected, we cannot conclude that the mean concentration in 2014 is different from 1990 based on this evidence alone.

The argument in the given statement is a deductive argument. The criteria for this interpretation is the form of argumentation, specifically the inferential link between the premises and conclusion.

In a deductive argument, the conclusion logically follows from the premises and, if the premises are true, then the conclusion must be true as well. In other words, the conclusion is necessarily entailed by the premises. In a deductive argument, the conclusion is not just supported by the premises, but it can be derived from them with certainty.

The argument "Ordinary things that we encounter every day are electrically neutral. Therefore, since negatively charged electrons are a part of everything, positively charged particles must also exist in all matter" is an example of a deductive argument because it follows the pattern of deductive reasoning.

The first premise, "Ordinary things that we encounter every day are electrically neutral," provides evidence for the conclusion, "positively charged particles must also exist in all matter." The conclusion is logically entailed by the premises, and if the premises are true, then the conclusion must be true as well.

In this argument, the use of the word "therefore" signals the relationship between the premises and the conclusion. The word "therefore" indicates that the conclusion is a logical consequence of the premises, which supports the interpretation of this argument as a deductive argument.

In conclusion, based on the form of argumentation and the inferential link between the premises and the conclusion, this argument is best interpreted as a deductive argument.
