Answer:

The dispersion among sample means is less than the dispersion among the sampled items themselves because:______

b. Very large values are averaged down

Step-by-step explanation:

The sample means represent average values obtained from both large and moderate values.  Through the process of averaging, the data values obtained as the sample means are much closer to the true values.  This is why the dispersions among the sampled items will be larger than the dispersions among the sample means.  Sample dispersions describe how spread out the data values are on the number line.

The domain of the rational expression (6-x)/(4x+20) is all real numbers except x = -5.

To find the domain of a rational expression, we need to identify any values of x that would result in division by zero. Division by zero is undefined in mathematics
In this case, we need to set the denominator, 4x+20, equal to zero and solve for x:
4x + 20 = 0
Subtract 20 from both sides:
4x = -20
Divide both sides by 4:
x = -5
Therefore, the value x = -5 makes the denominator zero.
Now, we need to consider the values of x for which the denominator is not zero. Since the denominator is a linear expression (a polynomial of degree 1), it is defined for all real numbers except x = -5.
So, the domain of the rational expression (6-x)/(4x+20) is all real numbers except x = -5.

The graph which represent the function f ( x ) = 4 [ x ] is graph B

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 4 [ x ]

And , function f(x) = 4[x] represents the greatest integer function, which returns the largest integer less than or equal to x

The graph of the greatest integer function consists of horizontal segments, with jumps at the integers. Since the function is multiplied by 4 in this case, the distance between the jumps will be 1/4 of the original distance.

Hence , the graph is Option B

Using Pythagoras theorem, The missing side of the right triangle is 4,9 mm long.

Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle. The hypotenuse in this example is the longest side because it is located across from the 90° angle. A right triangle's positive integer sides (let's say sides a, b, and c) are squared to produce a Pythagorean triple equation.

Right triangles are what the provided triangle is.

The Pythagorean Theorem is used:

\(a^{2} + b^{2} = c^{2}\)

\((5)^{2} + (7)^{2} = c^{2}\)

25 + 49 =\(c^{2}\)

c = 4.9

Hence, the missing side of the right triangle is 4,9 mm long.

Answer:

We conclude that inequality describes all possible lengths of AB

Option C is true.

Step-by-step explanation:

We know that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Now, checking the interval of the length of the side 'x', such as:

24 + 11 = 35

24 - 11 = 13

so the possible lengths of the side 'x' will be:

13 < x < 35

Therefore, we conclude that inequality describes all possible lengths of AB

Hence, option C is true.

Dan will spend between $40 and $45 on candy. The inequality for c is:

$40 ≤ c ≤ $45.

Dan will spend a minimum of $40 on candy if he purchases at least 8 pounds of candy at a cost of $5 per pound. We need to determine the maximum amount he could spend because he might purchase more candy than 8 pounds.

Say Dan purchases x pounds of chocolates. Therefore his sweets expenditure will be c = 5x dollars. He'll purchase at least 8 pounds of sweets, so we can say:

x ≥ 8

We must take the possibility that Dan may purchase a decimal number of pounds of candy when determining the upper bound of x. Consider the case when he purchases y pounds of sweets, where y is a decimal number such that 0 y 1. then, his

c = $5y in money

He'll purchase at least 8 pounds of sweets, so we can say:

y + 8 ≥ x ≥ 8

We must determine the highest feasible value of y in order to determine the upper bound of c. The closest full number to 8 + 1 = 9 is when Dan purchases just under 9 pounds of sweets, which is the maximum value of y. Hence, we can write:

y = 9 - 8 = 1

The inequality for c is as follows:

c = 5y ≤ c ≤ 5x 40 ≤ c ≤ 5(9) = 45

Dan will therefore spend $40 to $45 on candy. For c, the inequality is:

$40 ≤ c ≤ $45.

We can actually see here that the triangle ABC is an isosceles triangle. This is because two sides of the triangle are equal.

An isosceles triangle is actually a geometric shape having three sides, two of which are equal in length. Consequently, two of the angles that are across from those sides are also equal.

In order to prove that the triangle is an isosceles triangle, we will find the following:

Distance between  vertices A and B:

AB = √((8-5)² + (8-3)²) = √(3² + 5²) = √34 = 5.83mm

Then, we also find the distance between vertices B and C:

BC = √((11-5)² + (3-3)²) = 6mm

Finally, we find the distance between vertices A and C:

AC = √((11-8)² + (3-8)²) = √(3² + 5²) = √34  = 5.83mm

Thus, we see here that AB and AC are actually equal which makes the triangle an isosceles.

Answer:

One possible function that meets the requirements is \(f(x) = 5\, \sin((1/2)\, x + (\pi / 2))\).

Step-by-step explanation:

In general, a sinusoidal function is of the form \(f(x) = A\, \sin(\omega\, x + \varphi) + D\), where \(A\), \(\omega\), \(\varphi\), and \(D\) are constants.

The constant \(A\) determines the amplitude of this sinusoidal function. The amplitude is \((1/2)\) the vertical distance between maxima and minima. In this question, the vertical distance between maxima and minima is \((5 - (-5)) = 10\), such that \(A = (1/2) \, (10) = 5\).

The constant \(D\) determines the midpoint between maxima and minima. In this question, the midpoint between minima (\(y = (-5)\)) and maxima (\(y = 5\)) is \((1 / 2)\, ((-5) + 5) = 0\). Hence, \(D = 0\).

The constant \(\omega\) determines the period of this sinusoidal function. The period of \(f(x) = A\, \sin(\omega\, x + \varphi) + D\) is \((2\, \pi / \omega)\), such that:

In this question, assume that there is no minima between \(x = 0\) and \(x = 2\,\pi\) (exclusive). Hence, \((\pi / \omega) = 2\,\pi\), and \(\omega = (1/2)\).

The constant \(\varphi\) shifts the sinusoidal function horizontally. After finding \(A\), \(D\),  and \(\omega\), substitute in a point on the graph of this function to find the value of \(\varphi\!\). For example, since \((0,\, 5)\) is a point on the graph of \(f(x) = A\, \sin(\omega\, x + \varphi) + D = 5\, \sin((1/2)\, x + \varphi)\):

\(5\, \sin((1/2)\, (0) + \varphi) = 5\).

\(5\, \sin(\varphi) = 5\).

One possible value of \(\varphi\) would be \((\pi / 2)\).

Hence, one possible formula satisfying the requirements is \(f(x) = 5\, \sin((1/2)\, x + (\pi / 2))\).

The circled portion in the confidence interval formula p ± z represents the Margin of Error, which plays a crucial role in interpreting the range of plausible values for the population parameter.

In the confidence interval formula p ± z, the circled portion represents the Margin of Error.

The Margin of Error is a critical component of a confidence interval and quantifies the level of uncertainty in the estimate.

It indicates the range within which the true population parameter is likely to fall based on the sample data.

The Margin of Error is calculated by multiplying the critical value (z) by the standard deviation of the sampling distribution.

The critical value is determined based on the desired level of confidence, often denoted as (1 - α), where α is the significance level or the probability of making a Type I error.

The Margin of Error accounts for the variability in the sample and provides a measure of the precision of the estimate.

It reflects the trade-off between the desired level of confidence and the width of the interval.

A larger Margin of Error indicates a wider confidence interval, implying less precision and more uncertainty in the estimate.

Conversely, a smaller Margin of Error leads to a narrower confidence interval, indicating higher precision and greater certainty in the estimate.

Answer:

z(s) is in the rejection region we reject H₀     μ₁  = μ₂  and support the claim that at CI 95 % the means of the two groups differs

Step-by-step explanation:

Sample 1:

Sise sample   n₁  =  115

μ₁  = 169,9 mmHg

σ₁  = 24,8 mmHg

Sample 2:

Sise sample   n₂  =  235

μ₂  = 163,3 mmHg

σ₂  = 25,8 mmHg

We can develop a test hypothesis for differences in means to investigate if the mean peak systolic blood pressure differs between these two groups

We will choose CI = 95 %   then significance level  α  = 5 %

α = 0,05     α/2 = 0,025

z(c) for 0,025 is from z-table   z(c) = 1,96

Test Hypothesis:

Null Hypothesis                                  H₀           μ₁  = μ₂

Alternative Hypothesis                      Hₐ            μ₁  ≠ μ₂

The alternative hypothesis tells us that the test is a two-tail test.

z(s)  =  ( μ₁  - μ₂ ) / √ σ₁²/n₁  + σ₂²/n₂

z(s)  = ( 169,9  -163,3 ) / √ (24,8)² /115   +  ( 25,8)²/235

z(s)  =  6,6  / √5,35 + 2,83

z(s)  =  6,6  / 2,86

z(s) = 2,30

Comparing  |z(c)|    and  |z(s)|

z(s) > z(c)

z(s) is in the rejection region we reject H₀     μ₁  = μ₂  and support the claim that at CI 95 % the means of the two groups differs

Number of 20-cent coins in the box are 33.

1. Let's assume the number of 20-cent coins to be x and the number of 50-cent coins to be y.

2. We can set up two equations based on the given information:

  - x + y = 54   (since the total number of coins in the box is 54)

  - 0.20x + 0.50y = 20.70   (since the total value of all the coins is $20.70)

3. We can multiply the second equation by 100 to get rid of the decimals:

  - 20x + 50y = 2070

4. Now, we can use the first equation to express y in terms of x:

  - y = 54 - x

5. Substitute the value of y in the second equation:

  - 20x + 50(54 - x) = 2070

6. Simplify and solve for x:

  - 20x + 2700 - 50x = 2070

  - -30x = -630

  - x = 21

7. Substituting the value of x back into the first equation:

  - 21 + y = 54

  - y = 33

8. Therefore, there are 21 20-cent coins and 33 50-cent coins in the box.
