Answer:

The quotient of 24 and d would be [tex]\frac{24}{d}[/tex]

Step-by-step explanation:

Quotient is the answer of a division problem. So, you would divide 24 by d.

If x = 5.764764764…, then 1000x = 5764.764764764…, so that

1000x - x = 5764.764764764… - 5.764764764…

999x = 5759

x = 5759/999

a. False. The sample is 46%. We are 95% that the proportion of the population is between 43% and 49%.

b. True, this is the correct interpretation of a confidence interval of proportions.

c. False. The confidence interval does not say anything about the proportion of samples, just about the population.

d. False. As the confidence level decreases, so does z, which means that the margin of error decreases.

In a sample with a number n of people surveyed with a probability of success of, and a confidence level of, we have the following confidence interval of proportions.

In which

z is the score that has a p-value of.

The margin of error is:

So the confidence interval can be written as:

Interpreting a confidence interval:

x% confidence interval between (a,b) means that we are 95% sure that the true proportion of the population is between a and b.

In this problem, we have that:

95% confidence interval between (43%, 49%).

a. We are 95% confident that between 43% and 49% of Americans in this sample support the decision of the U.S. Supreme Court on the 2010 healthcare law.

False. The sample is 46%. We are 95% that the proportion of the population is between 43% and 49%.

b. We are 95% confident that between 43% and 49% of Americans support the decision of the U.S. Supreme Court on the 2010 healthcare law.

True, this is the correct interpretation of a confidence interval of proportions.

c. If we considered many random samples of 1,012 Americans, and we calculated the sample proportions of those who support the decision of the U.S. Supreme Court, 95% of those sample proportions will be between 43% and 49%.

False. The confidence interval does not say anything about the proportion of samples, just about the population.

d. The margin of error at a 90% confidence level would be higher than 3%.

False

As the confidence level decreases, so does z, which means that the margin of error decreases.

Answer:

Step-by-step explanation:

y - 1 = -9/2 (x + 7)

Distribute -9/2:

y - 1 = -9/2x - 63/2

Add 1 on both sides to isolate y:

(y - 1) + 1 = (-9/2x - 63/2) + 1

y = -9/2x -61/2

A line parallel to another has the same slope as that line so both slopes are -9/2.

M = -9/2

The order of the points starting with a and going clockwise around the circle is;

a ⇒ c ⇒d ⇒b

Here,

Four points, a, b, c, and d, lie on a circle having a circumference of 17 units.

b is 5 units counterclockwise from a.

c is 3 units clockwise from a.

d is 11 units clockwise from a and 6 units counterclockwise from a.

We have to find, The order of the points starting with a and going clockwise around the circle.

What is Circumference of circle?

The circumference is the distance around a circle or any curved geometrical shape.

Now,

b is 5 units counterclockwise from a.

b ⇒ a

c is 3 units clockwise from a.

b ⇒ a ⇒ c

d is 11 units clockwise from a and 6 units counterclockwise from a.

d ⇒ b ⇒a ⇒ c ⇒d

So, when we draw all points on circle we get;

The order of the points starting with a and going clockwise around the circle is;

a ⇒ c ⇒d ⇒b

This is shown in figure.

Step-by-step explanation:

The equation of the parabola in vertex form is y + 8 = 2 · (x - 2)². The factored form of the equation of the parabola is y = 2 · x · (x - 4).

Herein we find a representation of a quadratic function on a Cartesian plane, whose formula in vertex form is presented below:

y - k = C · (x - h)²

Where:

By direct inspection we find that the equation of the parabola has a vertex at (h, k) = (2, - 8) and the point (x, y) = (4, 0). Then, the vertex constant is:

C = (y - k) / (x - h)²

C = (0 + 8) / (4 - 2)²

C = 8 / 4

C = 2

Then, the equation of the parabola in vertex form is y + 8 = 2 · (x - 2)². The factored form of the equation is determined by algebra:

y + 8 = 2 · (x - 2)²

y = 2 · (x - 2)² - 8

y = 2 · (x² - 4 · x + 4) - 8

y = 2 · x² - 8 · x + 8 - 8

y = 2 · x² - 8 · x

y = 2 · x · (x - 4)

The factored form of the equation of the parabola is y = 2 · x · (x - 4).

Using translation concepts, the series of transformations that shows that pentagon A is congruent to pentagon B is:

B. Rotate pentagon A 90° clockwise about the point (1, 1), reflect it over the x-axis, and translate it 3 units to the left.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, we have that the Pentagons have different orientations, meaning that it was rotated, eliminating options A and D.

For the vertices to reach the position they reached in Pentagon B, there had to be a shift left, and before the shift left, the Pentagon must have been entirely at the fourth quadrant, meaning that it was reflected about the point (1,1), and option B is correct.

Step-by-step explanation:

Here are the missing amounts :

A = $2100

B = $300

C =  $50

D =  $270

E = $945

F = $1,345

Receipts represents income to the company. It is a source of cash inflow. Expenses represents cash outflow. Net cash flow is the difference between receipts and expenses. Cumulate balance is the sum of the net cash flow of the previous periods and the net cash flow of the present period.

A = Net cash flow + expenses

1975 + 125 = 2100

B = Receipts - expense

$2225 - $1925 = $300

C =  Receipts - expense

$2050 - $2000 = $50

D = Net cash flow = $270

E = cumulative balance in April + net cash flow in May

$570 + $375 = $945

The three inequalities that satisfies all the points in the unshaded region of the graph of inequalities are;

The three inequalities that satisfies all the points in the unshaded region are;

1) The inequality that represents the unshaded region to the left of the vertical dashed line at x = 5 is found as follows;

A region to the left of a vertical dashed line in inequality is represented by the less than or equal to symbol, ≤. The region to the right is represented by ≥

The region to the left of the dashed line, x = 5 is therefore;

2) The region located below the dashed line y = 10 is represented by the inequality;

3) The slope, m, of the dashed line that extends from point (0, 10) to point (5, 0) is given by the equation;

m = (0 - 10)/(5 - 0) = -2

The equation of the line is therefore;

y - 0 = -2 × (x - 5) = -2•x + 10

y = -2•x + 10

Which gives;

y + 2•x = 10

2•x + y = 10

The inequality that represents the region to the right of the line 2•x + y = 10 is therefore;

2•x + y ≥ 10

The compound inequality, that represents the unshaded region is therefore;

Yes it would be better to use breaking apart in the distributive property or compensation to find the product of 5 x 328 .

what is distributive property?

This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding or substracting the results together .like in subtraction  A(B-C)= AB-AC

In other words, an equation of the type A (B+C) can be solved as A (B+C) AB+AC in accordance with the distributive property.

This characteristic also holds for subtraction.

5 x 328

= 5(300+28)

= 5 x 300 + 5 x 28
