The percent of increase or decrease = change/original x 100%

Since the original price of the watch is $39

Since its price now is $17.50, then

The change of the price = 39 - 17.50 = 21.50 dollars

The percentage of decrease = 21.50/39 x 100%

The percentage of decrease = 55.1282

Round it to the nearest tenth

The percentage of decrease is 55.1%

First i will draw the original point in red

the rotation of 180° will give us the point (3,-4) the blue point

next, we reflect this point in the y-axis, the green point

if we see only the red point and the green point the transformation is equivalent to a reflection in the x-axis

the correct answer is 1

Rate of Jenny = 1/ 8.4 minutes

The time they will take will be the inverse of this, thus:

So, let's calculate it:

That is around 5.15 minutes.

Answer:

150 degrees

Explanation:

Vertical angles are equal, therefore:

Next, angles 1 and 5 are corresponding angles.

Corresponding angles are equal, therefore:

The measure of angle 1 is 150 degrees.

The shape of the distribution A is Negatively skewed.

What is a negatively skewed distribution?\

A negatively skewed distribution sometimes referred to as a left-skewed distribution, is a type of distribution where more values are concentrated on the right side (tail) of the distribution graph and the left tail of the distribution graph is longer.

The idea of skewness is used in finance to analyze the distribution of investment returns. An investor may anticipate frequent tiny wins and a few significant losses, according to the distribution's negative skewness. In fact, traders frequently use trading methods that are based on distributions that are negatively skewed.

Answer:

Step-by-step explanation:

We know supplementary angles add up to 180°:

Find the missing one:

Correct choice is C.

Answer:

Explanation:

We know that the ratio of Helga's savings to Maurice's savings is 8:3 and the ratio of Maurice's savings to Nora's savings is 3:4.

It means that if Helga has $8, Maurice has $3 and Nora has $4

In the same way, we can multiply one quantity by 2, and all the quantities will be multiplied by 2, so if Helga has $16, Maurice has $6 and Nora has $8

Because:

$8 x 2 = $16

$3 x 2 = $6

$4 x 2 = $8

So, following the same logic, we can complete the table as:

Therefore, the complete table is:

A rhombus is a two-dimensional shape and is also characterized as a special parallelogram. It has four equal sides, with the opposite angles being equal to each other, whereas its adjacent angles are supplementary.

A rectangle is a also two-dimensional shape. It has four equal angles and four vertices. All the four angles of a rectangle measure 90°.

Rhombuses and Rectangles have the following differences:

1) A rhombus has four equal sides while in a rectangle, the opposite sides are equal.

2) The diagonals of a rhombus bisect each other at 90° while the diagonals of a rectangle bisect each other at different angles.

From here we can see that X=300 falls below the mean.

So we can use this formula:

Answer: X falls below the mean by 23.688%

The first step in simplifying the inequality is to divide both sides by -14:

Since we are dividing both sides by a negative number, the inequality reverses direction, and hence it becomes

This is the farthest we can go in simplifying the inequality; therefore, the above inequality is our answer

For the first equation:

y = (x + 5)(x + 1)

apply distribution property:

y = (x + 5)(x) + (x + 5)(1)

y = x·x + 5·x + x·1 + 5·1

y = x² + 5x + x + 5

y = x² + 6x + 5

For the second equation:

y = (x + 3)² - 4

use the fact that (a + b)² = a² + 2ab + b², for the term (x + 3)², then, you have:

y = x² + 2·x·3 + 3² - 4

y = x² + 6x + 9 - 4

y = x² + 6x + 5

The third equation is already in the convenient form.

Then, you can notice that all three equations are the same equations.

Answer

a = b

a + c = b + c (Addition Property of Equality)

This operation is True.

Explanation

If we are told that

a = b

Adding the same number to both sides of an equation is called the Addition Property of Equality.

And it produces the same number on both sides after this operation.

a = b

Add c to both sides

a = b

a + c = b + c (Addition Property of Equality)

This operation is True.

Graphing the triangle DEF, we have:

Now, translating the triangle 4 units right and 3 units down, we have the new vertices:

Graphing the triangle D'E'F', we have:

a. In order to determine how much soap material is used for each bar of soap, consider that the shape of the bar is a cylinder, then, use the folowing formula for the volume of a cylinder:

V = π r² h

where r is the radius of the base and h is the height.

The diameter is 5 cm, then, the radius is r = d/2 = 5 cm/2 = 2.5 cm

The height is h = 2 cm

replace the previous values into the formula for V:

V = (3.14)(2.5 cm)²(2 cm)

V = 39.25 cm³

Hence, 39.25 cm³ of soap material is used to make each bar.

b. In this case it is necessary to calculate the suface area of the plastic used. As before, take into account that the bar has a cylindrical shape. Then, use the following formula for the surface area of a cylinder:

S = 2πr² + 2πrh

replace the values of the parameters to find S:

S = 2π(2.5 cm)² + 2π(2.5cm)(2cm)

S = 70.68 cm²

Hence, 70.68 cm² of plastic is required to wrap each bar

c. Take into account that the soap must be stacked no more than 5 bars high, and that the company wants to ship a minimum of 60 bars.

If there are 5 bars high x 3 bars length, in one face of the box you have 15 bars. Moreover, if there are 4 bars width, then, you have a total of 15x4 = 60 bars in one box, which is what the company wants.

The height of the box is given by 5 times the height of one bar (because there are 5 bars high). The length is given by 3 times the diameter of one bar and the width of the box is given by 4 times the diameter of one bar:

height of the box = 5(2 cm) = 10 cm

length of the box = 3(5 cm) = 15 cm

width of the box = 4(5 cm) = 20 cm

d. First, calculate the volume of the box, as follow:

V = h x l x w = (10 cm)(15 cm)(20 cm) = 3,000 cm³

take into account the conversion 1,000 cm³ = 1 L, then, the capacity of the box is:

V = 3,000 cm³ = 3L

The mean absolute deviation (MAD) is a statistical measure of how much the different data points "move away" from the mean of the data set. In this case the weights of the bears have been given, the mean has been calculated and the MAD is derived by deducting each data point from the mean. The MAD has been given already by the way. Some data points fall below the mean while some are above it. but whatever the difference is, you'll have to take the "absolute value" that is positive value only. For example, the mean weight of the black bears is 299, and the weight of the first black bear is 102, that gives you adifference of 197. note that the result should be negative 197 (-197) but we are interested in the absolute values only.

Same way you find the absolute deviation for the other data points and you have, 197, 148, 51, 43, 154, and 199. Sum up these numbers and divide by the number of observed data (number of black bears) and you have 792 divided by 6 which gives you 132. This means the mean absolute deviation of the observed data is 132 as compared to the mean which is 299.

If you compare the MAD of the black bears with that of the grizzly bears, you would see that the MAD of the grizzly bears is more varied, because 104 2/3 moves further away from 419 than the MAD of the black bears which is 132 moving away from 299.
