The coordinates of triangle ABC after dilation are; (-6, -3), (0, 9) and (3, 3)

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

Given that, a triangle ABC with coordinates, A (-2, -1) B (0, 3) C (1, 1)

This triangle is dilated by a scale factor of 3,

SInce, the scale factor is greater than 3, therefore, dilation shows an enlargement.

The rule of dilation is given by;

(x, y) → (kx, ky), where k is dilation factor.

Let triangle ABC is dilated to form triangle A'B'C'

Therefore, the coordinates of triangle A'B'C' are;

A' = 3(-2, -1) = (-6, -3)

B' = 3(0, 3) = (0, 9)

Since the angles in DBC and BDA are equal, we have:

What is the Angle-Angle Similarity Theorem?

The Angle-Angle Similarity Theorem, also known as the AA Similarity Theorem, states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are similar.

Given: AD // BC, AB // CD

To prove: DBC =~ BDA

From the given, we have AD // BC and AB // CD.

This means that AD is parallel to BC and AB is parallel to CD.

Since AB is parallel to CD, corresponding angles are equal.

Let the angle BCD = x.

Then, angle BAD = x.

Since AD // BC, corresponding angles are equal.

Let the angle DCB = y.

Then, angle DAC = y.

Now, we can see that angle BDA + angle DAC = y + x.

And angle DBC + angle DCB = y + x.

Since the sum of the angles in a triangle is 180 degrees,

angle BDA + angle DAC + angle DBC = 180.

So, y + x + y + x = 180.

Therefore, 2y + 2x = 180.

And, y + x = 90.

Since the angles in DBC and BDA are equal, we have:

DBC =~ BDA

The equation for the probability of a certain number of bicycle accidents occurring in the next four months is [tex]P(x) = (x^3 - 3x^2 + 5x - 3)/24[/tex], where x is the number of accidents. To solve this equation with R, we can use the dbinom() function which is used to calculate the binomial cumulative distribution function. We set the size parameter to 4 (the number of months) and the probability parameter to 0.25 (the probability of a bicycle accident occurring at the intersection in a single month). The code is dbinom(3:5, size=4, prob=0.25). This yields an answer of 0.3125, meaning that the probability of 3 to 5 bicycle accidents occurring in the next four months is 0.3125.

The required value of angle x for a given hexagon is 20°.

What is a hexagon?

In terms of geometry, a hexagon is a closed, six-sided polygon in two dimensions. Six vertices and six angles make up a hexagon. The words "hexa" and "gonio" both refer to six.

A hexagon's internal angles add up to 720°. All of the sides and interior angles of a regular hexagon are the same lengths.

Given, the interior angles of a hexagon are 7x°, 7x°, 4x°, 7x°, 7x°, and 4x° respectively.

So, the sum of interior angles = 720°

or, 7x° + 7x° + 4x° + 7x° + 7x° + 4x° = 720°

or, 36x° = 720°

or, x = 720/36

or, x =20°

Hence, the required value of x is 20°.

The financial planner invested $4,737.50 in the mini-mall development plan and $1,012.50 in the savings account.

The amount invested in the savings account is equal to the total amount invested minus the amount invested in the mini-mall development plan. We can express this as an equation:

Total Investment - Investment in Mini-Mall Development Plan = Investment in Savings Account

Substituting the values given in the problem, we get:

$5,750 - Investment in Mini-Mall Development Plan = Investment in Savings Account

To solve for the Investment in Mini-Mall Development Plan, we need to use the combined interest earned for the first year. We can express this as an equation:

Interest Earned = (Investment in Savings Account x Interest Rate) + (Investment in Mini-Mall Development Plan x Interest Rate)

Substituting the values given in the problem, we get:

$475 = (Investment in Savings Account x 0.02) + (Investment in Mini-Mall Development Plan x 0.12)

Solving for Investment in Mini-Mall Development Plan, we get:

Investment in Mini-Mall Development Plan = ($475 - (Investment in Savings Account x 0.02))/0.12

Substituting the values given in the problem, we get:

Investment in Mini-Mall Development Plan = ($475 - ($5,750 - Investment in Mini-Mall Development Plan x 0.02))/0.12

Solving for Investment in Mini-Mall Development Plan, we get:

The second segment crosses the x-axis at (1.5, 0), and the slope of the segment is -1

The area under any probability density curve is always 1 and it is used for finding out the probabilities for any random variable X taking a certain range of values.

Let the second segment crosses at (a,0) on the X-axis:

The area under the density curve is 1.

the given fig can be divided into a rectangle and a triangle by dropping a line from the point (0.5, 1) in the x-axis.

The coordinate point of the second segment at the x-axis:

Now,

1*0.5+1/2*1*(a-0.5)=1

1+(a-0.5)=2

a-0.5=2-1

a=1+0.5

a=1.5

Thus the second segment crosses the x-axis at (1.5, 0)

The slope of that segment c:

The slope  of that segment=y₂-y₁/x₂-x₁

By considering the points (0.5, 1) and (1.5, 0)

We will have the slope as:

m=0-1/1.5-0.5

m=-1/1

m=-1

the equation of the line containing this segment:

The line passes from the point (0.5, 1)

y=mx+b is used to find the value of the intercept

so, substitute the values in the equation:

1=(-1)*0.5+b

1=-0.5+b

b=1.5

so, the equation for that line segment is

y=-x+1.5

x+y=1.5

To calculate the probability P(X > 1):

[tex]P(X > 1)=\int\limits\limits^1_1 {y} \, dx \\P(X > 1)=\int\limits^1_1 {(-x+1.5)} \, dx[/tex]

[tex]P(X > 1)=[\frac{-x^2}{2}+1.5x]_1^1^.^5\\\\P(X > 1)= (\frac{(-1.5)^2}{2} +1.5*1.5)-(\frac{-1^2}{2}+1.5*1)\\[/tex]

Answer:

The answer is 3.2 x 10-21.

Step-by-step explanation:

To solve this problem, we need to use the rules of exponents. The first step is to calculate the exponents for each number.

For 9 × 104, the exponent is 3 (9 × 104 = 90000).

For 3,000,000, the exponent is 2 (3,000,000 = 3000000).

For 0.00243, the exponent is -3 (0.00243 = 0.00000243).

Now, we can calculate the answer by multiplying the exponents:

3 × 2 × (-3) = -6

Then, we need to multiply the numbers together to get the final answer:

(9 × 104)² × (3,000,000)² × (0.00243) = 9 x 10-6 x 9 x 10-12 x 0.00243 = 3.2 x 10-21.

Yes, it would be unusual to get a score of 0 on a binomial distribution with a mean of 2.5 and a standard deviation of 1.4. This is because the expected value of such a distribution is much higher than 0. The binomial distribution is a type of probability distribution which is used to describe the probability of a discrete event occurring a certain number of times in a given number of trials. The mean of the binomial distribution is the expected value of the events, while the standard deviation is a measure of how much the values of the events vary from the expected value. In this case, the expected value is 2.5, and the standard deviation is 1.4. This means that the probability of getting a score of 0 is quite low, since the expected value is so much higher than 0. Therefore, it would be considered unusual to get a score of 0 on this binomial distribution.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200

⇒ 0.5x = 1200

⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400

250% of p = 2400

2.5p = 2400

p = 2400 / 2.5 = 960.
