In the parallelogram ABCD the value of DF is 13.33 metres or DF = 40/3 metres (rounded to two decimal places).

In the parallelogram ABCD, we can draw a diagonal AC that splits the parallelogram into two congruent triangles, namely, △ABC and △ADC.

Let x be the length of DF. We can use similar triangles to find x.

Notice that △BCE and △DFE are similar triangles, since they share the same angle at E and the angles at B and D are congruent due to opposite angles in a parallelogram. Therefore, we can write the following proportion:

BC/CE = DF/FE

Substituting the given values, we have:

16/8 = x/(20-x)

Simplifying this equation, we get:

2 = x/(20-x)

2(20-x) = x

40 - 2x = x

3x = 40

x = 40/3

Therefore, DF = 40/3 meters or 13.33 meters (rounded to two decimal places).

We can use the principle of inclusion-exclusion to find n(U), which states that for two sets A and B:

n(A union B) = n(A) + n(B) - n(A intersection B)

We can apply this to three sets r, s, and their complements r' and s':

n(U) = n(r union s)

= n(r) + n(s) - n(r intersection s)

= [n(r intersection s') + n(r intersection s)] + [n(s intersection r') + n(s intersection r)] - n(r intersection s)

= [(4 + n(r' intersection s)) + (n(r intersection s') + 7)] - 4

= n(r' intersection s) + n(r intersection s') + 3

= 7 + 3 + 3

= 13

The value of the probability P(A ∪ B) if the events are independent events is  0.55

The formula for the probability of the union of two events is:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Since the events A and B are independent, the probability of their intersection is simply the product of their individual probabilities:

P(A ∩ B) = P(A) × P(B)

Substituting the given values, we have:

P(A ∩ B) = 0.4 × 0.25 = 0.1

Now we can use the formula for the union:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

So, we have

P(A ∪ B) = 0.4 + 0.25 - 0.1

This gives

P(A ∪ B) = 0.55

Therefore, the probability of the union of events A and B is 0.55.

The expected value and standard deviation of x are 1.6 and 0.66, respectively.

Given that:

Jimmy volunteers at events at the hospital each year.

The random variable x is the number of hospital events Jimmy works at each year.

We understand that he does not work for more than two events in a year

So, x can take on the values 0, 1, or 2.

From the question, we have:

Over the past ten years

So, the table is

X P(X)

0 0.1

1 0.2

2 0.7

To find the expected value, we take the sum of the products of x and P(x)

So, we have

E(x) = 0(0.1) + 1(0.2) + 2(0.7)

E(x) = 1.6

To find the standard deviation, we need to first calculate the variance:

Var(X) = E(x^2) - [E(x)]^2

Where

E(x^2) = 0^2(0.1) + 1^2(0.2) + 2^2(0.7)

E(x^2) = 3

So, we have

Var(X) = 3 - (1.6)^2

Var(X) = 0.44

This means that

SD(x) = √0.44

SD(x) = 0.66

Hence, the standard deviation is 0.66

2. D.

3. D.

Step-by-step explanation:

A.  Round both dimensions the nearest whole number. 8 1/3 rounds to 8,     6 3/4 rounds to 7. Multiply these two and your estimate for the tarp area is 56 sq yds. Option C.

B. Convert both mixed numbers to improper fractions. Multiply whole number by divisor and add the dividend. (8*3) + 1 = 25. First number is 25/3.(6*4) + 3 = 27. Second number is 27/4. Multiply these two numbers fractions  and get 225/4. Convert to a mixed number, 56 1/4. Option D.

C. This answer is reasonable. 56 1/4 is pretty close to our estimate of 56 sq yds. Or just choose the option that corresponds to your estimate from part A. Option D.

If A, B, and C lie on a straight line, the sum of angles y, x, and z will be 180 degrees:

y + x + z = 180

Substituting the values given in the problem:

95 + x + 330 = 180

Simplifying:

425 + x = 180

Subtracting 425 from both sides:

x = -245

Therefore, x is -245 degrees.

However, since x represents an angle on a straight line, we can add 180 degrees to get an equivalent angle:

x + 180 = -245 + 180 = -65

Therefore, x is -65 degrees.

The lowest common denominator, 20, can be used to represent any fraction that can be stated as a ratio of integers with factors of 2 and 5 in the denominator. eg. 1/4, 1/2, 2/5 and 7/10

To find all the fractions that have 20 as the lowest common denominator, we need to identify all the prime factors of 20, which are 2, 2, and 5.

Then, we can express each fraction with these prime factors in the denominator, by multiplying the numerator and denominator by the missing factors. For example, for the fraction 1/4, we need to multiply both the numerator and denominator by 5 to get:

1/4 = 5/20

Similarly, for the fraction 3/5, we need to multiply both the numerator and denominator by 2 to get:

3/5 = 6/10 = 12/20

By doing this for all fractions, we can express them with the same denominator of 20. Here are some examples:

1/4 = 5/20

3/5 = 12/20

1/2 = 10/20

2/5 = 8/20

7/10 = 14/20

Answer: To find the total area of the grass that Yuri's dad needs to fertilize, we need to calculate the area of the back yard and the area of the front yard, and then add them together.

Area of the back yard:

The back yard measures 55 feet by 30 feet, so the area is:

55 feet x 30 feet = 1650 square feet

Area of the front yard:

The front yard is a square with a length of 42 feet on each side, so the area is:

42 feet x 42 feet = 1764 square feet

Total area:

To find the total area, we add the area of the back yard and the area of the front yard:

1650 square feet + 1764 square feet = 3414 square feet

Therefore, Yuri's dad needs to fertilize a total area of 3414 square feet.

A proportional connection exists when two values may be expressed as y = kx, where k is a constant. To discover which ordered pairings have a proportionate connection with (0.2, 0.3).

We must find a value of k for each pair that makes this equation true. Let us begin with option A: (1.2, 2.3). If we wish to represent this combination as y = kx, we must discover the value of k that results in 2.3 = k. (1.2). When we solve for k, we get: k = 2.3 / 1.2 ≈ 1.92 As a result, (1.2, 2.3) does not have a proportionate connection with (0.2, 0.3) since the value of k is different for both couples. This procedure can be repeated for each of the others. options. Option B: (2.7, 4.3) yields: k = 4.3 / 2.7 ≈ 1.59 Option C: (3.2, 4.8) yields: k = 4.8 / 3.2 = 1.5 Option D: (3.5, 5.3) yields: k = 5.3 / 3.5 ≈ 1.51 Option E: (5.2, 7.8) yields: k = 7.8 / 5.2 = 1.5 As a result, alternatives C and E are proportional to (0.2, 0.3) since they can be represented in the form y = kx with the same k value. k = 1.5 in both situations.

The initial amount of salt in the tank is 60 kg, calculated using the formula M = ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank.

Initially, the tank contains 60 kg of salt and 2000 liters of water. The amount of salt in the tank can be calculated using the formula M=ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank. The density of salt is 2270 kg/m3. Assuming the tank has a constant volume, the mass of the salt in the tank is 60 kg.

The amount of salt in the tank changes due to the addition of pure water and mixing of the solution. The amount of salt in the tank at any given time can be calculated using the formula M=ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank. The rate at which the salt is added to the tank is equal to the rate at which the salt-water solution is drained from the tank.

Therefore, the rate of change of the mass of the salt in the tank is equal to 8 liters/minute of pure water entering the tank minus 4 liters/minute of salt-water solution draining from the tank. Thus, the amount of salt in the tank initially is 60 kg.

The caterpillar touches 15 points with two integer coordinates, including the start point (-3, -4) and the end point (25, 38).

What is co-ordinate geometry ?

Coordinate geometry is a branch of mathematics that deals with the study of geometry using the principles of algebra. In coordinate geometry, geometric figures are represented using algebraic equations and analyzed using techniques from algebra and calculus.

The caterpillar moves from (-3, -4) to (25, 38) in a straight line. We can find the equation of the line passing through these two points using the slope-intercept form of the equation of a line:

y - (-4) = (38 - (-4))/(25 - (-3)) * (x - (-3))

y + 4 = 42/28 * (x + 3)

y = 3/2 * x + 19

The caterpillar touches a point with two integer coordinates whenever x and y are both integers. To find these points, we can substitute integer values for x and solve for y. Since the slope of the line is 3/2, every time x increases by 2, y increases by 3.

Starting from x = -3, we can list the integer values of x that the caterpillar touches:

-3, -1, 1, 3, 5, ..., 25

For each value of x, we can compute the corresponding value of y using the equation of the line:

y = 3/2 * x + 1

For example, when x = -3, y = 3/2 * (-3) + 19 = 14.5, which is not an integer. When x = -1, y = 3/2 * (-1) + 19 = 17.5, which is also not an integer. However, when x = 1, y = 3/2 * 1 + 19 = 20, which is an integer. Similarly, we can find the integer values of y for all the other values of x.

Therefore, the caterpillar touches 15 points with two integer coordinates, including the start point (-3, -4) and the end point (25, 38).

The probability of getting at least one "r" of the alphabet if letters of the alphabet are selected at random is 1/1.

The reason for this is that if any letter of the alphabet is selected at random, the probability of getting an "r" is 1/26, or 0.0385. Since letters can be used more than once, this probability remains the same regardless of how many letters are selected. Thus, the probability of getting at least one "r" of the alphabet if letters of the alphabet are selected at random is 1.

In summary, the probability of getting at least one "r" of the alphabet if letters of the alphabet are selected at random is 1. This is because, when a letter is selected at random, each letter has an equal chance of being chosen (1/26), and since the probability of selecting an "r" remains the same regardless of how many letters are selected, the probability of getting at least one "r" is also 1.

Donovan scored 6 points, Jeremy scored 18 points, and Kolby scored 12 points.        

Let's denote the number of points scored by Donovan as "D".    

According to the problem, Jeremy scored triple the number of points as Donovan, so he scored 3D points.

Similarly, Kolby scored double the number of points as Donovan, so he scored 2D points.

We also know that the total number of points scored by all three boys is 36. So we can write an equation:

Simplifying this equation, we get:

6D = 36

Dividing both sides by 6, we get:

D = 6

So Donovan scored 6 points.

Using the values we found for Donovan's score, we can find the scores of Jeremy and Kolby:

Jeremy scored 3D = 3(6) = 18 points
