which statement can you use to conclude that quadrilateral xyzw is a parallelogram

The formula that is used to calculate the midpoint for the given two point is written as ( (x₁ + x₂)/2 , (y₁ + y₂)/2).

Mid point:

Midpoint refers the point on a line that is at an equal distance from either end.

Given,

Here we have to explain the concept of midpoint in a simple manner.

According to the definition, midpoint refers the central point between the two points.

So, in a simple manner we have said that the mid point is calculated by finding the average of the two given point.

For example, (x₁, y₁) and (x₂, y₂) are the points, then the midpoint (xₙ, yₙ) is calculated by using the formula,

(xₙ, yₙ) = ( (x₁ + x₂)/2 , (y₁ + y₂)/2)

Similarly, if one point and the midpoint is given, then the another point is calculated by apply the remaining point as (x, y) and solve it accordingly, then we can get the value of it.

The number of bananas Bruce can eat in 4 weeks is 70 bananas

From the question, we are to calculate the number of bananas Bruce can eat in 4 weeks.

From the given information,

Bruce can eat 2 1/2 bananas per day

First, we will determine the number of days there are in 4 weeks

Amount of money present in Juan's account when she is 18 years old is $2,284.73

When Juan is 12 years old ;

Given P = principal = $ 2000

r = interest rate = 2.3 %

t = number of periods = 2

To start, multiplying R percent by 100 gives us 2.3%/100, or 0.023 each year.

Simply converting time into years, 2 months divided by 12 months each year equals 0.166667 years.

How to resolve our equation

A = 2000(1 + (0.023 × 0.166667)) = 2007.666682

A = $2,007.67

Simple interest on a principal of $2,000.00 at a rate of 2.3% annually for 0.166667 years (2 months)

If Latanya receives 60 rewards points just for signing up. She earns 9.5 points for each visit to the movie theater. She needs 117 points for a free movie ticket. Then 6 visits Latanya has to make to earn a free ticket.

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

Given that,

Latanya has 60 rewards points just for signing up.

For each visit to theatre she earns 9.5 points.

To get free ticket she needs 117 points.

We need to find how many visits she has to do to get free ticket.

We use Linear equation to solve this

Let y = total number of rewards points

x = number of visits to the movie theater

m=Points for each visit

y=mx+b

117=9.5x+60

Subtract 60 on both sides

117-60=9.5x

Side Opposite of ∠F = MD

Side Adjacent of ∠F = MF

Side Opposite of ∠D = MF

Side Adjacent of ∠D = MD

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

The triangle FMD and the ∠M is a right angle

So , ∠M = 90°

From the figure , we can deduce that

The Hypotenuse = FD

Side Opposite of ∠F = MD

The equation which relates the number of triangles in figure (n) to the perimeter of the figure (P) is P = 6n + 18. Option A is correct.

We are given:

The perimeter of the 1 triangle = 24

The perimeter of the 2 triangle = 30

The perimeter of the 3 triangle = 36

As we can see in the given figures two sides with lengths of 9 are fixed and the side with a length of 6 is varying.

So, we can write this as,

P = 6n + 18, where n = number of triangles.

Now, check the equation formed by substituting the values;

Substitute n = 1, and we get;

P = 6(1) + 18

P = 6 +18

P = 24 True.

Substitute n = 2, and we get;

P = 6(2) + 18

P = 12 +18

P = 30 True.

Substitute n = 3, and we get;

P = 6(3) + 18

P = 18 + 18

P = 36, true.

The probability to take 5 classes is 0.1, while the probability to take at least one class is 0.6, the probability to take 2 or 3 classes is 0.23 and the expectation of the distribution is 1.37.

The distribution given is

X                  PIX)

0                  0.4

1                   0.25

2                  0.15

3                  0.08

4                  0.02

5                  ???  

1.

We know that the sum of all the probabilities in a probability distribution is always equal to 1.

Let the probability of X = 5 be p

Hence,

0.4 + 0.25 + 0.15 + 0.08 + 0.02 + p = 1

or, 0.9 + p = 1

or, p = 1 - 0.9

or, p = 0.1

Hence the probability to take 5 classes is 0.1.

2.

We need to find P(X ≥ 1)

= 1 - P(X = 0)

From the distribution we know that P(X = 0) is 0.4

Therefore, P(X ≥ 1)

= 1 - 0.4

= 0.6

Hence, the probability to take at least one class is 0.6

3.

The probability to take 2 or 3 classes in a semester

= P( X = 2)  +  P(X = 3)

= 0.15  +  0.08

= 0.23

4.

The expectation of any distribution

= ∑xp(x)

where,

x is the random variable

p(x) is the probability of the random variable

Therefore,

E(X) = 0 X 0.4  +  1 X 0.25  +  2 X 0.15  +  3 X 0.08  +  4 X 0.02  +  5 X 0.1

= 0  +  0.25  +  0.30+  0.24  +  0.08  +  0.50

What is the standard deviation?

A standard deviation is a measurement of the data's dispersion from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

Standard deviation  It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.

For example: To find the standard deviation, you have to add up all the numbers in the data set, then divide by how many numbers there are, and that will get you your answer.

Formula:

t=(mean-time)/(standard deviation/√(number of students) )

=( 12 - 11.8) / (1.9 / √13 )
