Step-by-step explanation:

First, you can plot this using a table. One side can be 'Women' and the other 'Men'. One the vertical side of it, write '1980', '1981', '1982', etc., for maybe fifteen years to be on the safe side. Then, your starting value is 6 million and 5.4 million, respectively.

Finally, start adding up, It will be, 6.14 million, 6.28 million, etc., and 5.4 million, 5.48 million, etc.

Once you're done, you can circle the year both were the same, and you can even plot this on a graph

Answer:

What he said above me and he is correct

Step-by-step explanation:

Let's solve your system by substitution.

2x−2y=−4;2x+y=11

Rewrite equations:

2x+y=11;2x−2y=−4

Step: Solve2x+y=11for y:

2x+y=11

2x+y+−2x=11+−2x(Add -2x to both sides)

y=−2x+11

Step: Substitute−2x+11foryin2x−2y=−4:

2x−2y=−4

2x−2(−2x+11)=−4

6x−22=−4(Simplify both sides of the equation)

6x−22+22=−4+22(Add 22 to both sides)

6x=18

6x/6 = 18/6

(Divide both sides by 6)

x=3

Step: Substitute3forxiny=−2x+11:

y=−2x+11

y=(−2)(3)+11

y=5(Simplify both sides of the equation)

Answer:

Answer:

She drinks 4.8 ounces of water per hour

Step-by-step explanation:

We know

Yasmin drank 3/4 of an 8-ounce glass of water in 1 1/4 hours

3/4 of 8 ounce = 6 ounces

1 1/4 = 5/4 = 1.25 hours

How much can she drink per hour?

6 divided by 1.25 = 4.8 ounces of water per hour

So, she drinks 4.8 ounces of water per hour.

When the patient recovery time from a specific surgical procedure is normally distributed, with a mean of 5.2 days and a standard deviation of 2.3 days, the probability of spending more than 2 days in recovery will be 0.61.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. Information about the likelihood that something will happen is provided by probability. For instance, meteorologists use weather patterns to forecast the likelihood of rain. Probability theory is used in epidemiology to comprehend the connection between exposures and the risk of health effects.

Here,

z=(X-μ)/σ

X=2

μ=5.2

σ=2.3

Z=(2-5.2)/2.3

Z=-1.39

-1.39+1

=0.39

1-0.39=0.61

The probability of spending more than 2 days in recovery will be 0.61 when the patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 2.3 days.

Answer:

students 150

adult 550

Step-by-step explanation:

x + y = 700

5x + 2y = 3050

x = 700 - y

5(700 - y) + 2y = 3050

3500 - 5y + 2y = 3050

-3y + 3500 = 3050

-3y = 3050 - 3500

-3y = -450

y = -450 / -3

y = 150

x = 700 - y

x = 700 - 150

x = 550

The value of b in the matrix with the help of determinant is 8. Thus option B is correct.

According to the statement

we have given that the one matrix and its determinant and we have to find the value of v.

So, For this purpose, we know that the

The determinant in math is a scalar quantity that is a result of the rows and columns of a matrix form.

And according to the given information:

If the determinant of this matrix is 24.

And

The matrix is given below.

\(\left[\begin{array}{ccc}-5&4&1\\5&-7&-4\\-6&b&6\end{array}\right]\)

And put the relation R₁ ⇒ R₁ + R₂ on it then

\(\left[\begin{array}{ccc}0&-3&-3\\5&-7&-4\\-6&b&6\end{array}\right]\)

And put the relation C₂ ⇒ C₂ – C₃ on it then

\(\left[\begin{array}{ccc}0&0&-3\\5&-3&-4\\-6&b-6&6\end{array}\right]\)

Then the value of b will be

–3[5(b – 6) – (–3)(–6)] = 24

            (5b – 30 – 18) = –8

                               5b = 40

                                 b = 8

Then the correct option is B.

So, The value of b in the matrix with the help of determinant is 8. Thus option B is correct.

The width and height of the model are;

Width of model = 13.5 inches

Height of model = 2.25 inches

A scale model is defined as a physical model that is geometrically similar to an object. Scale models are usually smaller than large prototypes such as vehicles, buildings, or people. However, these scale models may be larger than small prototypes such as anatomical structures or subatomic particles.

Now, we are given that the dimensions of the new medical complex are;

Length = 400 ft

Width = 180 ft

Height = 40 ft

Thus, for a scale model with length of 30 in(2.5 ft) long, the scale factor is; Scale factor = 2.5/400

Thus;

Width of model = 180 * (2.5/400)

= 1.125 ft = 13.5 inches

Height = 30 * (2.5/400)

= 0.1875 ft = 2.25 inches

The act of continuing to use the club is contract affirmation or performance. This is because of the agreement with the club to pay a monthly fee for 24 months. When Janice reached the age of majority, she had the option of rejecting the contract, which would mean that she would no longer have to pay the monthly fee.

However, since she continued to use the club six months later after reaching the age of majority, she has effectively affirmed the contract by her actions. Janice's act of continuing to use the club is an example of contract affirmation or performance. Contract affirmation is when one party confirms or accepts the terms of a contract by words, conduct or behavior. It is also known as contract performance.Contract affirmation is common in situations where one party has the option to terminate the contract but continues to perform the obligations under the agreement. In this case, Janice had the option to terminate the contract after reaching the age of majority but chose to continue using the club. This action shows that she has accepted the terms of the contract and is willing to fulfill her obligations under the agreement.In conclusion, Janice's act of continuing to use the club six months after reaching the age of majority is an example of contract affirmation or performance.

Step-by-step explanation:

To determine if the graph is a function, we can use the vertical line test.

Use a vertical line, if the vertical passes through two or more points, the graph is not a function

Looking at the y axis ( which is a vertical line), it passes through two points

This means the graph is not a function

No, the graph fails the vertical line test

The width of the round cake needs to be approximately 2 times the radius, or about 15.6 inches, to have the same volume as the rectangular prism cake.

A three-dimensional structure with six rectangular faces that are parallel and congruent together is called a rectangular prism. It has a length, width, and height. By multiplying the length, width, and height together, one may get the volume. Contrarily, a cylinder is a three-dimensional shape with two congruent and parallel circular bases. It has a height and a radius, and you can determine its volume by dividing the base's surface area by the object's height. A cylinder has curved edges and no corners while a rectangular prism has straight edges and corners.

The volume of the rectangular cake is given as:

V = length * width * height

Substituting the values we have:

16 * 12 * 3 = 576 cubic inches

Now, for the cylindrical cake to be of the same volume we have:

V = π * radius² * height

π * radius² * 3 = 576

(3.14) * radius² * 3 = 576

radius = 15.6 inches

Hence, the width of the round cake needs to be approximately 2 times the radius, or about 15.6 inches, to have the same volume as the rectangular prism cake.

Let:

Replace the value of y into (1):

Angle BCF = 38 degrees

Angle BED = 79 degrees

Angle BDE = 63 degrees

Angle B = 79 degrees

Angle C = 79 degrees

Angle ACF = 38 degrees

Angle F = 104 degrees.

We have,

As ED//BC,

We can say that angle EDB = angle BCF = 38 degrees.

Also, in rhombus ABCF, angles BCF and CAF are equal,

So CAF = 38 degrees.

In triangle BED,

We have angle BED = 79 degrees and angle EDB = 38 degrees.

Angle BDE = 180 - (79 + 38) = 63 degrees.

In triangle BDE,

We also has angle B = angle EBD = 180 - (63 + 38) = 79 degrees.

In trapezium BCDE,

Angles B and C are equal, so angle C = 79 degrees.

Finally, in rhombus ABCF, angles CAF and ACF are equal,

So ACF = 38 degrees.

Therefore,

Angles A and C of triangle ACF equal 38 degrees each, and angle F is:

= 180 - (38 + 38)

= 104 degrees.

Thus,

angle BCF = 38 degrees

angle BED = 79 degrees

angle BDE = 63 degrees

angle B = 79 degrees

angle C = 79 degrees
