The box plot that matches the data is a box and whisker plot is shown above a number line that extends from 0 to 20 with 1-unit markings. The box extends from 4 to 8, with the median at 5. There is also a point marked at 7. The whisker on the left extends from 2 to 4. The whisker on the right extends from 8 to 12.

A box and whisker plot is a graph that is made up of two lines and a box. The two lines are known as whiskers. The end of the first whisker is the minimum value and the end of the second whisker is the maximum value.

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

Angles 1 and 2 are remote interior angles while angle 3 exists as a remote exterior angle. The required relationship between the angles 1, 2, and 3 is ∠1 +∠2 = ∠3.

The triangle exists a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.

Angles 1 and 2 are remote interior angles while angle 3 exists as a remote exterior angle. So there exists a property of a triangle in that the sum of the remote interior angles exists equivalent to the remote exterior angle.

∠1 +∠2 = ∠3.

Therefore, the required relationship between the angles 1, 2, and 3 is ∠1 +∠2 = ∠3.

The next place value on the right should be used to round a number to the closest tenth (the hundredths). Simply take away all the digits to the right if it's 4 or fewer. Remove all the digits to the right after adding 1 to the digit in the tenths position if the number is five or above.

To what decimal place do you round?

Examine the hundredth number to determine the decimal number's nearest tenth. Add one to the tenth value if the number is more than 5. Remove all the numbers that are present after the tenth place if the value is less than 5, but keep the tenth place value in place otherwise. As an illustration, if you want to round up to the nearest.

Subtract 4 from each side

9-4 ≤ 3x +4-4

5 ≤ 3x

Divide each side by 3

5/3 ≤ 3x/3

5/3 ≤ x

x must be greater than or equal to 5/3

As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile

We can calculate the total distance traveled by a body with position function s (t) if it moves along a coordinate line without changing direction from t = a to t = b. If the body changes direction during the journey, we must integrate the body's speed |v (t)| to find the total distance traveled.

Therefore,

We know Mary spent only a third of the time coming from school as she did going because she traveled three times as fast coming from school as she did going to school (6 miles per hour versus 2 miles per hour). If x represents the time it took her to get to school, then x/3 represents the time it took her to return.

Knowing that the total trip took 1 hour, we have:

x + x/3 = 1

3x/3 + 1x/3 = 1

4x/3 = 1

x  = 3/4

So we know it took Mary 3/4 of an hour to get to school (and 1/4 of an hour to get home).

Remembering that distance = rate × time, Mary's commute to school was (2 miles per hour) × (3/4 of an hour) = 3/2 mile. Furthermore, because she returned via the same route, she must have traveled 3/2 of a mile.

As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile.

The prices for jeans and shirts are $6 and $6

Given that:

And 2 pairs of jeans and 3 shirts for $30.

Let jeans be x

Let shirts be y

3x + 7y = 60.... eq 1

2x + 3y = 30...... eq 2

Let us make x the subject formula from equation 2

2x = 30-3y

x= (30-3y)/2..... eq 3

Put the value of x into equation 1

3 * (30-3y)/2 + 7y = 60

(90- 9y)/2 + 7y = 60

45 - 4.5y + 7y = 60

2.5y =15

y = 6

Then, put the value of y into eq 3

The equation that represent the relationship model that will reach $0 in the same number of days as the scenario gave is: y = -2x + 12

To solve this problem, we have to state the equation using the information of the problem.

Information about the problem:

Writing the equation according to the information gave, we have:

y = -2x + 12

Where:

So that (y) equals zero, the number of days (x) should be = 6

y = -2x + 12

0 = -2*6 + 12

0 = -12 + 12

0 = 0

The "y" variable is the dependent variable, because it will change according to the number of days passed (x).

The "x" variable is the independent variable, because it doesn't depend on any other value, just the number of days passed.

An equation is the equality between two algebraic expressions, which have at least one unknown or variable.

The length of the ladder = 3.8 meter

The length of wall = 2.1 meter

Draw the figure using the measurements

We have to use the trigonometric function

The angle that a ladder make with the ground

sin θ = Opposite side / Hypotenuse

sin θ = 2.1/3.8

θ = 33.54 degrees

The distance from the foot of the ladder from the wall

cos θ = Adjacent side / Hypotenuse

cos 33.54 = Adjacent side / 3.8

Adjacent side = 3.8 × cos 33.54

Step-by-step explanation:

Exact number of steps taken by Anne to cross the road either by striding 80cm or by striding 70cm , then the least width of the road is equal to 5.6meters.

As given in the question,

Anne takes exact number of steps to cross the road either by striding 80cm or by striding 70cm.

Conversion of the units

1 meter = 100 centimeters

1 centimeter = 1/100 meter

80 cm = 80 /100

          = 0.8 meters

70 cm = 70 /100

          =0.7 meters

Least width of the road is calculated by finding least common multiple of 0.8 meters and 0.7 meters

0.8 = 8 × (1/10)

0.7 = 7 × (1/10)

least common multiple = 7 × 8 × (1/10)

                                    = 5.6 meters

Therefore, exact number of steps taken by Anne to cross the road either by striding 80cm or by striding 70cm , then the least width of the road is equal to 5.6meters.

The cost of the jam Elmo uses to make the sandwiches =$1.65

What is the cost of the jam Elmo uses to make the sandwiches?

B globs of Peanut butter at 4 cents = 4B

J blobs of Jam at 5 cents = 5J

The number of sandwiches is given by the linear equation,

N(4B + 5J ) =$ 2.53

N(4B + 5J ) = 253 cents    ---(1)

The factors of 253 = 1, 11, 23, 253.

Since N > 1 , N is 11 or 23

Considering N = 11

11(4B + 5J ) = 253

4B + 5J  = 23   ---(2)

The possible values of B and J to satisfy the linear equation:

B = 2 and J = 3

Substituting B and J in (2)

4B + 5J  = 23

4 (2) + 5(3) = 23

8 + 15 = 23

23 = 23

The linear equation is verified.

The cost of jam Elmo uses to make the sandwiches =N( 5J)

                                                                                       =11 (5*3)

Answer:

In the graph, the coordinate point (4,-9) is a vertex

In the graph, the coordinate point (1,0) is an x-intercept

In the graph, the coordinate point (7,0) is an x-intercept

In the graph, the coordinate point (4,0) is on the line of symmetry.

Explanation:

The x-intercepts are the points where the parabola crosses the x-axis, so the coordinates of the x-intercepts are (1, 0) and (7, 0)

The y-intercept is the point where the parabola crosses the y-axis, so the y-intercept is (0, 7)

The vertex is the minimum point of the parabola, in this case, (4, -9).

The line of symmetry depends on the first coordinate of the vertex, so the line of symmetry is x = 4. It means that any point with a first coordinate equal to 4 is on the line of symmetry.

Then, the answers are:

In the graph, the coordinate point (4,-9) is a vertex

In the graph, the coordinate point (1,0) is an x-intercept

In the graph, the coordinate point (7,0) is an x-intercept

in the graph, the coordinate point (4,0) is on the line of symmetry.

The probability that the score of a randomly selected examinee is less than 370 is 0.113

Mean of the gmat score = 410

Standard deviation of the deviation = 33

The randomly selected examinee be X ,

Thus X = 370

So , we need to find the probability that the score of a randomly selected examinee is less than 370 i.e.

   P(X < 370)

Now , let us the z-score with normal distribution formula

        Z = (X - μ) / σ

        Z = (370 - 410) / 33

        Z = -40 / 33

       Z = -1.21

Thus P(X < 370) = P(Z < -1.21)

From the z - table , we can get that

         P(Z < -1.21) = 0.11314

By rounding off to three decimals ,
