Answer:

25 feet long and 16 feet wide

Step-by-step explanation:

16 x 2 = 32
32 - 7 = 25
25 x 16 = 400

If PQ=3x+8 and QR=2x + 17, the value of x is 31.

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. The linear pair postulate or linear pair theorem in mathematics states the same thing mathematically. The sum of the measurements of two angles that make up a linear pair is 180°.

Given

Value of lines,

PQ = 3x + 8

QR = 2x + 17

Linear pair theorem,

3x + 2x + 8 + 17 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 155/5

Value

x = 31

The linear model equation for the given data is y = 2x  .

In the question ,

it is given that ,

a data table is given ,

from the table we can see that ,

when x is = 2 , the value of y = 4 ,

and when x is = 4 , the value of y = 8 .

So , we have two points as (2,4) and (4,8) .

the slope of the line is = (8-4)/(4-2)

= 4/2

= 2 .

So , the equation of the line with m = 2 and (x,y) = ( 2,4) will be

(y - 4) = 2(x - 2)

y - 4 = 2x - 4

Adding 4 in both sides of equation ,

we get ,

y = 2x

1 triangle is half of a square

36 divided by 4 is 9

The figure was rotated 270° counterclockwise and was translated 2 units to the left.

Translation moves a shape left, right, up, or down but does not turn. The translated shapes (or the image) appear to be the same size as the original shape, indicating that they are congruent.

if we pick a point on the shape with a coordinate (3,2) if we rotate that point 270° counterclockwise the new coordinates become ( 2, -3)

From the graph the final coordinates of that point i (0, -3)

Which means that point moved from point 2 to point 0 2 units to the left.

So then shape was translated 2 units to the left.

In conclusion, the shape was translated by 2 units to the left.

A set of statistics exam scores are normally distributed with a mean of 76. 5576. 5576, point, 55 points and a standard deviation of 555 points. 28.34% proportion of exam scores are between 797979 and 86. 586. 0586..

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean.

Given,

Mean = 76.55

Standard deviation = 5

To calculate this, we first need to get the Z score mathematically

Z = X - mean/standard deviation

For the 79,

Z = 79 - 76.55/5

Z = 0.49

For the 86.05

Z = X - mean/standard deviation

Z = 86.05 - 76.55/5

Z = 1.9

So, we have

P(0.49 < Z < 1.9)

P( Z < 1.9) - P( Z < 0.49)

Using the table of standard score probability

P(Z < 1.9) = 0.9713

P( Z < 0.49) = 0.6879

P( Z < 1.9) - P( Z < 0.49)

0.9713 - 0.6879

0.2834

We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format.

Slope is a measure of how much a line changes in the y-direction for every unit of change in the x-direction. It is typically represented by the m in the equation y = mx + b. The slope of (-1,2) is undefined because it has only one point.

Slope is calculated by taking the difference in the y-coordinates divided by the difference in the x-coordinates of two points on a line. Since we only have one point, we cannot calculate the slope.Slope is a measure of how steep a line is, and is calculated by taking the ratio of the change in the y-coordinate to the change in the x-coordinate. Since we only have one point, we don't have any changes and therefore cannot calculate the slope.

The measure of angle B is given as follows:

m < B = 19.12º.

The measure of angle B is obtained applying the law of sines, which states that the ratio between the sine of an angle and the length of the opposite side to the angle is equals for all three angles.

The angles for the triangles are given as follows:

Then the measure of angle C is calculated as follows:

sin(148º)/1950 = sin(C)/820

sin(C) = 820 x sin(148º)/1950

sin(C) = 0.22283784444

C = arcsin(0.22283784444)

C = 12.88º.

The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of angle B is obtained as follows:

148 + 12.88 + x = 180

x = 180 - (148 + 12.88)

A basic version says that if (N+1) pigeons occupy N holes, then some hole must have at least 2 pigeons. Thus if 5 pigeons occupy 4 holes, then there must be some hole with at least 2 pigeons.

We know that there are 40 odd integers 1, 3, 5, 7, ....79 and 41 even integers 0, 2, 4, 6, .....80 from 0 to 80 .

So, at most, 41 integers picked out of them. If we pick one more integer after picking all of these then it must be odd integer according to Pigeonhole  Principle. Therefore, we need to at least one more integer from 0 through 80 to be sure that there is at least one odd integer.

Answer: Red.

Step-by-step explanation:

There are 10 marbles of each colour as described here: 'A bag contains the same number of each of four different colors of marbles.' The theoretical probability of drawing any marble of a select colour is 1/4. The red marble was drawn 10 times, making it fit this 1/4 theoretical probability.

Answer:

Let us label the point where the two circles touch as point B. Since the two circles have the same size and are tangent to each other at point B, the radii of both circles must be equal. Let the radius of the circle be r.

Since triangle ACE is equilateral, all sides of the triangle must be equal in length. Since the circumference of each circle is 66 cm, the length of each side of triangle ACE must be 66/3 = 22 cm.

Since the radius of the circle is tangent to the side of the triangle at point B, the length of line segment EB must be equal to the radius of the circle. Since the length of line segment EB is 29.7 cm, the radius of the circle must be 29.7 cm.

The area of the shaded region can be found by subtracting the area of the smaller circle from the area of the larger circle. The area of a circle with radius r is given by the formula A = πr², where A is the area of the circle and r is the radius of the circle. Since the radius of the smaller circle is 29.7 cm, the area of the smaller circle is 29.7²π = 869.43π cm².

Since the radius of the larger circle is half the length of the side of the triangle, the radius of the larger circle must be 22/2 = 11 cm. The area of the larger circle is therefore 11²π = 121π cm².

The area of the shaded region is therefore 121π - 869.43π = -748.43π cm². Since the area of a region cannot be negative, the answer to the question must be 0 cm². The area of the shaded region is therefore 0 cm².
