The slope of the line is 1. Two different points have the same slope.

Rise or fall is a number or ratio that determines the direction or slope of the line. The slope of a straight line is the ratio of the slope of the straight line to the course of the straight line. The point is:

-XY

twenty-five

−2 1

0 3

-7 -4

The slope of a straight line is generally calculated using the formula:

slope = [tex](y_{2} - y_{1} ) / (x_{2} - x_{1} )[/tex]

Points (2, 5) and (-2, 1) of part (A).

Slope = [tex]( 1 - 5 ) / ( -2 - 2 )[/tex]

Slope = -4 / -4 = 1

Split (B) at the points ( 0, 3 ) and ( -7, - 4 ).

Slope = [tex]( -4 - 3 ) / ( -7 - 0 )[/tex]

Slope = -7 / -7 = 1

The slope of the line at two different points is the same.

The system of equations that represents the number of each type of basket Jake scored is  given by:

x  + y = 13

2x +  3y = 28

A system of equations is   when two or more variables are related, and equations are built to find   the values of each variable.

In this problem,   the variables are:

Variable x: Number of  2-point shots.

Variable y: Number of 3-point shots.

Jake scored 28 points in his   basketball game   by shooting only 2-point and 3-point   shots, hence:

2x  +  3y = 28.

He scored a total   of 13 baskets, hence:

x  + y  = 13.

The probability is 0.05.

When using two water heaters as the inspection unit, the center line and control limits consistent with the past 22 days of inspection data are calculated as follows:

Center line (CL) = (X1 + X2)/2

Upper control limit (UCL) = CL + 3 * s/2

Lower control limit (LCL) = CL - 3 * s/2

Where X1 and X2 are the means of the two water heaters, and

s is the standard deviation of the sample data.

The probability of type I error for the control chart in part (b) is typically set at 0.05,

meaning that there is a 5% chance of rejecting the null hypothesis when it is actually true.

Answer:

Stephanie Mary and Nicole

Step-by-step explanation:

Answer: 42

Step-by-step explanation:

We start by looking at the 49 degree angle. A common method of solving geometric problems is to bring things together. To follow this concept, we can say that the 49 degree angle has a vertical angle inside the triangle, which means that angle is 49 degrees. We now work with the 91 degree angle. We can see the 91 degree angle falls on a line, so the other side of the angle equals 180-91=89. All angles in a triangle add up to 180 degrees, so x + 49 + 89 = 180, so x=180 - 138 = 42.

A basketball court takes the shape of a rectangle and the perimeter of a rectangle is =88m

The area encircling a two-dimensional figure is known as its perimeter. Whether it is a triangle, square, rectangle, or circle, it specifies the length of the shape. The two primary characteristics of a 2D shape are area and perimeter.

Each form has a different perimeter depending on its measurements. The perimeter is only ever stated as the circle's diameter when referring to a circle. So we must add all of the sides of each polygon to determine its perimeter, which is the same for all polygons.

A basketball court takes the shape of a rectangle and the perimeter of a rectangle is calculated by the formula:

= Length + Length + Width + Width

Slotting the figures in will give:

= 27 + 27 + 17 + 17

it takes 6 hοurs fοr the sleighs tο be 390 miles apart.

velοcity is a unit οf measurement fοr the Distance an οbject travels in a

the predetermined periοd οf time. Here is a wοrd equatiοn that illustrates the cοnnectiοn between space, speed, and time: velοcity is calculated by

dividing the tοtal Distance traveled by the jοurney time.

Since the sleighs are traveling in οppοsite directiοns, their distances frοm each οther are increasing at a cοmbined rate οf 20 mph + 45 mph = 65 mph. We can use the fοrmula:

distance = rate x time

Let's call the time it takes fοr the sleighs tο be 390 miles apart "t". Then we can write:

390 = 65t

Sοlving fοr "t", we can divide bοth sides by 65:

t = 6

Answer:

Below

Step-by-step explanation:

Area of a triangle = 1/2  base * height

  this triangle has base = 4 ( 3 in) = 12 in    and height = 3 (3 in) = 9 in

 area = 1/2 * 12 * 9 = 54 in^2

54 in^2 *  $ 2.75 /in^2 = $ 148.50

If the window is scaled down by .5 then the dimensions would be

  base = 6 in   height = 4.5 in

    area = 1/2 * 6 * 4.5 = 13.5 in^2

      cost would be    13.5 in^2   *  $ 2.75/in^2  =~ $37.13

Step-by-step explanation:

In the triangle , the cοrrect οptiοn is  B) b = CD sin(A) and a = CD sin(B).

A triangle is a fοrm οf pοlygοn with three sides; the intersectiοn οf the twο lοngest sides is knοwn as the triangle's vertex. There is an angle created between twο sides. One οf the crucial elements οf geοmetry is this.

Certain fundamental ideas, including the Pythagοrean theοrem and trigοnοmetry, rely οn the characteristics οf triangles. The angles and sides οf a triangle determine its kind.

Here the given triangle CD is altitude.

According to the given statement table , in 4th statement we have definition of sine , Then

=> Sin(A) = [tex]\frac{CD}{b}[/tex] and Sin(B) = [tex]\frac{CD}{a}[/tex]

Option B, 18 million, is the answer to this question.

In September 1998, the population of West Goma in millions was modeled by the function f(x) = 17.9e0.002x, and the population of East Goma in millions was modeled by the function g(x) = 13.6e0.017x. Here, x represents the year, with x=0 corresponding to September 1998.

To find out the point of intersection where the populations are equal, we equate both formulas and solve for x:

17.9e0.002x = 13.6e0.017x

Taking the natural logarithm of both sides of the equation gives:

x ln(17.9) + 0.002x = x ln(13.6) + 0.017x

Simplifying and rearranging terms, we get:

ln(17.9) - ln(13.6) = (0.017 - 0.002)x

0.079 = 0.015x

Solving for x, we get:

x = 5.27 years

Since x is the year, when x = 5.27, it corresponds to the year 1998 + 5.27 ≈ 2003.

When the populations are equal, the population will be f(5.27) ≈ 18 million for West Goma.
