Answer:

5.   y = -x

Step-by-step explanation:

First, you need to find the slope of the line.

[tex]m = \frac{2 - (-3)}{-2 - 3} = \frac{5}{-5} = -1[/tex]

Now, using either point substitute into the point-slope form for a line:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

Using (-2,2) for [tex](x_{1} , y_{1} )[/tex] we get y - 2 = -1(x +2)

y - 2 = -x - 2

y = -x

Answer 5 is the correct answer

Answer:

Interquartile Range

The interquartile range of an observation variable is the difference of its upper and lower quartiles. It is a measure of how far apart the middle portion of data spreads in value.

Interquartile Range = U pper Quartile − Lower Quartile

Problem

Find the interquartile range of eruption duration in the data set faithful.

Solution

We apply the IQR function to compute the interquartile range of eruptions.

> duration = faithful$eruptions     # the eruption durations

> IQR(duration)                     # apply the IQR function

[1] 2.2915

Answer

The interquartile range of eruption duration is 2.2915 minutes.

Answer:

10

Step-by-step explanation:

As I understand it, we are asking for 3/5 = 6/x, what is x?

You cross-multiplythe numerators and denominators.

3x = 30

x = 10

And 3 is to 5 as 6 is to 10.

In each case, the fraction = 0.6

The fourth proportion of 3: 5:: 6:__ is 10.

In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.

Given, the proportional of 3: 5:: 6: ___  To find the fourth proportional

Let x be the fourth proportional.

Thus,

[tex]\frac{3}{5} = \frac{6}{x}[/tex]

x = (5*6)/3

x = 5*2 = 10

therefore, The fourth proportion of the given data is 10

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (3, - 3)

m = [tex]\frac{-3-(-5)}{3-(-1)}[/tex] = [tex]\frac{-3+5}{3+1}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

since m is parallel to n, this means that the two angles are alternate angles. Hence, 46°=6x-2

Calculate and you should get x = 8°

Answer:

P = 10w

Step-by-step explanation:

Number of point per correct spelling = 10

Number of words spelt correctly = w

Total points, p

P = (number of points per correct spelling * number of words spelt correctly)

P = 10 * w

P = 10w

Answer:

x = 2 and y = 7

Step-by-step explanation:

We are given two equations:

1.      8x + y = 23

2. −10x  - y = −27

By adding both equations with each other we get:

(1.+2.) -2x = -4

Which can be reduced to:

(1.+2. : (-2)) x = 2

We can insert x in Equation 1. (or 2) and get:

8*2 + y = 23

16 + y = 23         [-16 on both sides]

y = 7

Resulting in x = 2 and y = 7 as a possible solution for this system.

Answer:

Step-by-step explanation:

8x + y = 23

-10x - y = -27

-2x = -4

x = 2

8(2) + y = 23

16 + y = 23

y = 7

Step-by-step explanation:

The perimeter is the length of the edge of the overall shape. In this case, the edge includes the length of the curved section of both semicircles (since semicircles are the same size, we can just find the circumference for a circle with the same radius), plus four side lengths of the square.

The radius is 10 (Two squares line up exactly with the semi-circles).

Circumference: 2πr=2π10=20π

Perimeter =20π+4(10)=40+20π

40+20π=40+20π? YES

Hi there!

To find the rate at which Gia can run, you have to divide 4 by 32 to find how many miles she runs per min. When you do that, you get .125 Gia runs .125 miles per min. To find how many miles she runs in 40 min, you multiply .125 by 40 to get 5. This means that Gia runs 5 miles in 40 min.
