Answer:

the third one ithink

Step-by-step explanation:

The sum of angles X and Z is 90°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle XYZ.

∠Y = 90°

Now,

The sum of the three angles must be 180°.

So,

∠X + ∠Y + ∠Z = 180

∠X + ∠Z = 180 - 90

∠X + ∠Z = 90

Thus,

∠X + ∠Z = 90

The length of the other side of the wall is √500 ft

To get the length of 'd', we will use the pythagoras theorem as shown below:

Given the following

According to the theorem;

[tex]h^2=a^2+d^2\\30^2 = 20^2 + d^2\\900 = 400 + d^2\\d^2 = 900 - 400\\d = \sqrt{500} ft[/tex]

Hence the length of the other side of the wall is √500 ft

Answer:

The answer is option A y = −1.988x + 43.293

Step-by-step explanation:

I just took the test

The equation of the least squares regression line for the data set will be;

y = -1.988x + 43.293

Option A is true.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The table of data set is shown in figure.

Now, Let hours represent by x.

And, Tickets sold represent by y.

So, By the equation;

y = -1.988x + 43.293

Substitute x = 11;

y = -1.988 × 11 + 43.293

y = - 21.868 + 43.293

y = 21.62

y = 22

And, For x = 9;

y = -1.988 × 9 + 43.293

y = -17.892 + 43.293

y = 25.4

y = 24

Thus, Equation y = -1.988x + 43.293 shows the least-squares regression line for the data set.

So, The equation of the least squares regression line for the data set will be;

y = -1.988x + 43.293

Answer:

y = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition

y = 6 when x = 18 , then

6 = 18k ( divide both sides by 18 )

k = [tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex]

y = [tex]\frac{1}{3}[/tex] x ← equation of variation

When x = 8, then

y = [tex]\frac{1}{3}[/tex] × 8 = [tex]\frac{8}{3}[/tex]

Answer:

The slope intercept form of (0,3) and (4,2) is y= -1/4x+3

Step-by-step explanation:

The distance from our y values from 3 to 2 is -1.

The distance from our x values is 4.

We can put these values as our slope and we know that the Y values are always rise and the x values are always run

Therefore we get y= -1/4x+3 (side note: The 3 is our y intercept, this means that the x value of the three is always 0. For example, in (0,6) the y intercept would be 6.

Hope this helps! :)

Answer:

7 ≤ v ≤ 13

Step-by-step explanation:

Length of video required must be within 10 minutes

Submitted length of video must be with 3 minutes of the 10 minutes video

To create an absolute value inequality :

Let v = the range of value for which the required video will be :

|v - 10| = ±3

Lower boundary :

|v - 10| = - 3

v = - 3 + 10

v = 7

Upper boundary :

|v - 10| = 3

v = 3 + 10

v = 13

Hence,

7 ≤ v ≤ 13

Answer:

no solution

Step-by-step explanation:

Given

[tex]\frac{1}{3}[/tex] (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution
