A set of data already has the values 11, 14, 23, and 16. What value would have to be added to the set for the mean of the
five numbers to be 18?
08
12
18
26

Answer:

The answer is 4

Step-by-step explanation:

The angles in a triangle add up to 180 degrees.

You have two angles given 90(right angle) and 57.

Add them to get 147 then subtract from 180.

180 - 147 = 33

Set 33 equal to the expression

33 = 4x + 17

33- 17 = 4x

16 = 4x

4 = x

Answer:

(0,2) is the answer - Option C.

Step-by-step explanation:

Equation of a line:

The equation of a line, in point-slope form, is given by:

[tex]y - y_0 = m(x - x_0)[/tex]

In which m is the slope and the point is [tex](x_0,y_0)[/tex]

Slope of 9/5 if one of the points on the line is (-10, -16)

This means that [tex]m = \frac{9}{5}, (x_0,y_0) = (-10,-16)[/tex]. So

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - (-16) = \frac{9}{5}(x - (-10))[/tex]

[tex]y + 16 = \frac{9}{5}(x + 10)[/tex]

Which of the following could be another point on the line?​

We have to find a point for values of x and y which gives us an identity. So

Option A:

x = -5, y = -6

Lets see

[tex]-6 + 16 = \frac{9}{5}(-5+10)[/tex]

[tex]10 = \frac{9*5}{5}[/tex]

[tex]10 = 9[/tex] -> False

So this is not the answer.

Option B:

x = 4, y = 11

[tex]11 + 16 = \frac{9}{5}(4 + 10)[/tex]

[tex]27 = 9*14/5[/tex]

False

Option C:

x = 0, y = 2

[tex]2 + 16 = \frac{9}{5}(x+10)[/tex]

[tex]\frac{90}{5} = 18[/tex]

[tex]18 = 18[/tex]

True, so (0,2) is the answer - Option C.

Answer:

53.1

Step-by-step explanation:

They're equal, so 8 = 31 and 13.7 = x

8/31 = 13.7/x

31(13.7) / 8 = 53.0875

Round your answer to nearest tenth to get 53.1

The rounded length of DE is 53.1.

What is similar triangles?

Similar triangles are triangles that have the same shape, but their sizes may vary.

The both the triangles are similar, so the side length CB will be equal to FE and the side length AB will be equal to DE. Hence, the equation formed will be,

[tex]\frac{8}{31}=\frac{13.7}{DE}[/tex]

On solving this equation, we have DE=53.0875.

Therefore, the rounded length of DE is 53.1.

Answer:

1 1/2 teaspoons!

Step-by-step explanation:

Answer:

1 1/2 teaspoons

Step-by-step explanation:

3/4 is to 1 1/8 as 1 is to x

converting 1 1/8 to an improper fraction gives:  

3/4 is to 9/8 as 1 is to x

  (3/4)/(9/8) = 1/x

cross multiply

(3/4)x = 9/8

multiply both sides by 4/3

x = (9/8)(4/3)

x = = 3/2 = 1 1/2

For example,

Given: an=2an−1−xan=2an−1−x

a5=99a5=99

a3=27a3=27

a5=2a4−x=2(2a3−x)−x=4a3−3x=99a5=2a4−x=2(2a3−x)−x=4a3−3x=99

Answer:

x = 18

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 5x + 72 = 180

6x + 72 = 180

6x = 180 - 72

6x = 108

x = 18

Answer:

21.6

Step-by-step explanation:

5x+72=180 (set it to 180 because the total angle sum of a triangle is 180)

5x=108

x=21.6

Answer:

33 students

If you divided the class into groups with 4 boys and 7 girls in each group, there will be 11 students in each group.

The total number of students in the class therefore must be a multiple of 11.

The only multiple of 11 between 24 and 40 is 33.

There are therefore 33 students.

4/11×33=12 are boys and 7/11×33=21are girls.

12:21= 4:7

Answer:

  1)  f⁻¹(x) = 6 ± 2√(x -1)

  3)  y = (x +4)² -2

  5)  y = (x -4)³ -4

Step-by-step explanation:

In general, swap x and y, then solve for y. Quadratics, as in the first problem, do not have an inverse function: the inverse relation is double-valued, unless the domain is restricted. Here, we're just going to consider these to be "solve for ..." problems, without too much concern for domain or range.

__

1) x = f(y)

  x = (1/4)(y -6)² +1

  4(x -1) = (y-6)² . . . . . . subtract 1, multiply by 4

  ±2√(x -1) = y -6 . . . . square root

  y = 6 ± 2√(x -1) . . . . inverse relation

  f⁻¹(x) = 6 ± 2√(x -1) . . . . in functional form

__

3) x = √(y +2) -4

  x +4 = √(y +2) . . . . add 4

  (x +4)² = y +2 . . . . square both sides

  y = (x +4)² -2 . . . . . subtract 2

__

5) x = ∛(y +4) +4

  x -4 = ∛(y +4) . . . . . subtract 4

  (x -4)³ = y +4 . . . . . cube both sides

  y = (x -4)³ -4 . . . . . . subtract 4

Answer:

-2

Step-by-step explanation:

I'm not 100% sure but...

The x-intercept is when the y is 0.

And if we look at the coordinate plane, then we see that the x-intercept is two units down, and y is zero, which means that it would probably mean that the x-intercept is -2.

Answer:

19

Step-by-step explanation:

given that 8 + m = 27

we need to find m

we can do this by isolating the variable using inverse operations

8 + m = 27

we want to get rid of the 8 in 8 + m

The opposite of addition is subtraction

So we want to subtract by 8 but remember what ever we do to one side we want to do to the other side

So we subtract 8 from each side

8 - 8 cancels out

27 - 8 = 19

we're left with m = 19
