Answer:

2

Step-by-step explanation:

Completing the Square:

x^2 - 2x = 54

x^2 - 2x + 1 = 54 + 1

(x-1)^2 = 55

x - 1 = ±[tex]\sqrt{55\\}[/tex]

x = 1 ± [tex]\sqrt{55}[/tex]

Answer:

c. -18.5x ≤ 407

Step-by-step explanation:

-18.5 x -22 = 407

-18.5 x 0 = 0

-18.5 x 6 = -111

-18.5 x 17 = -314.5

-18.5 x 60 = -1110

(All products are either less than or equal to 407)

190 + 130 = 320

Answer:

The area is 6[tex]\sqrt{45}[/tex]

Step-by-step explanation:

Using the Pythagorean Theorem, you'll get that half the base is [tex]\sqrt{45}[/tex], so the entire base is [tex]2\sqrt{45}[/tex]. Multiply that by the height and divide by two, you'll get that the area of this triangle is 6

Answer:

Equal to the difference between median and 75th percentile.

Step-by-step explanation:

xth percentile:

If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.

Distance between percentiles:

If the difference between two percentiles is the same, the difference between the measures should also be the same.

Median:

The 50th percentile is called median.

In this question:

75th percentile - 50th percentile = 25

50th percentile - 25th percentile = 25

The differences should be equal.

Answer:

52%

Step-by-step explanation:

13×4= 52%

You just multiply by 4 to get the percentage

Answer:

1 and ahalf, so 1 1/2

Step-by-step explanation:

The cost per hour for the labor will be $75

Total amount charged = $530.50

Amount charged for parts = $193

Number of hours used = 4.5 hours

Let the amount charged per hour = x

Therefore, the equation to solve the question will be:

193 + 4.5(x) = 530.50

193 + 4.5x = 530.30

Collect like terms

4.5x = 530.50 - 193

4.5x = 337.50

Divide both side by 4.5

4.5x/4.5 = 337.50/4.5

x = 75.

The cost of labor per hour is $75

Answer: a. It is commonly referred to as the arithmetic average.

b. It is algebraically defined (that is, there is an equation you can use to calculate its value).

c. It is easily influenced by extreme scores.

Step-by-step explanation:

The mean is also referred to as the "average" and it is gotten by adding every number and the dividing the value gotten by the number of the numbers used for the calculation.

It should be noted that the mean is algebraically defined and can be easily influenced by extreme scores.

Answer:

5

Step-by-step explanation:

First, you would add 10 to both sides to get 45 = 9n. Then, you would divide both sides by 9 to get n = 5. I hope this helps :)

Answer:

n = 5

Step-by-step explanation:

35 = 9n - 10

First, add 10 to each side.

35 + 10 = 9n - 10 + 10

45 = 9n

Divide both sides by 9

9n/9 = 45/9

n = 5

Answer:

136

Step-by-step explanation:

Let the three consecutive numbers be a, a + 1, a + 2

Therefore,

a + a + 1 + a + 2 = 405

3a + 3 = 405

3a = 405 - 3

3a = 402

a = 402/3

a = 134

Third number = a + 2 = 134 + 2 = 136

Answer:

The answer is 0

Step-by-step explanation:

input into slope formula

The slope of the line is 0.

The correct option is (B).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Points from the graph (1, 2) and (5, 2).

So, the slope of line

= ( 2- 2) / (5 -1)

= 0 / 4

= 0

Hence, the slope of line is 0.

Answer:

m∡1 = 95°

m∡2 = 85°

m∡3 = 95°

Step-by-step explanation:

m∡1 + 85 = 180;   m∡1 = 95°

m∡2 = 85° because it is vertical and congruent to the angle measured 85°

m∡3 = m∡1 = 95° because they are vertical and congruent

Answer:

1 = 95, 2 = 85, 3 = 95

Step-by-step explanation:

2 is an opposite angle of 85 degrees so 2 is 85 degrees

a line is always 180 degrees:

1 = 180 - 85 = 95 degrees

1 is an opposite angle of 3 so 3 is also 95 degrees
