The human resources office at your college decided to look at how many years 3 employees had worked at the college. The employees had worked at the college for 4, 9, and 9 years. Find the standard deviation of number of years worked for the employees and round to 1 decimal place if needed.

Answer:

13+34=47

Step-by-step explanation:

Let us call the number x

13+x=47

so we can assume

47-13=x

47=13=34

13+34=47

Answer:

That depend on how much you spend on electricity, and how much other spending you do.

For example: If your electric bill is 100 dollars, and it increases 30 percent to 130, that’s 30 extra dollars. If your electric bill is only 50 dollars, it will increase to 65, that’s an extra 15.

What percentage that increase is of your current spending will vary according to how much you spend. If you only spend 30 dollars, then you’ll need to cut all of it, or half of it to offset the increases I mentioned above. That’s a 100 percent or 50 percent reduction.

If you spend 1000 dollars, you’ll only need to cut spending by 3 percent to get that 30 dollars, or 1.5 percent to get the 15 dollars.

It all depends on your specific values, you can’t say “For every xx percent your electric bill increases, you need to cut spending by yy percent.”

for the consumption of X unit let u spends Y

for X - Y cost

for increased 30% means 13X/10 - 13Y/10 cost

extra money is 13Y/10 - Y = 3Y/10

note: hope this helps :)

thus (3Y/10)/ (13Y/10) *100 % = 300 / 13 = 23.07%.

Answer:

[tex]y=-10x+43[/tex]

Step-by-step explanation:

We need to put this line into slope-intercept form, which is [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the [tex]y[/tex]-intercept.

The slope is rise over run, how much the [tex]y[/tex] value changes for one [tex]x[/tex] value. This can be found with the equation: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points on the line. Plugging in the first two points:

[tex]m=\frac{3-13}{4-3}=-10/1=-10[/tex]

We know them that [tex]m=-10[/tex]. This gives us for now [tex]y=-10x+b[/tex].

Now, to solve for [tex]b[/tex], plug in any one of the points (I'll use (3,13)):

[tex]13=-10(3)+b[/tex]

[tex]13=-30+b[/tex]

[tex]b=43[/tex]

This gives us the equation [tex]y=-10x+43[/tex].

Answer:

[tex]-16500[/tex]

Step-by-step explanation:

In order to find the answer to this question you need to use KCC (Keep, Change, Change) and solve.

[tex]-26000-(-9500)[/tex]

Use KCC

[tex]-26000 + 9500[/tex]

[tex]-26000+9500=-16500[/tex]

[tex]=-16500[/tex]

Answer:

( -3, 11)

Step-by-step explanation:

find the equation of the line between points ( -8, 11) and (-3, 11)

y= mx +b , where m is slope snd b is y-intercept

m = (y2-y1)/ (x2-x1) = 11-11/ -8- -3 = 0/ -5 = 0 ( if slope is o is a horizontal line)

y = 0x + b and pick a point to find b

11 = 0*-8 + b so b= 11

y = 11 is the equation of the line between points ( -8, 11) and (-3, 11) and the equation of its perpendicular line is x=-3

the equation of the line between points  (-3, 11) and ( -3, -12) is x= -3 and the perpendicular to it is y= 11

so we have a right triangle so the ortho center is at (-3, 11) where the vertex of the 90 degree angle is

Answer:

41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.

First we have to calculate the perimeter of 1st triangle.

Given:

a = 33 yards

b = 56 yards

c = 65 yards

Now we have to calculate the perimeter of 2nd triangle.

Given:

a = 26 yards

b = 49  yards

c = 38 yards

Now we have to calculate which triangle has greater perimeter and how much greater.

Therefore, 41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.

Step-by-step explanation:

(154-113)

41 yards bigger

Answer:

41 yds

Step-by-step explanation:

33+56+65=154

26+49+38=113

Answer:

Yes, AAS

Step-by-step explanation:

Yes, both the triangles are congruent by AAS postulate.

Answer:

The  constant of proportionality k = 12

Hence, option A is true.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get

y ∝ x

y = kx

Where 'k' is called the constant of proportionality.

In our case,

The given equation is

y = 12x

comparing with the equation y = kx, we can say

k = 12 which is the constant of proportionality.

Therefore, we conclude that:

The  constant of proportionality k = 12

Hence, option A is true.

Answer:

[tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex]

Step-by-step explanation:

To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.

[tex]\cos\theta[/tex] is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.

We can use Pythagorean's Theorem to find the hypotenuse (let [tex]c[/tex] represent the length of the hypotenuse):

[tex]10^2+4^2=c^2[/tex]

[tex]100+16=c^2[/tex]

[tex]116=c^2[/tex]

[tex]c=\sqrt{116}[/tex]

Thus, we know the adjacent is 10, and the hypotenuse is [tex]\sqrt{116}[/tex]. This means [tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex].

Answer:

Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

Answer:

y-intercept: -4, slope: -3/2 or -1.5

Step-by-step explanation:

The point where the line goes through the y axis has y coordinate of -4 so that is the y-intercept.

The line goes down 3 units every 2 units to the right. The slope is rise over run, so that makes the slope -3/2.
