Answer:

4.78125

Step-by-step explanation:

Step 1

Find the mean

Mean = Sum of Terms/Number of Terms

Mean = 7+5+ 16+20+ 17+ 9+ 18+ 15/8

= 107/8

= 13.375

Step 2

Find the Mean Absolute Deviation

Mean Absolute Deviation formula = |x - Mean|/n

Mean Absolute Deviation =[ |7 - 13.375| +| 5 -13.375|+ |16 - 13.375| + |20 - 13.375| +| 17 - 13.375| + |9 - 13.375 | +| 18 -13.375|+|15 - 13.375|] /8

Mean Absolute Deviation = 4.78125

Therefore, the Mean Absolute Deviation (M.A.D.) for these students = 4.78125

Answer: [tex]\left\{x | x \in \mathbb{R}, \ -5 \le x < 16\right\}[/tex]

=======================================================

Explanation:

We have some number x such that x is a real number, so we write that as [tex]x \in \mathbb{R}[/tex] which is saying "x is in the real number set".

The portion [tex]-5 \le x < 16[/tex] is how x is restricted. This means x can be -5 or larger, but also must be smaller than 16.

This is from the interval notation [-5, 16). The square bracket means we include -5 as part of the interval, but we exclude 16 because of the curved parenthesis.

The curly braces surrounding everything indicates that we have a set of values.

-----------------

Side note:

If x is an integer, then we can get this roster set {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15} showing all of the integers between -5 and 16, including -5 but excluding 16.

Though chances are your teacher will want you to stick to real numbers rather than just integers.

When a fraction equals zero

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 y-18x-12

 ———————— • 6 = 0 • 6

    6    

Now, on the left hand side, the  6  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  y-18x-12  = 0

Equation of a Straight Line

4.2     Solve   y-18x-12  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-18x-12  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 12/1 so this line "cuts" the y axis at y=12.00000

 y-intercept = 12/1  = 12.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 2/-3 Our line therefore "cuts" the x axis at x=-0.66667

 x-intercept = 12/-18 = 2/-3  = -0.66667  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 12.000 and for x=2.000, the value of y is 48.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 48.000 - 12.000 = 36.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = 36.000/2.000 = 18.000  

Geometric figure: Straight Line

 Slope = 36.000/2.000 = 18.000

 x-intercept = 12/-18 = 2/-3 = -0.66667

 y-intercept = 12/1 = 12.00000

Answer:

9.9 quarters or Approximately ≈ 10

Step-by-step explanation:

Let n = number of nickels

d =number of dimes

q = number of quarters

n + d + q = 30 coins....... Equation 1

1 nickel = $0.05

1 dime = $0.10

1 quarter = $0.25

0.05n + 0.10d + 0.25q =$ 3.65.......Equation 2

There are twice as many nickels as there are dimes.

Hence

n = 2d

n + d + q = 30 coins

2d + d + q = 30 coins

3d + q = 30 coins........Equation 3

3d = 30 - q

d= 30 - q/3

0.05n + 0.10d + 0.25q =$ 3.65

Since n = 2d

0.05(2d) + 0.10d + 0.25q = $3.65

0.10d + 0.10d + 0.25q = 3.65.........Equation 4

Substitute 30 - q/3 for d in Equation 4

0.10(30 - q/3) + 0.10(30 - q/3) + 0.25q = 3.65

= 3 - 0.10q/ 3 + 3 - 0.10q/3 + 0.25q

(3 - 0.10q) + (3 - 0.10q) + 3(0.25q)/ 3 = 3.65

Cross multiply

(3 - 0.10q) + (3 - 0.10q) + 3(0.25q) = 3 × 3.65

3- 0.10q+ 3 - 0.10q + 0.75q = 10.95

6 - 0.20q + 0.75q = 10.95

0.50q = 10.95 - 6

0.50q = 4.95

q = 4.95/0.50

q = 9.9 quarters

Therefore, the numbers of quarters is approximately ≈ 10 quarters

Answer:

OB = 8

OC = 8

OA = 8

AC = 16

BD = 16

OD = 8

Step-by-step explanation:

Given, rectangle ABCD, with diagonals AC and BD, and OC = 3x – 4, OB = x + 4,

thus, since diagonals of a rectangle are equal, therefore, AC = BD.

Invariably, 2*OC = 2*OB

Thus, [tex] 2(3x - 4) = 2(x + 4) [/tex]

Solve for x

[tex] 6x - 8 = 2x + 8 [/tex]

Add 8 to both sides

[tex] 6x - 8 + 8 = 2x + 8 + 8 [/tex]

[tex] 6x = 2x + 16 [/tex]

Subtract 2x from both sides

[tex] 6x - 2x = 2x + 16 - 2x [/tex]

[tex] 4x = 16 [/tex]

Divide both sides by 4

[tex] \frac{4x}{4} = \frac{16}{4} [/tex]

[tex] x = 4 [/tex]

OB = x + 4 = 4 + 4 = 8

OC = 3x - 4 = 3(4) - 4 = 12 - 4 = 8

OA = OC = 8

AC = 2*OC = 2*8 = 16

BD = 2*OB = 2*8 = 16

OD = OB = 8

length=29.085 in.

Step-by-step explanation:

width=x

length =x+5.88

Perimter=x+x+x=5.88+x+5.88=104.58

4x+11.76=104.58

4x=104.58-11.76

4x=92.82

x=23.205

width=x=23.205 In.

length=x+5.88=23.205+5.88=29.085 in.

Answer:

7 days

Step-by-step explanation:

If you are using [tex]\frac{5}{6}[/tex] of a bag of coffee per day, and you have [tex]5 \frac{5}{6}[/tex] bags of coffee, you want to find how many times [tex]\frac{5}{6}[/tex] goes into [tex]5 \frac{5}{6}[/tex].

This can be found using division.

First let's convert  [tex]5 \frac{5}{6}[/tex] into an improper fraction:

[tex]5 \frac{5}{6} = \frac{(6\cdot5) + 5}{6} = \frac{35}{6}[/tex]

Now we set up our division equation:

[tex]\frac{35}{6} \div \frac{5}{6}[/tex]

To divide, we multiply by the reciprocal, so:

[tex]\frac{35}{6} \div \frac{5}{6} = \frac{35}{6} \cdot \frac{6}{5} = \frac{210}{30}[/tex]

Dividing both the numerator and denominator of [tex]\frac{210}{30}[/tex] by 30 gets us [tex]\frac{7}{1}[/tex], which is just 7.

Hope this helped!

Answer:

7 days or 1 week

Step-by-step explanation:

First, know what the equation is. In this case, it's 5 5/6 divided by 5/6, since you need to divide the amount you have by how much you use every day to find out how many days it will last.

The equation is 5 5/6 ÷ 5/6, but since that is harder to solve, turn the 5 5/6 into an improper fraction: 35/6

Now, just solve 35/6 ÷ 5/6, so this means you have to flip your second number and multiply instead divide when dividing fractions, so the new equation is 35/6 ×6/5

That equals 210/30, and if you take out both the 0s (cancel them out), you get 21/3 and after simplifying that, you get 7/1, which is basically 7.

Answer:

B 6/11

Step-by-step explanation:

The answer for edge 2021 is.....c-6/11

Answer:

14 years

Step-by-step explanation:

To find the answer, you have to use the formula to calculate the time period:

t=(1/r)*(A/P-1), where:

t= time period

r= rate of interest=5%

A= accrued amount=$8,500

P= principal amount=$5,000

Now, you can replace the values in the formula:

t=(1/0.05)*(8,500/5,000-1)

t=20*0.7

t=14

According to this, the answer is that the money has been 14 years in the account.

Answer:

The percentage increase in A is 44%. The percentage increase in V is 72.8%.

Step-by-step explanation:

The easiest way to go about solving this problem is to pick your own numbers and plug them into the given equations.

For example, let's say that k = 5 and that r = 10.

[tex]A=kr^{2}[/tex]  ⇒ [tex]A= 5 * 10^{2} =500[/tex]

[tex]V=kr^{3}[/tex] ⇒ [tex]V= 5 * 10^{3}= 5000[/tex]

The question is asking, what is the percentage increase if r is increased by 20%. Our chosen k-value will stay the same but our r-value is going to increase. To find the new value of r, we multiply 10, our current value of r, by 1.2. This gives us a new value for r, which is 12.

[tex]10*1.2=12[/tex]

Now, we are going to plug in our new r-value and our k-value into the given equations. k = 5; new r = 12

[tex]A=kr^{2}[/tex] ⇒ [tex]A=5*12^{2}=720[/tex]

[tex]V=kr^{3}[/tex] ⇒ [tex]V=5*12^{3}=8640[/tex]

Next, we have to calculate the percentage increase in our values of A and V. To do this, we use the following formula:

[tex]Percentage Increase = \frac{final - initial}{initial} * 100[/tex]

Percentage Increase for A

Initial value: 500

Final Value: 720

[tex]Percentage Increase = \frac{720-500}{500} * 100 = 44%[/tex]

Percentage Increase for V

Initial value: 5000

Final Value: 8640

[tex]Percentage Increase= \frac{8640-5000}{5000} *100 = 72.8%[/tex]

The percentage increase for A is 44% and the percentage increase for V is 72.8%.
