Is Statistics mathematics or science? Defend your answer.

Mathematics
1 answer:
ohaa [14]2 years ago

Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.

• It is mostly used to find the census, which is maths.

• It is used to find interest rates and other banking terms using statistics, which is again related to math.

• It is also used to find the average people living in a village or panchayat, which is also math.

Therefore I strongly believe that Statistics is Maths.

Thank You!

5x − 8( 1 + 7x ) = −8
xxTIMURxx [149]

Answer:

x = 0

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

5x - 8(1 + 7x) = -8

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute -8:                              5x - 8 - 56x = -8
  2. Combine like terms:                  -51x - 8 = -8
  3. Isolate <em>x</em> term:                            -51x = 0
  4. Isolate <em>x</em>:                                     x = 0

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it is a solution.</em>

  1. Substitute in <em>x</em>:                    5(0) - 8(1 + 7(0)) = -8
  2. Multiply:                               0 - 8(1 + 0) = -8
  3. Add:                                      -8(1) = -8
  4. Multiply:                                -8 = -8

Here we see that -8 does indeed equal -8.

∴ x = 0 is a solution of the equation.

X=1,<br> X^2=X,<br> X^2-1=X-1,<br> (X+1)(X-1)=X-1,<br> X+1=1,<br> X=0<br><br> Where is the mastic?
Alchen [17]

Answer:

You are technically dividing by zero, it breaks math.

In the step (X+1)(X-1)=X-1 → X+1=1.

You divide (X+1)(X-1)=X-1 by (x-1) on both sides to get:

(x+1)(x-1) / (x-1) = (x-1) / (x-1).

Since x = 1,

(x + 1)(x - 1) / (x - 1) = (x - 1) / (x - 1)

becomes (2)(0) / <u>0</u> = 0 / <u>0</u>.

And when you divide by zero, it's undefined since you cannot multiply a number by zero and get a number other than zero, it's undefinable.

This is where limits come in, when you divide by a variable, you have to assumed that is it ≠ 0.

You know that 1 ≠ 2, and 0 ≠ 1, and so on.

As dividing by zero approaches infinity,

1/0.1 = 10, 1/0.01 = 100, 1/0.001 = 1000, 1/0.00..1 = 1000.. → 1/0 → infinity.

1/-0.1 = -10, 1/-0.01 = -100, 1/-0.001 = -1000,

1/-0.00..1 = -1000.. → 1/0 → -infinity.

This suggests that dividing by zero should be infinity.

Therefore infinity = -infinity, Wrong.

When you are dividing, you are really asking yourself, how many times does this number fit into the other number.

1 cannot fit into 0, there isn't anything to fit into. This can also be thought of as:

1 = 0 + 0 + 0 + 0 + 0 + ......

0 + 0 = 0, so 1 ≠ 0.

1.Given the lines shown here, what are two possible equations for this system of equations
ASHA 777 [7]

Answer:

Two possible equations:

y = x + 1\\y = x - 5\\

The system has 0 solution as parallel lines never cross each other.

Step-by-step explanation:

Considering the two lines are parallel, they both have the same slope.

let m be the slope of the two lines:

y = mx + y_{0}\\y=mx+y_{1}

y_{0}, y_{1} are the value on y axis where the two lines cross the axis.

Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.
