Step-by-step explanation:

I am not so sure.

5 + 8 + 1 + 2 + 10  =  26 (divided by) 5 = 5.2

The mean and the standard deviation of the data set is 5.2 and 3.429.

The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.

We have,

Data:  {5, 8, 1, 2, 10}.

So, the mean of data

= (5+ 8 + 1 + 2 +10)/ 5

= 5.2

Then, the Value of Deviations

-0.2, 2.8, -4.2, -3.2, 4.8

So, the variance is

= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5

= 11.76

And, Standard deviation is

= 3.429

Answer:

−21

Step-by-step explanation:

=12s5t−6t4−6s−21

(-5s¹²)/ (2t³³) is the Simplified form of the Given equation.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an equation [tex](\frac{5s^{2}t^{-7} }{-2s^{-2}t^{4} })^{3}[/tex]

Simplifying using PEMDAS

First, we will solve the power

=> (-5/2 s²⁺² t⁻⁷⁻⁴)³

=> (-5/2 s⁴ t⁻¹¹)³

=> (-5s¹²)/ (2t³³)

Therefore, the Simplified notation of the Given equation is (-5s¹²)/ (2t³³).

Answer:

There are 27 different possible outcomes.

Step-by-step explanation:

Assuming that you have 3 different stocks:

First, we need to find the number of events and the number of possible outcomes for each event.

Here we can assume that each one of the stocks is a event, and the number of possible outcomes for each one are:

Stock 1: 3 options (up, down, stay)

Stock 2: 3 options (up, down, stay)

Stock 3: 3 options (up, down, stay)

The total number of possible outcomes is equal to the product of the numbers of options for all the events.

Then the total number of possibilities is:

C = 3*3*3 = 27

Answer:

Step-by-step explanation:

The easiest and most proper way to approach this task is to combine like terms inside parentheses:  (24x + 7 – 12x) => (12x + 7).

Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7).  This is an acceptable answer.  There is the option of carrying out the multiplication, which results in

3x + 7/4, which is another acceptable answer.

Answer:

let angle e be x

x+4x+10=180°[by linear pair]

5x+10=180°

5x=180-10

5x=170

x=170/5

x=34

angle E=34°

angle E+angle C+angle D=180°[by angle sum property]

34°+70°+2x=180°

104°+2x=180°

2x=180°-104

2x=76°

Answer:

- 362.5t + 1100

Step-by-step explanation:

Given :

Value, = v ; time, = t

t1, v1 = (0, 1100)

t2, v2 = (2, 375)

Slope, m = v2 - v1 / t2 - t1

m = (375 - 1100) / (2 - 0)

m = - 725 / 2

m = - 362.5

v - v1 = m(t - t1)

v - 1100 = - 362.5(t - 0)

v - 1100 = - 362.5t

v = - 362.5t + 1100

Answer:

Cost of 1 bushes = a = $9

Cost of 1 tree = b = $73.5

Step-by-step explanation:

Given:

13 bushes and 4 trees cost = $411

Missing;

6 bushes and 2 trees cost = $201

Find:

Value of bushes and tree

Computation:

Cost of 1 bushes = a

Cost of 1 tree = b

So,

13a + 4b = 411 ...........eq1

6a + 2b = 201 ................eq2

From Eq1 and Eq2

Cost of 1 bushes = a = $9

From eq 1

13a + 4b = 411

13(9) + 4b = 411

Cost of 1 tree = b = $73.5

Answer:

A = 3x^2 - 2x - 1

Answer:

x = 24°

Step-by-step explanation:

the sum of the interior angles in a triangle = 180°

so:

(2x + 5°) + 64° + 3x - 9° = 180°

combine like terms:

5x + 60° = 180°

subtract 60° from each side of the equation:

5x = 120°

x = 24°

Answer:

1.25 m

Step-by-step explanation:

Given that :

Initial height of drop = 20 meters

Rebound after each drop = 1/2 of height

Height after 4th rebound = 5th term of a geometric series

An = a1 * r^(n-1)

a1 = first term = initial drop height

r = common ratio = ratio of rebound per drop = 1/2 = 0.5

A5 = 20 * 0.5^(5 - 1)

A5 = 20 * 0.5^4

A5 = 20 * 0.0625

A5 = 1.25 m

Hence height after 4 reboubd = 1.25 m

Using another method :

1st bounce height = 20 * 0.5 = 10

2nd bounce height = 10 * 0.5 = 5

3rd bounce height = 5 * 0.5 = 2.5

4th bounce height = 2.5 * 0.5 = 1.25

Answer:

  C  The cost of living will increase by approximately 5% each year

Step-by-step explanation:

If we assume your function is ...

  [tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]

Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.

Noah's cost of living is increasing about 5% per year.
