The drawn bedroom ookis like this

as this is drawn to scale, to find the area of the real bedroom we should find the lengths of the real bedroom first. We are told that every 2cm represent 5m. So, we will define our scaling factor as

as every 2 cm represent 5m. Now, to calculate the real lengths, we simply take the scaled lengths and multiply it by the scaling factor. So we have s

so the real bedroom looks like this

which is a rectangl of height 210m and base 5m. Recalling tha the area of a rectangle is the product of it s height and its base, we have that the area of this rectangle would be

1) Examining the expressions, let's factorize them taking the LCM out of the parentheses

5a +10 The LCM 5,10 is 5

5(a +2)

16k +12 The LCM 16, 12 is 4

4(4k +3)

2) So the answers are 5(a +2) and 4(4k +3) notice that if we distribute those factors you'll get the initial form.

The probability of dialling one number of phones keypad and it being a number greater or equal to 0 is 100% as there is no smaller number than 0 in the keypad.

Probability is defined as the ratio of favorable outcomes to all possible outcomes of an event. The proportion of positive outcomes, or x, for an experiment with 'n' outcomes can be expressed. The following formula can be used to determine the likelihood of an event.

Probability (Event) = Positive Outcomes/Total Outcomes = x/n

Let's say that we need to make a rain prediction. Both "Yes" and "No" are acceptable responses to this query. Both rain and no rain are possible outcomes. Probability can be used in this case.

H0 : p0 = 0.12

H1 : p0 ≠ 0.12

Sample size, n = 600 ; α = 0.05

Zstatistic < Zcritical ; reject H0

P = 95/600 = 0.16

Zstatistic = (p - p0) ÷ sqrt((p0(1 - p0)) /n)

Zstatistic = (0.16 - 0-12)/ sqrt((0.12(0.88))/600)

Zstatistic = 3.01

Answer:

4x + 12

Explanation:

The perimeter of a rectangle can be calculated as two times the length plus two times the width. So, the perimeter is:

Perimeter = 2(x + 2) + 2(x + 4)

Applying distributive property, we get:

Perimeter = 2*x + 2*2 + 2*x + 2*4

Perimeter = 2x + 4 + 2x + 8

perimeter = 4x + 12

Therefore, the perimeter is 4x + 12

The equation of the polynomial is P(x) = -(x - 1)²(x + 5)(x - 4)

The given parameters are

The equation of the polynomial can be calculated as

P(x) = a * (x - zero)^ multiplicity

So, we have

P(x) = a * (x - 1)² * (x + 5) * (x - 4)

This gives

P(x) = a * (x - 1)²(x + 5)(x - 4)

From the question, we have

y-intercept = 20

This means that

P(0) = 20

So, we have

20 = a * (0 - 1)²(0 + 5)(0 - 4)

Evaluate products

20 = a * -20

Divide

a = -1

Substitute a = -1 in P(x) = a * (x - 1)²(x + 5)(x - 4)

P(x) = -(x - 1)²(x + 5)(x - 4)

Hence, the equation is P(x) = -(x - 1)²(x + 5)(x - 4)

The total cost of the television with sales tax included is $ 845.81

What is a percentage and how do we calculate it?
A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it. No dimension exists for percentages. Thus, it is referred to as a dimensionless number.
Mathematically, Percentage formula = (Value/Total value) × 100

Given, the listed price of the television = $ 784.98
Percentage value of sales tax on purchase = 7.75
Using the mathematical formula in the above literature, we get
7.75 = (Value/784.98) × 100 ⇒ Value = (7.75*784.98)/100 = 60.83
Thus, total cost of the television will be:
Listed price + Value = $(784.98 + 60.83) = $ 845.81
Therefore, the total cost of the television with sales tax included is
$ 845.81

The equation of the line is y = (1/5)x - 8/5, the slope of the line is 1/5 and the y intercept is -8/5

The slope intercept form is

y = mx + b

Where m is the slope of the line

b is the y intercept

The  perpendicular line equation is

y = -5x-8

The slope of the perpendicular line = -5

The slope of the main line = -(1/-5)

= 1/5

The line is passing through the point (-2,2)

y = mx + b

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

-2 = -2/5 +b

-2 +2/5 = b

b = -8/5

The equation of the line

y = (1/5)x - 8/5

Hence, the equation of the line is y = (1/5)x - 8/5, the slope of the line is 1/5 and the y intercept is -8/5
