2. Solve this inequality. Show your work. 5.6+2.2.x > 65.6-1.8x

Nitella [24]

Answer: x>15

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality:

(56/10)+(22/10)*x-((656/10)-(18/10)*x)>0

Simplify 9/5

56 22 656 9

(——+(——•x))-(———-(—•x)) > 0

10 10 10 5

Simplify 328/5

56 22 328 9x

(——+(——•x))-(———-——) > 0

10 10 5 5

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

328 - (9x) 328 - 9x

—————————— = ————————

5 5

56/10+22/10.x/5)) >0 (328 - 9x)

Simplify 11/5

56/10+11/5.x/5))->0 (328-9x

Simplify 28/5

28 11x (328 - 9x)

(—— + ———) - —————————— > 0

5 5 5

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

28 + 11x 11x + 28

———————— = ————————

5 5

:

(11x + 28) (328 - 9x)

—————————— - —————————— > 0

5 5

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(11x+28) - ((328-9x)) 20x - 300

————————————————————— = —————————

5 5

Pull out like factors :

20x - 300 = 20 • (x - 15)

20 • (x - 15)

————————————— > 0

Multiply both sides by 5

Divide both sides by 20

Solve Basic Inequality :

Add 15 to both sides

x > 15

What is the Pythagoras Theorem?

Tomtit [17]

this is the definition of it:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

Hi there!

Parabola x² = 12y

→ x² = 4ay

→ 4a = 12

→ a = 12÷4

→ a = 3

So, the co-ordinates of the focus is:-

S(0,a)=(0,3)

→ Let AB be the latus rectum of the given parabola.

→ Coordinates of end-points of latus rectum are (-2a,a), (2a,a)

→ Coordinates of A are (-6,3), while B's coordinates are (6,3).

→ ∆OAB are O(0,0), A(-6,3), B(6,3)

Area of ∆OAB is :-

(Solving part attached as image)

=> 18 unit² is the required answer.

the u.s. census bureau needs to estimate the median income of males in the u.s., they collect incomes from 2500 males. state the

Shkiper50 [21]

Individual : a male in the United States

Variable : income

Population : All males in the United States

Sample : 2500 males of which the information is collected

Parameter : Median income of males in the U.S

Statistic : Median income of the 2500 males sampled

Any quality, amount, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable.
A sample is a subset of units chosen to represent all the individuals in a population. Because just a portion of the population was counted, it is only a partial enumeration. To estimate the characteristics of the total population of interest, data from the sampled units is used.
A statistic is a numerical representation of a sample, whereas a parameter is a numerical representation of the entire population.
