Q3 or upper quartile for the data 2,4,6,8,10,12 is 10

Q3 or upper quartile is an statistical term that separates the highest 25 percent data from lowest 75 percent data.

For finding quartile first arrange the given data into ascending order.

Find the median of the data then the median divides the data into two potions . the median of the upper half of data is the upper quartile.

Or if the total no of terms are n then Quartile formula for upper quartile is  

  = (n+1)3/4   term

Given data is 2,4,6,8,10,12 which is already arranged in ascending order and no of terms are n=6

Median of this data = ( 3rd term + 4th term)/2 =(6+8)/2=7

7 divides the data into two halves 2,4,6 and 8,10,12

Upper half is 8,10, 12 as this data has odd terms thus median will be the middle term

Median is middle term of 8,10,12 that is 10

Therefore, Q3 or the upper quartile of the given data is 10

The cost of the wool insulation required for the loft floor is £149.16498

The given parameters are

Roll of wool = 114 cm by 5.2 m

One roll = £19.65 per roll

The area of one roll is calculated as

Area = Length * Width

So, we have

Area = 114 cm x 5.2 m

Convert cm to m

Area = 1.14 m x 5.2 m

Evaluate the product

Area = 5.928 m^2

The cost of the required area of loft floor is

Total cost = Unit cost/Area of 1 roll x Area of floor

This gives

Total cost = £19.65/5.928 * 4.5 * 10

Evaluate the product

Total cost = £149.16498

Hence, the cost of the wool insulation required for the loft floor is £149.16498

The equation of the line with slope 4 which goes through the point (8,5) will be y = 4x - 27.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

If the slope of the equation of a line is 4, then the equation of the line will be

y = 4x + c

The equation of the line is passing through (8, 5), then the value of c will be

5 = 4(8) + c

5 = 32 + c

c = 5 - 32

c = - 27

Then the equation of the line will be

y = 4x - 27

The company must sell 1899 DVDs each day to make a profit.

An owner's income from a successful manufacturing process producing goods for the market is referred to as a profit (business).

The cost for supplies is $0.80 per DVD.

Let the company manufactured and sold x DVD s.

Now , total cost for x DVDs = 0.80 x + 1500

Total sell price for x DVDs = 1.59x

Profit = Sell price - cost price

Profit = 1.59x - 0.80x - 1500

profit = 0.79 x - 1500

Now the profit is made. Therefore profit>0

∴ 0.79 x - 1500 > 0

or , x > 1500 ÷ 0.79

or, x > 1898.734

Hence the company need to sell 1899 DVDs to make a profit.

The amount after 4.5 years for the principal amount $ 5000 at 4 % interest compounded annually will be $ 5956.13.

We are given that:

Principal = p = $ 5000

Interest rate = r = 4%

Compounding Annually

Time = n = 4.5 years

Now, we know that the formula for compound interest is:

Amount (A) = p ( 1 + r )ⁿ

Substituting the values in the formula, we get that:

A = 5000 ( 1 + 0.04)⁴°⁵

A = 5000 (1.04)⁴°⁵

A = 5000 (1.19)

3/5 hours or 36 minutes

Step-by-step explanation:

John could mow three of these lawns in three hours (3/1 = three), while Sam could only mow two in three hours (3/1.5 = two). Therefore, the two of them could cut 5 lawns in 3 hours (3+2). Together, they can cut the same lawn in three and a half hours, or 36 minutes.

The slope of the line relating Alyssa's sales to earnings is given by 0.15,the equation that gives Alyssa's daily earnings based on her total sales is  y = 0.15x +80,the y-intercept of the line represents the part of Alyssa's earnings that doesn't depend on sales. It is Alyssa's fixed daily wage and the y-intercept is 80.

The slope intercept form of a line is y=mx+c, where m is the slope of line.

a) The slope of the line relating Alyssa's sales to earnings is given by

  slope = (change in earnings)/(change in sales)

Using the first two table entries, the slope is calculated as

  slope = (110 -80)/(200 -10) = 30/200 = 0.15

The first entry in the table shows the y-intercept, the value of earnings (80) for zero sales. The slope-intercept form of the equation for a line is

  y = slope*x + y-intercept

To answer the first question, we put the slope and intercept values in the appropriate spots in the equation.

The equation that gives Alyssa's daily earnings based on her total sales is  y = 0.15x +80

b) The y-intercept of the line represents the part of Alyssa's earnings that doesn't depend on sales. It is Alyssa's fixed daily wage.

c) The slope of the equation represents Alyssa's commission rate.

d) The y-intercept is 80.

Therefore The slope of the line relating Alyssa's sales to earnings is given by 0.15,the equation that gives Alyssa's daily earnings based on her total sales is  y = 0.15x +80,the y-intercept of the line represents the part of Alyssa's earnings that doesn't depend on sales.

2b) x < - 3

2e) x < 3 or x < -3

Step-by-step explanation:

Format for quadratic equations (the only difference in quadratic equations is that the equal sign is replaced with any of the inequality symbols (< , > , ≥ , and ≤)

ax² + bx + c = 0

- To factor quadratic inequalities (we're using 2b) as a demonstration)

1) Find two numbers that make the product equal to a×c (1×9) which is 9 and the sum that equals to b which is 6. Those two numbers in this case is positive 3 and positive 3

2) Spilt the middle term with those two numbers which are positive 3 and positive 3 so the inequality x² + 6x + 9 is going to become x² + 3x + 3x + 9

3) Take the common terms and simplify the common terms in this case the common terms are x and + 3 so it can be factored as (x + 3) and (x + 3)

To find each x make each term greater than 0 so it would be x + 3 < 0 and x + 3 < 0

4) Solve for x (it is the same way to solve x in inequalities as it were for equations which is doing inverse operations to order to islolate x) It would be x + 3 - 3 < 0 - 3 which is x < - 3

2e)

1) You essentially do the same steps for solving this question too but a shortcut way of doing factoring is to do the perfect square method which is to look a c which is 9 and if its a perfect squares you can factor it as (x+3) and (x-3) since not only is the 9 negative both of these terms when added cancel out each other.

2)To find x make everything < 0 so it would be x + 3 < 0 and x - 3 < 0

3) Solve for x it would be x + 3 - 3 < 0 - 3 and x - 3 + 3 < 0 + 3 . The roots are x < - 3 or x < 3

The fatality rate per 100,000 is 205.23.

In mathematics, a rate of something is simply the ratio between two related quantities which are expressed different units. While expressing the units of any rate, the word "per" is used to distinguish the units of the two measurements used to calculate the rate.  

Here, we are given that a country has a population of 2.1 million.

2.1 million can be written as- 2,100,000

The number of fatalities experienced by the country = 4,310

This means that there where 4,310 fatalities per 2.1 million of the population.

The number of fatalities per 100,000 will be given as-

4,310/ 2,100,000 × 100,000

expanding it further we get-

4,310/ 21

The equation of line in slope intercept form described from given table will be equal to y = -2x + 1

What is the slope intercept form of a line ?

The equation of a line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

From the given figure we can find out that the points are (x1.y1) = (-2 , 5) and (x2 , y2) = ( -1 , 3).

The equation of line in slope intercept form

y = mx + c

Where m is the slope, and c is the y-intercept.

We have points (-2, 5) and (-1,3). Thus , the slope (m) will be :

m = ( [tex]y_{2} - y_{1}[/tex] ) /( [tex]x_{2} - x_{1}[/tex] )

m = ( 3 - 5 ) / ( -1 + 2)

m = -2

Using this value to find out the equation of line we get :

y = -2x + c

Point (-2,5) means that when x = -2 then y = 5 , and we use this data to find value of c , which is the y- intercept ;

5 = -2 × -2 + c

c = 5 - 4

c = 1

So , in slope intercept form the equation of line will be ;

y = -2x + 1
