We want to determine the simple interest rate.

First, find the amount paid as interest:

The point estimate of the population mean is 9

The point estimate of the population standard deviation is 2.83

Part a

Point estimate of population mean:

Given the sample data is 5,8,10,7,10,14

Number of samples, n is 6

Population mean=[tex]\frac{\sum x }{n}[/tex]

                           =(5+8+10+7+10+14)/6

                           =54/6

                           =9

Point estimate of mean=9

Part b

Point estimate of population standard deviation:

Mean=9

Data (x)     (x-mean)^2

5                16

8                1

10               1

7                 4

10               1

14               25

Total           48

Standard deviation=√(x-mean)^2/n

                               =√48/6

                               =√8

                               =2.83

Step-by-step explanation:

100% = $250

1% = 100%/100 = 250/100 = $2.50

the price decreased by

250 - 180 = $70

how many % are $70 ?

as many as how many times 1% ($2.50) fits into $70 :

70 / 2.50 = 28%

it changed (decreased) by 28%.

Model P televisions made up 12 of the 40 televisions when Quick Sell outlet sold a total of 40 television, each of which was either a model P television or a model Q television.

Price plus quantity equals revenue.

Let x be the quantity of sold TVs of model p.

40 - x units of the model q TV would have been sold.

Profits from model p TV sales are

px

Sales of the type q TV bring in money.

(40 - x)q

Total income equals px plus (40 - x)q

The average price calculation formula is written as

Total revenue / total number of TVs sold equals average price.

The 40 televisions sold for an average (arithmetic mean) price of $141. It follows that

141 = (px + (40 - x)q)/40

141 × 40 = px + (40 - x)q

5640 = px + (40 - x)q

p = q - 30

5640 = x(q - 30) + (40 - x) (40 - x)

q

30x + 40q - xq = 5640

5640 = - 30x + 40q

Since q = 120,

5640 = - 30x + 40 × 120

5640 = - 30x + 4800

5640 - 4800 = - 30x

840 = - 30x

x = 840/- 30 = - 28

Q cannot equal 120 since x cannot be negative.

Again,

5640 = px + (40 - x)q

If q = 30 + p, then

5640 = px + (40 - x)(30 + p)

5640 = px + 1200 + 40p - 30x - px

5640 = 1200 + 40p - 30x

Therefore,

If p = 120, then

5640 = 1200 + 40 × 120 - 30x

5640 = 6000 - 30x

30x = 6000 - 5640

30x = 360

x = 360/30

x = 12

Therefore, out of 40 televisions 12 tv are of model p

Using the concept of area, we got 165 bags is the smallest number of bags there groundskeeper must buy to cover the circular field.

The branch of mathematics which deals with measuring is known as Mensuration. It was basically first used for land surveys and other civic works in  Egypt. The father of mensuration is known as Archimedes. Mensuration is a discipline of mathematics which studies the measurements of various geometrical forms  possible and their areas, perimeters, and volumes, among other things.

Diameter of the field = 290 feet, radius = 145 feet

Area of the circular field =[tex]\pi r^{2}[/tex]

=>[tex]\pi[/tex]×145×145 =66018.5 square feet.

No of bags to be brought = 66018.5/400=165bags,

The values of the vectors of AB = b - a , MN = 29a - b/2 and MP = b/2 + (k + 1)( b - a)

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

We have been given that OB = b and OA = a

From ΔAOB we have;

OB + BA + AO = 0

b + (- AB ) -a = 0

AB = b - a

Now from ΔMNO we have;

MN + NO + OM = 0

MN + ( -ON) + OB/ 2 = 0

MN - (OA + AN ) + b/2 = 0

MN - ( a + 30a) + b/2 = 0

MN = 29a - b/2

Now from ΔMBP , we have;

MB + BP + PM = 0

OB/2 + (BA - PA) + PM = 0

b/2 + ( - AP/k + AP) + PM = 0

b/2 + ( -kAB /k + kAB) + PM = 0

b/2 + ( k AB + AB ) + PM ) = 0

May's total profit given the revenue, fixed cost and variable cost is $250.

Profit is when the difference between revenue and total cost is positive. A loss is earned when the difference between revenue and total cost is negative.

Total cost is the sum of fixed cost and variable cost. Fixed cost is the cost that remains constant regardless of the level of output. Variable cost changes based on the level of output.

Total cost = variable cost + fixed cost

$9,000 + $300 = $9,300

Profit = revenue - total cost

it is relatively simple to solve :

x liters of 1% had to be mixed with 12 liters of 4% to get 12+x liters of 2%

x×0.01 + 12×0.04 = (12+x)×0.02 = 12×0.02 + x×0.02

12×0.02 = x×0.01

x = 12×0.02/0.01 = 12×2 = 24 liters

so, 24 liters of 1% had to be added to the 12 liters of 4% to get a 2% mixture (12 + 24 = 36 liters).

The algebraic expression is equivalent to the expression below is 36x+110

According to the Distributive Law, multiplying a number by a collection of numbers is equivalent to performing each multiplication independently.

For instance, given the standard expression C(D + E). Using the distributive law;

C(D + E) = CD + DE

Using this rule to the given expression shown below;

11(4x + 10) - 8x

Apply the distributive property;

11(4x + 10) - 8x

11(4x) + 11(10) - 8x

44x + 110 - 8x

The measure of the angles are 56.25° and 33.75°.

The value in a complementary angle is equal to 90°.

Let the first angle = x

The second angle will be: 1 - (40% × x) = 1 - 0.4x = 0.6x

Therefore, they'll be added together as follows:

x + 0.6x = 90°

1.6x = 90°

Divide

x = 90/1.6

x = 56.25

The second angle will be:

= 0.6x

Since x = 56.25, this will be used in the illustration below.

= 0.6x

= 0.6 × 56.25

x = 33.75
