Answer:

2%

Step-by-step explanation:

Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.

Now that we know the simple interest, we can now get the simple interest rate or simple percent interest per year by dividing $4 by $200.

Let's change 0.02 into a percentage.

This means that every year, her investment will earn a 2% simple interest.

Answer:

the answer would be 70/100 in fraction form, 70% in percent, and (i believe) 0.7 min decimal form. Hope this helps!

Answer:

70 out of 100 is the ratio  70 Over 100 apostrophe  , so it represents 70%.  70 Over 100  can be reduced by dividing the numerator and the denominator by 10 to get the reduced fraction 7 Over 10. Dividing 7 by 10 results in the decimal equivalent 0.70.

The distinction between statistical significance and practical importance is best illustrated by:

C. In 50,000 births, the new vaccine reduced the incidence of infant mortality in Morrovia significantly from 14.2 deaths per 1000 births to 10.3 deaths per 1000 births.

Step-by-step explanation:

                                   Current state     Previous state     Change

A.  Textbooks sold      240/400 (0.6)   220/330 (0.67)     0.07

B.  Life of hard disk     250,000 hrs     240,000 hrs         0.04

C.  Infant mortality      10.3 per 1000    14.2 per 1000       0.27

D.  Cruising range      4,000 miles       3,975 miles          0.006          

Statistical significance, which depends on the p-value established before the test, relates to whether an effect exists, while practical significance determines the magnitude or size of the effect.  A statistical test cannot tell whether the magnitude is large enough to be important.  Mathematically, the change can be determined, which establishes the practical significance or importance of the change.

Given that,

An expression [tex]\dfrac{1}{4}-\dfrac{3}{5}[/tex]

To find,

The value of above expression.

Solution,

We have,

[tex]\dfrac{1}{4}-\dfrac{3}{5}[/tex]

The LCM of 4 and 5 is 20.

[tex]\dfrac{1}{4}-\dfrac{3}{5}=\dfrac{(5)-4(3)}{20}\\\\=\dfrac{5-12}{20}\\\\=\dfrac{-7}{20}[/tex]

So, the required answer is [tex]\dfrac{-7}{20}[/tex].

Answer:

The values of x and y that will minimize the cost is 15 ft and 5 ft respectively and the minimum cost will 3,375

Step-by-step explanation:

With a 1125 ft^3 open-top rectangular tank with a square base x ft on a side and y ft deep is to be built with its top lush with the ground to catch runoff water, x is the length, y is the height;

x^2*y = 1125

y = 1125/x^2 ----(1)

The total cost of c = 5(x^2 + 4xy) + 10xy

Then,

c = 5(x^2 + 4x*(1125/x^2)} + 10x*(1125/x^2)

c = 5x^2 + 22,500/x + 11,250/x

c = 5x^2 + 33,750/x

To minimize the cost of c, find the derivatives of c; c'

c' = 10x - 33,750/x^2

c' = (10x^3 - 33,750)/x^2

c'(x) = 0; 10x^3 = 33,750

x = ³√33,750 = 15

x = 15; y = 1125/x^2

y = 1125/15^2 = 5

(x,y) = (15,5)

c = 5x^2 + 33,750/x

c = 5*15^2 + 33,750/15 = 3,375

The values of x and y that will minimize it is 15 ft and 5 ft respectively and the minimum cost will 3,375

The values of x and y that will minimize the cost is 15ft and 5ft. The minimum cost is 3,375

We have volume of a rectangular tank = 1125 ft^3

Side of a rectangular tank = x ft and

Length of a rectangular tank =y ft  

So, [tex]x^2y = 1125[/tex]

[tex]y = \frac{1125}{x^2} ...(1)[/tex]

The total cost of rectangular tank (c) = [tex]5(x^2 + 4xy) + 10xy[/tex]

 [tex]c = 5(x^2 + 4x(\frac{1125}{x^2} ) )+ 10x(\frac{1125}{x^2} )\\c = 5x^2 +\frac{22,500}{x} + \frac{11250}{x} \\c = 5x^2 + \frac{33750}{x}[/tex]

Differentiating it w.r.t x, we get

[tex]c' = 10x - 33,750/x^2\\c' =\frac{10x^{3}-33750 }{x^{2} } \\c'(x) = 0\\10x^3 = 33,750\\x = \sqrt[3]{33,750} \\ = 15\\x = 15; y = \frac{1125}{x^2} \\y = \frac{1125}{15^{2} } \\= 5\\(x,y) = (15,5)\\c = 5x^2 + \frac{33750}{x} \\c = 5(15)^2 + 33,750/15 \\= 3,375[/tex]

The values of x and y that will minimize the cost is 15 ft and 5 ft and the the minimum cost is 3,375.

Answer:

Step-by-step explanation:

Answer:

$1.60

$2.88

Step-by-step explanation:

To find the selling price of the distributor and the retailer, we first need to find how much the distributor sells each pack of cards.

To find the selling price we use the formula.

Selling Price = Cost + Markup

Cost = $0.80

Markup rate = 100% or 1

Selling Price = 0.80 + (0.80*1)

Selling Price = $1.60

So the distributor sells each pack of cards at $1.60 to the retailer.

Now to find the selling of the retailer, we need to use the selling price of the distributor.

Cost = $1.60

Markup rate = 80% or 0.80

Selling price =  1.60 + (1.60 * 0.80)

Selling price = $2.88

So the retailer sells each pack of cards at $2.88 to the customers.

Answer:

A = $1.60

B = $2.88
