Answer:
<u>The quantity is US$ 58, which 6.5% is US$ 3.77 </u>
Step-by-step explanation:
Number = x
6.5% of x = $ 3.77
6.5% = 0.065 = 65/1,000 = 13/200 (Dividing by 5)
3.77 = 3 + 77/100 (We can't simplify 77/100)
Thus,
13/200 * x = 3 77/100
13x/200 = 377/100
13x = 754 (Multiplying by 200 at both sides)
x = 754/13 (Dividing by 13 at both sides)
<u>x = 58</u>
The perimeter of the rectangle is the sum of its dimensions
The dimensions that minimize the perimeter are 
The area is given as:

Let the dimension be x and y.
So, we have:

Make x the subject

The perimeter is calculated as:

Substitute 

Expand

Differentiate

Set to 0

Rewrite as:

Divide both sides by -1

Multiply y^2

Divide by 2

Take square roots of both sides


Substitute
in 



Hence, the dimensions that minimize the perimeter are

Answer: The standard error of the sample mean = 0.44
Step-by-step explanation:
Standard error of the sample mean =
<em> , where </em>
= population standard deviation , n= sample size.
Given : n= 45 ,
grams
The e standard error of the sample mean 

Hence, the standard error of the sample mean = 0.44
So, an isosceles triangle has 2 equal sides, we will call them x.
The base can be modeled by 3+x
So, the perimeter is equal to x + 3+x + x
So
15.6 = 3x + 3
12.6 = 3x
4.2 = x
So, the lengths of the sides are 4.2, 4.2, 7.2
