Why aren't convenience samples usually representative
of the population?
Answer:
The results of the convenience sampling cannot be generalized to the target population because of the potential bias of the sampling technique due to under-representation of subgroups in the sample in comparison to the population of interest. The bias of the sample cannot be measured.

Karen Gaines invested $10,000 in a money market account with an interest rate of 3.25% compounded semiannually. Three years later, Karen withdrew the full amount to put toward the down payment on a new house. How much did Karen withdraw from the account?
The total amount of money that Karen withdrew from her account three years later is $11,015.48.
How much did Karen withdraw?When an amount earns a compound interest seminannually, it means that the amount invested and interest accured increases in value twice a year.
The formula for calculating future value:
FV = P (1 + r)^nm
FV = Future value P = Present value R = interest rate m = number of compoundingN = number of years$10,000 x (1 + 0.0325/2)^6 = $11,015.48

the piece-wise function is, -x - 5 when x ≠ -2
and when x = -2, the function's value is -2
what that means is when x = -4, the subfunction of -x - 5 is the one to use, because x = -4 is in that range
so f(-4) = -(-4) - 5 => f(-4) = -1.
so the function's graph look more or less like the one below, with a solid line going but with a gap at x = -2.

Give the dimensions of 2 solids with equal surface area and different volume
Two solids with the same surface and different volumes are a cube of side length of 1 unit, and a sphere of radius of 0.69 units.
How to find the two solids?
First, let's define a cube of a side length of 1 unit. The surface of this cube is equal to 6 times the area of one of the faces, or:
S = 6*(1 unit square) = 6 units square.
And the volume is equal to the side length cubed, so we have:
V = (1 unit)^3 = 1 unit cubed.
Now, let's find a sphere with the same surface than our cube. For a sphere of radius R, the surface is:
S = 4*3.14*R^2
Then we must have:
4*3.14*R^2 = 6 units square
R = √(6/(4*3.14)) units = 0.69 units.
And the volume of this sphere is:
V = (4/3)*3.14*R^3 = (4/3)*3.14*(0.69 units)^3 = 1.38 cubic units.
So the sphere has the same surface and more volume.

Madelyn has 4 pairs of red socks, 6 times as many pairs of blue socks 1 as white pairs of socks, and I as many white pairs as red pairs. How many pairs of socks does she have in all? How many socks does Madelyn have?
The Total Number of socks is 10 in all, bear in mind that there is no blue socks hence it will not add to the total amount of socks
Addition of NumbersNote : 1 pais = 2 socks
Given Data
Red Socks = 4 pairs = 4*2 = 8 socks 6 times as many pairs of blue socks = 0 1 as many pairs of white socks = 2 socksThe statement " 6 times as many pairs of blue socks" is equivalent to no socks, since we have no blue socks, hence 6*0 = 0
Let us find the total socks
= 8+0+2
= 10 socks

18. $5890
19. Mitsubishi Mirage
Step-by-step explanation:
The depreciated value can be found using an exponential relation. The decay rate here is given as 12.5%. The exponential function will have the form ...
y = a·b^x . . . . . a = initial value, b = decay factor = 1 - decay rate
__
18.The above equation will have a=15,000, representing the initial value of the car. It will have b=(1-0.125) = 0.875, the decay factor for the car's value. In the 7 years between your 18th and 25th birthdays, the car will have declined in value to ...
y = $15000·0.875^7 ≈ $5890.44
When you turn 25, the car will be worth about $5890.
__
19.We found three cars with a price under $15,000:
Nissan VersaChevrolet SparkMitsubishi MirageOf these, the Mirage gets the best mileage and has the most cargo space. (It also has the smallest engine.) The Spark has a continuously-variable transmission, not a 5-speed manual, so will be somewhat easier to drive. Its mileage is almost as good, but its range is about 10% less than that of the Mirage or Versa.
(Your curriculum may offer different choices. We cannot tell.)
Perhaps you got a Mitsubishi Mirage.

The thickness of the pile of books measured by Juan and the information in the line plot is 5.
What is the thickness of the pile of books?Based on the information in the line plot, the thinnest book has a thickess of 1 1/4 and the thickest book has a thickess of 2 1/2.
The thickness of the pile of books = (1 1/4 x 2) + 21/2
