What type of sampling method is margo using?.
It is found that Margo are going to be using sampling.
• sampling in statistics may be a a part of the sampling technique within which each sample has an equal probability of being chosen. In other words, a sample chosen randomly is an unbiased representation of the entire population.
Sample strategies is also classified as :
1) Convenient: The sample that is taken from a pool that is readily accessible.
2) Random : When all options are into a hat and draw a number of team
3) Systematic : Every kth element
4) Cluster : once we divide population into groups called clusters, and every element of cluster is surveyed.
5) Stratified : In stratified also divides the population into groups, However just some of the weather of the group are surveyed. per the question Marbles are taken from the bag, and after they're taken they're again placed back within the bag so it depicts sampling.

Inequality expressionsInequalities are expressions that are not equated by an equal sign. Given the expression below:
3(8 – 4x) < 6(x – 5)
Expand to have:
3(8) - 3(4x) < 6x - 6(5)

make b the subject of p=1/2ab^2+c
The variable b as the subject of the formula is b = √2(p -c)/a
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to make b the subject of the equation?The equation is given as
p = 1/2ab^2 + c
Subtract c from both sides of the equation
So, we have
1/2ab^2 = p - c
Multiply through by 2
ab^2 = 2(p -c)
Divide by a
b^2 = 2(p -c)/a
Take the square root of both sides
b = √2(p -c)/a
Hence, b as the subject of the formula is b = √2(p -c)/a

label each quantity as an exact or inexact number. the four bicycles in the family have been ridden for a total of 250 mi. a child fell and had a 4-cm laceration that required 12 stitches.
Both statements can be included in the exact numbers category.
Maple provides two kinds of numbers: exact and inexact. If you do arithmetic with exact numbers (and they aren't too large) the answer that you get back is exactly right. If you do arithmetic with inexact numbers (and they aren't too large or too small) the answer may have a small amount of roundoff error. Although we'll treat this distinction at length in future lessons, it is convenient to take a preliminary look right now.
consider the four bicycles in the family have been ridden for a total of 250 mi.
The above statement can be categorized into exact numbers as 4 and 250 are countable.

the density of a certain material is such that it weighs 3 grams per fluid ounce of volume. express this density in ounces per liter. round your answer to the nearest hundredth.
The density in ounces per liter is 3.57826 rounding off = 3.58
Density of a substance can be defined as a relationship between the mass and the volume of that substance.
[tex]Density=\frac{Mass}{Volume}[/tex]
For Example if a metal have a mass 0f 7gm and volume as [tex]5cm^{3}[/tex]
[tex]Density=\frac{7}{5} = 1.4g/cm^{3}[/tex]
we know that 1 gram/fluid ounce of volume = 1.19275 ounces/liter
1 gm/fluid ounce =1.19275 ounces/liter
3 gm/fluid ounce = 3*1.19275 ounces/liter
So 3 gm/fluid ounce = 3.57826 ounces/liter

Acme widgets had an order to process 250 widgets. The first unit required 200 minutes to assemble. Before starting, the company estimated the amount of time it would require to assemble all 250 widgets if they learned at an 85% rate. After assembling all 250 widgets, acme realized they had learned at an 80% rate. How much time less than their estimate did acme take? you should be able to compute the answer within plus or minus 2 hours.
91.2 hours less was taken to assemble the parts of the widgets by estimation.
Firstly, we will find out the range:
Using the cumulative unit table to determine the range, we get that-
Range = 88.83 - 61.47
Range = 27.36
Secondly, we will calculate the minutes requires to assemble the widgets.
Number of minutes = 27.36 × 200 minutes
Number of minutes = 5472minutes
Now, we have to calculate how much time less than their estimate did acme take:
Time = 5472 / 60
Time = 91.2
Therefore, we get that, 91.2 hours less was taken to assemble the parts of the widgets by estimation.

g) Cents 102.9 convert to Dollars 1.029
h) Cents 98.9 convert to Dollars 0.989
i) $56.60
j) $54.40
Step-by-step explanation:
e) is correct. The discount is 4¢ per litre
f) It should be cents, not dollars
g) Without a voucher, the cost of fuel is 102.9¢ = $102.9/100= $1.029
h) Since the discount is 4¢ per litre, the price of fuel comes down froom 102.9 - 4 = 98.9¢ = 98.9/100 $ = $0.989
i) 55L at undiscounted price = 55 x $1.029 = $56.595 rounded up to $56.60
j) With a voucher, there is a discounted price of $0.989 per litre. So for 55L, discounted price with voucher = 55 x 0.989 = $54.395 = $54.40 rounded to the nearest cent

Find the measure of the longest angle
The largest angle of the given triangle is 105 degrees. If its measure of other two angles are (6x +17) degrees and (5x + 14) degrees.
According to the given question.
We have, the measure of the angles of a triangle are 105 degrees,
(6x +17) degrees, (5x + 14) degrees.
As we know that the sum of the angles of a triangle is always 180 degrees.
Therefore, we can say that
105 + (6x +17) + (5x + 14) = 180
⇒ 105 + 6x + 17 + 5x + 14 = 180
⇒ 136 + 11x = 180 (adding the like terms)
⇒ 11x = 180 -136
⇒ 11x = 44
⇒ x = 44/11
⇒ x = 4 degrees.
So, (6x +17) degrees = 6(4) + 17 = 24 + 17 = 41 degrees
and, (5x + 14) degrees = 5(4) + 14 = 20 + 14 = 34 degrees
Hence, the largest angle of the given triangle is 105 degrees. If its measure of other two angles are (6x +17) degrees and (5x + 14) degrees.
