Answer:
Sampling bias
Step-by-step explanation:
Bias refers a prominent problem in statistical analysis whereby one or more analytical factor are favored than the other during an analysis which should be made random. The problem. With Graham's dissertation study is the fact that he failed to randomlyvplace his subjects or observation in the study groups, favoring a particular group with non random subset. When randomization is ejected or missing from an analysis or study, it becomes less and less representative. Here, allotting early Arrivals Into the treatment group has introduced a sampling bias as those who came later, this will also leads to less reproducibility of experiment.
How many grams are in 1 pound (on Earth)? Round to the nearest tenth.
Answer:
453.6, or 453.59237
Step-by-step explanation:
Answer:
28.35 grams is equivilent to 1/16 lb., which is 1 oz. So, 28.35 x 16= 453.6
Step-by-step explanation:
First you must convert ounces to grams
Then, you must convert the ounces to pounds
You do this by knowing that 1 oz is 1/16 of a lb
Knowing that 28.35 grams are in 1 oz
You then multiply the 28.35 grams by the 16 oz
Which gives you 453.6 0r 453.60 grams in 1 lb

Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = [tex]\frac{0-(-2)}{4-0}[/tex] = [tex]\frac{0+2}{4}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

x^2 – 2x – 54 = 0
I need it in completing the square form
Completing the Square:
x^2 - 2x = 54
x^2 - 2x + 1 = 54 + 1
(x-1)^2 = 55
x - 1 = ±[tex]\sqrt{55\\}[/tex]
x = 1 ± [tex]\sqrt{55}[/tex]

A basket is filled with apples. There are 10 green apples, which is 25% of the total number of apples in the basket. Which equation can be used to determine x, the total number of apples in the basket
Answer:
x = 40 or x = 4(10)
Step-by-step explanation:
If x is the total number of apples in the basket then the equation would be
x = 40 or x = 4(10). (Double check to make sure I'm correct)
150 into the ratio 4:11
9514 1404 393
Answer:
40 : 110
Step-by-step explanation:
There are a number of ways you can go at this. One of my favorite is to consider the value of a "ratio unit." Here, a total of 4+11 = 15 "ratio units" represent the total to be divided: 150. So the value of each one is ...
150/15 = 10
Then the division is ...
4 : 11 = 10·4 : 10·11 = 40 : 110
_____
Alternate solution
Let x represent the larger share. Then the ratio is ...
(150 -x) : x = 4 : 11
Cross-multiplying gives ...
11(150 -x) = 4x
1650 = 15x . . . . . add 11x, simplify
110 = x . . . . . . . . . divide by 15; the larger share
150-x = 150-110 = 40 . . . . . . the smaller share
The division is 40 : 110.

On Saturday, Mark sold 2 7/8 gallons of lemonade.
On the same day, Regan sold 2/3 as much lemonade as Mark.
How much lemonade, in gallons, did Regan sell?
Answer:
Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade
Step-by-step explanation:
Operations with Fractions
Mark sold [tex]2\frac{7}{8}[/tex] gallons of lemonade.
Regan sold [tex]\frac{2}{3}[/tex] as much lemonade as Mark
We can find the portion of lemonade Regan sold by multiplying both fractions. But first, we must convert to improper fraction:
[tex]2\frac{7}{8}=2+\frac{7}{8}=\frac{23}{8}[/tex]
Now we multiply:
[tex]\frac{23}{8}\cdot \frac{2}{3}=\frac{46}{24}=\frac{23}{12}[/tex]
Regan sold [tex]\mathbf{\frac{23}{12}}[/tex] gallons of lemonade
