Employees at a large office building took a survey. The results show that those who began work earlier tended to drink less tea. Which statement is most likely true?
Answer:
B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.
In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.

Elena made $1,350 in 18 days. Let c represent the amount of money she made each day. If Elena made the amount of money each day, how much did she make in 1 day? Write an division equation.
The rate of money earned per day will be $75 per day.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
Elena made $1,350 in 18 days.
Earning per day = ($1350/18) = $75 per day.
Hence "The rate of money earned per day will be $75 per day".

Given quadrilateral EFGH at e(-4,7) f(8,4) G(t,-5) and h(-7,-1) using coordinate geometry prove EFGH is a rectangle
The above question was not properly written.
Complete Question
Given quadrilateral EFGH with vertices at E(-4,8), F(8,4), G(5,-5) and H(-7,-1), prove using coordinate geometry that EFGH is a rectangle.
Answer:
Quadrilateral EFGH is a rectangle.l because:
EF = GH and FG = EH
Step-by-step explanation:
The formula for coordinate geometry is given as :
√(x2 - x1)² + (y2 - y1)² when we have coordinates: (x1, y1) and (x2 , y2)
For the quadrilateral EFGH with given coordinates above to be a rectangle,
EF = GH
FG = EH
Hence:
For side EF
E(-4,8), F(8,4)
= √(8 - (-4))² + (4 - 8)²
= √12² + -4²
= √144 + 16
= √160 units
For side FG
F(8,4), G(5,-5)
=√(5 - 8)² + (-5 - 4)²
= √-3² + -9²
= √9 + 81
= √90 units
For Side GH
G(5,-5) , H(-7,-1)
= √(-7 - 5)² + (-1 - (-5))²
= √-12² + 4²
= √144 + 16
= √160 units
For side EH
E(-4,8), H(-7,-1)
= √(-7 -(-4))² +(-1 - 8)²
= √-3² + -9²
= √9 + 81
= √90 units
From the above calculation, we can see that truly,
EF = GH
FG = EH
Therefore, quadrilateral EFGH is a rectangle.

Answer:
m∠1 = 30°
Step-by-step explanation:
Properties of a rhombus,
1). Sum of adjacent angles is 180°.
2). Diagonals bisects the angles of a rhombus
By property - (1)
m∠M + m∠N = 180°
120° + m∠N = 180°
m∠N = 180 - 120
= 60°
By property - (2)
Diagonal PM will bisect the angle M.
m∠1 = m∠2
m∠1 = [tex]\frac{1}{2}(\angle N)[/tex]
= [tex]\frac{1}{2}(60)[/tex]
= 30°

In New York, state sales tax rates vary by county. In Allegany County, the sales tax rate is 8 1/2%. At a local store a book costs $12.99 and a video game costs $39.99. Rounded to the nearest cent, how much more is the tax on the video game than the tax on the book?
Answer:
12.99/100 X 108.5 = 14.09
39.99/100 X 108.5 = 43.39
43.39 - 14.09 = 29.3
difference = $29.30

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?
2m-3 =2+1m
Answer:
m=5
Step-by-step explanation:
There are no fractions involved to eliminate.
2m-3=2+1m
m=5
Based on the given scenario, the solution to the equation 2m - 3 = 2 + 1m is m = 5.
What is fraction?Fractions are a way of representing parts of a whole. They are written in the form of a numerator and a denominator, separated by a horizontal line.
For example, the fraction 3/4 represents three parts of a whole that is divided into four equal parts.
To eliminate the fractions in the equation 2m - 3 = 2 + 1m, we can multiply both sides of the equation by the least common multiple (LCM) of the denominators of the fractions.
However, in this equation, there are no fractions, so we don't need to multiply by anything to eliminate them. The equation is already in a form that can be solved using basic algebraic techniques.
To solve for m, we can start by moving all the m terms to one side of the equation and all the constant terms to the other side:
2m - 1m = 2 + 3
Simplifying, we get:
m = 5
Therefore, the solution to the equation 2m - 3 = 2 + 1m is m = 5.
