Answer:
1.13
2.67
Step-by-step explanation:
Accordin to the graph we can say Water in liters is y and Flour in liters is x. We can determine the slop of the graph and the y-intercept when x=0. Let m be the slope of the graph and c is the y-intercept. The equation of the line is:
The slope is define as:
m=(y2-y1)/(x2-x1)
We can determine the slope by using any two points on the line. Lets use point 1 as (1,0.25) and point 2 as (3,1):
Therefore the equation of the line is:
We see from the graph that the line intercepts through point (0,0) therefore the equation is y=0.375x with a y-intercept of 0.
We can calculate the number of liters of flour per water at any point, let x=3
We can calculate the number of liters of water per flourat any point, let y=1

We first find the z-score associated with the level of confidence. For 95% confidence:
Convert 95% to a decimal: 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2 (this is the area in the tails): 0.05/2 = 0.025
Subtract from 1 (we don't want the tails, we want the area in the middle): 1-0.025 = 0.975
Using a z-table (http://www.z-table.com) we find the z-score for this is 1.96. We now use the formula
For a 98% confidence level:
Convert 98% to a decimal: 0.98
Subtract from 1: 1 - 0.98 = 0.02
Divide by 2: 0.02/2 = 0.01
Subtract from 1: 1 - 0.01 = 0.99
Using the z-table we see the closest number to this is for the z-score 2.33:

"B) No, because opposite sides are not parallel" is the correct answer
Step-by-step explanation:
As given sides of quadrilateral:
The opposite sides will be:
WX and YZ
XY and WZ
The quadrilateral is said to be a parallelogram if its opposite sides are parallel.
As we are also given slopes of lines also, the slope of opposite sides should be equal if the quadrilateral is a parallelogram
So,
As the slopes of opposites sides are not same, which means the opposite sides are not parallel so the given quadrilateral cannot be a parallelogram
Hence,
"B) No, because opposite sides are not parallel" is the correct answer
