Answer:
A = 31.875 inches squared
Step-by-step explanation:
Area of a parallelogram is bh
b = 12 and 3/4 is just 12.75 inches
h = 2 and 1/2 is just 2.50 inches
Multiply these together and you get the area,
A = (12.75)(2.50) = 31.875 inches squared
A ton is 2000 lbs. If a polar bear is 1600 lbs then the fractional part of a ton would be...
1600/2000 which will reduce to
16/20 = 4/5
Answer:
The minimum sample size required to create the specified confidence interval is 2229.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
What is the minimum sample size required to create the specified confidence interval
This is n when 
Rounding up
The minimum sample size required to create the specified confidence interval is 2229.
Step-by-step explanation:
Pick two points on the line and determine their coordinates
Select one to be (x1, y1) and the other to be (x2, y2)
Finally use the slope intersect equation to calculate the slope:
<em>Formula-</em><em> </em>
<em>y = mx + b </em>
<em></em>
