Answer:
x = 4 + sqrt 5
x = 4 - sqrt 5
Step-by-step explanation:
(X-4)^2 = 5
X - 4 = + - sqrt 5
X = 4 + sqrt 5 and
X = 4 - sqrt 5
Steps:
1. Input the data in Excel
2. Find maximum and minimum values (2 and 87 respectively)
3. Calculate the range, that is,
Range = (maximum -minimum)/Number of intervals. For 10 intervals;
Range = (87-2)/10 = 8.5
4. Generate the Bin. That is,
From minimum and adding range until the maximum value.
Using Histogram tool in Excel, the histogram was generated as shown in the figures attached.
Answer:
units.
Step-by-step explanation:
We have been given that the bottom of a vase is a square. Each side measures y+11 units. The square has a perimeter of 55 units.
Since we know that all sides of square are of equal measure and the perimeter of a square is 4 times the length of each side.
Upon substituting our given values in above formula we will get,
Upon distributing 4 we will get,
Upon subtracting 44 from both sides of our equation we will get,
Upon dividing both sides of our equation by 4 we will get,
Therefore, the value of y is 2.75 units.
9.25 per 2.8 pound
9.25/2.8=3.303/1=$3.30 per pound
