Answer:
(a) One count is only 7, and the guidelines for using the large-sample method call for all counts to be at least 10.
Step-by-step explanation:
Attached is the solution to b and c
The question is an illustration of a division model.
The boxes will be completed with: 1650, 231, 50 and 7
The expression is represented as:
Express 1881 as 1650 + 231.
Split
Evaluate each division
The above illustration means that, the boxes will be completed with the following numbers

The shortest side is 130 feet, the longest side is 260 feet and the greatest possible area is 33800 square feet
<h3>What dimensions would guarantee that the garden has the greatest possible area?</h3>
The given parameter is
Perimeter, P = 520 feet
Represent the shorter side with x and the longer side with y
One side of the garden is bordered by a river:
So the perimeter is:
P = 2x + y
Substitute P = 520
2x + y = 520
Make y the subject
y = 520 - 2x
The area is
A = xy
Substitute y = 520 - 2x in A = xy
A = x(520 - 2x)
Expand
A = 520x - 2x^2
Differentiate
A' = 520 - 4x
Set to 0
520 - 4x = 0
Rewrite as:
4x= 520
Divide by 4
x= 130
Substitute x= 130 in y = 520 - 2x
y = 520 - 2 *130
Evaluate
y = 260
The area is then calculated as:
A = xy
This gives
A = 130 * 260
Evaluate
A = 33800
Hence, the shortest side is 130 feet, the longest side is 260 feet and the greatest possible area is 33800 square feet

are you going to show a picture??? its impossible to answer otherwize
Well, basically there are
acute angle, right angle, obtuse angle ..
and also we use concurrent angles, corresponding angles, alternate angles, vertically opposite angles,..
..hope it helped a bit
