Step-by-step explanation:
If 5 was the radius, do 3.14 (5)^2 same thing as= 3.14 times 25
Which equals 78.5 (I rounded it also)
Let me know if it was correct!
Is it addition or subtraction in between the numbers
Answer:
Step-by-step explanation:
Given expression/polynomial :
Let's evaluate.
We can re-write the polynomial as
Further
Hence, the expression is equivalent to last Choice, (6x)²-(5)².

There are four sides to a rectangle. Two "widths" and two "lengths"
8(2) = 16 width.
12(2) = 24 length.
16 + 24 = 40.
The perimeter of this rectangle is 40 feet.
Answer:
Option B.
Step-by-step explanation:
As we know that
Margin of error = Z * standard error
Here , the only way to decrease the value of margin of error is to decrease either the value of z or value of standard error as both are directly proportional to margin of error.
Z-value can be decreased by using lower confidence intervals. Standard error can be decreased by increasing sample size (as given in option B)
The answer is option B as it is using sample size of 50 instead of 35 thus decreasing standard error and ultimately decreasing margin of error.
