Hey there
I 've already answered this question twice
by mistake.Kindly check.
Answer:
4π ≈ 12.5663706144
Step-by-step explanation:
The circumference of a circle is 2πr, or 2*pi*radius
Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:
4÷2=<u>2 inches</u> (radius length)
Now that we have the radius, let us <u>substitute</u> to find the circumference:
2πr=
2π2=
4π≈
<u>12.5663706144</u>
<u></u>

The equivalent expression without parenthesis that can be used to determine the total number of flowers the florist used is 4c + 36
<h3>How to find equivalent expression?</h3>
The equivalent expression without parenthesis that can be used to determine the total number of flowers the florist used.
total number of flower the florist used for the bouquet = 4(c + 9)
Therefore,
total number of flower the florist used for the bouquet = 4c + 36

What sample size is needed so that the length of the interval is $60 with 95% confidence? We Assume: σ = $150.
Showing Work:
n ======> is the sample size we want to find:
N = ( z a/2^σ / E )^2
= ( 1.96 * 150 / 30 )^2 (margin of error is 1.96 times the standard error):
Answer: =======> 96.04 ≈ 97
