Answer:
115.3 hertz
Step-by-step explanation:
For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.
For the first interval:

For the second interval:

48/100 (simplified: 6/25) - Fraction form
.48 - decimal form
48% - percent form
Data:
Formula: diameter = 2*radius
Formula: (<span>Circle length)
</span>

<span>
Solving: </span><span>Using the data
</span>diameter = 2*radius
20 = 2*r
2r = 20


<span>Now, replace in the circumference length formula
</span>



Answer:
<span>
The exact circumference of the circle is </span>
Answer:
it would be 3 yards because it went 2° to the right
I think It would be -4-(-8)/2-(-9)=-4+8/2+9=4/11 is the equation by using y2-y1/x2-X1
Sorry If I'm wrong.
