Answer:
x = 57.6
Step-by-step explanation:
The length of the segment on the right is 30/25 = 1.2 times the length of the segment on the left.
x = 1.2 × 48 = 57.6
_____
<em>Additional comment</em>
Parallel lines cut transversals proportionally. That is why 30/25 = x/48.
300/15 = d
I hope this helps!
Every confidence interval has associated z value. As confidence interval increases so do the z value associated with it.
The confidence interval can be calculated using following formula:

Where

is the mean value, z is the associated z value, s is the standard deviation and n is the number of samples.
We know that standard deviation is simply a square root of variance:

The confidence interval of 95% has associated z value of <span>1.960.
