36% chance of the person being less than 20 years okd
Answer:
Following are the solution to the given question:
Step-by-step explanation:
Confidence Interval for both the percentage of all x-ray machines
p = the machinery's share is not working:

Lower
Confidence interval = p - error margin
Upper
Confidence Interval = p + error margin
So,
Confidence Interval 
The red graph is the result of a vertical translation, 4 units down, of the black graph.
This means that, whenever the black graph associates

The red graph must associate 4 less to the same input:

So, the equation for the red graph is

or, equivalently,

(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
Ok so there are 1,000 ml in every liter so
76000 ml= L which is a thousand ml
76000/1000
=76 L
