PLEASE HELP ALGABRA 1 !

Mathematics
1 answer:
Yuki888 [10]3 years ago
8 0

Answer:

D

Step-by-step explanation:

The ratio of the first 3 is 2:4:8

And 50,000:100,000:200,000 is equivalent to that.

You're multiplying by 2

2*2=4*2=8 and

50,000*2=100,000*2=200,000

And if you add the first 3 and the 4th one's profit you get 400,000

50,000+100,000+200,000+50,000= 400,000

What is the z-score for a patient who takes 7 days to recover? (choose the closest possibility.)
Kisachek [45]

Based on the time it took the patient to recover and the mean and standard deviation, the z-score is 1.5.

<h3>What is the z-score?</h3>

The z-score for this patient who takes 7 days to recover can be found as:

= (Time taken to recover - Mean) / Standard deviation

Solving for the z-score gives:

= (7 - 5.2) / 1.2

= 1.8 / 1.2

= 1.5

The first part of the question is:

The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 1.2 days.
