The randomly selected subject is given bone density test which are normally distributed with mean =0 and standard deviation =1. It means bone density test score is standard normal variable.
The probability that a given score is less than 2.23
P(z < 2.23)
Using z score table to find probability below z=2.23
P(z < 2.23) = 0.9871
The probability that a given score is less than 2.23 is 0.9871
Answer:
117.2
Step-by-step explanation:
Rounding a number to the nearest tenth:
A number rounded to the nearest tenth will have one decimal place.
To do this, we look at the second decimal digit.
If it is less than 5, the first decimal digit is kept.
Otherwise, one is added to the first decimal digit.
In this question:
117.22666
The second decimal digit is 2, which means that we keep the first decimal digit which is also 2.
So, the number rounded to the nearest tenth is 117.2.
One pack of strings is $14. This is because 72-16=56. I subtracted the 16 because it is how much the book cost, so it does not have anything to do with the amount one pack of strings cost. Then, I divided 56 by 4 which equals 14. I divided 56 by 4 because the question is how much one pack is, and Noah and Kate bought a total of 4 packs. This proves that one pack of strings costs $14.
Hope this helps you!
