Answer:
√41
Step-by-step explanation:
Use a² + b² = c²
a = 4
b = 5
4² + 5² = c²
4² = 16
5² = 25
16 + 25 = c²
41 = c²
You need to get ² away from c, so square root both sides.
√41 = √c²
√41 = c
√41 is in its simplest form, so it is left as √41.
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: 6.71 × 10^6 people
Step-by-step explanation:
Given that the population of New Zealand was approximately 4.43million people. In the same year, the population of Belgium was approximately 11.14 million people.
The difference in number of population will be
(11.14 - 4.43) millions
= 6.71 millions people
Expressing the answer by using scientific notation will be
6.71 × 10^6 people.
Therefore, 6.71 × 10^6 people live in Belgium than in New Zealand
