Ответ:
0.8133.
Step-by-step explanation:
We have been given that the ages of smartphone users approximately follow a normal distribution with approximate mean and standard deviation of 39.9 years and 9.1 years, respectively.
First of all, we will use z-score formula to find z-score of 48.
, where,
= z-score,
= Sample score,
= Mean,
= Standard deviation.
Substitute the given values:
Now, we will need to find the probability of z-score less than or equal to 0.89 as:
Using normal distribution table, we will get:
Therefore, the probability that a random smartphone user is at most 48 years old would be 0.8133.

1. The initial value of the furniture is $10,000
2. $2,000
3. [0,10]
Step-by-step explanation:
1. the initial value is the very begining, so along the y axis where x=0
2. Original: $10,000 during the first year its worth $8,000, subtract 8,000 from 10,000 which equals 2,000
3. 0=2009, 10=2019
