Answer:
<em><u></u></em>
Explanation:
<u>1. Determine the percent of people who developed dementia from the entire population. </u>
a)<u> From the percent of people who had depression</u>:
b) <u>From the number of people who did not have depression</u>:
c) <u>Total percent:</u>
- 2.2% + 15.3% 17.5% of all people developed dementia.
<u>2. Probability that the person suffered from depression earlier in life, if a person has developed dementia:</u>
- percent of people who developed dementia and had depression / percent of people who developed dementia = 2.2% / 17.5% = 0.126
Note, that this can be calculated using the formula for conditional probability:
Where:
- A is having suffered depression
- B is having developed dementia
- A∩B is having both suffered depression and developed dementia
- P(A∩B) = 22% ₓ 10% = 2.2% = 0.022
- P(B) = 22% × 10% + 17% × 90% = 17.5% = 0.175
- P(A/B) = P(A∩B) / P(B) = 0.022 / 0.175 = 0.126
We are given that popularity of television is inversely proportional to its cost.
let us say popularity of television is represented by "P" and cost of television by "T".
We will use a constant "k" to convert the proportionality sign to equal to (=) sign.
Thus forming the equation :
We are given that 15 customers buy a television that cost $1500.
plugging P=15 and T=1500, finding k,
k=15*1500 = 22500
Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,
P=9
So there will be 9 customers that buy a television which costs $2500.
As the number of files increases, the storage space used increases
It would be the first table. As you can see there is a pattern, every hour the temperature increases by 6 degrees. Since this pattern is throughout the whole table that is the correct answer. You could also graph the points, time on the horizontal axis and temperature on the vertical axis, it will create a straight line. (That’s the best I could explain it). Also the second table would be exponential, which is not proportional...
