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
3x+8=5x-1
3x-5x=-1-8
-2x=-9
x=4,5
AM=3x4,5+8=21,5
MB=5x4,5-1=21,5
AB=AM+MB
AB=21,5+21,5=43
Your answer is +1
= -19, -18, -17, -16, -15, -14, -13, -12, -11, -10, -9 and so on…
Answer:
Where h,k represent the vertex and we got:
(5,6)
Step-by-step explanation:
We have this original function given :
And we want to find the vertex for this new function 
and we have:
And solving the square we got:
And adding similar terms we got:
Now we can complete the square like this:
The general equation is given by:
Where h,k represent the vertex and we got:
(5,6)
