If you already know that you have . . .
1$ after week 1
2$ after week 2
4$ after week 3
8$ after week 4
. . . You can then tell that every week the money you save doubles (times 2)
So to continue . . . .
16$ after week 5
32$ after week 6
64$ after week 7
128$ after week 8
256$ after week 9
512$ after week 10
You will then know that after ten weeks u will have 512$ which is answer choice D.
Hope this helps! :)
Answer:
37.27% probability that he or she will have a heart attack.
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
![P(B|A) = \frac{P(B)*P(A|B)}{P(A)}](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7BP%28B%29%2AP%28A%7CB%29%7D%7BP%28A%29%7D)
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Periodontal disease
Event B: Heart attack
Researchers discovered that 82% of people who have suffered a heart attack had periodontal disease, an inflammation of the gums.
This means that ![P(A|B) = 0.82](https://tex.z-dn.net/?f=P%28A%7CB%29%20%3D%200.82)
Only 33% of healthy people have this disease.
This means that ![P(A) = 0.33](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.33)
Suppose that in a certain community heart attacks are quite rare, occurring with only 15% probability.
This means that ![P(B) = 0.15](https://tex.z-dn.net/?f=P%28B%29%20%3D%200.15)
If someone has periodontal disease, what is the probability that he or she will have a heart attack
![P(B|A) = \frac{0.15*0.82}{0.33} = 0.3727](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7B0.15%2A0.82%7D%7B0.33%7D%20%3D%200.3727)
37.27% probability that he or she will have a heart attack.
Wouldnt be 36.7 or no i underlined 7 because it never ends

Line plots are used to display data elements using markers
The total growth, in inches, of Isabella's plant is
inches
<h3>How to determine the total growth</h3>
From the line plot, the total growth can be represented as:
![Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3](https://tex.z-dn.net/?f=Total%20%3D%20%5Cfrac%2018%20%2A%204%20%2B%20%5Cfrac%2028%20%2A%202%20%2B%20%5Cfrac%2038%20%2A%203%20%2B%20%5Cfrac%2048%20%2A%201%20%2B%20%5Cfrac%2058%20%2A%203)
Evaluate the products
![Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8](https://tex.z-dn.net/?f=Total%20%3D%20%5Cfrac%2048%2B%20%5Cfrac%2048%20%2B%20%5Cfrac%2098%20%2B%20%5Cfrac%2048%20%2B%20%5Cfrac%20%7B15%7D8)
Evaluate the sum
![Total = \frac{4+4+9+4+15}8](https://tex.z-dn.net/?f=Total%20%3D%20%5Cfrac%7B4%2B4%2B9%2B4%2B15%7D8)
Evaluate the numerator
![Total = \frac{36}8](https://tex.z-dn.net/?f=Total%20%3D%20%5Cfrac%7B36%7D8)
Evaluate the quotient
![Total = 4\frac{1}2](https://tex.z-dn.net/?f=Total%20%3D%204%5Cfrac%7B1%7D2)
Hence, the total growth, in inches, of Isabella's plant is
inches
