Answer:
No it cannot be concluded.
Step-by-step explanation:
The probability of getting the disease in the first attempt is 50%
The probability of getting the disease in the second attempt is 50%
Thus the probability of getting the disease in either of the turns is 50%+50%=100% (which may seem to be true)
BUT
The probability of not getting the disease in the first attempt is 50%
The probability of not getting the disease in the second attempt is 50%
Thus the probability of not getting the disease in either of the turns is 50%+50%=100% (which is also true for this case)
Thus the probability of getting the disease in either of the 2 contacts is still 50%
In order to find a fraction, We know that a percentage is out of a 100. This means we can now place our fraction as:
38/100
In order to find the actual fraction, we will want to simplify. Lets find our least common factor and work down from there. Since we know that 2 can go into both of them, lets reduce by 2.
This means our fraction will now look like:
19/50
Since 19 is a prime number and cannot be divided by anything but 1 and itself, we know that this is our simplified form.
This means:
19/50 is the fraction equivalent to 38%.
a. The constant of proportionality is k = 2
b. If Micah saves $150, his parents will give him $300
<h2>
Explanation:</h2>
<h3>PART A.</h3>
From mathematics, we know that
varies directly as
or
is directly proportional to
if and only if:
for some nonzero constant
.
Here we know some facts:
- For every $5 that Micah saves, his parents give him $10.
In other words:
Let y be the money his parents give him.
Let x be the money that Micah saves.
![We \ know \ that: \\ y=kx \\ \\ \\ Solving \ for \ k: \\ \\ k=\frac{y}{x} \\ \\ k=\frac{10}{5} \\ \\ \boxed{k=2}](https://tex.z-dn.net/?f=We%20%5C%20know%20%5C%20that%3A%20%5C%5C%20y%3Dkx%20%5C%5C%20%5C%5C%20%5C%5C%20Solving%20%5C%20for%20%5C%20k%3A%20%5C%5C%20%5C%5C%20k%3D%5Cfrac%7By%7D%7Bx%7D%20%5C%5C%20%5C%5C%20k%3D%5Cfrac%7B10%7D%7B5%7D%20%5C%5C%20%5C%5C%20%5Cboxed%7Bk%3D2%7D)
So,<em> the constant of proportionality is k = 2</em>
<h3>
PART B.</h3>
In this case, we know that Micah saves $150. So we need to find the amount of his parents will give him. So what we know here is the value of x, because x represents the amount of money Micah saves. Therefore, by knowing x and k, we can calculate the value of y, which is the amount of money his parents will give him. Hence:
![For \ x=150 \ and \ k=2: \\ \\ y=2(150) \\ \\ \boxed{y=300}](https://tex.z-dn.net/?f=For%20%5C%20x%3D150%20%5C%20and%20%5C%20k%3D2%3A%20%5C%5C%20%5C%5C%20y%3D2%28150%29%20%5C%5C%20%5C%5C%20%5Cboxed%7By%3D300%7D)
Finally, <em>if Micah saves $150, his parents will give him 300$</em>
