Step-by-step explanation:
This question is essentially asking what the greatest common factor of 72 and 90 is. The prime factorization of 72 is:
![2^3\cdot 3^2](https://tex.z-dn.net/?f=2%5E3%5Ccdot%203%5E2)
For 90:
![2\cdot 5\cdot 3^2](https://tex.z-dn.net/?f=2%5Ccdot%205%5Ccdot%203%5E2)
Therefore, the greatest common factor is
. Hope this helps!
Answer:
Step-by-step explanation:
Assume that f(x) = 0 for x outside the interval [4,7]. We will use the following
![Var(X) = E[X^2]- (E[X])^2](https://tex.z-dn.net/?f=Var%28X%29%20%3D%20E%5BX%5E2%5D-%20%28E%5BX%5D%29%5E2)
Standard deviation = ![\sqrt[]{Var(X)}](https://tex.z-dn.net/?f=%20%5Csqrt%5B%5D%7BVar%28X%29%7D)
Mean =
Then,
![E[X] = \int_{4}^{7}\frac{1}{3}dx = \frac{7^2-4^2}{2\cdot 3} = \frac{11}{2}](https://tex.z-dn.net/?f=E%5BX%5D%20%3D%20%5Cint_%7B4%7D%5E%7B7%7D%5Cfrac%7B1%7D%7B3%7Ddx%20%3D%20%5Cfrac%7B7%5E2-4%5E2%7D%7B2%5Ccdot%203%7D%20%3D%20%5Cfrac%7B11%7D%7B2%7D)
![E[X^2] = \int_{4}^{7}\frac{x^2}{3}dx = \frac{7^3-4^3}{3\cdot 3} = 31](https://tex.z-dn.net/?f=E%5BX%5E2%5D%20%3D%20%5Cint_%7B4%7D%5E%7B7%7D%5Cfrac%7Bx%5E2%7D%7B3%7Ddx%20%3D%20%5Cfrac%7B7%5E3-4%5E3%7D%7B3%5Ccdot%203%7D%20%3D%2031)
Then, ![Var(x) = 31-(\frac{11}{2})^2 = \frac{3}{4}](https://tex.z-dn.net/?f=Var%28x%29%20%3D%2031-%28%5Cfrac%7B11%7D%7B2%7D%29%5E2%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
Then the standard deviation is ![\frac{\sqrt[]{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B%5D%7B3%7D%7D%7B2%7D)
Answer:
$270,000
Step-by-step explanation:
1. 3/10 = 30% and 30% of 3,000,000 is equal to 900,000
2. 900,000 divided by 1,000 is 90,000
Then, to calculate the dollar amount we do:
3. 90,000 x 3.00 = 270,000
In step 1, we found 3/10 of her total streams. In step 2, we found how many streams were monetized. And, in step 3 we found the amount of money she made off of those streams.
