Answer:
1. Dots
2.Blank
3. Stripes
4. Stars
Step-by-step explanation:
Well the total is 30 and we just have to see the fraction of each time in landed on a specific part of the spinner. So first the probability of landing on dots is 6/30 = 1/5
Then the experimental probability of getting a blank is 8/30 = 4/15
Continuing in the same manner getting stripes would have a chance of 12/30 which is 2/5
Finally I'm gonna let you think about how I got the last one and why I did what I did :)
Mrs.Lombardo.<span>if you do the math out, 4/5 and 2/3 give you an LCD (Least Common Denominator) of 15, so this means 4/5 = 12/15, and 2/3 = 10/15. 4/5 is greater than 2/3. </span>
Answer:
Option 2) The expression is equal to 1 over 12 factors of r
Option 4) Multiplying the exponents will create an equivalent expression.
Step-by-step explanation:
We are given the following in the question:
![(r^{-4})^3](https://tex.z-dn.net/?f=%28r%5E%7B-4%7D%29%5E3)
Properties of exponent:
![(x^m)^n = x^{mn}\\\\x^{-a} = \dfrac{1}{x^a}](https://tex.z-dn.net/?f=%28x%5Em%29%5En%20%3D%20x%5E%7Bmn%7D%5C%5C%5C%5Cx%5E%7B-a%7D%20%3D%20%5Cdfrac%7B1%7D%7Bx%5Ea%7D)
Thus, we can simplify the given expression as:
![(r^{-4})^3\\=r^{-12}\\\\=\dfrac{1}{r^{12}}](https://tex.z-dn.net/?f=%28r%5E%7B-4%7D%29%5E3%5C%5C%3Dr%5E%7B-12%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7Br%5E%7B12%7D%7D)
Thus, the correct answer is:
Option 2) The expression is equal to 1 over 12 factors of r
Option 4) Multiplying the exponents will create an equivalent expression.
