Answer:
50 times.
Step-by-step explanation:
When the 2 number cubes are rolled once:
The possible outcomes for a total of 7 are:
1 and 6
6 and 1
2 and 5
5 and 2
3 and 4
4 and 3
= 6 outcomes.
The total of all possible outcomes = 6 * 6 = 36.
So Prob( total of 7 in one throw of teh 2 cubes) = 6/36 = 1/6.
For 300 throws you would expect the total of 7 to occur
1/6 * 300 = 50.
A coordinate plane have good day sir!
Answer:
I think cubic polynomial cause degree is 3
Question:
What is the value of c in the equation below?
A. -4 B. -2 C. 1/64 D. 1/4
Answer:
![c = \frac{1}{4}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
Given
![2^{-4}*2^2 = a^b = c](https://tex.z-dn.net/?f=2%5E%7B-4%7D%2A2%5E2%20%3D%20a%5Eb%20%3D%20c)
Required
Find c
The equation can be rewritten as:
![c = 2^{-4}*2^2](https://tex.z-dn.net/?f=c%20%3D%202%5E%7B-4%7D%2A2%5E2)
![c = a^b](https://tex.z-dn.net/?f=c%20%3D%20a%5Eb)
Solving: ![c = 2^{-4}*2^2](https://tex.z-dn.net/?f=c%20%3D%202%5E%7B-4%7D%2A2%5E2)
Apply law of indices
![c = 2^{-4+2}](https://tex.z-dn.net/?f=c%20%3D%202%5E%7B-4%2B2%7D)
![c = 2^{-2}](https://tex.z-dn.net/?f=c%20%3D%202%5E%7B-2%7D)
Apply law of indices
![c = \frac{1}{2^2}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7B1%7D%7B2%5E2%7D)
![c = \frac{1}{4}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
