Answer:
Problem 1: 1/18 (1/3 probability of greater than 4, then a 1/6 probability of landing on 2)
Problem 2: 1/3 (Chance of landing on 2 numbers out of 6)
Step-by-step explanation:
Answer:
1.4
Step-by-step explanation:
Answer:
The first one is 2, the second one is 7/8.
Step-by-step explanation:
You can do self-checking.
Answer:
1. 37 degrees, 2. 39 degrees, 3. 27 degrees
Step-by-step explanation:
You look at the total angle and subtract it by the angle that is given in the question since the two angles should add up to the whole angle of both. You should look at the number that is outside the angles and subtract it by the angle number inside then you will get the missing angles. The last one it is showing a 90 degree angle which is formed so you subtract 63 from 90.
The question is a bit ambiguous: you may mean
![\sqrt{3x+8}](https://tex.z-dn.net/?f=%5Csqrt%7B3x%2B8%7D)
or
![\sqrt{3x}+8](https://tex.z-dn.net/?f=%5Csqrt%7B3x%7D%2B8)
Anyway, in both cases, the domain of a function involving a square root is found by imposing the content of the root to be greateer than or equal to zero. So, in the first case you have
![3x+8\geq 0 \iff 3x\geq -8 \iff x\geq -\dfrac{8}{3}](https://tex.z-dn.net/?f=3x%2B8%5Cgeq%200%20%5Ciff%203x%5Cgeq%20-8%20%5Ciff%20x%5Cgeq%20-%5Cdfrac%7B8%7D%7B3%7D)
In the second case, you have
![3x\geq 0 \iff x\geq 0](https://tex.z-dn.net/?f=3x%5Cgeq%200%20%5Ciff%20x%5Cgeq%200)
