Answer:
1st angle = X
2nd angle = X + 7
3rd angle = X + 18
Then (sum. them): 3X + 25 = 180 ==> X = 51.67 degree
Therefore,
1st angle = 51.67 degree
2nd angle = 58.67 degree
3rd angle = 69.67 degree
Is 5 because the factor of 15 can not be other number except 5
Answer: 1/20
To find P(Q and R), you have to multiply P(Q) by P(R) to get the probability that both events will occur. P(Q) = 1/8, and P(R) = 2/5, so when multiplied together, you get 2/40. This simplifies to 1/20, meaning P(Q and R) = 1/20.
Answer: 92
Step-by-step explanation:
Keep in mind the definition of a function. For 2 points, (x,y) and (x,z) it is a function only if y = z.
Because you have the points {0.3,0.6} and {0.3,0.7}, for it to be a function, 0.6 would have to equal 0.7. Since this is clearly false, it is not a function.
