On a cube, you have 6 faces, therefore you have 1 chance to get 6 and 5 chances not to get 6.
Therefore, the overall probability not to get 6 is 5/6 = 0.8333
If you roll the cube 18 times, the prediction of unsuccessful rolls will be:
18 × 0.8333 = 15
Therefore, you expect to have 15 unsuccessful rolls over 18 total rolls.
Answer:
Either (3,b) or (3,e) must be removed to form the above relation to be function.
Step-by-step explanation:
Given the relation between the elements of domain and range. we have to remove the link between two elements so that relation becomes a function.
A function is a relation in which each element in domain set maps into only one element of range set i.e one element can never have two images in range set.
Here, the element 3 in domain set maps into two element b and e in range set. Therefore, to form a function one link must be removed either
f(3)=b or f(3)=e
Hence, either (3,b) or (3,e) must be removed to form the above relation to be function.

Answer:
Step-by-step explanation:
For what mileages will company A (which has a flat rate of $111) be less than the cost for company B
Company A < Company B
111 < 75 + 0.80m
solving
111 - 75 < 75 - 75 + 0.80m
36 < 0.80m
36/0.80 < 0.80m/0.80
as we are dividing by a positive number, we don't have to change the direction of the < sign.
45 < m
or m > 45
so if Ali intends to drive more than 45 miles, Company A's vehicle will be less expensive to rent
