Answer:
x = 11
Step-by-step explanation:
4 - 1 / x - 7 (simplify)
3 / x - 7 = 3/4 (multiply by x - 7)
3 = 3/4 (x - 7)
3 = 3/4x - 5.25 (add 5.25 to both sides)
8.25 = 3/4x (divide both sides by 8.25)
x = 11
sub into the formula to check:
4-1 / 11 - 7
3 / 4
Answer:
3
Step-by-step explanation:
area = l^2 = 9
so,l = 
= 3
Amount of students x Amount of buses
= 32 x 6
= 192 [students]
You need 192 seats since there are 192 students. To find how many rows you need you divide 192 by 8 which gives you 24
24 rows of seats are needed for the students
Answer:
The second graph.
Step-by-step explanation:
The first graph has a negative slope, so that can't be the right answer.
The last graph isn't steep enough to show a rate of 2.5.
This leaves us with the middle graph which is correct.
Answer:
It is an example of an empirical probability.
Step-by-step explanation:
The empirical probability, also called experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
Theoretical probability is probability that is determined on the basis of reasoning.
It is evident that the probability in the question was arrived at after the outcome of 14 days of whether Jerry Gergich spilled his lunch on himself or not.
It's an actual result of an experiment, hence the 12/14 = 0.86 = 86% that he spills his lunch on himself tomorrow.
Hope this Helps!!!
