Answer:
you used 75.8 gb of data
Step-by-step explanation:
19.95-23.74=3.79 money spend just on data
3.79/0.05=75.8 gb of data
double check, 75.8x0.05=3.79
Answer:
a) 0.857
b) 0.571
c) 1
Step-by-step explanation:
Based on the data given, we have
- 18 juniors
- 10 seniors
- 6 female seniors
- 10-6 = 4 male seniors
- 12 junior males
- 18-12 = 6 junior female
- 6+6 = 12 female
- 4+12 = 16 male
- A total of 28 students
The probability of each union of events is obtained by summing the probabilities of the separated events and substracting the intersection. I will abbreviate female by F, junior by J, male by M, senior by S. We have
- P(J U F) = P(J) + P(F) - P(JF) = 18/28+12/28-6/28 = 24/28 = 0.857
- P(S U F) = P(S) + P(F) - P(SF) = 10/28 + 12/28 - 6/28 = 16/28 = 0.571
- P(J U S) = P(J) + P(S) - P(JS) = 18/28 + 10/28 - 0 = 1
Note that a student cant be Junior and Senior at the same time, so the probability of the combined event is 0. The probability of the union is 1 because every student is either Junior or Senior.
6x-8
There is 8 less (so -8) than the product of 6 and x (so 6x).
Answer:
I got 0.475 hope it helps!
ohh sorry didn't see the answer as a fraction part.
I tried it again and got 19/40 I hope you get it right!
Answer:
In a multiplication problem, the product is the answer, so the product is 10.
