Step-by-step explanation:
Error = 7.7-7.4=0.3
% error= 0.3/7.7×100 % error= 3.89%
= 3.9% to the nearest tenth
Answer:
1/6
1/6
1/36
Events A and B are independent
Step-by-step explanation:
Suppose:
A = event that first die lands on 2
B = event that second die lands on 2
Sample space:
Die 1 = 1,2,3,4,5,6
Die 2 = 1,2,3,4,5,6
Sample space of both die combined is attached below
Probability = (total number of required outcomes / total number of possible outcomes)
Probability that first die lands on 2:
P(A) = 1/6
Probability that second die lands on 2:
P(B) = 1/6
Probability of A and B:
P(A and B) = 1/6 × 1/6 = 1/36
Evebts A and B are independent because, the outcome of one event does not affect the occurrence of the other event.
Answer:
C. 314 units2
Step-by-step explanation:
Sphere Formula:
SA=4πr²
SA= 4×3.14×5²= 314 units2
In this case if x<100 George will be losing money. So he will only earn a profit when he sells more than 100 DVDs. Essentially (x-100) represents his break-even point.
