8x(40+7)=(8x )+(8x7 what is the missing number
Hitman42 [59]
Well since the first expression says 8x(40+7) the answer would be 40 that is missing

Since your splitting 47 into 40 and 7 and multiplying both of them by 8 the answer would be 40

Each day, Leila records the number of news articles she reads. Here are her results for the last nine days.
Daniel [21]
The mode is whatever number that repeats itself the most, which would be 3 in this case. To find the range you would find the difference between the highest number and the lowest number. The highest number is 8 and the lowest is 1 so 8-1=7. The range is 7.

Answer: (1) 42%, (2) 60%, (3) 75%.


Step-by-step explanation: The calculations are as follows

(1) Given that

P(A) = 0.70,  P(B) = 0.25  and P(A and B) = 0.30 ≠ 0. So, the conditional probability of even B when event A has already occured is given by

P(B/A)=\dfrac{p(B\cap A)}{P(A)}=\dfrac{0.30}{0.70}=0.42.

Therefore, the answer is 42%. Also, since the intersection of A and B is not a null set, so these events are dependent events.

(2) Given that

P(A) = 0.40,  P(B) = 0.60  and P(A and B) = 0.24 ≠ 0. So, the conditional probability of even B when event A has already occured is given by

P(B/A)=\dfrac{p(B\cap A)}{P(A)}=\dfrac{0.24}{0.40}=0.60.

Therefore, the answer is 60%. Also, since the intersection of A and B is not a null set, so these events are dependent events.

(3) Given that

P(A) = 0.33,  P(B) = 0.50  and P(A and B) = 0.25 ≠ 0. So, the conditional probability of even B when event A has already occured is given by

P(B/A)=\dfrac{p(B\cap A)}{P(A)}=\dfrac{0.25}{0.33}=0.75.

Therefore, the answer is 75%. Also, since the intersection of A and B is not a null set, so these events are dependent events.

Thus, the answers are 42%, 602% and 75%.
