Answer:
P(A and B) = 7/80
Step-by-step explanation:
The given values of the probabilities of the different events are;
P(A) = 7/20
P(B) = 7/20
P(A or B) = 49/80
P(A and B) = Required
We have by probability theory for any event;
P(A or B) = P(A) + P(B) - P(A and B)
Therefore;
P(A and B) = P(A) + P(B) - P(A or B)
Plugging in the values gives;
P(A and B) = 7/20 + 7/20 - 49/80 = 7/80
∴ P(A and B) = 7/80
This is called diffusion.
Answer: A
Step-by-step explanation: I use synthetic division for problems like these:
-3 | 4 2 -18 38
4 -10 12 2
Since -3 + 3 = 0, we use -3 in this process. Write out the coefficients in order separate from -3. Next, bring down the 4 and multiply -3 by 4 = -12. Add 2 and -12 = -10. Multiply -10 by -3 = 30. Add 30 to -18 to get 12. Multiply 12 and -3 = -36. Add -36 and 38 = 2

Answer:
D. 6
Step-by-step explanation:
One-pound bags sell for $2
Three-pound bags sell for $5
9 bags were sold for $36
6*$5=$30 (three pound bags)
3*$2=$6 (one pound bags)
$30+$6=$36
So 6 of the three-pound bags were sold
