Answer:
1. P(S) = 373/580
2. P(S|A) = 53/116
3. P(S|Pa) = 481/580
Step-by-step explanation:
Given
---------------------Sale ----- No Sale-----Total
Aggressive ----265 --------315 ----------580
Passive ----------481 ---------99 -----------580
Total --------------746---------414------------1160
A = aggressive approach,
Pa = passive approach,
S = sale,
N= no sale.
(a) Computing P(S)
This is calculated as the division of customers that participated in sales by total customers
Customers that participated in sales = 265 + 481 = 746
Total Customers = 1160
P(S) = 746/1160
P(S) = 373/580
b.
P(S|A) means that the probability that a sales occur given that the aggressive method was used.
To solve this, we check the cell where Sales and Aggressive intersect
The cell element = 265
Total = 580
P(S|A) = 265/580
P(S|A) = 265/580
P(S|A) = 53/116
c.
P(S|Pa) means that the probability that a sales occur given that the passive method was used.
To solve this, we check the cell where Sales and Passive intersect
The cell element = 481
Total = 580
P(S|Pa) = 481/580
What are you talking about ?
To find out the answer, let's factor out -42 (as if it's a positive number).
42: 1 x 42, 2 x 21, 3 x 14, 6 x 7.
With these given factors and due to the product being negative, we will go on and off with them being negative to find which sum up to 11.
Let's try 1 and 42.
-1 + 42 = 41
-42 + 1 = -41.
1 x 41 is not our answer.
Let's try 2 and 21.
2 - 21 = -19
-2 + 21 = 19
2 x 21 is not our answer.
Let's try 3 and 14.
-3 + 14 = 11
3 - 14 = -11.
Your answer is:
-3 and 14 sum up to 11 and make a product of -42.
-3 and 14 are your numbers.
I hope this helps!
Answer:
15
Step-by-step explanation:
There are 4/4 to make a whole so 2 1/2 cups would be 10 'scoops' and 1 1/4 would be 5 'scoops'. Add 10 + 5 to get a total of 15 scoops.
Hope that helps and have a great day!
<span>take 5x as a factor of each term
5x(x^2 -4x - 12)
you now need to factor the quadratic...
hope it helps
