Step-by-step explanation:
STEP 1
Calculate the slope from 2 points.
STEP 2
Substitute either point into the equation. You can use either (3,7) or (5,11)
STEP 3
Solve for b, which is the y-intercept of the line.
STEP 4
Substitute b, -1, into the equation from step 2.
34.45 because you just have to multiply 5.3 by 6.5
7.25 hour is better because multiply by eleven and its 79.75 which is higher than the on on the table
Using probability concepts, it is found that P(S and D) = 0.1275.
-----------------------
- A probability is the <u>number of desired outcomes divided by the number of desired outcomes</u>.
- In a standard deck, there are 52 cards.
- Of those, 13 are spades, and 13 are diamond.
- The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

Thus, P(S and D) = 0.1275.
