Answer:
We can describe FOIL using the distributive property of multiplication. For real numbers x, y, and z the distributive property of multiplication states that
Now let 
, where v and w are real numbers.
Then 
Here, we can again use the distributive property of multiplication to get
Hence, it follows that
This is the method of FOIL (first: xv, outside: xw, inside: yv, last: yw)
For example, 
Answer: $14,000
Step-by-step explanation:
Given the following :
Room & Board = $11,500
Work - study = $8000
Grant & scholarship = $9500
Tuition fee = $9500
If she pays balance with a student loan, how much will she need to borrow:
Elisha's bill:
Tuition fee and room and board
($9500 + $11500) = $21,000
Elisha's earning:
Work - study and scholarship & grant
($8000 + $9500) = $17500
Therefore,
Amount to borrow per year :
$21,000 - $17,500 = $3500
For four years :
4 × $3,500 = $14,000
Answer:The answer is 50
Step-by-step explanation:
The first step is to add up the numbers in order to get the outcome
5 red + 20 blue +25 green =5+20+25 =50
Step 2
Probability =no of events /no of outcome
We were asked to find the probability of red
Where red represent event
And the summation of red ,green and blue represents outcome .
So probability of red =5/50 = 1/10
Step 3
Recall in the question ,we were told that the card was selected 500 times ,so we multiply the probability of getting red by 500
1/10 *500 =50
Therefore the probability of drawing a red card from the special deck 500 times is 50 .
Answer:
The probability of making a correct random guess is 0.00053%.
Step-by-step explanation:
Since Clue is a board game in which you must deduce three details surrounding a murder, and in the original game of Clue, the guilty person can be chosen from 66 people, and there are 66 different possible weapons and 99 possible rooms, and at one point in the game, you have narrowed the possibilities down to 44 people, 55 weapons, and 77 rooms, to determine what is the probability of making a random guess of the guilty person, murder weapon, and location from your narrowed-down choices , and the guess being correct, the following calculation must be performed:
(1 / (44x55x77)) x 100 = X
(1 / 186,340) x 100 = X
0.0005366 = X
Therefore, the probability of making a correct random guess is 0.00053%.
