Answer:
in my opinon, this table is proportional
You need to expand (4x-7)(x+3), multiplying each term in the first bracket by each term in the second bracket, in order to get 4x^2+5x-21. Hope that helps!
Use combination
There are 4 queen cards in a deck of 52 cards
Probability = 4C2 / 52C2
I calculate 4C2 first
4C2 = 4! / (2! 2!)
4C2 = (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)
4C2 = 6
Then I calculate 52C2
52C2 = 52! / (50! 2!)
52C2 = (52 × 51)/2
52C2 = 1.326
Hence, the probability is
Probability = 4C2 / 52C2
Probability = 6/1,326
Probability = 1/221
Answer:
The y-intercept in this case is 4800
Step-by-step explanation:
The equation of a line graph is ;
y = mx + c
with respect to the given equation in the question, the y-intercept in this case is 4,800
In this case the y-intercept represent the height from which the plane starts to descend
Answer:
Step-by-step explanation:
We can assume each shelve takes the same amount of wood to make. So if 30 inches are needed for one shelve, 30*6 inches of wood will be needed for 6 shelves. 30*6=180, so 180 inches of wood is needed to make 6 shelves. However, the question asks for the final answer to be in feet. There are 12 inches in a foot so we can divide by 12 to find the amount of feet needed to make 6 shelves. 180/12=15. Therefore, 15 feet are needed to make 6 shelves.
