i. No SPINNER SHOWN?
j. NO SPINNER SHOWN?
Step-by-step explanation:
P( at least 8 correct ) =
<span>........P( 8 ) + P( 9 ) + P( 10 ) = </span>
<span>........(10 C 8).5^10 + (10 C 9).5^10 + (10 C 10).5^10 = ........56*.5^10 = 0.0546875 </span>
<span>Note: Let C denote correct and I denote incorrect. Suppose that guessing results in 8 correct and 2 incorrect answers. One possible outcome is CCCCCCCCII, for example. We can think of the number of ways of getting exactly 8 correct to be the same as the number of ways of selecting 8 spots for the correct answers times the number of ways of selecting two spots for the remaining two answers. There are (10 C 8) ways to select the positions for the correct answers and precisely one way to select the remaining two positions for the incorrect answers. Therefore, there are there are 10 C 8 = 45 ways to get 8 correct. Similarly, there are 10 C 9 = 10 ways to get 9 correct, and 10 C 10 = 1 way to get all 10 correct.</span>
Answer: F(x, y) = 40x + 25y
Step-by-step explanation:
Given the following :
x = number of leather wallets
y = number of canvas wallets
PROFIT on canvas wallet = $25
PROFIT on leather wallet = $40
Function that calculates the total profit on both wallets:
Profit on each wallet type is the product of the profit per wallet and the number of wallet.
The total profit generated on each wallet type is given by :
F(x) = 40x - - - - (1) leather wallet
F(y) = 25y - - - - (2) canvas wallet
Adding (1) and (2) to get total profit on both wallets:
F(x, y) = 40x + 25y
Answer:
put the cords on a chart
Step-by-step explanation:
Answer: (a - 1)/(3a - 2)
Step-by-step explanation:
First lets find a common factor in all of those numbers. We can factor out 'a'!
We're then left with (2a^2 + a - 3)/(6a^2 + 5a - 6)
Now we need to find some more factors.
Lets start at the top.
Factors of -3 are -1, 3, -3, 1
We can therefore factorize the top line to be:
(2a + 3)(a - 1)/(6a^2 + 5a -6)
Sweet! Now lets see if one of those two factors is a factor of the bottom line.
Factors of -6 are -1, 6, 2, -3, -2, 3, -6, 1
We can factorize the bottom line!
(2a + 3)(a - 1)/(3a - 2)(2a + 3)
Now to simplify
= (a - 1)/(3a - 2)
annnd we are done.
