If you are charging 5 per hour use h to determine how many hours and add 10 for the connection fee
5h+10
F(x) = 12/(4x+2)
x = -1
f(-1) = 12 / [4(-1)+2]
f(-1) = 12 / (-4+2)
f(-1) = 12 / -2
f(-1) = -6
In this item, it is not given that there has to be specific arrangement or order as to how the questions are going to be answered. Hence, the concept that can be used in order to answer this item is the concept of combination which states that,
nCr = n! / (r!)(n - r)!
This is read as "combination of n taken r". In this item, n = 10 and r = 4. Substituting the known vaues to the equation,
10C4 = (10!) / (4!)(10 - 4)!
10C4 = 210
Therefore, the number of which is which the questions can be answered is 210.
Answer:
Step-by-step explanation:
so what you want to do is take -1/4x+2 3/4 and solve for x and once you got what x is plug it in to the second part 1/2^x +1
Answer:
The numbers needed to fill each box are in the image attached
Step-by-step explanation:
The probability of the coin landing on heads is 2/7, so the probability of it landing on tails is 1 - 2/7 = 5/7
The probability of landing heads 2 times is:
P = (2/7) * (2/7) = 4/49
The probability of landing heads and then tails is:
P = (2/7) * (5/7) = 10/49
The probability of landing tails and then heads is:
P = (5/7) * (2/7) = 10/49
The probability of landing tails 2 times is:
P = (5/7) * (5/7) = 25/49
The numbers needed to fill each box are in the image attached.
