Answer:
x = number of days
y = number of remaining photos saved to her camera roll.
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The number of pictures saved in the camera roll (2,500) minus the amount of photos that she deletes per day (50) multiplied by the number of days (x) must be equal to the number of photos remaining.
y =2,500- 50x
The variables are x and y.
Where x is the number of days and y is the number of remaining photos.
Feel free to ask for more if needed or if you did not understand something
you can get the vertex of an absolute value expression by y = | x - h | + k, where the vertex is at (h, k).
now, as a matter of transformations, the negative in front of the absolute value expresssion, means the graph of it upside-down.
the graph of | x - h | + k, is like the letter V, comes down, it makes an apex and goes right back up, the apex is of course at the vertex (h,k).
so -|x - 4| + 5, has a vertex at (4,5), and is upside-down, like Ʌ, which means, it comes from the botttom, goes up up up, hits (4,5) and then goes right back down.
so its range is from y = 5, and back down, namely to -∞, so (-∞ , 5].
Answer:
you should probably charge around 15-20 dollars. personally i think you should charge 15 and see how many sales you get and as your demand increases, increase the price.
Answer:
a) 0.0255
b) 0.7050
c) 0.2945
Step-by-step explanation:
Probability that one of those sampled saying that Roosevelt was the best president since World War II = 330/2062 = 0.16
Probability that one of those sampled don't mention Roosevelt = (2062 - 330)/2062 = 1732/2062 = 0.84
a) The probability that both adults picked say Franklin Roosevelt was the best president since World War II = (330/2062) × (329/2061) = 0.0255
b) The probability that neither of the two adults say Franklin Roosevelt was the best president since World War II = (1732/2062) × (1731/2061) = 0.7050
c) The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = Probability that one of the two adults mention Roosevelt + Probability that the two adults mention Roosevelt
Probability that one of the adults mention Roosevelt = [(330/2062) × (1732/2061)] + [(1732/2062) × (330/2061)] = 0.269
Probability that two of the adults mention Roosevelt has been done in (a) and it is equal to 0.0255
probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = 0.269 + 0.0255 = 0.2945
Answer:
Pavilion seats: 1000
Lawn seats: 600
Step-by-step explanation:
Let p represent tickets for pavilion seats and l represent that of lawn seats
Then the total number of tickets is
The total revenue is
We make p the subject in the first equation:
This implies that:
Put equation (3) into equation (2).
This gives us:
Expand to get:
Group similar terms:
Simplify to get
Put l=600 into equation (3) to get:
Therefore 1000 pavilion seats and 600 lawn seats were sold.
