In this question, the profit of the restaurant after t months is given by a polynomial function. To find when it begins to show a profit, we find the numerical values of the function for t, and it shows a profit when 
Profit after t months:

0 months:
This is P(0). So

1 month:
This is P(1). So

2 months:
This is P(2). So

3 months:
This is P(3). So

4 months:
This is P(4). So

5 months:
This is P(5). So

6 months:
This is P(6). So

7 months:
This is `P(7). So

After 7 months it shows profit, so it starts showing profit on the 6th month, and thus, the correct answer is given by option D.

Answer: 0.65
Step-by-step explanation:
Let A denote that moviegoers were female and B denotes that moviegoers were under age 25.
As per given we have,
P(A)=0.56 P(B)=0.26 P(A∩B)=0.17
Using formula ,

Hence, the probability that a moviegoer is either female or under age 25 = 0.65
Answer: The proportion of students spending at least 2 hours on social media equals 0.7257 .
Step-by-step explanation:
Given : The typical college freshman spends an average of μ=150 minutes per day, with a standard deviation of σ=50 minutes, on social media.
The distribution of time on social media is known to be Normal.
Let x be the number of minutes spent on social media.
Then, the probability that students spending at least 2 hours (2 hours = 120 minutes as 1 hour = 60 minutes) on social media would be:

Hence, the proportion of students spending at least 2 hours on social media equals 0.7257 .
Answer:
9.75ft
Step-by-step explanation:
Step one:
Given data
Dimension of the cylinder
Diameter= 6.5 ft
Height= 12.5 ft
You measure the level of milk to be 2.75 ft from the brim
Required
The dept of the milk in the cylinder
Step two:
to get the depth, we need to subtract the measured level from the brim from the height of the cylinder
= 12.5-2.75
=9.75 ft
Hence the Depth of the milk is 9.75ft
Yes. The original price of the dozen added to the price of berries (.5) multiplied by the amount(b) is the same equational representation to the right of the equal sign.
