Answer:
-7, then -13, then -19
Step-by-step explanation:
Plug in x values to get y.
y = -2(0) - 7
y = 0 - 7
y = -7
y = -2(3) - 7
y = -6 - 7
y = -13
y = -2(6) - 7
y = -12 - 7
y = -19

Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie
Answer: 0.2
Step-by-step explanation:
Given: The commuting time on a particular train is uniformly distributed over the interval (42,52).
∴ The probability density function of X will be :-
Thus, the required probability :-
Hence, the probability that the commuting time will be less than 44 minutes= 0.2
