Answer:
5k - 2
Step-by-step explanation:
To evaluate f(2 - k), substitute x = 2 - k into f(x), that is
f(2 - k) = 8 - 5(2 - k) = 8 - 10 + 5k = 5k - 2
Answer:
P=0.54.
Step-by-step explanation:
We know that in a sample of 6500 automobiles found that 1560 of the automobiles were black, 3120 of the automobiles were sedans, and 1170 of the automobiles were black sedans.
We calculate the number of sedans that are not black:
3120-1170=1950
We calculate the number of black cars that are not sedans:
1560-1170=390
The number of automobiles which are black or a sedan is
1950+390+1170=3510.
The probability that the automobile is black or a sedan is:
P=3510/6500
P=0.54.
Answer:
3
Step-by-step explanation:
We want to cancel out the 3y. The second equation has a -y so if we multiply that by 3 we'll get -3y and when we add the ys go away.
The sqft for an area that is 12 by 25 is 300.
2.60 x 300 = 780
It would cost $780.00.
Hope it helps!
