Given the function, f(x) = 9 - x :
To evaluate f(4), we must substitute 4 into the given function as an input value for x:
f(4) = 9 - 4
f(4) = 5
Therefore, f(4) = 5.
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.
Given:
nine 5 pound bags
distributed into 10-ounce bags
1 pound = 16 ounces
9 x 5 pounds = 45 pounds
45 pounds * 16 ounces/lbs = 45 * 16 oz = 720 ounces
720 ounces / 10 ounce bags = 720/10 = 72 bags.
The workers at the food pantry will be able to make 72 bags.
So, 3 boxes x 10 markers=
30 markers/ 5=
6 markers each person will get.
