Answer:
47% and 62%
Step-by-step explanation:
1. Drink
The probability that a student buys a drink is 0.47
Step-by-step explanation:
The probability that a student buys a drink will be given by;
( the number of students who bought a drink)/(the total number of students)
We are told that;
Of the 100 students who came to the movie, 62 bought popcorn and 47 bought a drink. Therefore, the required probability is;
47/100= 0.47
0.47 = 47%
2. Popcorn
For popcorn probability, it's basically the same.
The probabilty that a student buys popcorn is 0.62
The probability that a student buys popcorn will be given by;
( the number of students who bought popcorn)/(the total number of students)
So therefore,
62/100 = 0.62
0.62 = 62%
Domain is input/numbers you can use
range is the output you get from inputing the domain
domain=-3,-1,0,1,3
input those numbers for x and get y (range)
y=4(-3)+7
y=-5
y=4(-1)+7
y=3
y=4(0)+7
y=7
y=4(1)+7
y=11
y=4(3)+7
y=19
range is {-5,3,7,11,19}
Answer:
Step-by-step explanation:
The area of each rectangular sheet of cardboard made by the factory is is 2 1/2 square feet. Converting
2 1/2 to improper fraction, it becomes 5/2 square feet.
Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 1/6 square feet. Converting 1 1/6 to improper fraction, it becomes 7/6 square feet.
Therefore, the number of smaller pieces of cardboard that each sheet of cardboard provides is
5/2 ÷ 7/6 = 5/2 × 6/7 = 30/14
= 2.14 pieces
Answer:
Step-by-step explanation:
A radical equation is any equation in which a variable is under a root. This is the only equation in which x is under the square root, so this is the radical equation.
