Answer:
= -3x2 - 11x + 13
Step-by-step explanation:
=( +9) + (-3x2 - 11x + 4)
= -3x2 - 11x + 4 + 9
= -3x2 - 11x + 13
Is that 14 times 31 or 14x times 13 or...
(³⁰/₁₀₀)(²⁰/₁₀₀)(⁷/₁₂)
(³/₁₀)(¹/₅)(⁷/₁₂)
(¹/₁₀)(¹/₅)(⁷/₄)
⁷/₂₀₀
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%
