The vertex would be (5, 27)
Answer:
3/25
Step-by-step explanation:
12% = 
Convert percentage to fraction and then simplify
15 students/45 tacos=? students/450 tacos
15 x 450=6750
6750/45=150
Gary would be making 450 tacos for 150 students
The probability of rolling a 2 is 1/6. If X is a random variable representing the number of 2s that are obtained after rolling a die 23 times, then X follows a binomial distribution with success probability p = 1/6 across n = 23 trials.
The variance of a binomial distribution with parameters p and n is n p (1 - p), so the standard deviation in this case would be
√(23 • 1/6 • 5/6) ≈ 1.8
Answer:
178
Step-by-step explanation:
area of big rectangle : 143
area of small rectangle:20
area of triangle : 15
143+20+15= 178
