Given:
Arnold has $24 to spend at the movies.
Ticket = $12
Popcorn is double the price of the soda.
The soda and candy bar are same price.
To find:
The price for the soda.
Solution:
Let x be the price of soda.
According to the question,
Price of candy = Price of soda = x
Price of popcorn = 2(price of soda) = 2x
Total amount = Ticket + Popcorn + Soda + Candy
Divide both sides by 4.
Therefore, the price of soda is $3.
N = 20, the number of questions
p = 1/5 = 0.2, the probability of making a correct guess
q = 1 - p = 0.8, the probability of making an incorrect guess.
Expected success = 60% or 6 of 10.
From the binomial distribution,
P(6 of 10) = ₁₀C₆ p⁶q⁴
= 210*0.2⁶*0.8⁴ = 0.0055
Answer: 0.0055
The second and fourth one are rational. They are perfect squares and are terminating or are fractions
Answer:
-1/2y-3
Step-by-step explanation:
4y-9/2y-3
8/2y-9/2y-3
-1/2y-3
9x^2+ 3x -2
= 9x^2+ (6x -3x) -2
= (9x^2+ 6x)+ (-3x -2)
= 3x(3x+2) -1(3x+2)
= (3x-1)(3x+2)
The factors of 9x^2+3x-2 are 3x-1 and 3x+2~
