Amount spent on the last call = $25 - $17.64 = $7.36 = 736 cents
Number of minutes used for last call = 736 / 23 = 32 minutes.
You have 4 options:
4 cards: because you draw cards and don't replace them your chance p changes on every trial, so it can't be a binomial experiment
roll 2 dice until...: a binomial experiment must have a consistent amount of trials, by doing an action until some condition is fulfilled violates this as the amount of trials or throws in this case is random
ask 9 people: there are three options, binomial experiments can only have 2
the only option left is the spinner, which is a binomial experiment
Answer:

Step-by-step explanation:
x=-3
Answer:
-2x
Step-by-step explanation:
The expression itself is -2x. We subtract the coefficients 7 and 9 to get -2.
Answer:
x = - 
Step-by-step explanation:
Given
(x + 5 
) = 
Multiply both sides by 8 to clear the fractions
6(x + 5 ) = 5 ← distribute parenthesis on left side
6x + 33 = 5 ( subtract 33 from both sides )
6x = - 28 ( divide both sides by 6 )
x = 
= -
