Tiana has 3 gift cards so 25(3) and b is the amount after she buys the blue ray . So 25(3) - the Blu ray =B the amount she has left
Answer:
Step-by-step explanation:
The probability and the parameter
Step-by-step explanation:
The formula for probability in a binomial distribution is where p is the probability of success (ticket with popcorn coupon), n is the number of trials (tickets bought) and x the number of successes desired. In this case p=0.629 (probability of buying a movie ticket with coupon), n=29, and x=17,18,19, ...29.
The probability of more than 16 is equal to the sum of the probability of x=17, 17,18,19, ...29.
Answer:
it would be 66 I hope this helps.
Functions like these are just mattress of plugging in.
Graph: y = 2x+3
Let's just take five numbers: -2, -1, 0, 1, 2
Make a table like the disclosed image, but replace the function at the top-middle with:
y = 2x + 3
Go through each equation by replacing the 'x' in each equation with the given number.
Example:
Number: -2
Function: y = 2x + 3
Plug-in: y = 2(-2) + 3
Simplify: y = -4 + 3
Simplify: y = -1
Repeat this with -1, 0, 1, and 2 to draw the function.
