Nicole is going to see a movie and is taking her 3 kids. Each movie ticket costs $14 and there are an assortment of snacks available to purchase for $4.50 each. How much total money would Nicole have to pay for her family if she were to buy 4 snacks for everybody to share? How much would Nicole have to pay if she bought x snacks for everybody to share?

Four tickets and four snacks comes to a total of $74.00

If she buys x snacks, that cost is 4.50x. so the total for 4 tickets and unknown snacks is 4(14) + 4.5x

Step-by-step explanation:

Nicole + 3 kids is 4 tickets times $14. 4×14=56. Add the snacks. 4×4.50=18. $56+$18=$74

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
