Emmett is ordering his favorite frozen yogurt dessert. He’s buying one cup of regular frozen yogurt for $3.25. For every fruit topping he must pay $1.25 and for every candy topping he must pay $0.75. Write an equation that represents the cost of one frozen yogurt.

3.25+1.25t+0.75c=d

Step-by-step explanation:

The d is how much the frozen yogurt costs now

1/800 is the right answer

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;
