According to the line graph, from 2003-2007, the number of drug-induced deaths continued to rise at a faster rate than all others. the numbers for each year are, roughly, 30,000, 30,000, 35,000, 40,000, 40,000.

what is the mean of these statistics?

175,000
40,000
35,000
30,000

35000

Step-by-step explanation:

1) Add up 30000+30000+35000+40000+40000

2) Divide that total by 5 (the number of items you added together in the first step)

3) You get 35000

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

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;
