We can calculate that e, the amount of euros that has the same value as d u. s dollars, using the equation e=17/20d how many euros have the same amount as 1 u. s dollar

0.85 Euros have the same amount as 1 U.S dollar.

Step-by-step explanation:

The given equation is:   , where amount of Euros and amount of U.S dollar.

Now for 1 U.S dollar, we need to plug into the above equation. So, we will get.........

Thus, 0.85 Euros have the same amount as 1 U.S dollar.

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;
