1 9/10 + 3/4 plz need help I’m tired and can’t do math I also need it simplified

4

Step-by-step explanation:

take 1 9/10 change it to 19/10 + 3/4. You will need to have a common denominator for any addition or subtraction with fractions. We multiply 19/10 by 4 to get 76/40. Multiply 3/4 by 10 to get 30/40. Now we have a common denominator.

Add across 76 + 30 = 106/40. Now simplify. How many times does 40 go into 106?

4 times. No remainder.

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;
