Which equation shows the commutative property of addition? 2 = 2 + 0
19 = 8 + 7 + 4
0 + 8 = 8
1 + 5 = 5 + 1

D 1+5=5+1

Step-by-step explanation: Commutative property of addition Changing the order of addends does not change the sum.

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;
