This property says you can write 3 x (4 + 5) as (3 x 4) + (3 x 5).

distributive property

Step-by-step explanation:

Yes. It works.

Step-by-step explanation:

3 x (4 + 5) = First you have to add 4 + 5 since it's in parentheses, and whatever is in parentheses, you have to do it first. so 4+ 5 = 9. Then you multiply 9 by 3 which gives you 27.

(3 x 4) + (3 x 5) is equivalent to 3 x (4 + 5).

First you do whatever is in parentheses, since they're both in parentheses, I don't think it matters which you do first, but I would do the first problem. 3 x 4 is equal to 12, then 3 x 5 is equal to 15, so you add your answers. 12 + 15 = 27.

So, you can write 3 x (4 + 5) as (3 x 4) + (3 x 5) = 27. They both equal to 27. Hope this clarifies your question.

Also the property is called the distrubitive property.

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;
