Subtraction of whole numbers is commutative. True or False

1 answer:

3 0

It is False.

If a property is commutative in subtraction it means: x - y is the same as y - x.

For example 5 - 3 = 2, but 3 - 5 = -2 so subtraction is not commutative.

But 5 + 3 = 8 , is the same as 3 + 5 = 8.

Addition is Commutative, but Subtraction is not commutative.

So the statement that subtraction of whole numbers is commutative is False.

What is the solution of the system

ozzi

The solution to the system of equation is (14, 6)

1 / 2 x = 10 - 1 / 2 y

8 = x -y

Therefore, let's combine the equation.

<h3>Simultaneous equation:</h3>

1 / 2 x + 1 / 2 y = 10

x - y = 8

x + y = 20

x - y = 8

2y = 12

y = 12 / 2

y = 6

x = 20 - 6

x = 14

Therefore, the solution of the system of equation is (14, 6)

Based on the NYC Department of Health Community Health Survey in 2010, a 95% confidence interval for the proportion of New Yorke

g100num [7]

Answer:

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

Step-by-step explanation:

The lower bound of the confidence interval is 29.9%.

So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.

Out of 6 million, that is:

0.299*6000000 = 1,794,000

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
