Answer: Subtraction Property of Equality

<em>Step-by-step explanation:</em> The Subtraction Property of Equality tells us that

we can subtract the same quantity, or equal quantities,

from both sides of an equation.

To get from the statement 7x + 11 = 39 to 7x = 28,

we subtract 11 from both sides to get 7x = 28.

Round 733,712 to the nearest thousand<br> 733,712 ~
lions [1.4K]

Answer:

734,000

Step-by-step explanation:

The thousands digit is the fourth digit from the right (<u>1</u>000) so we start by underlining that digit.

73<u>3</u>,712

Look at the digit to the right of the underlined digit. If the number is 5 or more, add one to the underlined digit. Since 7 is 5 or more, we add one to the underlined digit.

All of the digits behind the underlined digits turn to zeros to hold the place values.

lorasvet [3.4K]

Answer:

1 is the answer

Step-by-step explanation:

Given that the U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions.

H_0: p=0.113\\H_a: p >0.113

(Right tailed test for testing of a sample proportion with population proportion)

Suppose a sample of 400 U.S. workers is collected in 2014 to determine whether union efforts to organize have increased union membership at 0.025 level of significance.

Test statistic Z = 1.31

p value for this right tailed test would be 0.095

This p value is greater than 0.025

Hence at 2.5%  significance level the conclusion is correct

1 is the answer.
