<u>Answer</u>:
B) The perimeter of the rectangle is 28 units.
E) The coordinates for the fourth vertex of the rectangle are (−5, −3).
<u>Step-by-step explanation</u>:
The length of the rectangle is 9 and width is 5.
- The perimeter is 2( 9 + 5 ) = 28 units
<em>as the upper one is right. Option A eliminated. </em>
- The coordinates for the fourth vertex of the rectangle are (−5, −3).
<em>as the upper one is right. option C and D will be eliminated.</em>

Answer:
A one-tailed hypothesis will be used to perform the test.
Step-by-step explanation:
The purpose of the marketing research consultant hired by Coca-Cola is to determine whether the the proportion of customers who prefer Coke to other brands is over 50%.
The marketing research consultant selected a random sample of <em>n</em> = 200 customers. The sample proportion of people who favored Coca-Cola over other brands was 55%.
The marketing research consultant can perform a single proportion hypothesis test to determine whether greater than 50% of customers prefer Coca-Cola to other brands.
Since we need to determine whether the population percentage is greater than a null value, the hypothesis is not two-tailed.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of people who favor Coca-Cola over other brands was 55%, i.e. <em>p</em> = 0.50.
<em>Hₐ</em>: The proportion of people who favor Coca-Cola over other brands was more than 55%, i.e. <em>p</em> > 0.50.
Thus, a one-tailed hypothesis will be used to perform the test.
