Answer:
x=(T-2y)/2
Step-by-step explanation:
Answer:27
Step-by-step explanation:
3x 11 is 33 and 3 x 5 is 15 then you would do 1 x 2 which is 2 then you would add 2 to 33 which is 35 then subtract 15 which is 20 then add 7 to get 27
Answer:
25% decrease
Step-by-step explanation:
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.
4x-3 is the answer because you subtract like terms. 7x-3x=4x and -5-(-2)=-3
