Answer:
I'm not sure what that U is for.
The answer is 459,461 These two do add to 920
Step-by-step explanation:
Remark
I'm going to make sure you are using consecutive odd numbers.
Let the smaller number = 2x - 1
Let the larger number = 2x + 1
Equation
2x - 1 + 2x + 1 = 920
4x = 920
x = 230
The consecutive numbers are 2*230 - 1 = 459
and 2*230 + 1 = 461
Answer:
2:15 p.m.
Step-by-step explanation:
Starting time 1:40 p.m.
Time on subway <u>+0:17
</u>
Time off subway 1:57 p.m.
Time walking <u>+0:18
</u>
Time at apartment 1:75
When the minutes are more than 60, you subtract 60 from the minutes and add 1 to the hours.
1 :75
+1<u> - :60
</u>
2 :15 p.m.
Daniel arrived at the apartment at 2:15 p.m.
In the given figure we have two similar triangles:
a) Triangle ABC
b) Triangle ADE
Two sides of triangle ABC are 2 and x
The two corresponding sides of triangle ADE are (2+1)=3 and 1
The ratio of corresponding sides of similar triangles is always equal, so we can write:
Therefore, the measure of x will be 2/3
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.
