Answer:
d) Conclude that the population mean annual consumption of beer and cider in Milwaukee is greater than 26.8 gallons and hence higher than throughout the United States.
Step-by-step explanation:
We have a hypothesis test about the true mean consumptionof beer and cider for U.S. 21+ years-old consumers with the following null and alternative hypothesis:
The result of the test is to reject the null hypothesis.
This means that there is evidence to support the claim that beer and cider consumption was higher than the national average in Milwaukee in 2017 .
(1) 34.8 liters
(2) $63.55
Solution:
(1) There is a mistake in question. It is 42 liters.
Total gasoline a car can hold = 42 liters
Liters of gasoline filled in beginning of the week = 35.8
Liters of gasoline used during the week = 28.6
Remaining liters of gasoline in the tank = 35.8 – 28.6
= 7.2 liters
Quantity of gasoline need to buy to fill the tank completely
= Total capacity – Remaining gas in the tank
= 42 liters – 7.2 liters
= 34.8 liters
Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.
Option B is the correct answer.
(2)
Shamika earns in first week = $25.75
Shamika earns in next week = $37.80
Total money Shamika have = First week earning + Second week earning
= $25.75 + $37.80
= $63.55
Don't add or subtract spending money, because the question is how much she have from these two weeks.
Hence Shamika have $63.55 from these two weeks.
We will calculate this by using ratios and because these two triangles are similar, which is very important.
Explanation:
We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.
9 : 21 = 18 : x
x = (21*18)/9
x = 378/9
x = 42.
The correct answer is B. 42.
Answer:
3 / 5
Step-by-step explanation:
Total = 5
Probability of spinning white exactly 3 = 3 / 5
Answer:
52 yd
Step-by-step explanation:
The formula for arc length is s = rФ, where r is the radius and Ф is the central angle in radians.
Here the central angle is 300° and the radius is 10 yd.
Convert 300° to radians:
π rad
Multiply 300° by the conversion factor ------------
180°
obtaining
(300/180)π = 5.2 rad
Then the arc length is s = rФ = (10 yd)(5.2 rad) = 52 yd
