The average monthly rent for one-bedroom apartments in Chattanooga has been $1200. Because of the downturn in the real estate market, it is believed that there has been a decrease in the average rental. The correct hypotheses to be tested are:_______
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is b
Step-by-step explanation:
From the question we are told that
The average monthly rent for one-bedroom apartment in Chattanooga has been
[tex]\mu = \$ 1200[/tex]
This mean that the null hypothesis is
[tex]H_o : \mu = \$ 1200[/tex]
Generally given from the question that it is believed that there has been a decrease in the average rental , it then mean that the alternative hypothesis is
[tex]H_a : \mu < \$ 1200[/tex]

Mila is deciding between two parking garages. Garage A charges an initial fee of $7 to park plus $4 per hour. Garage B charges an initial fee of $3 to park plus $5 per hour. Let AA represent the amount Garage A would charge if Mila parks for tt hours, and let BB represent the amount Garage B would charge if Mila parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.
Answer:
I would do B
Step-by-step explanation:
It is cheaper
Answer
A=4t+7
B=B= 5t+35t+3
Step-by-step explanation:
Garage A is cheaper than Garage B when tt > 4 hours.

Mr. Jones has 3/4 cup of fertilizer. He will use a 1/8 cup measuring scoop to pour all of the fertilizer onto his plants. How many times will Mr. Jones fill the measuring scoop with fertilizer? Write your answer in the box.
Answer:
6 times
Step-by-step explanation:
We will have to divide in order to solve this problem.
[tex]\frac{3}{4}[/tex]÷[tex]\frac{1}{8}[/tex]
We will have to find the reciprocal of 1/8, which is basically flipping it, so it is 8.
After, we will have to multiply 3/4x8. The product would come out as 24/4, and if you simplify it, the answer will be 6 times.
water is draining from a 300ml bottle at a rate of 2ml per second. How many seconds will it take for half of the water to drain?
Answer:
need points
Step-by-step explanation:
Evaluate the formula for the given values of the variables.
d = rt; r = 54 miles per hour, t = 3 hours
O d = 324 miles
O d = 18 miles
O d = 162 miles
O d = 57 miles
Answer:
d=162 miles
Step-by-step explanation:
The formula is d=rt, so the distance is the rate multiplied by the time. Thus, it is 54 times 3 or 162.
The distance that an object falls varies directly with the square of the time it falls. If an
object falls 11 feet in 2 seconds, how long does it take the object to fall 275 feet?

Subtract 8y^2-5y+7 from 2y^2+7y+11
Answer:
6[tex]y^{2}[/tex] - 12[tex]y[/tex] - 4
Step-by-step explanation:
(8[tex]y^{2}[/tex] - 5[tex]y[/tex] + 7) - (2
8 - 2 = 6
-5 - 7 = -12
7 - 11 = -4

Wilma can mow the lawn in 4 hours. If Kyle helps her with another mower, the lawn can be mowed in 3 hours. How many hours would it take Kyle if he worked alone?
Answer:
12 hours
Step-by-step explanation:
Let w = Wilma alone
Let k = Kyle alone
Let t = Working together
Given the following data;
Time it took Wilma = 4 hours
Time it took them together = 3 hours
Time it took Kyle = x
To find the time it will take Kyle, we would use this arithmetical expression;
[tex] \frac {1}{w} + \frac {1}{k} = \frac {1}{t}[/tex]
Substituting into the equation, we have;
[tex] \frac {1}{4} + \frac {1}{x} = \frac {1}{3}[/tex]
Lowest common denominator (LCD) = 12x
Multiplying all through by "12x" we have;
[tex] 12x * \frac {1}{4} + 12x * \frac {1}{x} = 12x * \frac {1}{3}[/tex]
Simplifying the equation, we have;
[tex] 3x + 12 = 4x[/tex]
Rearranging the equation, we have;
[tex] 4x - 3x = 12[/tex]
x = 12 hours.
Therefore, it would take Kyle 12 hours to mow if he worked alone.
