Answer:
D.
and
.
Step-by-step explanation:
We have been given that one a recent trip, Cindy drove her car 290 miles, rounded to the nearest 10 miles, and used 12 gallons of gasoline, rounded to the nearest gallon.
The range of miles driven would be between
because number of miles in rounded to nearest 10 miles.
The range of gallons of gasoline would be
because number of gallons of gasoline in rounded to nearest gallon.
To find mileage, we will divide number of miles by number of gallons.
The possible number of gallons of gasoline will be 12.5 gallons for 285 miles to get the minimum number of miles.
Similarly, the possible number of gallons of gasoline will be 11.5 gallons for 295 miles to get the maximum miles.
Therefore, our required range would be

Answer:the answer is actually C
Step-by-step explanation: I took the test and the answer is C: no correlation exists between variables R and S
The answer is 185 ft 2.
Since it is a parralellogram you have to multiply the base x height.
And it has a 2 right next to it because you multiplied base x height
Hope it helps!~
Answer:
X=6,x=-2
Step-by-step explanation:
To solve this question we will have to follow the step by step procedure
(x-6)(x+2)
x^2+2x-6x-12
Let's continue
x^2-4x-12
Let's factorise
x^2-6x+2x-12
x(x-6)+2(x-6)
(x-6)(x+2)
so to solve further that is to get the value for x
x-6=0
Add 6 to both sides
x=6
x+2=0
Substrate 2 from both sides
x=-2
Therefore x=6,x=-2
