Answer:
f(x)=-|x+1|-2
Step-by-step explanation:
Option B
For this problem, let x be the width and y be the length of the rectangle. We use these variable to make an equation from the perimeter.
Perimeter = 2*Length + 2*WIdth
Perimeter = 2y + 2x
70 = 2y + 2x
The area of a rectangle is equal to the product of x and y. Since we want the equation in terms of x only, let's find y in terms of x.
y = 35 - x
Hence, the formula for area is:
Area = xy
Area = x(35 -x)
Area = 35x - x²
Answer: 311.542 pounds or .155771 tons
Step-by-step explanation:
1 cubic foot = 7.48 gallons
1 gallon = 8.33 pounds
so...
1 cubic foot = 7.48 • 8.33 = 62.3084 pounds
5 cubic feet = 62.3084 • 5 = 311.542
1 ton = 2000 pounds
311.542/2000 = .155771 tons
Answer:
I think you can add 9 +8 to get your finial answer.
The mean of sample means is the same as the mean of the underlying distribution.
The standard deviation of sample means is the original distribution sample mean divided by the square root of the number of samples.
Mean of sample mean distribution: 64
SD of sample mean distribution: 4/√64 = 1/2
