Answer:
OPTION A
Step-by-step explanation:
4(0.5x+2.5y-0.7x-1.3y+4)
2x + 10y-2.8x-5.2y+16
-0.8x +4.8y +16
Answer:
The dependent variable depends on the independent variable.
Step-by-step explanation:
- The variable whose values are deliberately changed by the researcher in order to obtain the desired outcome is called independent variable...
- The values of the independent variable can be changed as per requirement, by the researcher...
- Manipulation can be done in the values of independent variable, but the researcher observes the value of a dependent variable during an experiment.
- An independent variable is a presumed cause whereas dependent variable is a measured effect.
- In a simple linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable, which means y depends on x
Answer:
Length ≈ 20 feet (rounded down nearest 10th feet)
Width ≈ 20 feet (rounded up to nearest 10th feet)
Step-by-step explanation:
Find Length and Width
Width = Length - 4 feet
Area = 42 ft²
Area = L x W
42 = L x (L - 4)
42 = 2L - 4
42 + 4 = 2L - 4 + 4
2L = 46
2L/2 = 46/2
L = 23
L ≈ 20 feet
Width = 23 - 4
Width = 19 feet
Width ≈ 20 feet
Answer:
Step-by-step explanation:
-8 ; -16
Difference = -8 - (-16) = -8 + 16 = 8
In general and here, when we have an object with a constant cross section of area A, the volume V = A L, where L is the length.
L = V / A = 330 / 55 = 6 cm
Answer: 6 cm
