Isolate the variable y
Line a: 3y = x+6
y = 1/3x + 2
Line b: 3y = x+18
y = 1/3 x + 6
Line c: 3y = 2x+9
y = 2/3x +3
Explanation:
Lines a and b are parallel because they have the same slope of 1/3.
Answer:
Not an arithmetic sequence
Step-by-step explanation:
For the sequence to be arithmetic there must be a common difference between consecutive terms.
- 7 - (- 3) = - 7 + 3 = - 4
- 10 - (- 7) = - 10 + 7 = - 3
- 14 - (- 10) = - 14 + 10 = - 4
The differences are not common , hence not an arithmetic sequence
Answer:
y = 3x - 2
Step-by-step explanation:
The number beside the x is the slope. The number at the end of the equation is the y-intercept.
All the answers are in this form:
y = mx + b
m is the slope.
b is the y-intercept.
With a 3 filled in for slope and -2 filled in for the y-intercept, you get:
y = 3x + -2
is the same as,
y = 3x - 2
By definition, the area of a rectangle is given by:
Where
l: length of the rectangle
w: width of the rectangle
Therefore, substituting values we have:
Rewriting the expression we have:
Answer:
The area of the rectangle as monomial is given by:
Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
