Y+7
Y is the variable and 7 is the constant.
Answer:
And replacing we got:
And then the estimator for the standard error is given by:
Step-by-step explanation:
For this case we have the following dataset given:
20.05, 20.56, 20.72, and 20.43
We can assume that the distribution for the sample mean is given by:
And the standard error for this case would be:
And we can estimate the deviation with the sample deviation:
And replacing we got:
And then the estimator for the standard error is given by:
Step-by-step explanation:
length of a rectangle = (3x+4)
breadth of a rectangle =(2x-1)
perimeter of a rectangle =?
we know that,
perimeter of a rectangle=2 (length+breadth)
2 (3x+4)+(2x-1)
(6x+8)+(4x-4)
(6x+4x)+(4+8)
10x+12
x=12-10=2
x=2#
Work in amount of pure acid let x = gallons of pure acid required.
then we have the equation:-
x + 55(0.6) = 0.80(x + 55)
x + 33 = 0.80x + 44
0.20x = 11
x = 11/0.2 = 55 gallons answer
