From the excel plotting, we see that the least square regression equation is given by:
m=(7.25-2.65)/(2009-1978)
m=0.15
thus the equation will be:
0.15(x-0)=y-2.65
y=0.15x-2.65
b] Using the equation we can approximate the hourly wage in 2025 as follows:
x=(2025-1978)=47
y=0.15(47)-2.65
y=7.05-2.65
y=4.4
The plot is as shown in the figure:
Answer:
45
OThey did not covert the 18 months to year
Step-by-step explanation:
I= PxRxT. 18/12=1.5
I=500x0.06x1.5
I=45
Answer:
Direct Material Quantity Variance = 825 Unfavourable
Step-by-step explanation
Direct Material Quantity Variance =
( Actual Quantity used - Standard Quantity allowed ) × Standard price per unit
{15000- (3lbs × 4900units)} × $2.75
{ 15000-14700 } × 2.75
Direct Material Quantity Variance =825 unfavourable
This is unfavourable as the company had 14700 lbs available but instead the company actually used 15000 lbs .
Answer:
Andy is incorrect
Step-by-step explanation:
[See attachment for complete question]
Andy is incorrect because of the following.
Filling the empty boxes with any real numbers does not guarantee that the expression will be a polynomial.
For instance, if the expression is completed as thus:
(5x⁴ + 4x³)(4x^(2.7981) - 6) = A
This expression is not a polynomial because all powers of x must be non negative and it must be an integer.
So, Andy's statement is incorrect
Answer:
