x = 1.486
y = 8.929
EXY- nXY 193.3- (149.486 -1.486)
Calculated using the formula b =9 = 31 .94 - (14 *1. 486 *1 A86 ) =7.31405
X2 - 7.31405
Calculated using Excel a =Y - bX = 8.929 - 7.31405 *1.486 = -1.938017
Y = a + bx = -1.93802 + 7.31405x
c. Using the formula
Y = a + bx = -1.58678 + 7.033058x
= 14.8843

Answer:
$213451.2
Explanation:
9.8% of the savings monthly
9.8/100 X 360
35.28
total monthly savings = 360 + 35.28
= 395.28
So, for the next 45 years, total amount in account
= 45 X 12
= 540 months
Total account for 45 years
= 540 X 395.28
= $213451.2
Answer:
Task identification/identity, feedback
Explanation:
Task identification, simply put, is the ability of an employee to understand his or job and its requirements.
Feedback on the other hand can also be simply said to be the response that is derived from a product use by consumers. Feedback helps to tell whether a product or firm is doing the right thing or there is room for improvement in its products or firm practices.
In the case of Anya, her job involves a great deal of task/job identification/identity as she has to be capable of envisioning the specifications of clients as well as requesting for feedback to ensure that she is doing exactly what the client wants.
Cheers.
