Answer:
Step-by-step explanation:
Given that the hartford insurance company has hired you to poll a sample of adults about their car purchases.
Here the insurance company is using convenience sampling to select customers so they resorted to taking the names from telephone directories.
But this may not be reliable since persons owning cars need not have telephones and similarly persons having telephones need not own cars
Owning a car and name appearing in telephone directory need not be associated at all
So taking random sample of names from telephone directories may not give the required accurate result since here sample cannot be assumed to represent the population of car owners.
perimeter =QR+RS+ST+TU+UQ =26.1
RQ = 5.39
RS = 4.47
ST = 3.61
TU = 4.12
UQ = 8.54
Answer:
3/5
Step-by-step explanation:
ir would be 6/10 but simplified it would be 3/5
Answer:
(13,-23)
Step-by-step explanation:
Comparing the image coordinates to the transformation rule, you see that ...
(x -4, y +15) = (9, -8)
Adding (4, -15) to these coordinates, we get ...
(x -4, y +15) +(4, -15) = (9, -8) +(4, -15)
(x-4+4, y+15-15) = (9+4, -8-15)
(x, y) = (13, -23) . . . . coordinates of D
Answer:
Step-by-step explanation:
The question we have at hand is, in other words,
- where we have to solve for the value of 
If we have to isolate here, then we would have to take the inverse of the following matrix ...
... so that it should be as follows ... 
Therefore, we can conclude that the equation as to solve for " " will be the following,
- First find the 2 x 2 matrix inverse of the first portion,
= 
= 
= 
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
,
- Simplifying this, we should get ...
... which is our solution.
