Step-by-step explanation:
The equation for the best fitting line is y = 2.599x + 105.08. When x is set to 20, the predicted height becomes y = 157.06. However, the actual height recorded is 160 cm, therefore, the residual is calculated as:
160 cm − 157.06 cm = 2.94 cm
Response:
Based on the anticipated number of individuals completing the form to claim the refund, the company ought to foresee its net profit decreasing to:
- $174.6 per computer tablet.
Detailed explanation:
Initially, the profit per tablet is $180, but after initiating the rebate program, it is expected that 18% of purchasers will fill out the forms and obtain the VISA card, which will lower the profit as demonstrated below:
- Calculation of the reduced benefit for 18% of computer tablets = original benefit - refund amount.
- Reduced benefit for 18% of tablets = $180 - $30 = $150
From here, we find that 18% of tablets will yield a benefit of $150, while the other 82% will maintain a benefit of $180. To ascertain an overall figure for the benefit, we must compute it as follows:
- Total benefit = Percentage of reimbursed tablets * Benefit of reimbursed tablets + Percentage of non-reimbursed tablets * Benefit of non-reimbursed tablets.
- Overall profit = 18% * 150 + 82% * 180
- Overall profit = $174.6
Thus, after the $30 rebate on 18% of the tablets, the total benefit amounts to $174.6.
The co-payment for his doctor visits totals:
10 x 18 = $180.
For his physical therapy sessions, the co-payment amounts to:
10 x 20% x 150 = $300.
When you sum both co-payments, it totals $480.
The numerical variables in this scenario include:
A. Speed
D. GForce
E. Height
G. Duration
H. Numinversions
J. Length
In detail:
A method to distinguish quantitative from qualitative variables is assessing if mathematical calculations on these variables are relevant.
When it is applicable, it indicates a quantitative variable.
For instance, even though binary variables can be expressed as 0 and 1, they are still considered qualitative variables.
The numerical variables in this case are:
A. Speed
D. GForce
E. Height
G. Duration
H. Numinversions
J. Length
They will all be expressed in numerical terms where mathematical operations are meaningful.
