The inquiry requests that I calculate and formulate the parametric representation for the specified surface and the plane that includes the vector i - j and j - k, originating from the origin. Based on my development of this, the equation for the surface in parametric form can be expressed as S:(U,V,-U-V). I hope this information is useful.
Answer:
The original cost amounts to $10
Step-by-step explanation:
Let us denote the cost as x
where Price = x + (0.5x) = 1.50x
Now, the price after reduction is 20% of 1.50x
which is 0.3x 
This leads to the equation 1.50x - 0.3x = 12
resulting in 1.2x = 12
which gives us x = 10
thus, the cost is $10
Answer:
Two thirds of a straight angle is 120°
Explanation:
First, we define a straight angle:
A straight angle measures 180°
Now, we need to find two thirds of that straight angle
To compute the fraction, multiply the straight angle's measurement by 
Thus:
of a straight angle = 
degrees

Answer: 0.31
Step-by-step explanation:
Let A signifies the event of the Tampa Bay Buccaneers scoring a touchdown on their initial drive while B signifies the occurrence of their defense achieving 3 or more sacks during the game.
Given: P(A)=0.14 P(B) = 0.31 P(A or B)=0.14
Formula: P(A and B)= P(A) + P(B) - P(A or B)
Now, we calculate the probability of both scoring a touchdown on the initial drive and achieving 3 or more sacks in the game as follows:-
P(A and B)= 0.14 + 0.31 - 0.14=0.31
Therefore, the required probability is: 0.31
