Answer:
The domain of P is given by,
{n | n ∈ N, 2 ≤ n ≤ 12}
Step-by-step explanation:
A perfect die is perfectly cubic in shape with one of the integers 1,2,3,4, 5 or 6 in each of it's 6 faces and the digits on any two faces are different.
Now, two dice are rolled and P(n) models the probability of the event that the sum on the faces of the two dice is n.
Hence, the domain of P is given by,
{n | n ∈ N, 2 ≤ n ≤ 12}
All you have to do is substitute all the Xs to and get a final y output.
for example:
if we take the number x is -1 all you do is:
y=-4(-1)+2
y=4+2
y=6
thats the first one done
Answer:
60/220
Step-by-step explanation:
we use combination,


then, all divided by,


Answer:
9.63 metres
Step-by-step explanation:
The base to height ratio =12:1
From the given ramp, Base to Height Ratio =Base:0.8
Therefore:
12:1=Base:0.8

To find the length of the ramp, we apply Pythagoras theorem in the right triangle formed.
Length of the ramp ,l
