Answer/Step-by-step explanation:
a. Using two points on the line (0, 2) and (4, 12), find the gradient:
Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5
Gradient = 2.5
b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.
i.e. 2.5 litres per second
c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.
Answer:
Domain is (8,7,6,5) and Range is (7,7,7,7)
Answer:
Step-by-step explanation:
Oh, this is a lot easier than you made it sound, lol.
This is the correct answer:
The table with the following:
X=6,7,9,11,13,14
Y=27,33,39,49,58,71
Lol, I didn't realize that was all this was.
Anyways, the table that matches that is correct, that's actually a bit obvious. The numbers you gave me are parameters, a limit. The numbers for x per y have to fall between those numbers listed.
When the two six-sided fair dice are rolled then we get total of 36 order pairs.
In the first question,
in which we have to find the probability that at least one number is odd and the sum of two numbers is even; for this question we get the total of 9 order pairs which are (1,1),(1,3),(1,5),(3,1),(3,3),(3,5),(5,1),(5,3),(5,5)
Probability= no. of order pairs that contain at least one number is odd and the sum of two numbers is even) / total no. of order pairs
P= 9/36
P=1/4
For the second question,
four order pairs which will fulfill the condition that exactly one number is 6 and the product of the two numbers is at most 15 are (1,6),(2,6),(6,1),(6,2)
So,
Probability= no. of order pairs that exactly one number is 6 and the product of the two numbers is at most 15/ total no. of order pairs
Probability= 4/36
P=1/9
