Answer:
Mary is times heavier than her sister
Step-by-step explanation:
Mary's Weight = n
Sister's Weight = n - 15
To find how many times mary is heavier, we need to multiply "that many time" [let it be x] with sister's weight to get Mary's weight.
<u>e.g. </u>If someone weighs 100 and another person 50, 50 * 2 = 100, thus, 100 kg person is 2 times heaving. We do same for this:
(n - 15) * x = n
x = n/(n - 15)
Answer:
No
Step-by-step explanation:
<u>Step 1: Determine if linear </u>
It is not linear because it has the x variable to the second power which makes the line bend and turns into a parabola. A linear line would have the x to the first power or just x.
Answer: No

Answer:
Step-by-step explanation:
Sample Space for the Cube, A={1,2,3,4,5,6}
n(A)=6
Even Numbers in A={2,4,6}
Sample Space for the Cards, B={1,2,3,4,5}
n(B)=5
Even numbers in the card,B= {2,4}
The two events are INDEPENDENT Events as the outcome of the cube does not affect the card picked, therefore:
P(A and B)=P(A) X P(B)
