Answer:
Dependent Event
Step-by-step explanation:
Assume that are 10 balls, such that:


If the balls are replaced after taken, the probability is:


This is referred to as independent event; because each selection do not affect the next or previous selection
However, if the balls are not replaced, the probability is:


We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.
This is referred to as independent event; because a selection affects the next selection
Answer:
|7 - n|
Step-by-step explanation:
Finding a difference means finding what that number is subtracted by another number, and then finding the absolute value of your result.
Assuming "a number" = n, the <u>difference</u><em> </em>of a number and 7 is |7 - n|
Answer:
C
Step-by-step explanation:
Using the pythagorean theorem, we can determine if these are right triangles or not.
equation: sqrt a^2+b^2=c
this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).
Work for C:
Squareroot of 32^2 + 24^2 = 40cm
I think it would be the second question!
Answer:
Step-by-step explanation:
B + 2C
= w + 10 + 2(-w - 1)
= w + 10 -2w - 2
= -w + 8
