Answer:
4/5
Step-by-step explanation:
There are 2 whites out of a total of 10 marbles.
The chances of drawing a white is thus 2/10, or 1/5.
The chances of drawing a non-white marble is the complement of this 1/5, or 1 - 1/5 = 4/5.
Answer: 4/5
There are 10 marbles in the bag, two of them being white. so 2/10 are white while 8/10 are not. So 8 out of ten pulls theoretically wouldn't be white. simplify 8/10 to 4/5
the area of a triangle is
baseline × height / 2
in our case
baseline × 5 / 2 = 20 in²
baseline × 5 = 40
baseline = 8 in
7a-7
2a+2−3a−5+a−4+7a.
Combine like terms
2a-3a+a+7a+2-5-4
0 (zero)
