The probability that the marble she chooses is not blue can be solve in two ways.
first way: is to solve the probability of red and yellow marbles, so that is the probability of not getting blue
P = 6 + 8 / 6 + 8 + 18P = 7/16
2nd way: is to solve the null of blue or 1 minus the probabilty of choosing blue marble
P = 1 - (18 / 6 + 8 + 18)P = 1 - ( 9 / 16)P = 7/16
Answer:
3952.8$
Step-by-step explanation:
61$ : 100 = x : 60% (since it is 40% off, the remaining is 60% of the price)
100x : 61 x 60
100x : 3360
3360 divided by 100
x = 36.6
36.6 : 100% = x 108%
100x : 36.6 x 108
x = 3952.8
3952.8 divided by 100
39.528
Answer:
<em>A)</em> The answer is D, 8a + 5
4a + 5 + 4a
we simplify this expression(combine like terms):
group them first;
(4a + 4a) + 5
8a + 5
<em>B)</em> 2c + 6 + 3c - 4
simplify this expression (combine like terms):
group them first;
(2c + 3c) + (6 - 4)
5c + 2
