Answer:
23/30 are blue balloons. 23/30 = 76.7 = 0.767. I would say that 0.767 is the answer!
Total students 5+16+42+22+5 = 90
0-1's probability is 5 / 90 = 5.5% about
2-3's probability is 16 / 90 = 17.7% about
4-5's probability is 42 / 60 = 46.6% about
6-7's probability is 22 / 90 = 24.4% about
8+'s probability is 5 / 90 = 5.5% about
(percentages not rounded, just cut off at the first decimal)
Answer:
6 trips
Step-by-step explanation:
12 divided by 4 equals 3
18 divided by 3 equal 6
she will have to take six trips to drive 18 kilometers.
<span>-8(4 + 9x) = 7(-2 -11x)
STEP 1: Simplify both sides of the equation.

Sure! Let me help you on this one, Adrien.
There are 18 marbles in the bag, 3 of them being blue. Let's put this in a ratio.
3 out of 18.
Simplify.
1 out of 6.
This means that statistically speaking, if you pull out 6 marbles, one of them will be blue.
