Answer:
2/27
Explanation:
The two events, drawing a blue marble out of each bag, are independent. This means to find the probability of both occurring, we multiply them.
In the first bag, there are 5 blue marbles out of 15 total. This makes the probability 5/15, or 1/3.
In the second bag, there are 2 blue marbles out of 9 total. This makes the probability 2/9.
Together, the probability of both events happening are:
1/3(2/9) = 2/27
From the given above, the point that still needs to be incurred by the group is calculated by subtracting 424 points from 1000. This as shown below,
n = 1000 - 424 = 576
If we are to determine the number of points each game, we divide 576 by 9. That is,
x = 576 / 9 = 64
<em>ANSWER: 64 points/ game</em>
answer:
slope: -2/3
step-by-step explanation:
y=mx+b
m represents the slope, and b the y-intercept.
rearrange: 9x= -6y+18
---> -6y= -9x-18
divide all terms by -6.
-6y/-6= -9/-6x-18/-6
y= 3/2x+3 (slope/intercept form)
m= 3/2
---> 1/3/2= -2/3
Answer:
Step-by-step explanation:
To express a number as a percentage, you need to write it as a ratio with denominator 100.
We know that ratios have different forms they can be written into, for example, all the following are equivalent:
So, since 43 students out of 860 are sick, the ratio of sick students is
and we want to express this as a ratio with denominator 100, so we have
So, if we solve for x, we have
So, 5% of students is sick.
