Answer: 7/19</h3>
Explanation:
There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total
The probability of selecting blue is therefore 7/19
We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.
To find the median cancel out numbers on both sides, until one is left in the middle and if there are two in the middle add them up and divide by two.
So in this case the median is
53+78
131 / 2
65.5
<span>solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.</span>
Answer:
B. 17
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
7 (7 + x) = 8 (13 + 8)
49 +7x = 8*21
7x = 168 - 49
7x = 119
x = 119/7
x = 17
