Answer: 11 girls were not selected.
Step-by-step explanation:
First let's find out how many girls their were in total. In this case their are 23.
Let's subtract 12 from 23. That ends up to be 11. (<em>subtract 23 from 11 / 11 from 23)</em>
-23
-12
-------
11
40 ounces is 2.5 pounds because each pound is 16 ounces
Answer:
x = -1 + sqrt(78)/6
x = -1 - sqrt(78)/6
Step-by-step explanation:
Zeros are the x-values where the function is 0
f(x) = 0
6x² + 12x - 7 = 0
a = 6, b = 12, c = -7
Using Quadratic formula:
x = [-12 +- sqrt(12² - 4(6)(-7)]/2(6)
x = [-12 +- sqrt(312)]/12
x = [-12 + 2sqrt(78)]/12
x = -1 +- sqrt(78)/6
