Answer:
5 ⁴/6
Step-by-step explanation:
12⅚ - 7⅙ = 5 ⁴/6
12 - 7 = 5
⅚. -. ⅙ = ⁴/6
HOPE THIS HELPS! (:
4/6 is a fraction, it just looks funky
Answer:
All real numbers.
Step-by-step explanation:
25-4x=15-3x+10-x
25-4x-(-3x)-(-x)=15+10
25-4x+3x+x=25
25-x+x=25
25=25
The answer is 4
This is because |-5+9|=|-4| which equals 4
Answer:
The correct option is (c).
Step-by-step explanation:
The complete question is:
The data for the student enrollment at a college in Southern California is:
Traditional Accelerated Total
Math-pathway Math-pathway
Female 1244 116 1360
Male 1054 54 1108
Total 2298 170 2468
We want to determine if the probability that a student enrolled in an accelerated math pathway is independent of whether the student is female. Which of the following pairs of probabilities is not a useful comparison?
a. 1360/2468 and 116/170
b. 170/2468 and 116/1360
c. 1360/2468 and 170/2468
Solution:
If two events <em>A</em> and <em>B</em> are independent then:

In this case we need to determine whether a student enrolled in an accelerated math pathway is independent of the student being a female.
Consider the following probabilities:

If the two events are independent then:
P (F|A) = P(F)
&
P (A|F) = P (A)
But what would not be a valid comparison is:
P (A) = P(F)
Thus, the correct option is (c).
