Step-by-step explanation:
When you use "and" you multiply the probabilities
Probability to get a 4 is 1/6
Probability to get a 5 is 1/6

Answer:
A student with GPA of 2.15 worked 47.8 hours per week.
Step-by-step explanation:
To find the numbers of hours worked when the GPA is 2.15, we solve the equation when or:
which can be rewritten as (<em>by subtracting 2.15 from both sides)</em>
<em /><em>.</em>
We solve this using the quadratic equation which says, for ,
in our case
,
therefore, we have
and since only the positive solution applies to the real word, we choose , and therefore, a student with GPA of 2.15 worked 47.8 hours per week.

Answer:
im in 8th grade and can't do that math
Step-by-step explanation:
i dont understannnddd
Area = 1/2(base x height)
1/2(10(x + 4)) <= 56
5(x + 4) <= 56
x + 4 <= 11.2
x <= 11.2 - 4
x <= 7.2
Therefore, possible integer values of x are {1, 2, 3, 4, 5, 6, 7}
