Answer:
5/14 ≈ 35.7%
Step-by-step explanation:
(12 +6) = 18 of the 28 students earned an A or a B. So, the experimental probability that a student did not earn that grade is ...
p(<B) = (28 -18)/28 = 10/28
p(<B) = 5/14 ≈ 35.7%
Answer:

Step-by-step explanation:
The graph is a series of horizontal lines. A solid dot goes wherever there is an "or equal to" symbol in the inequality. An open dot goes where the point is not included in the function definition (but nearby points are).
X+10>50
=x>40
Any number higher than 40 satisfies this condition.
They are equal.
(a/b)^2 = (a/b)(a/b) = (a*a)/(b*b) = a^2/b^2
Answer:
it is 240
Step-by-step explanation:
put in equation and solve
2/3t+10=170
t=240
