What would be the question????
Answer:
Probability that student has a good grade = 0.525
Step-by-step explanation:
Given
Chances of earning a good grade when assignments are done on time = 0.80
Chances of earning a good grade when assignments are finished during class or late = 0.30
Chances of earning a good grade when assignments are not done at all = 0.05
% of students who completed assignment on time = 0.50
% of students who completed assignment during class = 0.40
% of students who did not completed assignment at all = 0.10
Probability that student has a good grade
= (0.80 *0.50) + (0.30*0.40) + (0.05*0.10)
= 0.525
The fraction of a whole pan of lasagna that tom ate if he started with 7/8 of a pan is 1/8
<h3>How to determine the fraction</h3>
From the information given, we have that:
Tom started with 7/ 8 of the pan
Let the original size of the pan be 1
The fraction of the whole pan he ate is:
= Original size - size of what Tom ate
= 1 - 7/8
Find the LCM
=8 - 7 / 8
= 1/ 8
Thus, the fraction of a whole pan of lasagna that tom ate if he started with 7/8 of a pan is 1/8

Answer:
A. 0.5< t < 0.75
Step-by-step explanation:
We can use the relation ...
time = distance / speed
to find the number of hours it took Johanna to walk around the lake.
time = (2 mi)/(3 mi/h) = 2/3 h
2/3 is between 1/2 and 3/4, so the first answer choice describes the interval containing Johanna's time:
0.5 < t < 0.75
