If students get their assignments done on time there is an 80% chance of earning a good grade in the class. If the assignments are finished during class or late then there is only a 30% chance of earning a good grade in the class. If the assignments are not done at all then there is only a 5% chance of earning a good grade in the class. In a certain class, 50% of the students have the assignments completed on time, 40% finish during class, and 10% do not do their assignments. If a student from this class is selected at random, what is the probability that student has a good grade?
Answers
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

find the circumfernce of the circle Use 3.14 for
Answers
Answer: To find the circumference of a circle, use the formula, 2(3.14)(r) (r is the radius, and if it gives the diameter, divide the diameter by 2 [to get the radius]). To find the actual circumference of the circle, multiply 2 and 3.14, becoming 6.28. Then, multiply 6.28 by whatever the radius is. Hope you find this useful!
Note: I am going based on no given picture and measurements of the circle, the other person that answered is, also, correct, and you could multiply the first two numbers (and then multiply the other number by the answer you received) OR multiply the first number, being 2, by the radius (and multiply that answer by the number of 3.14). For an example, the radius=10 units. You could either do 2x10=20, then 20x3.14=62.8 units^2 or multiply 3.14x2=6.28 units, then multiply 6.28 by 10, which is 62.8 units^2.

If 35 people going to the movie bought popcorn and that was 20% of all the people at the movie how many people were at the movie
Answers
Answer:
Im pretty sure it would be 700 but im most likely wrong.
If 35 people is 20% of all people, we can assume that 35 is 1/5 of all the people at the movie since 20% is 1/5 of 100%
All we have to do is multiple 35 by five.
I can prove my answer by dividing 175 by 5 which would give me 20% of 175

TOMATI
Soup
12 cm
7 cm
Answers
Answer:
462 cm³
Step-by-step explanation:
A can of soup has the shape of a cylinder
Volume of a cylinder = πr²h
π = 3.14
radius, r = diameter / 2
= 7cm / 2
= 3.5 cm
Height, h = 12 cm
Volume of a cylinder = πr²h
= 3.14 * (3.5)² * 12
= 3.14 * 12.25 * 13
= 461.58 cm³
Volume of the cylinder = 461.58 cm³
Approximately to the nearest cubic centimeter = 462 cm³

Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.
