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
Answer is A
Explanation
It states the stapes
The number line that represents |x + 4| = 2 has a solution of -2 and another solution of - 6
<h3>How to determine the number line?</h3>
The equation is given as:
|x + 4| = 2
Remove the absolute value bracket
x + 4 = 2 or x + 4 = -2
Subtract 4 from both sides
x = -2 or x = -6
Hence, the number line that represents |x + 4| = 2 has a solution of -2 and another solution of - 6

Answer:
Option 1
Step-by-step explanation:
-4x+6y-5z=60
for x-int, solve for x when y=0, z=0
-4x+6(0)-5(0)=60
x=-15 (-15, 0,0)
for y-int, solve for y when x=0, z=0
y=10 (0, 10,0)
for z-int, solve for z when x=0, y=0
z=-12 (0, 0,-12)
