Answer:
The probability that a student passed the test given that they did not complete the assignment is .
Step-by-step explanation:
The probability of an event <em>E</em> is the ratio of the number of favorable outcomes <em>n</em> (E) to the total number of outcomes <em>N</em>.
The union of two events is:
The intersection of the complements of two events is:
The condition probability of an event given that another event has already occurred is:
Denote the events as follows:
<em>A</em> = students who passed the test
<em>B</em> = students who completed the assignment
Given:
N = 27
n (A) = 17
n (B) = 22
= 3
Compute the value of P (<em>A</em> ∪ <em>B</em>) as follows:
Compute the value of P (A ∩ B) as follows:
Compute the value of P (A | B) as follows:
Thus, the probability that a student passed the test given that they did not complete the assignment is .

Step-by-step explanation:
3y + 11 + 7x - 30 + 5x + 14
3y + 12x - 5
3y = -12x + 5
y = (-12x + 5)/3
x = (3y - 5)/-12
hope this helps
Answer:
d = 8.6
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 5^2 = c^2
49 + 25 = c^2
74 = c^2
Now you take the square root of 74 and c^2
If you put the square root of 74 in a calculator you get about 8.6
So c = 8.6 or d = 8.6
