Answer:
do the rest urself
Step-by-step explanation:
-7 1/5= -36/5
-4 2/3= -14/3
-14/3-(-3
The answer is 361.
This is because you take 731 and subtract 9 and you get 722. Then you divide 722 by two and you get 361.
Hope this helped!!
Answer:
0.3913 = 39.13% probability that the student did not attend class regularly given that (s)he did not receive an above average grade
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Did not receive an above average grade.
Event B: Did not attend class regularly.
Probability of an student not receiving an above average grade:
100 - 40 = 60% of 70%(attend class regularly).
100 - 10 = 90% of 100 - 70 = 30%(do not attend class regularly).
So
Did not receive an above average grade and did not attend class regularly:
90% of 30%. So
Find the probability that the student did not attend class regularly given that (s)he did not receive an above average grade
0.3913 = 39.13% probability that the student did not attend class regularly given that (s)he did not receive an above average grade
Answer:
y = - x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (5, - 4) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = = = -
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - x - 1 ← equation in slope- intercept form
