Find the academic calendar, and then answer: How many days after the end of the course are the final grades published? Select one:
a. 12 days
b. 7 days
c. 14 days
<em>d. 3 days</em>
Answer:
<u>7 days</u>
<u>Step-by-step explanation:</u>
Take note that under standard practice and based on the information available that it would take up to 7 days after the end of a course for the final grades to be published.
Thus, the correct option is 7 days.
Answer:
(6,0)
Step-by-step explanation:
Given equations are:
\[x - 4y = 6\] -------------------- (1)
\[2x + 2y = 12\] -------------------- (2)
Multiplying (1) by 2 :
\[2x - 8y = 12\] -------------------- (3)
Calculating (2) - (3) :
\[2x + 2y -2x + 8y = 12 - 12\]
=> \[10y =0\]
=> \[y = 0\]
Substituting the value of y in (1):
\[ x = 6 \]
So the required solution of the system of equations is x=6,y=0. This can be alternatively expressed in coordinate notation as (6,0).
Answer:4√(13)
Step-by-step explanation:
Adjacent=12
Opposite=8
Hypotenuse=√((adjacent)^2+(opposite)^2)
hypotenuse=√(12^2+8^2)
Hypotenuse=√(12x12+8x8)
Hypotenuse=√(144+64)
Hypotenuse=√(208)
Hypotenuse=√(16x13)
hypotenuse=√(16) x √(13)
Hypotenuse=4 x √(13)
Hypotenuse=4√(13)
The ratio of false positives to false negatives is (d) 3.5
<h3>How to determine the ratio?</h3>
The table of values is given as
Activates. Does not activate Row Totals
Lightning in area 88% 2% 90%
No lightning in area 7% 3% 10%
Column Totals 95% 5% 100%
The false negative is when there is lighting and it does not activate
So, we have
False negative = 2%
The false positive is when there is no lighting and it activates
So, we have
False positive = 7%
When represented as ratio, we have
Ratio = 7% : 2%
So, we have
Ratio = 7 : 2
This gives
Ratio = 7/2
Evaluate
Ratio = 3.5
Hence, the ratio is (d) 3.5
