Answer:
c. Mode
Step-by-step explanation:
Mean is the average obtained by adding all values and then dividing by the size of the values. Here, adding A and B etc is not clear.
Median is the middle value of a set of numeric values. To find a median, values should be sort-able from smallest to the largest. If there is no unique middle value, then the average of the middle values has to be taken. Here, average of the two different grades is not clear.
Mode is the value that occurs most often. Clearly C occurs most often.
Mid-range value is the mean of the difference between largest value and the smallest value. Here, difference between A and F is not clear.
Mean,median,Mid-range are applied to numeric values where mode is also suitable for categorical values.
Therefore, the most appropriate measure of central tendency for the data described is mode

Answer:
The first zero after decimal point and 4 only
Step-by-step explanation:
Despite having 5 decimal points, the rules of significant figures dictate that unless there is a digit other than zero after, the only significant numbers are those that come before zero. For this case, the significant digits are only 0.04 but if it was 0.0400005 then all the other zeros would have also be considered significant.
Answer:
=10x2−8
Step-by-step explanation:
4(x2−5)+2(3x2+6)
Distribute:
=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)
=4x2+−20+6x2+12
Combine Like Terms:
=4x2+−20+6x2+12
=(4x2+6x2)+(−20+12)
=10x2+−8
