Answer:
1
Step-by-step explanation:
Using the rule of logarithms
log x + log y ⇔ log(xy)
b = 1
Hence
log 5 + log 2 = log(5 × 2) = log 10 = 1
In order to get an average of 90, the student needs to get a score of 96.
The average can be found by summing up all the numbers in a data set and then dividing it by the number of characters in that dataset.
Assuming the average is 90, and that the score the student needs to get is x, the formula would be:
<em>Average = Sum of scores / Number of scores </em>
90 = (83 + 89 + 92 + x) / 4
90 x 4 = 264 + x
x = 360 - 264
x = 96
The student needs to get a score of 96 on the last exam.

Step-by-step explanation:
-64 1/3
disregard the negative sign for the moment...
to turn a mixed number into an improper fraction, take ur whole number (63) and multiply it by ur denominator (3) and u get (64 * 3) = 192....now add that to ur numerator (1) and u get (192 + 1) = 193...now put that over ur original denominator (3) and u get 193/3.....now put ur negative sign back....and u have - 193/3.....simplified form, does not reduce
