Answer:
87 points
Step-by-step explanation:
lets take "x" as the avg test scores of the past 6 tests
so
since their are 6 tests, we would represent the 6 tests as "6x"
to find average we need to add all numbers, and divide by the number of numbers
so since the final exam counts as two tests we need to add "99" twice
so
(6x+99+99)/8=90
multiply by "8" on bots sides and add 99 and 99 together
6x+198=720
subtract 198
6x=522
divide by 6
x=87
hope this helps
Answer: The boundaries of 9 pounds are;
8.5 – 9.5 pounds
Step-by-step explanation: Method used to find the boundaries.
The boundaries of an indicated value are the upper and lower bounds of
the value, which are the possible minimum or maximum values the
number may be before being rounded to the current value.
The given boundaries is = 9 pounds
The lowest possible value, 9 pounds can be before rounding up is 8.5 pounds.
Therefore; 8.5 pounds is the lower bound of 9 pounds.
The highest possible value of 9 pounds is 9.44999... pounds which is approximately 9.5 pounds
Therefore; The upper bound of 9 pounds is 9.5 pounds
Which gives;
The boundaries of 9 pounds are;
8.5 – 9.5 pounds
