Let x = the next score
If (81 + 89 + 90 + 83 + 77 + x) ÷ 6 = 82
⇒ 420 + x = (82 × 6)
⇒ x = 492 - 420
x = 72
Thus to get an 82 average he need to get 72 on his next test.
Answer:
There are 14 problems worth 5 points and 15 problems worth 2 points.
Step-by-step explanation:
Hope this helped have a good day :)
The slope can be found by using the formula:
m

Where
m
is the slope and (
x

,
y

) and (
x

,
y

) are the two points on the line.
Substituting the values from the points in the problem gives:

Answer:
n=11
Step-by-step explanation:
This is a right angle, so the angles are complementary and have a sum of 90°.
