Answer:
76.7
Step-by-step explanation:
11.3(3) + 10.7(4) = __ + 42.8
Multiply values
33.9 + 42.8 = __ + 42.8
The missing value is 33.9!
42.8 + 33.9 = 76.7
The mean is the sum of all numbers divided by the number of numbers. We can set up an equation:

Where 'x' is the next quiz score she need. Solve for 'x'. Multiply 5 to both sides:

Add:

Subtract 322 to both sides:

So her next quiz score needs to be 73 in order to have a mean score of 79 on all her quizzes.
Unlikely? it would be 1 out of 52 chances
See diagram
so we got a right triangle
so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²
so the legs are 90 and 90
hytponuse is distance from home to 2nd
so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c

about 127ft
Answer:
Since The graph of linear equation 3x + 2y = 16 cuts y-axis
So
x = 0
The required point is (0,8)
