Answer: 72.5
Step-by-step explanation:
The average of 2 points is the midpoint so if I add 70 and 75 to get 145 and divide by the number of numbers which is 2 I get 72.5
This is the way you write 300,022,000
If the weight is lowered by 25% it is the same as taking 75% of the original weight.
0.75x = 33

Answer: A) y = -3</h3>
Explanation:
The general sine equation is
y = A*sin(B(x-C)) + D
where the D variable directly determines the midline. In this case, D = -3, so that corresponds to a midline of y = -3
The sine curve oscillates going up and down, passing through this middle horizontal line infinitely many times. See the graph below.
