Average of 2 numbers is 40
so total = 2 x 40 = 80
300 - 80 = 220
average of remaining 10 numbers = 220/10 = 22
answer
B) 22
The value of n such that the number n and -3/4 are additive inverses is 3/4
<h3>How to determine the value of n?</h3>
The statement is given as:
The number n and -3/4 are additive inverses
The above statement means that
n = -1 * -3/4 --- by the definition of additive inverses
Next, we evaluate the product of -1 and -3/4
n = 3/4
Hence, the value of n such that the number n and -3/4 are additive inverses is 3/4

A = 5/6(B + C)
multiply 6 on both sides
6A = 5(B + C)
divide 5 from both sides
6A/5 = B + C
subtract B from both sides
6A/5 - B = C
The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π
<h3>Midline, Amplitude and Period</h3>
The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1
The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4
Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
