Answer:
Step-by-step explanation:
From the given information:
The mean
The sample variance is as follows:
The complementary angle of 12 degrees, is 78 degrees.
Complementary angles are angles that when added together have an end result of 90 degrees. So, to find the answer, simply subtract 12 from 90. Thus making the answer 78 degrees.

Answer:
£14.85
Step-by-step explanation:
The total number of tiles needed
= 5 × 3
= 15
∴ The total cost of the tiles
= £0.99 × 15
= £14.85
Answer:
You're trying to find the equation for a portion of a line. The first thing I notice is that the slope is negative. The slope is -1/2 and the y-intercept would be -3. That means the answer is either A or B. X is greater than -2, so the answer is B.
I hope that helps.
Answer:
In contrast, linear equations can describe values that are negative, zero or positive. As a result, the range of an absolute value function is zero and all positive numbers, while the range of a linear equation is all numbers.
The function inside the absolute value is NOT linear, therefore the graph contains curves.
