Answer:
y = -6, perpendicular
Step-by-step explanation:
You can use the points to find the slope of the line:
Then, using point-slope form, choose one set of coordinates to use for y1 and x1:
Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.
======================================================
Explanation:
Count the number of times you divide by two and we have five occurrences of this. So there five rounds overall.
To get the total number of games played, we add up the quotients
16+8+4+2+1 = 31
----------------
Or as a shortcut we can simply subtract off 1 since 1+2+4+...+2^n = 2^(n+1)-1
We can write that rule as
which is equivalent to
The best prediction of the height of a student with an arm span of 143 cm is 143 cm
Step-by-step explanation:
The missing graph is attached
The graph below shows the heights and arm spans of students in
a classroom
We need to find the height of a student with an arm span of 143 cm
∵ The graph does not contain the value of the given arm span
∴ We will use the line best fit (sold line in the attached graph) to find
the best predication of the height
∵ The line passes through points (150 , 150) and (160 , 160)
- The x-coordinates are equal the y-coordinate
∴ The equation of the line is y = x
∵ The arm span of a student is 143 cm
∵ y represents the arm span of a student
∴ y = 143
- Substitute the value of y in the equation of the line best fit
∵ y = x
∴ 143 = x
∵ x represents the height of a student
∴ The height of the student is 143 cm
The best prediction of the height of a student with an arm span of 143 cm is 143 cm
