Answer:
12-157.5 13-6ft
Step-by-step explanation:
the first one just look up 65% of 450 and minus the number you get by 450
the second one do the butterfly method
the heights on top and shadows on bottom
12x=72
x=6

Option B:
The linear equation that best describes the model is y = 40x + 800.
Solution:
Take two points which exactly on the line.
Let the points are (0, 800) and (10, 1200).
Slope of the line:
m = 40
y-intercept of the line is where the line crosses at y-axis.
y-intercept (b) = 800
Equation of a line:
y = mx + b
y = 40x + 800
The linear equation that best describes the model is y = 40x + 800.
Option B is the correct answer.
The required linear equation is given by y=10x + 15
The data collected by Harvard Business School plots the linear relationship of business startup success vs. Time.
The statistic is the study of mathematics which deal with relations between comprehensive data.
As clearly, points represents on graph startup success vs Time
part of a straight line
so we take two points on graph at (1,25), (2,35)
now equation of line
=
Thus, The required expression is given by y=10x + 15 which show the relation ship between startup success Vs time
