Answer:
The percentage is 83%
Step-by-step explanation:
Generally R-Sq is known as the coefficient of determination and from the question the value is 83% and this R-Sq defines the total variation in test scores can be explained by the linear relationship between years of study and test scores
So 83 % of the total variation in test scores is unexplained by the linear relationship between years of study and test scores
Answer:
y = (4/3)x
Step-by-step explanation:
Two points on the line are the origen (0, 0) and the given (9, 12).
Starting at the origin and moving to (9, 12), we see the change in x being 9 and that in y being 12. Thus, the slope of the line through these two points is m = rise/run = 12/9 = 4/3.
Thus the equation of the line in slope-intercept form is y = (4/3)x + 0, or
just y = (4/3)x
Answer:
no
Step-by-step explanation:
Assuming the wall makes a 90-degree angle with the ground, the ladder is the hypotenuse of a right triangle whose legs are the ground distance, the wall height, and whose hypotenuse is the ladder length.
The hypotenuse of a right triangle must be longer than either side. If one side is length 13 and one side is length 5, the hypotenuse must be about 13.93. A 13-ft ladder will not do.
Answer:
Here the answer is
.
Step-by-step explanation:
Here the given is:
C = Parents send children to school.
E = Employees go to work.
P = The public will panic.
Q = Infected people are quarantined.
S = There is a swine flu epidemic
Now the given statement is given as follows,
(if S then Q) and P and (if S then (not C) and (not E))
So this can be written in symbolic form as:
