Answer:
y = x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
f(x) = - 2x + 1 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, then
y = x + c
the line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = x + 5 ← equation of perpendicular line
Answer:
A. -1.6; not significant
Step-by-step explanation:
The z-score of a data set that is normally distributed with a mean of and a standard deviation of
, is given by:
.
From the question, the test score is: , the mean is
, and the standard deviation is
.
We just have to plug these values into the above formula to obtain:
.
This simplifies to: .
.
We can see that the z-score falls within two standard deviations of the mean.
Since the value is not significant.
The correct answer is A. -1.6; not significant
