Answer:
g = 
Step-by-step explanation:
Given
t = v + 
Multiply through by g to clear the fraction
tg = vg + k ( subtract vg from both sides )
tg - vg = k ← factor out g from each term on the left side
g(t - v) = k ← divide both sides by (t - v)
g = 
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
