Answer:
no
Step-by-step explanation:
80 * 5/8 will give you how many are thoroughbreds.
80 * 5/8 = 50
Now subtract this from all of the horses.
80 - 50 = 30.
There are 30 quarter horses.
OR If 5/8 of the horses are thoroughbreds, then 3/8 are quarter horses.
80 * 3/8 = 30.
Answer:
3/7 and 4/14
Step-by-step explanation:
a) 3/7 is not an equivalent of 6/21 because when you multiply the numerator and the denominator by 2 you get: 6/14
b) 4/14 is not an equivalent
This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity.
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>
