leva [86]2 years ago
3 0

Answer:

13 31/40

Step-by-step explanation:

1) convert both fractions into improper fractions (you can do so by multiplying the whole number by the denominator/bottom part and then adding that to the numerator/top part)

by doing this, you will get 51/8 and 37/5

2) since you need a common denominator in order to add the two fractions, multiply the top and bottom of 51/8 by 5. Then, multiply the top and bottom of 37/5 by 8.

3) Then, add the top numbers together and your answer will be 551/40, which can be simplified into 13 31/40

I hope this helps!

Select all of the features that define a bivariate normal distribution.

<em>(this means that we select only those that are properties of the bivariate normal distribution)</em>

A. Bell-shaped probability distribution in two dimensions rather than one

<em>TRUE  because any combination of the two is still normal Z(x,y)=aX+bY</em>

B. A relationship between X and Y that is not linear

<em>TRUE The contours of the distribution are ellipses.</em>

C. The presence of outliers

<em>FALSE possible, but not always.</em>

D. Either X or Y has a decidedly skewed distribution

<em>FALSE normal distributions are symmetric</em>

E. A relationship between X and Y that is linear

<em>FALSE see answer to B</em>

F. A cloud of points that is funnel shaped (wider at one end than the other)

<em>FALSE normal distributions are symmetric</em>

G. The frequency distributions of X andY separately are normal

TRUE For example, in <em>Z(x,y)=aX+bY, putting a or b=0 means that X and Y separately are normal.</em>
