Answer:
positive association
linear association
Step-by-step explanation:
It is said that two variables A and B are related when the distribution of the values of one of the two variables differs according to the values of the other.
That is, when variable A grows then variable B also grows. This is known as positive correlation
When variable A grows then variable B decreases. This is known as negative correlation.
In the scatter plot you may notice that when variable A increases then variable B also increases, in an approximately linear relationship. Therefore it can be said that there is a positive and linear association.
The answer is the fourth and fifth option.
Answer:
<u>1/ 130 is the probability that they are the 4 oldest people in the group. </u>
Step-by-step explanation:
In the question, we are given; group of 11 people, 4 are selected randomly, find probability they are the 4 oldest people from the group
P(O)= <em>favorable number of outcomes / total number of outcomes </em>
<h3>= 1 / 11C4</h3>
= 11! / (11-4)! 4!
= 7! *4! / 11!
=1/ 130
<em>Therefore, 1 / 130 is the probability that they are the 4 oldest people in the group. </em>

Answer:
To keep the same volume, the designer needs to decrease the height of the vase by 20%
Step-by-step explanation:
Volume of cylinder formula is 
Area of base is
, if this area is increased by 25%, the new area of base would be:

Since volume would be same, we can make the height as:

Thus, we can see that the height needs to be divided by 1.25, which we can write in fractional form as:

Thus, height needs to be
of original (or 80% of original)
