Answer:
1. quadratic
2. quadratic
3. linear
4. quadratic
Step-by-step explanation:
In the picture attached, the scatter plots are shown.
The differences between these correlations are:
- linear
: makes a straight line
- quadratic: makes a ∩ or ∪
- exponential: rises or falls quickly in one direction
In plot 1, 2 and 4, we can see that y-values decrease at first and then they increase. This is a feature of quadratic correlation
In plot 3, we can see that y-values increase uniformly as x-values increase.This is a feature of linear correlation
Answer:
The graph shifts 3 units down.
Step-by-step explanation:
From the options presented, only figure number 2 or the one that looks like a cross has a rotation symmetry.
<h3>What is rotation symetry?</h3>
This type of symmetry implies that when a figure is rotated it matches its original shape. An example of this is the circle.
<h3>Which figures have rotation symmetry?</h3>
From the options presented, only the cross has this symetry because its side are equal and this means you can rotate it and it will look the same.

Answer:
0.71%
Step-by-step explanation:
Given that a normally distributed set of data has a mean of 102 and a standard deviation of 20.
Let X be the random variable
Then X is N(102, 20)
We can convert this into standard Z score by
We are to find the probability and after wards percentage of scores in the data set expected to be below a score of 151.
First let us find out probability using std normal table
P(X<151) = 
We can convert this into percent as muliplying by 100
percent of scores in the data set expected to be below a score of 151.
=0.71%
