Answer:
A quick comparison of the sample variances suggests that the population variances <u><em>are same or almost equal.</em></u>
Step-by-step explanation:
The populations from which two samples are drawn are normally distributed.
The variable used to predict another variable is called an independent variable.
F- distribution is used for the test of two sample hypotheses of variances.
If two populations have equal variances then the test Statistic is nearly equal to 1.
<em>t= s²₁/s²₂i</em>
<em />
As the variances are almost or nearly equal the test statistic would be almost equal to 1.

In geometry, the three undefined terms are: the point, the plane and the straight line.
Since all the given graphs represent lines,we will need to choose the straight line among them.
Straight line is a line that has no start and no end.
From the choices:
Figures a and c are rays
figure b is a line segment
figure d is a straight line
Therefore, the correct choice is: D
Answer:
y>=x+1
Step-by-step explanation:
it will be y>= x+1 bcz the shaded area shows a straight line rather than a dotted line which means the line is part of the shaded region. so that's why y>=x+1
