Step-by-step explanation:
3) The equation of the graph is given by,
So, slope = 0 option A
4)The line passes through two given points in the fig. , (3,2) and (4,-1)
slope of the graph is given by
option D
5)
General equation in slope -intercept form
where, m is the slope and c is the y-intercept
Here, in this case m= -1
option C
6)
slope of the graph = 1
option C
He enlarged shape B by 300%

Answer:
Point estimate for the population variance = 3.92 * .
Step-by-step explanation:
We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;
X X -
1.13 1.13 - 1.188 = -0.058 3.364 *
1.15 1.15 - 1.188 = -0.038 1.444 *
1.15 1.15 - 1.188 = -0.038 1.444 *
1.24 1.24 - 1.188 = 0.052 2.704 *
1.27 1.27 - 1.188 = 0.082 <u> 6.724 * </u><u> </u>
<u>= 0.01568 </u>
Firstly, Mean of above data, = = = 1.188
Point estimate of Population Variance = Sample variance
= = = 3.92 * .
Therefore, point estimate for the population variance = 3.92 * .
