Answer:
convert 3 1/3 to an improper fraction
3*3 = 9
9+1 = 10
10/3
multiply the numerator by 4
(10/3) * 4 = 40/3
40/3 = 13 1/3
Answer:
the top and bottom combined are 240 and one side is 1200, another side is 500 and another is 1250, so the surface area is 3190 cm
Step-by-step explanation:

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 *
.
