35 49 51 54 65 51 52 47 87 37 46 33 39 44 39 64 94 34 30 48
is the sample given
From the above we can find
Mean =sum of all observations /20
= 
Variance = ![\frac{1}{20} [\Sigma_1^{20} (x_i-49.95)^2 ]\\=269.7475](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D%20%5B%5CSigma_1%5E%7B20%7D%20%28x_i-49.95%29%5E2%20%5D%5C%5C%3D269.7475)
Std deviation= square root of variance
= 16.424
Population estimate for mean = 49.95
Population estimate for std dev =
=3.673
The value that separate 50% top form 50% bottom is the median
Median is the middle value after arranging in ascending order
=average of 47 and 48 = 47.5
Proportion of atleast 60 = 2/20 = 0.1
1. 360-111-90-90=?
2. 180-90-12=?
3. (24+50)²=?²+24²
5. 8.6²=5²+?²
Option A:
Volume of the pyramid = 25 cm³
Solution:
<u>To find the volume of the pyramid:</u>
Base area = length × width
= 5 cm × 5 cm
Base area = 25 cm²
Perpendicular height of the pyramid = 3 cm
Volume of the pyramid = 

= 25 cm³
Volume of the pyramid = 25 cm³
Hence option A is the correct answer.
