Answer:
Part A: 100
Part B: 625
Step-by-step explanation:
Part A equation: 25 x 4 = 100
Part B equation: 25 x 25 = 625
The volume of the cube with the given side length is 1/125b⁹
<h3>Calculating the volume of a cube</h3>
From the question, we are to determine the volume of the given cube.
The volume of a cube is given by
V = s³
Where V is the volume of the cube
and s is the side length of a side of the cube
From the given information,
s = 1/5b³
Thus,
The volume of the cube will be
V = 1/5b³ × 1/5b³ × 1/5b³
V = 1/5 × 1/5 × 1/5 × b³ × b³ × b³
V = 1/125 × b⁹
V = 1/125b⁹
Hence,
The volume is 1/125b⁹

=1 I calculated the combine value
<span>Note that the mean (78 +90 +456 +676 + 111+ 381+ 21)/7 = 259
The differences (in absolute value - we're going to square later so it doesn't matter) between each piece of data and the mean are
181, 169, 197, 417, 148, 122, 238
Square each of these and add the results together to obtain 367452
Now your question depends on whether you want the sample standard deviation or population standard deviation - which you have not specified. In the first case divide by 6. In the second case divide by 7. We get roughly 61242 or 52493. The square root of each yields 247.47 or 229.11 depending on whether you want the sample sd or pop sd. The 4 choices imply you are looking for the latter, so the answer is A.i think</span>
Equal - you can remember by ‘equil’ in equilateral sounding a lot like equal
