Answer:
The Babylonians employed a number system based around values of 60, and they developed a specific sign—two small wedges—to differentiate between magnitudes in the same way that modern decimal-based systems use zeros to distinguish between tenths, hundreds and thousandths.
Answer:
No correct answer
Step-by-step explanation:
volume of a cylinder= pi*r2*height
making height the subject of formula
height = volume/pi*r2
height= 8.478/pi*15*15 = 0.012in
Distribute the .25 to get .25x + 1 - 3 = 28
Then simplify to get .25x - 2 = 28
Move the two to the right to get .25x = 30
Then divide to leave x: 30 / .25 = 120
X = 120
Answer:
Both are rational.
Step-by-step explanation:
a. 4/7 + (-1/3) = 5/21 which is rational
b. √4 x 2/5 = 4/5 which is rational
Answer:
<u>Standard deviation for owner-occupied units</u>
2.9797
<u>Standard deviation for renter-occupied units</u>
3.1594
Step-by-step explanation:
Let us find first the mean. This is the distribution expected value or expectancy.
<u>Mean for owner-occupied units</u>
0.003 + 2*0.002 + 3*0.023 + 4*0.102 + 5*0.209 + 6*0.223 + 7*0.201 + 8*0.149 + 9*0.053 + 10*0.035 = 6.293
To compute the variance for owner-occupied units, we add these values


then divide by 10 and take the square root to get the standard deviation 2.9797
<u>Mean for renter-occupied units</u>
0.008 + 2*0.027 + 3*0.287 + 4*0.371 + 5*0.155 + 6*0.090 + 7*0.043 + 8*0.013 + 9*0.003 + 10*0.003 = 4.184
To compute the variance for renter-occupied units, we add these values


then divide by 10 and take the square root to get the standard deviation 4.184
