The length of DE 21.26029163 units
Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
Answer:
radius of the hemisphere = 9 cm approx
Step-by-step explanation:
Volume of hemisphere = ![\frac{2}{3} \pi r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D)
1527.4 = ![\frac{2}{3} * \frac{22}{7} * r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20%2A%20%5Cfrac%7B22%7D%7B7%7D%20%2A%20r%5E%7B3%7D)
= ![r^{3}](https://tex.z-dn.net/?f=r%5E%7B3%7D)
= ![r^{3}](https://tex.z-dn.net/?f=r%5E%7B3%7D)
= 729
r = ![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
r = 9 cm approx.
Answer:
-6
Step-by-step explanation:
-6/b-50=-49
step1;collect like terms
-6/b=-49+50
-6/b=1
step2;cross multiply
-6/b=1
-6=1b(1b can also be regarded as b)
b=-6
