total surface area Stot = 688 mm2
lateral surface area Slat = 324 mm2
top surface area Stop = 182 mm2
bottom surface area Sbot = 182 mm2
Answer:
a. 99.7%
b. 68%
Step-by-step explanation:
The empirical rule for approximately symmetrical and bell-shaped distributions states that:
68% of the data are among the values (means - sd) and (means + sd)
95% of the data are among the values (means - 2*sd) and (means + 2*sd)
99.7% of the data are among the values (means - 3*sd) and (means + 3*sd). So that,
68% of the data are among the values (180 - 8) = 172 and (180 + 8) = 188
95% of the data are among the values (180 - 16) = 164 and (180 + 16) = 196
99.7% of the data are among the values (180 - 24) = 156 and (180 + 24) = 204
Lets x = KB
2/5 = 3/(x+3)
2(x+3) = 3(5)
2x+6 = 15
2x = 9
x = 4.5
answer
KB = 4.5 cm
8th term = 256/729
Step-by-step explanation:
Ratio = a2/a1
2/3 = a2/6 a 2=2/3*6 =12/3 =4 a2=4
1) 6* 2/3=4
2) 4*2/3=8/3
3) 8/3*2/3 = 16/9.......
