Answer:
B. 34%.
Step-by-step explanation:
94 - 78 = 16 which is 2 times the standard deviation from the mean.
For a normal distribution this is 34% of the total students.
Your answer is:
60= 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
90= 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
96= 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
The second-highest number of factors are 48 and 80, containing 10 factors each.
The correct option is right-bracket squared 3 squared =x+5
The equation is \log _{3}(x+5)=2
Option a: \log _{3}(x+5)=3^{2}
This is not possible because using logarithmic rule, if \log _{a} b=c then b=a^{c}
Hence, option a is not equivalent to \log _{3}(x+5)=2
Option b: \log _{3}(x+5)=2^{3}
Hence, option b is not equivalent to \log _{3}(x+5)=2
Option c: x+5=3^{2}
This is possible because using logarithmic rule, if \log _{a} b=c then b=a^{c}
Hence, option c is equivalent to \log _{3}(x+5)=2
Option b: x+5=2^{3}
Thus, the correct option is c: x+5=3^{2}
Hence, the equation x+5=3^{2} is equivalent to \log _{3}(x+5)=2
Answer: it is C
A. t(x) = 450 - 0.06x
The layer which is originally 450 m thick is decreasing by 0.06 m.
450 - 0.06
... per day. x represents days.
0.06x
So,
450 - 0.06x
