3x -2(5x + 4) - 1 = 0
3x - 10x -9 = 0
3x - 10x = 9
-7x = 9 x= 9/-7 x=-9/7
y = 5(-9/7) + 4
y= -17/7
The answer is A
Answer:
34% of scores should fall between your score and the mean.
Step-by-step explanation:
Let <em>X</em> denote the score.
It is provided that X follows a normal distribution with mean 110 and standard deviation 15.
A students score, <em>x</em> = 95.
Compute the probability of scores that should fall between the student's score and the mean as follows:


Thus, 34% of scores should fall between your score and the mean.
the answer is C im fairly certain
Answer:
5000 particles of size 10 nanometer should be stacked
Step-by-step explanation:
Average diameter of the of the human hair = 50 micron = 50 × 10⁻⁶ m
Now,
let the number of 10 nanometer i.e 10 × 10⁻⁹ m particle be 'n'
thus,
n × 10 × 10⁻⁹ m = 50 × 10⁻⁶ m
Therefore to find the number of 10 nanometer i.e 10 × 10⁻⁹ m particle,
n = 
or
n = 5000
Hence,
5000 particles of size 10 nanometer should be stacked
