Ok, so first convert both the numbers to improper fractions. (Multiply the denominator of the fraction by the whole number and add the numerator of the fraction)
Then keep the first number the same, change the division symbol to a multiplication symbol and use the reciprocal of the second number. (flip the numbers so that the denominator becomes the numerator and the numerator becomes the denominator.)
Then simply multiply across.
Answer:
x . 2 = y
Step-by-step explanation:
What's the question..like what are the instructions
Answer:

Step-by-step explanation:
apply the inverse properties of logarithmic and exponential functions to simplify

Inverse property of log says that

we apply this property in our problem. ln has same base 'e' . so ln and e gets cancelled




So to find the mean you add them all together and divide by the number of numbers there is so 11+15+19+17+23+20+17+18+21=174 and there are 10 numbers so it would be 174/10 which is 17.4 so you answer is 17.4
