Answer: 6/5
Step-by-step explanation:
When finding the reciprocal, we essentially just "flip" or take the inverse of the number we are given. For example, the reciprocal of 1/2 would be 2/1 or 2. The given number multiplied by the reciprocal should always equal 1. If it does, then we know we are correct.
In this case, we are finding the reciprocal of 5/6, so we "flip" the numerator and the denominator to get 6/5.
To check our work, we need to multiply our original number and its reciprocal.
5/6 x 6/5 = 30/30 = 1
Now, we know we are correct, that the reciprocal of 5/6 is 6/5.
Either it is C or D or E.

Answer:
The answer to your question is 24x³ - 46x²- 28x + 63
Step-by-step explanation:
Data
(6x² - x - 9)(4x - 7)
Process
1.- Multiply 4x by the three terms of the first polynomial
(6x² - x - 9)(4x) = 24x³ - 4x² - 36x
2.- Multiply -7 by the three terms of the first polynomial
(6x² - x - 9)(-7) = -42x² + 7x + 63
3.- Add both result
24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63
Answer:
Observational study
Step-by-step explanation:
There are 3 types of statistical study:
1) Experimental: Under this, any experiment is done on a certain group of population.
2) Observational: Under this study, the events are observed regularly and the record is made.
3) Survey : Under this study, a survey is conducted with a a group of population and the record is made.
According to question, A meteorologist keeps hourly temperature records over the course of several years in order to look for long-term variations, this is an example of <u>observational study</u>.
