Answer:
See below.
Step-by-step explanation:
x^2 + 2 = 3^2/3 + 3^-2/3
x^2 = 3^2/3 + 3^-2/3 - 2
x = √(3^2/3 + 3^-2/3 - 2)
x = 0.748888296
Substitute for x in 3x^3 + 9x - 8:
3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.
So it is proved.
Step-by-step explanation:
Pear cost=x
Orange cost=x-y
4 pears= 4x
6 oranges=6x-6y or x-y x6
Use ratio.
Pears: x cents
4 Pears: 6x cents
You x4 on each side. Same with oranges.
Orange: x-y
6 oranges: x-y x6
You x6 on each side.
Answer: c. sampling error
Step-by-step explanation:
- A population parameter is a number that is evaluated to describe the whole population . For example : Population mean , Population standard deviation etc.
- A sample statistic gives the estimate value of the population parameter. For example : Sample mean , sample proportion.
Since, the sample is a subset of population , so there are chances for unavoidable variation in sample mean from the population mean that varies from sample to sample .
This variation is known as sampling error.
∴ The difference between the value of the sample statistic and the value of the corresponding population parameter is called the sampling error .
Hence,the correct answer is c. sampling error .
Four types of data (nominal, ordinal, interval, and ratio) that represent values or observations that can be sorted into a category
1/25 because the only number higher than 24 is 25 and you are choosing a number between 1 and 25
