Answer: A
Step-by-step explanation:
Answer:14
Step-by-step explanation:
x-1/2=x/4+3 multiply left and right side of equation with 4 you get:
4x-2=x+12
------------------
4x-2=x+12
4x-3x=12+2
x=14
The location of K(1,-3) after dilated by a scale factor of 1 is K’(1,-3) also
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 .
Formula: Area = pi x radius(squared)
The radius 5.5mm is half of the diameter 11mm
Answer: 3.14159 x 5.5mm^2 = 95.033mm^2
