A
both the x and y values are increasing at a steady rate (x by 3 and y by 5)
because it’s y/x, you would put the increase in the y value over the increase in the x value
hope that helps :)
Answer:30%
Step-by-step explanation:
Answer:
y=-3x+31
Step-by-step explanation:
y-y1=m(x-x1)
y-4=-3(x-9)
y-4=-3x+27
y=-3x+27+4
y=-3x+31

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 .
