Ok, you have your equation 15=x/6-1.
First, add 1 to both sides, get 16=x/6.
Then, multiply both sides by 6.
Get your answer of x=96
Hope this helps

What is the common difference of the arithmetic sequence 5, 8, 11, 14?

AnnZ [28]

Answer:

The common difference is 3

Step-by-step explanation:

we know that

In an <u>Arithmetic Sequence</u> the difference between one term and the next is a constant called the common difference

we have

$5,8,11,14$

$a1=5$

$a2=8$

$a3=11$

$a4=14$

$a2-a1=8-5=3$

$a3-a2=11-8=3$

$a4-a3=14-11=3$

therefore

The common difference is 3

The difference between the value of the sample statistic and the value of the corresponding population parameter is called the _

mel-nik [20]

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 .
