A school district's superintendent wants to administer a test of life skills to a sample of students. The superintendent has amp
tangare [24]

Answer:

-Convenience Sampling

Step-by-step explanation:

Convenience Sampling is a sampling method that is employed simply because the samples are easy to reach or access. It is a non-probability system of sampling and not a very strong method of sampling. For a serious research such as the one being conducted by the Superintendent, who has ample time to perform the research, this is not a very good sampling method. A Convenience style of research would mean that he can just walk into a cafeteria with students and administer the test to them.

Since he has detailed information of the students, he should choose any of the other mentioned sampling techniques in the options provided to randomly select the subjects. <em>This would help to</em> prevent bias, and enable him to make generalizations with the result of the research.

Find the absolute value of 2 and 2 3rd and negative 9 over 4
gayaneshka [121]

we are given

absolute value of 2 and 2 3rd and negative 9 over 4

Firstly , we need write it in terms of expression

2 and 2 3rd is

2+\frac{2}{3}

so, we get as

|2+\frac{2}{3} -\frac{9}{4} |

now, we can simplify it

Firstly , we will find common denominator

|\frac{2*12}{1*12} +\frac{2*4}{3*4} -\frac{9*3}{4*3} |

|\frac{24}{12} +\frac{8}{12} -\frac{27}{12} |

we can see that

all denominators are same

so, we can combine numerators

=|\frac{24+8-27}{12}  |

=|\frac{5}{12}  |

=\frac{5}{12}..............Answer

Martha estimated the quotient of -71.81 and -8.02 using
steposvetlana [31]

Option 2

Martha estimated the quotient. Martha error was she should have rounded -8.02 to -8.

<u>SOLUTION: </u>

Given that, Martha estimated the quotient of -71.81 and -8.02 using rounding to the nearest whole number.

And she committed an mistake. We have to find the error made by Martha while calculating quotient.

She treated -71.81 to be 72 and -8.02 to be 9. As both the number are negative there will be no problem when we get quotient.

When treated as above she got quotient as 8.

But in general, the quotient is not 8.

If we see options, we derive an conclusion.

<u>Option (1) </u>

she should have rounded 71.81 to 70, no this is not correct as 72 is nearest whole number.

<u>Option (2)</u>

she should have rounded 8.02 to 8, yes this is correct conclusion.

<u>Option (3)</u>

she should have divided 8 by 72, no this is not correct, we should divided 72 by 8.

<u>Option (4) </u>

she didn’t make an error, this is wrong as in 2nd option we caught an error.

Hence, second option is correct.
