Answer:

The appropriate hypotheses for performing a significance test is:

$H_0: \mu = 51$

$H_1: \mu > 51$

Step-by-step explanation:

Last year, the mean score on the state’s math test was 51. The administrators have trained the teachers in a new method of teaching math hoping to raise the scores on this standardized test this year.

At the null hypothesis, we test if the mean score this year is the same as last year, that is:

$H_0: \mu = 51$

At the alternate hypothesis, we test if the mean score improved this year from last, that is:

$H_1: \mu > 51$

The appropriate hypotheses for performing a significance test is:

$H_0: \mu = 51$

$H_1: \mu > 51$

The width of a rectangle is equal to m cm, but it’s length is five times greater than the width. Find the area of the rectangle.

Irina18 [472]

Area of rectangle is $5m^{2}\ cm^{2}$

Step-by-step explanation:

Given,

Width of rectangle = m cm

As length is 5 times more than width;

Length of rectangle = 5m cm

Area of rectangle = Length x Width

$Area\ of\ rectangle = 5m*m\\Area\ of\ rectangle = 5m^{2} \\As\ length\ and\ width\ both\ are\ in\ cm\,\ therefore\\Area\ of\ rectangle = 5m^{2}\ cm^{2}$
