Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
64 = 4x + 8
4x = 56
x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm
Answer:
width = 14 cm
length = 50 cm

8-Figures represents eight digits and a 8-figure salary will fall between $10,000,000 – $99,999,999. People who are earning this amount of income are typically multi-millionaires and would be considered quite wealthy.
Using the t-distribution, it is found that the value of the test statistic is t = -87.3.
At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:
At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:
.
We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
The values of the <em>parameters </em>are: 
.
Hence, the value of the <em>test statistic</em> is:
