A stamp has the Length of 1/2 cm and a width of 1 1/2 is the area of the stamps

avanturin [10]

Answer:

$Area = \frac{3}{4} cm^2$

Step-by-step explanation:

Given

$Length =\frac{1}{2}\ cm$

$Width = 1\frac{1}{2}\ cm$

Required

Determine the Area

Area is calculated as follows

$Area = Length * Width$

Substitute values for Length and Width

$Area = \frac{1}{2} * 1\frac{1}{2}$

Convert mixed fraction

$Area = \frac{1}{2} * \frac{3}{2}$

$Area = \frac{3}{4}$

Hence, the area is

$Area = \frac{3}{4} cm^2$

inessss [21]

Answer:

Step-by-step explanation:

To estimate population proportion from a sample, we must ensure that the sample data is random. Though a simple random sample of college students from a particular college was used as the sample data. However, selection of the college should have been randomized as well, a stratified random sample would have been a better sampling method whereby certain colleges are selected based on region or other criteria and then a random sample of it's statistics students selected. The sample proportion Obtian from a sample of this nature will be more representative of the population proportion of all college statistic student.

zhuklara [117]

As per the problem,

Rhonda bought a new laptop for $800.

The laptop depreciates, or loses, 20% of its value each year.

The value of the laptop at a later time can be found using the formula

$A=P(1-r)^t.....(1)$

Here we have

P=$800

r=20%=0.20

t=2 years

Substitute the values in equation (1) we get

$A=800(1-0.2)^2\\ \\ \Rightarrow A=800(0.8)^2\\ \\ \Rightarrow A=800*0.64\\ \\ \Rightarrow A=512\\$

The laptop be worth in two years will be $512.
