Explain the difference between perimeter and area.why do they measure?what type of units are they measured in?

just olya [345]

Perimeter is the distance around an object / shape. Area is the amount of space within a 2 dimensional surface. For example the perimeter of a square would be the lengths of each side added together while the area would be how much space inside of it that it occupies. Area is measured in units squared, while perimeter is left in just units. In other words if the unit ( measurements ) are conducted in cm, then the area would be put in cm^2. The perimeter would just remain in cm.

I need help someone please

statuscvo [17]

Answer: $\frac{6}{2}$

Step-by-step explanation:

1. Use this $\frac{f(b)-f(a)}{b-a}$ to find the average rate of change

2. Average rate of change = $\frac{f(8)-f(6)}{8-6}$

3. $f(8) = - 4$ and $f(6) = -10$ (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like $\frac{-4-(-10)}{8-6}$

6. Solve $\frac{6}{2}$

SAT scores have a mean of 1026 and a standard deviation of 209. ACT scores have a mean of 20.8 and a standard deviation of 4.8.

Y_Kistochka [10]

Answer:

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

Step-by-step explanation:

Mean SAT scores = 1026

Standard Deviation = 209

Mean ACT score = 20.8

Standard Deviation = 4.8

We are given SAT and ACT scores of a student and we have to compare them. We cannot compare them directly so we have to Normalize them i.e. convert them into such a form that we can compare the numbers in a meaningful manner. The best way out is to convert both the values into their equivalent z-scores and then do the comparison. Comparison of equivalent z-scores will tell us which score is higher and which is lower.

The formula to calculate the z-score is:

$z=\frac{x-\mu}{\sigma}$

Here, μ is the mean and σ is the standard deviation. x is the value we want to convert to z score.

z-score for junior scoring 860 in SAT exam will be:

$z=\frac{860-1026}{209}=-7.59$

z-score for junior scoring 16 in ACT exam will be:

$z=\frac{16-20.8}{4.8}=-1$

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

Which letter is the correct answer and why

Julli [10]

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>C</u></em></h2>

Step-by-step explanation:

<em><u>Here</u></em><em><u>,</u></em>

<em>[</em><em>Taking</em><em> </em><em>'</em><em>A'</em><em> </em><em>=</em><em> </em><em>'</em><em>a'</em><em>]</em>

$a \: = \: 4\pi {r}^{2}$

<em><u>Then</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>'</u></em><em><u>r</u></em><em><u>'</u></em><em><u>,</u></em>

$= > 4\pi {r}^{2} = a$

$= > {r}^{2} = \frac{a}{4\pi}$

$= > r = \sqrt{\frac{a}{4\pi} }$

$= > r = \frac{1}{2}\sqrt{ \frac{a}{\pi} }$

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Option</u></em><em><u> </u></em><em><u>C</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>correct</u></em><em><u> </u></em><em><u>.</u></em>

DECISION SCIENCE Assume more restrictions. The books pass through two departments: Graphics and Printing, 1. before they can be

STALIN [3.7K]

Answer: The value of x and y are 2 and 15 respectively.

Step-by-step explanation:

Since we have given that

Number of hours available in graphics = 21 hours

Number of hours in printing = 19 hours

Number of hours required by x in graphics = 3

Number of hours required by x in printing = 2

Number of hours required by y in graphics = 1

Number of hours required by y in printing = 1

According to question, we get that

$3x+y=21\\\\2x+y=19$

Using the graphing method, we get that

x = 2 and y = 15

Hence, the value of x and y are 2 and 15 respectively.
