Answer and Step-by-step explanation:

Area of triangle:

A = $\frac{bh}{2}$ (Base times height, all divided by 2)

Area of Rectangle/Square

A = bh (base times height)

Triangle:

$\frac{7*24}{2} = \frac{168}{2} = 84$

Rectangle:

A = 12.5 * 13 = 162.5

162.5 + 84 = 246.5

Which equation demonstrates the additive identity property?

Vika [28.1K]

we know that

Additive identity property:

If we add a real number to zero or add zero to a real number, then we get the same real number back.

The number zero is known as the identity element, or the additive identity.

For example: a+0 =a

we can see that adding gives same result

so, 0 is the additive identity here

Hence , option-B........Answer

Refer to the data set of body temperatures in degrees Fahrenheit given in the accompanying table and use software or a calculato

Mariulka [41]

The mean of the dataset is the average, while the median is the middle element.

The mean and the median of the given dataset is 98.2
The results support the common belief that the mean body temperature is 98.6F

The mean of the dataset is calculated using:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x = \frac{99.2+ 99.2 +98.2+............+97.7}{48}$

$\bar x = \frac{4715}{48}$

$\bar x = 98.2$

The median position is:

$Median = \frac{1}{2}(n + 1)$

$Median = \frac{1}{2}(48 + 1)$

$Median = \frac{1}{2}(49)$

$Median = 24.5$

This means that the median is the average of the 24th and 25th element

Using the sorted dataset, we have:

$Median = \frac{1}{2}(98.2 + 98.2)$

$Median = 98.2$

Because the calculated mean and the common belief (98.6) are close, then we can conclude that the results support the common belief that the mean body temperature is 98.6F
