Answer:

36, 16, 81, and 64.

Step-by-step explanation:

These numbers are perfect squares in that when you find the square root of that number it is a whole number. For example $\sqrt{36}$ = 6 because 6 × 6 =36.

72 is not a perfect square because $\sqrt{72}$ = 8.48528137424, which isn't a whole number.

Answer:

In a 3D space(specifically a plane), there are lines that never intersect but aren't called parallel. So you should change it to, "Parallel lines are two lines wherein each point is equidistant from the opposing line and they never meet"

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

Help me please :''c

wlad13 [49]

Answer:

9) QR = 4.0

10) AC = 4.1

Step-by-step explanation:

Tan = Opps. / Adj.

Tan(60) = 7 / QR

QR = 7 / Tan(60)

QR = 7 / 1.732

QR = 4.0415

QR = 4.0

10)

Tan (27) = AC / 8

AC = Tan(27) * 8

AC = 0.5095 * 8

AC = 4.076

AC = 4.1
