Answer:

Step-by-step explanation:

Find the area of the circle with r = 36/2 Area1 = π r²

divide Area1 by two since the upper part of the figure is a semi-circle

then finally add and area of the rectangle Area2 = (18)(36)

Total area = Area 1 + Area 2

Answer:

1156.7 cm^2

Step-by-step explanation:

for finding area of semi circle

diameter=36 cm

radius=diameter/2

=36/2

=18 cm

area of semi circle=πr^2/2

=3.14*(18)^2/2

=3.14*324/2

=1017.36/2

=508.68 cm^2

area of rectangle=length*breadth

=18 cm *36 cm

=648 cm^2

area of the figure=area of semi circle + area of rectangle

=508.68 + 648

=1156.68

=1156.7 cm^2

How do u do stat edit

Svetlanka [38]

Answer:

The stat command has two options that allows you to customize the output according to your needs: -c, (--format="format") and --printf="format". The difference between these two options is that when two or more files are used as operants --format automatically adds a newline after each operand’s output.

Andrew and Michael are 15 miles apart. If they walk towards each other, they meet in 3

andrew11 [14]

Answer: Andrew - 1.875 Michael- 3.125

Step-by-step explanation:

If Andrew overtakes in 8 hours, we can divide 15 miles by 8 to see how many miles per hour he goes.

15/8 = 1.875

Then we can multiply 1.875 by 3 to see how much he traveled while walking towards Michael.

1.875*3=5.265- the distance he traveled

Now subtract that by 15 to see how many miles Michael walked.

15-5.625=9.375

That means Michael walked 9.375 miles.

Divide 9.375 by 3 to see how many miles he walked per hour

9.375/ 3 = 3.125

Dual-energy X-ray absorptiometry (DXA) is a technique for measuring bone health. One of the most common measures is total body b

kramer

Answer:

(a)

$\bar x = 0.0075$

$s = 0.0049$

(b)

B. The sample is too small to make judgments about skewness or symmetry.

Step-by-step explanation:

Given:

$n = 8$

$\begin{array}{ccccccccc}{} & {S} & {u} & {b} &{j} & {e} & {c} & {t} & {s} &{Operator} & {1} & {2} & {3} & {4} & {5} & {6} & {7} & {8} & {1} & 1.326 & 1.337 & 1.079 & 1.229 & 0.936 & 1.009 & 1.179 & 1.289 & 2 & 1.323 & 1.322 & 1.073 & 1.233 & 0.934 & 1.019 & 1.184 & 1.304 \ \end{array}$

Solving (a):

First, calculate the difference between the recorded TBBMC for both operators:

The last row which represents the difference between 1 and 2 is calculated using absolute values. So, no negative entry is recorded.

The mean is then calculated as:

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

$\bar x = \frac{0.003 + 0.015 + 0.006 + 0.004 + 0.002 + 0.010 + 0.005 + 0.015}{8}$

$\bar x = \frac{0.06}{8}$

$\bar x = 0.0075$

Next, calculate the standard deviation (s).

This is calculated using:

$s = \sqrt{\frac{\sum (x - \bar x)^2}{n}}$

So, we have

$s = \sqrt\frac{(0.003 - 0.0075)^2 + (0.015 - 0.0075)^2+ (0.006- 0.0075)^2+ ....... + (0.005- 0.0075)^2+ (0.015- 0.0075)^2 }{8}$ $s = \sqrt\frac{0.00019}{8}$
