Answer:

$\bold{8\pi}$ or $\bold{25.12}$

Step-by-step explanation:

We know that as shown by the diagram, the radius is 4. So in this case, we want to find the circumference of the entire circle, then just multiply by $\frac{3}{4}$ , because the radii from the intact section are perpendicular.

The circumference of a circle is just $\pi \times d$ where $d$ is the diameter of the circle. The diameter is just the radius $\times 2$ which gives us

$d = 4 \times 2 = 8$

Thus lending us $8\pi$ or $25.12$ if we substitute $\pi$ with 3.14.

Q = {1.7, 1.1, 1.4, 2.1, 2.3, s}. What is the absolute difference between the greatest and least possible values of the median o

Daniel [21]

Answer:

Absolute difference between the medians = 0.35

Step-by-step explanation:

After arranging Q in ascending order excluding s, we get

Q = {1.1, 1.4, 1.7, 2.1, 2.3}

Here, the median is 1.7 ( The middlemost value is the required median.)

Now, if s < 1.7,

Q= {1.1, s, 1.4, 1.7, 2.1, 2.3}

Now for the least value, median = 1.55

If s > 1.7,

Q = {1.1, 1.4, 1.7, 2.1, s, 2.3}

Now for the greatest value, median = 1.9

Absolute difference between the medians = |1.9 -1.55|

= 0.35

Adding or subtracting fractions with different denominators

Bas_tet [7]

Step-by-step explanation: You can't continue on with the problem until the denominators are the same. So you need to find the LCD (Least Common Denominator). For example...

$\frac{1}{2} +\frac{1}{3}$ The LCD is six

$\frac{1*3}{2*3}=\frac{3}{6} =\frac{1}{3}$

$\frac{1}{2}+ \frac{1}{3}= \frac{3}{6} +\frac{2}{6}$

$\frac{3+2}{6}= \frac{5}{6}$

Hope this helps, have a BLESSED and wonderful day! :-)
