In the following figure, the square ABCD is inscribed in the circle centered at point P. What is the area of the circle?
Ainat [17]

Answer:

A_{Circle} \approx 39.24\: units^2

Step-by-step explanation:

Square ABCD is inscribed in a circle with center P such that BC = 5 units.

BD will be diagonal of the square as well as diameter of the circle.

BD = BC\times\sqrt 2

\implies BD = 5\sqrt 2

-> Diameter of the circle (d) = 5\sqrt 2

-> Radius of the circle (r) = 2.5\sqrt 2=3.535\: units

A_{Circle} =\pi(r)^2

\implies A_{Circle} =3.14(3.535)^2

\implies A_{Circle} =3.14(3.535)^2

\implies A_{Circle} =39.2381465

\implies A_{Circle} \approx 39.24\: units^2

The dot plot shows how many cats are owned by each person in a neighborhood:
REY [17]

If we plot the data on the graph, we can see that the data is skewed to the right (positive skew) and there is an outlier. In skewed data and presence of outlier, the median is most commonly used measure of central tendency. This is because a positive skew would result in a positive bias to the mean. Meaning that it would be a lot larger than the median and not really representing the actual central tendency. The median however is less affected by the skew and outliers.

Answer: Median, because the data are skewed and there is an outlier

dybincka [34]
The words literally tell you what to do.
<em>b</em> = the number of bags.

You need to "divide the cookies evenly"

We have "48 cookies".

Now we need to put that together.

48/<em>b</em> is your answer.

X - 7 = 13 - x help asap plz
bekas [8.4K]

Answer:

x = 10

Step-by-step explanation:

x - 7 = 13 - x

Step 1 : Collect like terms and simplify

x + x = 13 + 7 \\ 2x = 20

Step 2 : Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{20}{2}

Step 3 : Simplify by cross cancellation of common term : 2

x = 10
