Answer:

Normally Distributed.

Explanation:

After plugging all those numbers into a calculator you can see that the graph isn't left skewed, making both "left skewed" and "all of the above" <em>not an answer.</em> "correlated with a second set of data" is also <em>wrong</em> since there was no second set of data given. That leaves you between "uniformly distributed" and "normally distributed" This graph doesn't show a uniformly distributed graph, which leaves you with the final answer, normally distributed.

Suppose you know the area of a circle and the measure of the central angle of a sector. Describe the process of finding the area
coldgirl [10]

Answer:

360

Area

Step-by-step explanation:

The formula of the area of a sector in a circle is:

Area of sector = \frac{x}{360} × πr², where

  • x is the central angle of the sector
  • πr² is the area of the sector

Example:

The measure of a central angle is 60°, and the area of the circle is 12π unit², then the area of the sector of the central angle is:

Area of the sector = \frac{60}{360} × 12π = 2π

To find the area of the sector

Divide the measure of the central angle by 360

Multiply the result by Area of the circle

Find the equation for the line that passes through the point (3,-2), and that is perpendicular to the line with the equation x =
kompoz [17]

Step-by-step explanation:

x = 2 is, as you can see, parallel to the y-axis.

perpendicular to this (= crosses the original line in an angle of 90 degrees) is then a line parallel to the x-axis.

that means y is constant. all points on that line will have the same y value.

and we know one point already : (3, -2)

so all points of the perpendicular line will have y = -2

and that is the equation of the perpendicular line :

y = -2

the variable Z1 and Z2 are defined as z1 equals 6i+3i and z2 equals 10 + 8i which expression is equivalent to Z1Z2
Alexxx [7]
If you multiply the two numbers, you will have 36 + 78i.
*I assumed you had a typo in the first expression, it is generally written as 6 + 3i. If you meant, 6i + 3i, it should have been just 9i.

To find this product, we use the foil method.

(6 + 3i)(10 + 8i)
60 + 48i + 30i + 24i^2
60 + 78i + 24(-1)
34 + 78i
