Pay attention here because I'm adding an extra letter to our circle to help keep track of the values in our formula.  OUTSIDE of the intercepted arc I'm adding the point E.  So the major arc is arc BEG and the minor arc is arc BG.  The formula then for us is ∠BFG= \frac{1}{2}(arcBEG-arcBG).  We just don't have values for the arcs yet.  If the measure of the central angle is 4x+238, then the measure of arcBG is also 4x+238.  Around the outside of the circle is 360°.  So we will use it in an expression.  ArcBEG=360-(4x+238).  Fitting that into our formula we have 2x+146= \frac{1}{2}[(360-4x-238)-(4x+238)].  Doing all the simplifying inside there we have 2x+146= \frac{1}{2}(122-4x-4x-238) and 2x+146= \frac{1}{2}(-8x-116).  Multiply both sides by 2 to get rid of the fraction: 4x+292=-8x-116.  Combine like terms to get 12x = -408 and divide to solve for x.  x = -34.  Fourth choice down from the top.

Step-by-step explanation:

Given the following refrigerator characteristics :

brand name and model - - > CATEGORICAL

whether it has a top freezer, bottom freezer, or side-by-side LAYOUT - - > CATEGORICAL

the estimated energy consumption per year (kilowatts); - - - > QUANTITATIVE

whether or not it is Energy Star COMPLIANT - - > CAREGORICAL

the width, depth, and height in INCHES - - - > QUANTITATIVE

both the freezer and refrigerator net capacity, in cubic FEET - - - > QUANTITATIVE

To start with ; Categorical and quantitative variables differ most notably in the fact that, quantitative variables deals with numbers, measurements or calculated mathematical values of certain attribute in a measured species or sample. Categorical variable on the other hand mostly deals with making distinctions in properties of a sample by grouping the varibale into the different available categories based on their attributes.

A circle has a radius of 5 centimeters. What is the area?
schepotkina [342]

Answer:

25\pi

Step-by-step explanation:

The formula for the area of a circle is A=\pi r^{2}, r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however 25\pi is the exact answer.
