Answer:
A 23 of people who prefer plan 1 are from the 35-45 age group and 42% of people from the 46-55 age group prefer plan 2.
Step-by-step explanation:
add everyone who prefers plan 1 = 60
age 36-45 / total of plan 1 = 14/60 = .23 or 23%
add everyone in age group 46-55 = 50
in age group 46-55 and prefers plan 2 = 21 / 50 = 0.42 or 42%
3/4x^2 + 2x - 5 is the correct answer
Answer:
Make sure you are using a perfect circle. This method won't work with ellipses, ovals or anything but a real circle. A circle is defined as all the points on a plane that are an equal distance from a single center point. The lids of jars are good household objects to use for this exercise.You should be able to calculate pi roughly because in order to get exact results of pi, you will need to ...
Measure the circumference of a circle as accurately as you can. The circumference is the length that goes around the entire edge of the circle. Since the circumference is round, it can be difficult to measure (that's why pi is so important). Lay a string over the circle as closely as you can. Mark the string off where it circles back around, and then measure the string length with a ruler.
Measure the diameter of the circle. The diameter runs from one side of the circle to the other through the circle's center point.
Use the formula. The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14.[3] X Research source
Repeat this process with several different circles, and then average the results.
Step-by-step explanation:
Just simply divdie
5/21= .23 or about .24
The measure of the angle EFD will be 68 degrees. The correct answer is option B.
<h3>What is an angle?</h3>
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that:-
The arc angle is 68 degrees and we need to find the angle EFD.
As it is given in the question that the angle suspended by the arc is 68 degrees so the angle EFD will also be equal to 60 degrees.
Therefore the measure of the angle EFD will be 68 degrees. The correct answer is option B.
