Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of arc EH
Remember that the measure of the complete circle is equal to 360 degrees
so
Remember that
----> by central angle
----> by central angle
---> by central angle
substitute the given values
step 2
Which arc is congruent to Arc E H?
we know that
therefore
arc EH is congruent with arc EFG
or
arc EH is congruent with minor arc GE
he equation of any horizontal line is
y = .. a number
The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.
In this case the line passes though the point (−8,9)
which tells us that the y-value we want is 9.
Therefore the equation is y=9
Answer:
Step-by-step explanation:
Mean = 0.53*23.7% + 0.25*12.7% + 0.22*(-0.112)= 15.71%
standard deviation= sqrt(0.53*(23.7%-15.71%)^2 + 0.25*(12.7%-15.71%)^2 + 0.22*(-0.112-12.40%)^2)= 8.40%
Answer:
Length = 8 in. Perimeter = 28 in.
Step-by-step explanation:
The equation for finding area is: A = l*w
Let's put the values we already know into the equation
48 = l * (6)
Divide both sides by 6 to isolate the l
8 in. = l
We know this answer is correct because 8 * 6 = 48
Now that we know that the length is equal to 8, we can solve for the perimeter.
To find the perimeter you have to add the values of all of the sides together.
Since we know that the top of a letter box is in the shape of a rectangle, we know that two of the sides are 6 in. and the other two sides are 8 in.
6 + 6 + 8 + 8 = 28 in.
