Answer:
153.94
Step-by-step explanation:
The formula for the area of a circle is
A = ![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20%20r%5E%7B2%7D)
If the diameter is 14 in the to get the radius all you have to do is divide it by 2 to get 7
R is radius
R = 7
plug in 7 for R in the equation
*![7^{2}](https://tex.z-dn.net/?f=7%5E%7B2%7D)
and you will get 153.94
Answer:
Hello! answer: x = 50
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees! so...
50 × 3 = 150 150 - 20 = 130
130 + 50 = 190 therefore x = 50 hope that helps!
The two-way table is attached.
We know that 63 people took the survey, and 22 of them were left-handed. This means that 63-22=41 of them are right handed.
Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.
Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.
Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.
Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.
Z= 3(-4-a)/4(4n+3p)
Multiply z by the denominator of the function to start to get things all on one side.
Z(4(4n+3p)=3(-4-a)
Divide by 3 to remove the parentheses from the right side.
4Z(4n+3p)/3=-4-a
Add four to both sides to remove it from the right.
4Z(4n+3p)+4/3=-a
Multiply by -1 to get a all by itself.
-4Z(4n+3p)+4/3=a
