Answer:
Radius length: √5
Standard Form (Equation): (x + 4)^2 + y^2 = 5
Step-by-step explanation:
First we will determine the radius;
Center: (-4, 0)
Point on Circumference: (-2, 1)
d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2
= √4 + 1 = √5
Therefore the radius is of length √5
Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.

Answer:
The area of the shaded region is 0.2898.
Step-by-step explanation:
Let <em>X</em> represent the IQ scores of adults.
It is provided that
.
Compute the probability of an adult having an IQ between 106 and 124 as follows:

*Use a <em>z</em>-table.
Thus, the area of the shaded region is 0.2898.

Turn it into an improper fraction
Multiply 7 and 4 and add 3 which is over 4 which is

Multiply by 4 | for each bracelet being made


124÷4=31
Answer:You need 31 inches to make all the braclets
Perimeter=120
ED=x (length)
FE=4x (breadth)
Perimeter of rectangle= 2(l+b)
Given,
2(x+4x)=120
2x+8x=120
10x=120
x=120÷10
x=12
Therefore, value of x is 12
