A manufacturing process is designed to produce bolts with a 0.75-inch diameter. Once each day, a random sample of 36 bolts is selected and the bolt diameters recorded. If the resulting sample mean is less than 0.730 inches or greater than 0.770 inches, the process is shut down for adjustment. The standard deviation for diameter is 0.04 inches. What is the probability that the manufacturing line will be shut down unnecessarily? (Hint: Find the probability of observing an x in the shutdown range when the true process mean really is 0.75 inches. Round your answer to four decimal places.)

Answer:the center of the sphere is (1/k, 1/k, 1/k) (or (r/k, r/k, r/k) if r is taken as 1), and the radius is sqrt((1 - ka1)^2 + (1 - ka2)^2 + (1 - ka3)^2) / k.
Step-by-step explanation:
The given vector equation, s(r - kx, y, z) = s(r - ka1, a2, a3) = s(r - kb1, b2, b3) - 0, represents a sphere in three-dimensional space. To find its center and radius, we need to analyze the equation.
Let's compare the given vector equation to the standard equation of a sphere:
(x - h)^2 + (y - k)^2 + (z - l)^2 = r^2.
From the given equation, we can identify the following:
1. Center: The center of the sphere can be found by equating the expressions inside the parentheses to zero.
Setting r - kx = 0, we find that x = r/k.
Setting r - ky = 0, we find that y = r/k.
Setting r - kz = 0, we find that z = r/k.
Therefore, the center of the sphere is (r/k, r/k, r/k), or simply (1/k, 1/k, 1/k) if r is taken as 1.
2. Radius: The radius of the sphere can be found by calculating the distance between the center and any point on the sphere.
Considering the points (r - ka1, a2, a3) and (r - kb1, b2, b3), we can calculate the distance between the center (1/k, 1/k, 1/k) and any of these points.
Using the distance formula, the distance between two points (x1, y1, z1) and (x2, y2, z2) is given by:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2).
Therefore, the radius of the sphere is d = sqrt((1/k - ka1)^2 + (1/k - a2)^2 + (1/k - a3)^2), which simplifies to sqrt((1 - ka1)^2 + (1 - ka2)^2 + (1 - ka3)^2) / k.

Question:
The area of the kite is 48 cm². What are the lengths of the diagonals PR and QS?
________
Solution:
You can split the kite into two isosceles triangles: PSR and PQR.
Assume that both diagonals intersect each other at the point O.
• Area of the triangle PSR:
m(PR) · m(OS)
A₁ = ————————
2
(x + x) · x
A₁ = ——————
2
2x · x
A₁ = ————
2
A₁ = x² (i)
• Area of the triangle PQR:
m(PR) · m(PQ)
A₂ = ————————
2
(x + x) · 2x
A₂ = ——————
2
2x · 2x
A₂ = ————
2
4x²
A₂ = ———
2
A₂ = 2x² (ii)
So the total area of the kite is
A = A₁ + A₂ = 48
Then,
x² + 2x² = 48
3x² = 48
48
x² = ———
3
x² = 16
x = √16
x = 4 cm
• Length of the diagonal PR:
m(PR) = x + x
m(PR) = 2x
m(PR) = 2 · 4
m(PR) = 8 cm
• Length of the diagonal SQ:
m(SQ) = x + 2x
m(SQ) = 3x
m(SQ) = 3 · 4
m(SQ) = 12 cm
I hope this helps. =)
