Answer:
what we have to find in this question
Slope: M = rise/run = y2 - y1/x2 - x1
Point slope: y-y₁=m(x-x₁)
Slope-intercept: y = mx+b
The surface area of a regular tetrahedron with edge length s is
... A = (√3)s²
For your edge length of 4 inches, the surface area is
... A = (√3)(4 in)² = 16√3 in²
Answer:
0.78814
Step-by-step explanation:
We solve using z score
z = (x-μ)/σ, where
x is the raw score = 4.0 inches
μ is the population mean = 4.4 inches
σ is the population standard deviation = 0.5 inches
z = 4.0 - 4.4/0.5
z = -0.8
Probability value from Z-Table:
P(x<4.0) = 0.21186
P(x>4.0) = 1 - P(x<4.0)
= 1 - 2.1186
= 0.78814
The probability that the rod you chose will be greater than 4.0 inches is 0.78814.
