The minute hand of a clock is 3 inches long. How far does the tip of the minute hand move in 40 minutes​?
Mkey [24]

Answer:

  4π in ≈ 12.57 in

Step-by-step explanation:

One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...

  s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in

Molybdenum rods are produced by a production line setup. It is desirable to check whether the process is in control, i.e. equal
ikadub [295]

Answer: Test statistic = -8 and rejected region is  (-∞,-1.966) and (1.966, ∞)

Step-by-step explanation:

Since we have given that

X is the length of a rod.

Sample Mean = 2 inches

Standard deviation = 0.5 inches

n = 400

Hypothesis are

H_0:\mu=2.2\\\\H_1:\mu\neq 2.2

Test statistics would be

t=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}}\\\\t=\dfrac{2-2.2}{\dfrac{0.5}{\sqrt{400}}}\\\\t=-8

Degrees of freedom = n-1 =400-1 =39

and \alpha =0.05\\\\\dfrac{\alpha }{2}=\dfrac{0.05}{2}=0.025

Using the t-distribution table, we get that critical value z = 1.966

Since the two tail test will be applied to this,

So, the acceptance region will be (-1.966, 1.966)

Hence, the rejected region will be (-∞,-1.966) and (1.966, ∞)
