Hoochie [10]

Answer:

5mm

Step-by-step explanation:

using the formula of volume of cone i.e. 1/3 ×πr²h

1/3 × πr²h = 314

or, r²= (314×3)/ (π×h)

or, r² = 25

r= 5 mm

A manufactured product has a length that is normally distributed with a mean of 12 cm. The product will be unusable if the lengt

Sav [38]

Answer:

a) σ = 0,1612

b) P [ 11,75 < X < 12,35] = 0,92,44 or 92,44 %

Step-by-step explanation:

NOTE: I assume the unusable length s 11,5 and less

a) For a normal distribution, the probability of P = 0,01 corresponds to z(score) = -3,1 then:

- 3,1 = ( X - μ₀ ) / σ

- 3,1 = (11,5 - 12 )/ σ

-3,1 = - 0,5 / σ

σ = 0,1612

b) If σ = 0,1612

P [ 11,75 < X < 12,35]

z₁ (score) = ( 11,75 - 12 ) / 0,1612

z₁ = - 0,25/ 0,1612

z₁ = -1,55

From z table P [ 11,75 < X] = 0,0606

z₂ (score) = ( 12,35 - 12) / 0,1612

z₂ = 0,35 / 01612

z₂ = 2,17

From z table P [ X < 12,35] = 0,9850

Finally P [ 11,75 < X < 12,35] = 0,9850 - 0,0606

P [ 11,75 < X < 12,35] = 0,92,44 or 92,44 %

Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of

Akimi4 [234]

Refer to the diagram shown below.

Let d = the horizontal distance from Charlie to the plane.
By definition,
tan(32°) = 1694.8/d
1694.8/d = 0.6249
d = 1694.8/0.6249 = 2712.2 ft

Answer: 2,712.2 ft
