Answer:

Option B

Step-by-step explanation:

For a freely falling body or object the acceleration would be the acceleration due to gravity

This would vary depending on the system we choose.

If we choose m/sec ^2 i.e. metric system

acceleration due to gravity = $9.8m/sec^2$

In FPS system

acceleration due to gravity $= 32.17 ft/sec^2$

Out of 4 options we find that option B is right.

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 %

Fill in the blanks in questions 8 through 10.

SVEN [57.7K]

Answer:

Step-by-step explanation:

1 minute = 8 revolutions

x minutes= 360 revolutions

Divide 360 by 8

The wheel will make 360 revolutions in 45 minutes

Check your work:

If 45 minutes = 360 revolutions, and the wheel revolves 8 times per 1 minute, 8 revolutions x 45 minutes should equal 360 revolutions.

(it does)
