I don’t know if I’m right but I’m guessing B
Answer:
r₂ = 1.5 ft
t = 0.75 s
Explanation:
W = 4 lb ⇒ m = W/g = 4 lb / 32.2 ft/s² = 0.12 slug
v₁ = 6 ft/s
r₁ = 3 ft
v₂ = 12 ft/s
r₂ = ?
t = ?
vr = 2 ft/s
Conserving angular momentum we have:
m*v₁*r₁ = m*v₂*r₂ ⇒ r₂ = v₁*r₁ / v₂
⇒ r₂ = (6 ft/s*3 ft) / (12 ft/s) = 1.5 ft
Now, we get the time as follows:
vr = <em>d</em> / t ⇒ t = <em>d</em> / vr
where <em>d</em> is
<em>d</em> = Δr = r₁ - r₂ = 3 ft - 1.5 ft = 1.5 ft
finally
t = 1.5 ft / 2 ft/s
⇒ t = 0.75 s
Answer:
Binomial Function
I got my output using the formula = 1 - BINOMDIST (17, 50, 0.3, TRUE)
Then got the cumulative probability distribution at 17 to be 0.2178
Explanation:
To draw a normal distribution:
1. Got to '@risk' and click on 'defined distribution'
2. Select 'binomial' in function block
3. enter formula in cell formula and click okay
The use of @RISK to draw a binomial distribution of 50 trials and probability of success as 0.3 by entering formular =RISKBINOMIAL (50, 0.3).
Yes that is right no matter what you are talking about I’m not sure tho
