Well, it depends. If you take one, do you leave it out, or put it back?? If you leave the ball in, then the probability would be 0.05419228% or 32/59049 but if you put the ball out of the urn, then the probability would be <span>0.211640211% or 32/15120. YOU'RE WELCOME :)</span>
Answer:
2.31 ft/sec
Step-by-step explanation:
In the picture attached, a representation of the problem is shown, where w(t) is the walking distance (as a function of time) and s(t) is the position of the tip of her shadow (as a function of time).
We want to find the derivative of s(t).
From triangles similarity:
s(t)/5 = [w(t) + s(t)]/18
18s(t) = 5w(t) + 5s(t)
13s(t) = 5w(t)
w(t) = 13/5*s(t)
We know that her speed is 6 ft/sec, that is:
d(w(t))/dt = 6 ft/sec
From the previous relationship:
d(w(t))/dt = 13/5*d(s(t))/t
Replacing:
6 = 13/5*d(s(t))/t
d(s(t))/t = 5*6/13
d(s(t))/t ≈ 2.31 ft/sec
Answer:
-4(8x-7)/7
Step-by-step explanation:
1. Simplify Term.
-8/7 (4x) - 8/7 * -3 + 4/7
-32x/7 - 8/7 * -3 + 4/7
-8/7 * 3
-32x/7 + 24/7 + 4/7
2. Simplify Term.
−
32
x * 24 + 4 divided by 7
-32x + 28 divided by 7
4(-8x + 7) divided by 7
4(-(8x) + 7) divided by 7
3. Rewrite 7 as -1(-7)
4(-(8x) - 1(-7)) divided by 7
4(-(8x - 7)) divided by 7
4. Rewrite -(8x - 7) as -1(8x - 7)
4(-1(8x - 7)) divided by 7
-4(8x - 7)/7
Answer:
h = (m/4 - as)/s
Step-by-step explanation:
s = m / 4(a+h)
(a+h) · s = m/4 ><em>multiplied </em><em>(a+h)</em><em> on both side</em>
as + hs = m/4 ><em>distributed the </em><em>s</em><em> to </em><em>(a+h)</em>
hs = m/4 - as ><em>subtracted </em><em>as</em><em> on both side</em>
h = (m/4 - as)/s<em> >divided </em><em>s</em><em> on both side</em>
<em />
Answer:
1/4
Step-by-step explanation:
1/2 = 2/4
3/4-2/4=1/4
