<span>This would be a bell curve with a z-score of greater than +2.00, since 3 minutes is exactly two standard deviations greater than the mean of 2.00. Looking at a z-score table for the proportion of the curve that lies in the 1-tailed area greater than 2.00, we find that the value is .0228. This would be the probability that the conversation is over three minutes: 0.0228 or 2.28%.</span>
HELLO EVERYONE,
TO FIND Y:
We know
a straight line makes an angle of 180
so,
180 = 119-y
180-119 = y
therefore y is
y = 59 degrees
TO FIND X:
We know,
all angles of a quadrilateral make a sum of 360,
so,
A+B+C+D = 360
HERE,
A = 131
B = 56
C = Y = 59
D = X
131 +56+59+X = 360
360 - 246 = X
X = 114 Degrees
Please do mark me the branliest if it helpful for you. Thanks.
Lets use bedmas/pemdas, and simplify the equation to find n.
n = 9 * 27 + 2 * 31 - 28
n = 243 + 2 * 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277
Therefore n = 277.

Answer:
3V
r = ∛ ( ---------- )
4π
Step-by-step explanation:
Please, enclose the fraction 4/3 inside parentheses, to eliminate any possibility of misreading this fraction. Also note that this formula MUST include "pi," symbolized by π.
V = (4/3) π r³ This formula does NOT include "m," which is a unit of measurement, not a variable.
Our task is to solve this formula for the radius, r.
Divide both sides by (4/3) π, to isolate r³. This results in:
v (4/3) π r³
------------- = -----------------
(4/3) π (4/3) π
V 3V
Then r³ = -------------- = --------
(4/3) π 4π
and r is found by taking the cube root of the above result:
3V
r = ∛ ( ---------- )
4π
