Answer:
nope
Step-by-step explanation:
Water is tasteless and odorless
Answer:
Less than 264.44 days would be for the shortest 20%
Step-by-step explanation:
Given that X, the length of a human pregnancy is normally distributed with a mean of 272 days with a standard deviation of 9 days (Bhat & Kushtagi, 2006).
X is N(272, 9)
Corresponding Z score would be for any x
We have to find out the shortest 20%
Corresponding z score i.e. z score 20th percentile is given by
-0.84
corresponding x score is
Less than 264.44 days would be for the shortest 20%
Length of bridge = 53 meters
Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)
Let length of bridge at any given time be 'a'
As an absolute value equation, the situation can be expressed as:
⇒ |a-53| < 0.021
Solving the equation
⇒ -0.021 < a-53 < 0.021
⇒ 53 - 0.021 < a < 53 + 0.021
⇒ 52.979 < a < 53.021
Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
Volume of a sphere = (4/3) (pi) (radius)³
The sphere's volume is proportional to the cube of its radius,
so the radius is proportional to the cube-root of the volume.
The only way to double a sphere's volume is to increase
its radius by the factor of
∛2 = 1.26 (rounded).
