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%
9,909.94 that is the answer
A. 1/3 is equivalemt to 0.3
Answer
1.8/125 cm³
2. 13
3a. x³-17
3b. 3x-5
5. A) Power
Step-by-step explanation:
1. (2/5)³= 2/5 * 2/5 * 2/5
= 4/25 *2/5
=8/125
2. b³+(10-a)
= (2)³ + (10-5)
=(2*2*2) + (5)
= 8 + 5
= 13
3a. a number cubed = x³
seventeen less than = -17
3b. three times a number = 3x
five = 5
5. product is when two values are multiplied (13 and 3+x)
The angles m∠x = m∠y because alternate interior angles are equal.
<h3>What is a
parallelogram?</h3>
A parallelogramis a quadrilateral in which opposite sides are equal and parallel to each other.
The opposite angles are also congruent, whereas consecutive interior angles are supplementary.
In the quadrilateral ABCD:
m∠x = m∠y (alternate interior angles are equal)
The angles m∠x = m∠y because alternate interior angles are equal.
