VARVARA [1.3K]

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

z=\frac{x-272}{9}

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

272-0.84*9\\= 264.44

Less than 264.44 days would be for the shortest 20%

Can some one please help me
Tasya [4]

Given:

A figure of a right triangle with perpendicular 500 m  and hypotenuse x.

To find:

The value of x.

Solution:

If a transversal line intersect two parallel lines, then alternate interior angles are congruent.

Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.

In a right angle triangle,

\sin \theta =\dfrac{Perpendicular}{Hypotenuse}

In the given triangle,

\sin 40^\circ =\dfrac{500}{x}

x=\dfrac{500}{\sin 40^\circ }

x=\dfrac{500}{0.6427876}

x=777.8619

Round the value to the nearest tenth.

x\approx 777.9

Therefore, the value of x is 777.9 m.
