Answer:
C.
In a regular hexagon, the length of the radius is the same as the length of a side.
Step-by-step explanation:
A regular polygon is the polygon which have equal sides. Any regular polygon can be considered as a arrangement of the same number of equilateral triangles ad the number of sides.
For example, a regular hexagon ( 6 sized polygon) is made of the 6 equilateral triangles as shown in the image below.
Thus, the radius (which is the distance of the center of the polygon to any corner of it) is equal to the length of a regular polygon as it is composed of equilateral triangles.
So, option C is correct.
Answer: 0.5
Step-by-step explanation:
Given : Adult male heights have a normal probability distribution .
Population mean :
Standard deviation:
Let x be the random variable that represent the heights of adult male.
z-score :
For x=70, we have
Now, by using the standard normal distribution table, we have
The probability that a randomly selected male is more than 70 inches tall :-
Hence, the probability that a randomly selected male is more than 70 inches tall = 0.5

Step-by-step explanation:
This question is incomplete; find the complete question in the attachment.
Given curve is modeled by the quadratic equation,
y = x²
If the curved pit is shifted 2 units down,
Equation of the translated curve will be,
y = x² - 2
If the curved pit is translated (shifted) by 2 units left,
Equation of the new curve will be,
y = (x + 2)²
If the curved pit is shifted by 2 units right,
Equation of the translated curve will be,
y = (x - 2)²
If the curved pit is shifted 2 units up,
Equation of the translated curve will be,
y = x² + 2
