The total length of the border = 50.2 yards
Step-by-step explanation:
Step 1 :
Given,
Diameter of the circular region = 16 yards
We need to compute the total length of the border.
Step 2 :
The total length of the border can be obtained by computing circumference of the region with the given diameter
Circumference = 2(pi)(r)
where r is the radius
here diameter = 16, so radius = 8 yards
Hence circumference = 2 (3.14) 8 = 50.24 yards
Step 3 :
Answer :
The total length of given border = 50.2 yards (rounded off to nearest 10th)
Answer:
a. Discrete
b. Discrete
c. Not a random variable
d. Continuous
e. Discrete
f. Continuous
Step-by-step explanation:
The discrete random variable is countable while continuous random variable is measurable.
a. The number of fish caught is a discrete random variable because these are countable.
b. The number of text book authors are also countable so it is a discrete random variable.
c. The political party affiliation of adults is not a random variable because the political party affiliation depends on person's interest and it cannot be randomly assigned to person. Also random variable is the numerical outcome of random experiment whereas political affiliation is the categorical variable that results in non numerical responses such as Democrat, Republicans etc.
d. The square footage of a house is measurable and so it is a continuous random variable.
e. The number of free dash throw attempts are countable so it is a discrete random variable
f. The weight of Upper T dash bone steak is measurable and so it is a continuous random variable.
Check the picture drawn
Consider the line segment AB,
let M be the midpoint of AB, so AM=MA
erect the perpendicular MT to AB from point M. Pick a point P on MT and join it to the points A and B
The triangles PMA and PMB are congruent from the Side Angle Side congruence postulate:
AM=MA, PM is common and m(PMA)=m(PMB)=90°, as MT is perpendicular to AB
so PA=PB
