SAM now has 30ml of pop to share equally into glasses.

viva [34]

He can split his pop into in whole mLs any n glasses such that n is a divisor of 30, namely any n in {1,2,3,5,6,10,15,30}. The fraction in each glass is then 1/n.

Need help .... Regular octagon ABCDEFGH rotates 360 degree clockwise about it's center . After how many 45 increments will A' (

oksian1 [2.3K]

Answer:

If the octagon is clockwise, then after 5 times 45 increments A' will coincide with F.

If the octagon is counterclockwise, then after 3 times 45 increments A' will coincide with F.

Step-by-step explanation:

Case 1: Let the octagon is clockwise

It is given that a regular octagon ABCDEFGH rotates 360 degree clockwise about it's center.

There are 8 vertices and the central angle between two consecutive vertices is 45 degrees.

Central angle between AB is 45 degree.

Central angle between AC is

$\text{Angle between AB}+\text{Angle between BC}=45^{\circ}+45^{\circ}=2\times 45^{\circ}$

Central angle between AD is

$\text{Angle between AB}+\text{Angle between BC}+\text{Angle between CD}=45^{\circ}+45^{\circ}+45^{\circ}=3\times 45^{\circ}$

Similarly,

Central angle between AE is

$4\times 45^{\circ}$

Central angle between FA is

$5\times 45^{\circ}$

Therefore after 5 times 45 increments A' will coincide with F.

Case 2: Let the octagon is counterclockwise

$FA=AH+HG+GF$

$FA=45^{\circ}+45^{\circ}+45^{\circ}$

$FA=135^{\circ}$

$FA=3\times 45^{\circ}$

Therefore after 3 times 45 increments A' will coincide with F.

Determine whether the value is a discrete random variable, continuous random variable, or not a random variable. a. The number

AveGali [126]

Answer:

a) it is a discrete random variable

b) It is a continuous random variable

c) It is not a random variable

d) It is a discrete random variable

e) It is a discrete random variable

f) It is a continuous random variable

Step-by-step explanation:

Explanation,

Continuous Random Variable

A continuous variable is one that can take on an uncountable set of values.

It may take any values within an interval.

It can take infinite values within an interval.

They are obtained by measuring rather than counting.

Discrete Random Variable

These can only take a discrete value and cannot be expressed in the form of decimals.

They are obtained by counting rather than measuring.

a). it is a discrete random variable ⇒ as a number of people is a discrete count, which takes values such as 0 or 1 or 2.

b). The exact time it takes to evaluate 27+72 ⇒ Since, Time is measured and thus it is a continuous random variable.

c). The gender of college students ⇒ Gender is categorical data. It is neither continuous nor discrete.

d). The number of hits to a website in a day ⇒ Since the number of people cannot be expressed as decimals, thus it is a discrete random variable

e). The number of bald eagles in a country ⇒ Since the number of people cannot be expressed as decimals, thus it is a discrete random variable

f). The distance a baseball travels in the air after being hit ⇒ Distance is measured and thus it is a continuous random variable.
