decide whether the random variable x is discrete or continuous. x represents the length of time it takes to get to work
FromTheMoon [43]

The given variable is a continuous variable.

<h3>What is continuous variable?</h3>

A quantitative variable can be either continuous or discrete depending on whether it is normally obtained through measurement or counting. A variable is continuous over a range of real values if it can take on any two specific real values and all other real values in between.

<h3>What is mercury thermometer?</h3>

In Amsterdam, physicist Daniel Gabriel Fahrenheit created the mercury thermometer, also known as a mercury-in-glass thermometer. It consists of a glass tube with a small diameter and a mercury bulb attached to it; the bulb contains far more mercury than the tube does.

<h3>According to the information:</h3>

A mercury thermometer was used to take the subject's temperature.

Because of the temperature:

  • Not counting but measuring it.
  • You can use a decimal number to represent its value.
  • As a result, it is open to any value inside an interval.
  • Temperature is therefore a continuous variable.
  • The only format in which discrete values can be stated is as whole numbers.

so

Temperature is a continuous variable,

Calculate the mean deviation by median (by using the mid-point(x) of leaf weights. b) A fair die is rolled. Find the probability
SVETLANKA909090 [29]

Answer:

hello attached below is the required table that is missing and the completed table as well

A) mean deviation = 0.1645

B) 2/3

Step-by-step explanation:

From the table we calculated the midpoint value (x) and c.f

N = 27

median class = 2.35 to 2.45

median = l + [ (N/2) - cf / F ] * H

             = 2.35  + [ (13.5 - 13) / 6 ] *0.1 = 2.3583

hence mean deviation by median

= summation of  fi |xi -M| / summation of fi

= 4.4417 / 27 = 0.1645

B ) probability of getting an odd number or prime number or both

the probability of an odd number = 1/2

also the probability of an even number = 1/2

while the probability of getting neither of them = 1/3

hence the probability of getting odd or prime or both

= 1/2 + 1/2 - 1/3 = 2/3
