Which of the following is an example of a continuous random variable?
matrenka [14]

Answer:

The weight of a bag of potatoes.

Step-by-step explanation:

Continuous variable are those which can take infinite number of value between any two values.

For example: amount of sand : it can take any value  let say between 100 and 101 kg. Such 100.1 kg,  100.888 kg and so on.

Discreet variable are those which takes values which can take on natural number values such 1,2 , and so on.

Example : no of students of class:  no. of students can only be natural numbers  like 45, 35 and so on

_________________________________________________

lets evaluate options now

a. The number of cars in a parking lot.--> it is Discreet variable as no. of cars can be in terms of natural numbers

_______________________________

The weight of a bag of potatoes. it is continuous variable as weight can take infinite set of values like 200 kg, 200.11 kg, 200. 111119 kg and etc.

__________________________________________

The number of repairs at a computer shop over the course of the week.

--> it is Discreet variable as number of repairs will also vary in natural number form like 10 repairs, 20 repairs etc. there cannot be 10. repairs.

_______________________________________________________

d. The total runs scored in a cricket game

---> It is Discreet variable as number of runs scored is also natural number like 251 runs, 301 runs. Runs cannot be 300.2 runs.

_____________________________

Hence, correct answers is  

The weight of a bag of potatoes.

A metal cube contracts when it is cooled. if the edge of the cube is decreasing at a rate of 0.2 cm/hr, how fast is the volume c
aleksandr82 [10.1K]

Answer:

2160 cm³/hour

Step-by-step explanation:

By default, we know that the volume of a cube is given as s³

Thus, the Volume function, V = s³

When we differentiate with respect to time we have

dV/dt = 3s² (ds/dt), where ds/dt = 0.2

Then we go ahead and substitute all the given parameters

dV/dt = 3 x 60 x 60 x 0.2

dV/dt = 10800 * 0.2

dV/dt = 2160 cm³/hour

This means that the volume decreases by a rate of 2160 cm³/hour at the instant its edge is 60 cm

Consider the radical equation √c+22 = c + 2.
dimulka [17.4K]

First square both sides to get:

c + 22 = (c + 2)^2

or

c + 22 = c^2 + 4c + 4

Move the terms on the left side to the right side:

c^2 + 3c - 18 = 0

Factor to get:

(c + 6) * (c - 3) = 0.

The solutions are c = -6 and c = 3.

Check to see if these answers work by plugging them into the original equation:

c = -6:

sqrt (-6 + 22) ?= -6 + 2

But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.

c = 3:

sqrt (3 + 22) ?= 3 + 2

5 = 5. So, 3 works.

The answer is: B
