Answer:

a) Discrete random variable

b) Not a random variable

c) Discrete random variable

d) Continuous random variable

e) Discrete random variable

f) Continuous random variable

Step-by-step explanation:

a) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

b) This is not a random variable because hair color is quality, thus it cannot be quantify.

c) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

d) This is continuous random variable because we can quantify it, it can take decimal number and has no true zero. For instance, 0 degree Celsius does not implies absence of temperature. Or that we say someone is a dwarf does not implies he/she has no height even though the measure scale may read zero.

e) This is discrete because we can quantify it and it can not take a decimal number and has true zero. That is, zero means absence.

f) This is continuous random variable because we can quantify it, it can take decimal number and has no true zero. For instance, 00:00 GMT does not implies absence of time.

VladimirAG [237]
After the first, we have 2/3 left, the second and third took 1/6 and 1/4, or 5/12 (1/6+1/4=2/12+3/12=(2+3)/12=5/12). Now, we just subtract 5/12 from 2/3, so 2/3-5/12=8/12-5/12=(8-5)/12=3/12=1/4. This means we have 1/4 of an hour left.

Answer:

So, cows heart best is faster than horse.

Step-by-step explanation:

Time and heartbeats are in direct proportion.

   p = kx

Where p is the beats per minute and x represents time in minutes

Now, to find the value of k, substitute p = 152 and x = 4

152 = 4k

  k = 152/4

  k = 38

\sf \boxed{p = 38x}

Cow:  y = 65x

So, cows heart best is faster than horse

Yanka [14]

Answer: 33.33%

Step-by-step explanation:

Number of White sneakers = 8

Number of Black sneakers = 10

Number of Blue sneakers = 10

The percentage of Oscar's sneakers that are black will be:
