Which type of data (discreet, continuous, nominal, ordinal) from each of the following survey question are collected a) Name you

Anit [1.1K]

Answer:

a) nominal b) discrete c) ordinal d) continuous e) discrete

Step-by-step explanation:

a) The name of my favorite pet is only a "label" between the set of different names, in general there is no order, i.e., objectively we can't say that one name is better than other.

b) To find this answer we should do a counting process, i.e., if a random variable represents the number of times that I changed my residence in the past five years, possible values are 0, 1, 2, ...

c) Here we can say there are levels of preference, we can observe an order, but we can't measure the distance between different levels of preference.

d) To obtain an answer to this question we should do a measurement process, instead of a counting process, that is why this kind of data is continuous. A possibility could be for example 1.75m (m=meters), in other words, the random variable associated to this question can take any value in an specified interval.

e) Here we can get an answer through a counting process again, in other words, if Y is a random variable that represents the number of bedrooms in a house, in theory, Y can take the values 0, 1, 2, ...

Solve for x. a=1/2h(b x)

fredd [130]

A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b

starting from 1.4 miles away a car drives towards a speed check point and then passes it the car travels at a constant rate of 5

LenKa [72]

Answer: At t=0.015 hours when the car 0.6 miles from the check point.

Step-by-step explanation:

Since we have given that

Distance traveled by him towards a speed check point = 1.4 miles

Speed at which he is travelling = 52 miles per hour

Let the time taken by him be x

Since we have the equation

$d=1.4-52t$

where d denotes distance

and t denotes time.

If we have given that the car 0.6 miles from the check point.

So, we put the value of d in place of it .

$0.6=1.4-52t\\\\0.6-1.4=-52t\\\\-0.8=-52t\\\\0.8=52t\\\\\frac{0.8}{52}=t\\\\0.015=t$

So, at t=0.015 hours when the car 0.6 miles from the check point.
