Answer:
171
4 numerical variables (Sepal Length ; Sepal Width ; Petal Length ; Petal Width)
All four numerical variables are continous.
Step-by-step explanation:
Number of cases = Number of species * number of flowers per species
Number of cases = 3 * 57 = 171 cases
B.) Numerical variables are those variables which are quantitative in nature, that is they are made of numbers which are capable of being used for mathematical computation in a dataset such as maximum, minimum, mean and slither statistical measures.
C.) All for variables are continous as they are capable of taking up unlimited number of values within its range, including decimal values. Hence they are not finite. Continous numberical variables include, length, height, width and as given in the scenario below, they are all continous.
The probability of not winning would be :
1 - probability of winning
This is written as:
1 - n/n+3
Now to simplify as a single fraction rewrite as:
N+3/n+3 - n/n+3
Simplify to get : 3/n+3
5

3/3 would be your answer in exact form.
Answer: m<Z = 79
Step-by-step explanation:
180 - 22 = 158
158/2 = 79
