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.
Using proportions, it is found that 68 more people prefer vanilla than do strawberry.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching this problem on the internet, it is found that, out of 400 people:
- 18% preferred strawberry.
Hence the amounts are:
The difference is:
140 - 72 = 68.
68 more people prefer vanilla than do strawberry.

Answer:
77
Step-by-step explanation:
c + 103 = 180
180- 103 = 77
c and b = 77
Answer:
19 units
Step-by-step explanation:
use distance formula: d = 
x₂ = 10
x₁ = -1
y₂ = 6
y₁ = 6
now plug in
A) 8 makes 343_ divisible by 9 because if you divide 3438 by 9 you get 382
