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.
3x^4 + 2x^2 - 7x + 5...hope that helps
Given: lines l and m are parallel, and line t is a transversal.
angle pair result/justification
1 and 2 are equal (vertical angles)
6 and 8 are equal (corresponding angles)
1 and 4 are equal (alternate exterior angles)
4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)
Note:
alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.
If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)
If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)
Answer:
2x 2y -1
Step-by-step explanation:
x plus 1x equals 2x and 2y equals 2 y and 1 plus 1 minus 3
Answer:
plug in 2 everwhere you see a variable
