Let’s first cut/separate this figure into two shapes: rectangle and a triangle
The area of the rectangle: 9 • 2 = 18
The area of the triangle: 1/2 • 8 • 4 = 16
The total area: 18 + 16 = 34
He needs 34 m square of grass
Answer:
a. 1.059
Step-by-step explanation:
Test statistics is used in hypothesis testing to find the conclusion. Test statistics are T-values which are used in testing a hypothesis and deciding whether to accept or reject the null hypothesis.
Test statistics can be calculated with the following formula:
Z = x - u / s /
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.
Answer:
21. An= 100 (2)^n-1
22. $51,200
23. n= 15
Step-by-step explanation:
21. 100, 200, 400, 800, 1600...
An= A r ^n-1
22. a10= 100(2)^10-1
a10= 100(2)^9
23. n=14
a14= 100(2)^14-1= 819200
n= 15
a15= 100(2)^15-1= 1638400
Answer:
