Answer:
7xy^2 - 2xy^2
Step-by-step explanation:
Subtracting 3xy² from 8xy² is 8xy² - 3xy² = 5xy²
And 7xy^2 - 2xy^2= 5xy²
Answer:
The sampling technique used is the systematic sampling.
Step-by-step explanation:
Systematic sampling as the name implies is the application of a system so select samples, like having a people in a line, and a system is used to select the sample, like counting one to three and picking every third person in the line.

The answer is -3 . Use the gradient formula y2-y1/x2-x1
Answer:
0.24 > 0.18
Step-by-step explanation:
Given that,
Bob's stack = 0.2m
Cal's stack = 0.24m
Pete's stack = 0.18m
To find?
A number sentence.
<em>A simple sentence is a string/collection of words that contain a subject and a verb whereas a number sentence is a sentence that consist of </em><em>mathematical operation</em><em> like +, -, /, * together with an equality such as =, <, >, and like a sentence it also tell a fact.</em>
<em> </em>So, the number sentence that compares cal's stack of cards to Pete's stack is
<h2>0.24 > 0.18</h2>

Answer:
Figure 1:
Area: 30m^2
Perimeter: 23.6m
Figure 2:
Area: 98.8km^2
Perimeter:56.5km
Step-by-step explanation:
Area is base x height.
To get the perimeter, add up all the sides.
Figure 1:
Area:
6x5=30m^2
Perimeter: 6+5.8+6+5.8=23.6m
Figure 2:
Area:
7.6x13 = 98.8km^2
Perimeter:7.6+15+20+13.9=56.5km
