Answer:
Matching Tiles with Terms:
Term Example
NOT a Representative Sample Drivers who reside in Middlefield
Population Residents of Middlefield
Representative Sample Residents randomly chosen from the
town register
Step-by-step explanation:
Population includes all the residents of Middlefield.
Representative Sample is a population subset that accurately reflects the characteristics of the population. For example, the subset of residents who are randomly chosen from the town register is an unbiased and representative sample.
NOT a Representative Sample: For example, drivers who reside in Middlefield do not represent the characteristics of the population of Middlefield.
To find the area you just find the area of each triangle.
To do this use the formula b×h×.5=A
6×4×.5=A
A=12
Now you just multiply 12 by 4. The reason you multiply by 4 is because you have 4 triangles that make up the rhombus. The area of the rhombus is 48cm²
The independent variable of an equation is x, or something u can change. in linear equations, for example, it is y=3x+4. and x is the independent variable cause most of the time u will plug in or substitute a number for x.
4sin x=2sin x + √3
4sin x-2sinx=√3
2sin x=√3
sinx=√3/2
x=arcsin √3/2=π/3 + 2Kπ U 2π/3+2Kπ
Sol: π/3 + 2Kπ U 2π/3+2Kπ ; K∈Z
π/3+2Kπ=60º+360ºk
2π/3+2Kπ=120º+360ºK
Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° = 
= 
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x = 
≈ 61.8 ( to the nearest tenth )
