Answer:
The answer to this question is D: None of the above
Step-by-step explanation:
From the example given in the question, this is a bad way of data sampling. The example in the question is a typical Voluntary response sample. In this type of sampling, the researcher creates a request as the case may be in the example through television, and ask for members of a population to join. Thus people then choose to be part of the sample or not. In this type of sampling, the respondents tend to have alike opinion in contrast to the rest of the population. This therefore makes voluntary response sample kind of bias.
Answer:
The solution of the system of inequalities is the region above the right line y=(1/4)x+6 to the left of x=4; and above the right line y=2x-1 to the right of x=4
Step-by-step explanation:
The inequality y>(1/4)x+6 is the area above the right line y=(1/4)x+6
For x=0→y=(1/4)(0)+6→y=0+6→y=6; Point=(x,y)→Point=(0,6)
For x=4→y=(1/4)(4)+6→y=1+6→y=7; Point=(x,y)→Point=(4,7)
The inequality y>2x-1 is the area above the right line y=2x-1
For x=0→y=2(0)-1→y=0-1→y=-1; Point=(x,y)→Point=(0,-1)
For x=4→y=2(4)-1→y=8-1→y=7; Point=(x,y)→Point=(4,7)
Graphing the right lines (see the attached file), we can see the solution of the system: The region above the right line y=(1/4)x+6 to the left of x=4; and above the right line y=2x-1 to the right of x=4
Answer:
See Below
Step-by-step explanation:
You want to find AB.
They give the equation for AB, BC, and AC
AC - BC = AB
substitute the equations
(30) - (8x + 3) = 6x + 8
30 - 8x - 3 = 6x + 8
27 - 8x = 6x + 8
+8x +8x
27 = 14x + 8
-8 -8
19 = 14x
19/14 = 14x/14
1.3571428 = x
0.1 = tenth
1.4 = x
Substitute x into the equation for AB
6(1.4) + 8
16.4
Answer:
1/3 , only one solution
Step-by-step explanation:
3x-1 = 1-3x
3x-1 = -3x+1
6x-1 = 1
6x = 2
x = 1/3
