Option c is correct
Step-by-step explanation:
Sampling error occurs when you are biased at sample selection when make some individuals less likely to be included in the data thereby miss representing the entire population.
Answer:
Since we want to satisfy both at the same time, "x" must be equal or greater than 6.
Step-by-step explanation:
This product is formed by two square roots, since this mathematical operator can only be defined for positive values and zero, the number inside the root must be always greater or equal to 0, on both roots. Therefore:

and

Since we want to satisfy both at the same time, "x" must be equal or greater than 6.
The sum of angles inside a triangle is the sum of angles 1, 2 and 3, which form a straight line, therefore 180 degrees.
The sum of the exterior angles
angle exterior angle
1 2+3
2 1+3
3 1+2
total 2+3+1+3+1+2=2(1+2+3)=2(180)=360 degrees.
Water freezes at 32 degree Fahrenheit.
Step-by-step explanation:
Given,
Formula for Celsius to Fahrenheit = 
x = Celsius temperature
Boiling point of water = 0°C
We will put x=0
0°C = 
0°C = 0+32
0°C = 32 degree Fahrenheit
Water freezes at 32 degree Fahrenheit.

Answer:
144500
Step-by-step explanation:
(1.7 x 10^4) x (8.5 x 10^-2)
= (1.7 x 10000) x (8.5 x 0.01)
=( 17/10 x 10000/1) x (17/2 x 1/100)
=17000/1 x 17/200
=289000/2
=1445000
