Step-by-step explanation:
first set of data will give greater standard of deviation
The scientific notation is a method that scientists use
to easily handle very large numbers or very small numbers. As an example,
instead of writing down the value 0.0000000065, we write the value 6.5 x 10-9
in scientific notation. The number of places the decimal point got moved
becomes the exponent of the number 10. When the movement is from left to right,
the exponent is negative (for very small numbers). When it is right to left,
the exponent is positive (for very large numbers).
Therefore writing estimated measurements in scientific
notation:
length of a grain of salt : 0.0002 centimeters = 2 x 10-4
centimeters
width of a key ring : 0.02 centimeters = 2 x 10-2
centimeters
Answer:
This is a function because each x value has a different y value. If one of x values would of had two different y values then it would of not have been a function
Step-by-step explanation:
45x = 180
divide by 45
x=4
yes
420 /d = 30
multiply by d
420 =30d
divide by 30
14 =d
no d=14
37+s = 80/2
37+s =40
subtract 37 from each side
s =3
no s=3
52+g =45+11
52+g = 56
subtract 52 from each side
g=4
no g=4
13+14 = 3f
27 = 3f
divide by 3
9=f
yes f=9
Answer:
Greater.
Step-by-step explanation:
The in the function 
, the square root term 
has to give a real number if 
is to be real. This can only happen if 
because if 
then will give a complex number and therefore will not be real.
Thus, the domain for f(x) is all real numbers<em><u> greater</u></em><u> </u>than or equal to 2.
