a tree is 3,212 years old. How can you express this age in scientific notation with the lowest level of precision?
3x10^3
3.2x10^3
3.21x10^3
3.212x10^3***
answers only for checking:)
1) D
2) A
3) A
4) B
5) C
6) B
7) A
i already did the quiz for all my CONNEXUS people
That is high precision.
For low I would pick 3*10^3
Bre is right as of 1/13/22 and thanks for the help.
dam are all of u like homeschooled...I have the same questions lmaoo
here are the answers for the scientific notation quick check U3L2
1.) 7.08 x 10^-8
2.) 6.1 x 10^-7
3.) 1.25 x 10^-4
4.) doubling n results in a doubling of the value of the expression.
5.) 2.45 x 10^5
6.) 4 x 10^12
7.) 3 x 10^3
your welcome
i just took the quick check here are my answers. 100%
1- 4.22 x 10^-3 (d)
2- 7.08x10^-8 (a)
3- 6.1x10^-7 (a)
4- 1.25 x 10^-4
5- doubling n results in a doubling of the value of the expression (c)
6- 2.45x10^5 (b)
lastly 7- 3x10^3 (a) (it may not seem that way, but most precision would be 3.212x10^3, so least would be 3x10^3. good luck!)
Oh ok, thank you.
zoie is right :)
To express the age of the tree, 3,212 years, in scientific notation with the lowest level of precision, we need to round it to just three significant figures. The first significant figure is 3, the second significant figure is 2, and the third significant figure is 1.
To convert this number into scientific notation, such that it has three significant figures, we move the decimal point after the first significant figure. This gives us a coefficient of 3.21. Since we are moving the decimal point three places to the right, we have a power of 10 of 3.
Therefore, the correct representation of the age of the tree in scientific notation with the lowest level of precision is 3.212×10^3.
