i can help with vectors, physics, and calculus if any one needs help with those
those are the only subjects i am confident in

If you divide power measured in watts (1 watt = 1 kg*m^2/s^3) by an acceleration expressed in m/s^2, in what units will the answer be expressed?
Use the fact that the speed of light in a vacuum is about 3.00 ✕ 10^{8} m/s to determine how many kilometers a pulse from a laser beam travels in exactly 3.8 hour(s).
How many significant figures are in the following measurements?
(a) 6000000 m/s
significant figures
(b) 5.00 ✕ 10^{8} m/s

does it make sense, i could explain if you want? dude why are there so many questions on the spoiler O_O
i will do the rest in 10000000 years

If someone could translate that into french i would have been able to help...please find the mean, median, and mode of this data set: 30, 37, 32, 39, 33, 34, 32
don't judge me
also how do u find mean again? my teacher went through the notes to fast for me to finish writing.

The value of the speed of light is now known to be 2.997 924 58 ✕ 10^8 m/s. Express the speed of light to each of the following levels of precision.
(a) with two significant figures
3.0 x 10^8 m/s
(b) with five significant figures
2.9979 x 10^8 m/s
© with six significant figures
2.99792 x 10^8 m/s
How many significant figures are there in the following measurements?

i am confused about this number why are there two decimals ?

A farmer measures the distance around a rectangular field. The length of each long side of the rectangle is found to be 18.33 m, and the length of each short side is found to be 19.4 m. What is the total distance around the field?
perimeter: 75.5 m
Estimate the number of tabletennis balls that would fit (without being crushed) into a room that is 2 m long, 2 m wide, and 12.0 m high. Assume that the diameter of a ball is 3.8 cm.
2.13 x10^6 tennis balls
Calculate the circumference and area for the following circles. (Use the following formulas: circumference = 2πr and area = πr^{2}.)
(a) a circle of radius 2.2 cm
C = cm
A = cm^{2}
^{circumference: 14 cm}
^{area: 15 cm^2}
(b) a circle of radius 6.60 cm
C = cm
A = cm^{2}
circumference: 41.5 cm
area: 137 cm^2
One cubic centimeter (1.0 cm^{3}) of water has a mass of 1.0 ✕ 10^{3} kg at 25°C. Determine the mass of 3.0 m^{3} of water at 25°C.

to find the mean
add everything together and divide by how many there are
30+ 37+ 32+ 39+ 33+ 34+ 32 =237
237/7 =33.9
what is this
i meant that i did them without taking 1000000 years
was too lazy to do all of them hehe, does it make sense though?

yea sureto find the mean

30+ 37+ 32+ 39+ 33+ 34+ 32 =237

What is a mean? We have totally different names in France...
it means to take an average of the numbers given; there mean, median, and mode which are the three different ways to do it
i think though mean is the most accurate
what are the names you use in France?
Posted 24 August 2015  03:31 PM

mean= average
idk why we have such a weird word for it though lol
Posted 24 August 2015  03:36 PM
Oooooh ok, a mean is "moyenne" and median is "médiane" and mode is "mode" but i can't remember how you calculate the mode...it means to take an average of the numbers given; there mean, median, and mode which are the three different ways to do it

The mode is just the most repeated number
so if the sequence is 3,5,2,5,7,8,5,9 the mode is 5

Oh ok thanksThe mode is just the most repeated number

The APUSH exam changed so some of those links may not be helpful.
Definitely add these:
