The speed of your ship in still water is 20 knots.Your ship traveled 70 miles downward in channel in the same amount of time it traveled 45 miles upward the channel.Calculate the rate of the channel current.
Define a variable, and write an equation. If x is the number of candy bars that Jason started with, x - (1/3)x - 3 = (11/30)x is an equation that can be solved to find the solution.
Difference of two squares: Example: x^2 - 9 factors to (x+3)(x-3) Perfect squares: x^2 + 6x + 9 = (x+3)(x+3) x^2 -6x + 9 = (x-3)(x-3) Cubes: x^3 - 27 factors to (x-3)(x^2 +3x +9) x^3 + 27 factors to (x+3)(x^2 -3x +9) Can you see the pattern?
This is definitly an error because Ho was rejected when it was true. Google Type I and Type II errors and you will find the definition of each and then you will be able to figure out which error happened here.
To find the range, substitute the values from the domain. Example: y = -3x + 4 y = -3(-3) + 4 = 9 + 4 = 13 y = -3(-2) + 4 = 6 + 4 = 10 So, we are finding the range of 13 and 10 s0 far
You want to use a two-tailed t-test. You do not want to use matched pairs. books set things up differently, but here is one way to do it.. group 1 = dog owners group 2 = no dog Ho: mu1 - mu2 = 0 Ha: mu1 - mu2 does not = 0 If you are allowed to use a statistics calculator (like...
use the law of cosines to start and find side c. Then use the law of sines to find remaining angles.
A 3 N weight slides down a ramp made of sandpaper. The coefficient of friction is 0.8, and the ramp is at an angle of 50° to the horizontal. How could you calculate the magnitude of the friction force? A. 3 N × sin(50°) B. 3 N × 0.8 × 50° C. 3 N &...
