Jordan computed in a two-way table the relative frequencies of the weather on practice days and game days during his football season.

Weather During Football

Raining
Not Raining
Practices
23%
77%
Games
13%
87%

Which statement best describes the relationship between the two variables?
There appears to be an association because the relative frequencies by column are different.
There appears to be an association because the relative frequencies by row are different.
There does not appear to be an association because the relative frequencies by column are different.
There does not appear to be an association because the relative frequencies by row are different.

read the excerpt from “the blackfeet creation.”

what does this excerpt show about blackfeet culture?

the blackfeet prefer to eat cooked meat.

the blackfeet eat small game as well as buffalo.

the blackfeet believe that buffalo are sacred.

the blackfeet animals for providing them with food.

faith or loyalty when pledged in a solemn agreement or undertaking.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
