In using the "2 to the k rule" to determine the number of classes for a frequency distribution, what is the meaning of the variable k? Multiple choice question. k is the greatest number of classes such that 2k

k is the smallest number such that 2(to the k)>n

Step-by-step explanation:

Frequency distribution is defined as the number of times the value occurs. It contains the class interval as well as the corresponding frequencies. A pivot table is used to represent the frequency distribution.

The "2 to the k" rule states that 2 to the power k should be less than equal n, where n is the number of the given data points. It should be the smallest number.

Thus the answer is : k is the smallest number such that 2(to the k)>n.

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
