The cumulative distribution function for heights (in meters) of trees in a forest is . (a) Explain in terms of trees the meaning of the statement . tells us that of the trees in the forest have . (b) Which is greater, or

#See solution for details

Step-by-step explanation:

a.Given that the cumulative distribution function for heights is .

Also given the cumulative distributions F(7)=0.6

-F(7)=06 is signifies that  the fraction of trees less than 7 meters in height is 0.6  .

b .Which is greater, F(7) or F(6):

-We note that the cumulative distribution function increases with increasing values of .

-Hence F(7) is greater than F(6), , that is to say the the fraction of trees of height less than 7 meters is higher than the fraction of trees less than 6 meters.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
