In October, average temperatures at the base camp of Mount Everest are about (-10) degrees Celsius. Average temperatures during the same month at the summit of Mt. Everest are about (-27) degrees Celsius. About how many degrees warmer is it at the base camp?

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.

i think you need to show more to answer this question

you must evaluate the function f first.   division by 0 is undefined. therefore, the composition cannot be evaluated.
