Answer: 4.54%
Step-by-step explanation:
The binomial probability formula :-
, where P(x) is the probability of getting success in x trials, n is total number of trials and p is the probability of getting succes in each trial.
Given : The proportion of college freshmen majoring in business said that "to get training for a specific career" was a very important reason for their going to college :
Now, if six freshman business majors selected at random, then the probability that no more than two of the six freshmen in the group felt that this reason was very important. :-
Hence, the probability that no more than two of the six freshmen in the group felt that this reason was very important= 4.54 %

Answer:
The anchor should be located at the midpoint between the 20m high and 60m high antennas.
Step-by-step explanation:
Let the length of cable for 20m high antenna be represented by x, and that for 60m high antenna be y.
The single length of cable required = x + y.
From the principle of geometry, if the cable is anchored at 200m from the 20m high antenna, it forms a right angled triangle. Applying the Pythagoras theorem,
x =
= 199
Applying the same principle to the 60m high antenna gives,
y =
= 191
The single length of cable required = 199+ 191
= 390m
Varying the point of location of the anchor between the two antennas causes an increase in the length of cable required.
The anchor should be located at the midpoint between the two antennas to achieve a minimum amount of cable.
