Answer:
The correct answer is 17 kilometers.
Step-by-step explanation:
Let A denote the point where the airport is located.
Newberg is located 8 kilometers due north of airport say at point B.
Summer field is located 15 kilometers due east of the airport say at point C.
Thus ABC is the required right angled triangle with sides AB = 8; AC = 15; and ∠A = 90°.
Thus we use Pythagoras theorem to find the value of the side BC which indeed would give us the distance between Newberg and Summer field.
∴ =
=
= 17 kilometers.
Thus the distance between Newberg and Summer field is 17 Kilometers.
Answer:
0.25
Step-by-step explanation:
Given that a recently married couple are planning to have four children. They are equally likely to have a boy as well as a girl.
Let X be the no of boys the couples have. X has two outcomes with p = 0.5
X is binomial with n = no of trials = 4 and p =0.5
the probability that they will have three boys and one girl
=
Reqd prob = 0.25
