WHAT ON EARTH IS THIS ANSWER

Mathematics
1 answer:
olga_2 [115]3 years ago
5 0

Answer:

Step-by-step explanation:

You can figure out the angle DBC by the alternate interior theorem. Angle DBC=56 degrees. You already figured out BD.

Since we know BD, BC, and the angle DBC we can use the Law of cosine to find CD

The law of cosine is

CD^2=BC^2+BD^2-2(BC)(BD)cos DBC

Plug in what we know

CD^2=18^2+12.1^2-2(18)(12.1)cos 56

CD^2≈228.8387

Find the square root to isolate CD.

CD≈15.1

Answer:

Option d) 840

Step-by-step explanation:

Given that a test to measure psychotic tendencies was given to a group of 1,000 air force cadets who wished to work in nuclear silos.

If Score ≥64 would be eliminated.

X is N(52, 12)

Probability for any random person to get eliminated

=P(X\geq 64)\\= 1-R(64)\\=1-0.8413\\= 0.1587

Now coming to sample size of 1000 people, we find each person is independent of the other and there are two outcomes either >64 or < 64

So Y no of persons who get more than 64 is binomial with n =1000 and p = 0.1587

Mean of Y = E(Y)

= no of people who were not accepted =1000(0.1587) = 158.7

No of people accepted = 1000-158.7 = 841.3\\=841

Approximately we get 840 so option d

3. The values for p and q represent the equilibrium point. As related to the troupe's
svp [43]

Answer: The equilibrium point represents the raising or lowering the price in response to changes in the supply or demand.

If the price of a good is above equilibrium, this means that the quantity of the good supplied exceeds the quantity of the good demanded.

If the quantity is below the equilibrium point, it will create a shortage. because the quantity supplied is less than quantity demanded.

Hope this helps!
