Answer:

The probability of exercise in cruise ships = 73

Step-by-step explanation:

Let A be the probability of rock climbing

Let B be the probability of ice skating

Let C be the probability of fitness center

P(A) = 36, P(B) = 44, P(C) = 27

P(A ∩ B) = 14, P(A ∩ C) = 11, P(B ∩ C) = 9

P(A ∩ B ∩ C)=0

By formula,

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B) − P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C).

Substituting the values in the above formula,

P(A ∪ B ∪ C) = 36 + 44 + 27 - 14 - 11 - 9 + 0

  = 107 - 14 - 11 - 9

P(A ∪ B ∪ C)  = 73

lutik1710 [3]

Answer: RS

Step-by-step explanation:

A greater angle of a triangle is opposite a greater side. If angle Q is greater than angle R, then side RS is greater than side QS.

Because Q is the larger angle in the triangle, Then RS is the longest side.

Natali [406]

Given :

A sailor is 30 m above the water in the crow's nest on a sailboat.

The sailor encounters an orca surface at an angle of depression of 15 degrees.

The crows nest is 20 m horizontally from the bow (front) of the boat.

To Find :

How far in front of the boat is the orca.

Solution :

Let, distance of boat front from the crow's nest is x.

So,

\dfrac{30}{20+x}=tan \ 15^{\circ}\\\\x=\dfrac{30}{tan \ 15^{\circ}}-20\\\\x=111.94-20\\\\x=91.94\ m

Hence, this is the required solution.

The average rate of blood flow is given by

\displaystyle\frac1{R-0}\int_0^Rv(r)\,\mathrm dr=\frac kR\int_0^R(R^2-r^2)\,\mathrm dr
=\dfrac kR\left(R^2r-\dfrac13r^3\right)\bigg|_{r=0}^{r=R}
=\dfrac kR\left(R^3-\dfrac13R^3\right)
=\dfrac{2kR^2}3
