Determine the measure of angle bpc in the figure

Tju [1.3M]

From the last answer
angle CPD = 38°
agian,
angle BPC + angle CPD = 90° ( sum of complementary angles)
or, angle BPC + 38 = 90
or, angle BPC = 90 - 38
or, angle BPC = 52°
therefore BPC = 52

Lunna [17]

Answer:

( - $\sqrt{3}$ /2 , -1/2)

Step-by-step explanation:

-210 degrees in standard position corresponds to an angle in the 3rd quadrant 30 degrees below the negative x-axis

The hypotenuse of the triangle here is 1, and we want the coordinates.

A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.

11111nata11111 [884]

Answer:

56.7 mi/h

Step-by-step explanation:

The formula for average speed is:

Average Speed = $\frac{TotalDistance}{TotalTime}$

Thus we have:

Average Speed = $\frac{210+130}{3.5+2.5}\\=\frac{340}{6}\\=56.66$ mph

<em>Rounding to the nearest tenth, we have </em>

Average Speed = 56.7 mi/h

For a group of 100 people, compute(a) the expected number of days of the year that are birthdays of exactly 3 people.(b) the exp

Scilla [17]

Answer:

Step-by-step explanation:

Leaving leap years, a year contains 365 days.

For a group of 100 people, each person is independent of the other and probability of any day being his birthday has a chance of

$\frac{1}{365}$

a) Probability that exactly 3 people have same birthday = $\frac{1}{365^3}$

Each day is independent of the other

And hence no of days having exactly 3 persons birthday out of 100 persons is binomial with n = 365 and p = $\frac{1}{365^3}$

Expected value of days = np = $\frac{1}{365^2}$

b) Distinct birthdays is binomail with p =1/365 and n = 365

Hence

expected value = np =1
