Which of the following is the measure of angle RCP?
enyata [817]

Answer:

From the information provided we have:

PD ≅ RD (= 11)

∠CPD ≅ ∠CRD (= 90°)

They both have CD as the hypotenuse.

=> ΔCPD ≅ ΔCRD

=> ∠PCD ≅ ∠RCD

Now we know that:

∠RCP = ∠PCD + ∠RCD

∠RCP = 2 · ∠RCD

∠RCP = 2 · 33° = 66°

So the answer is B

The number of people who use the ATM at night outside your local bank branch can be modeled as a Poisson distribution. On averag
Marina86 [1]

Answer:

0.6988

Step-by-step explanation:

Given that the number of people who use the ATM at night outside your local bank branch can be modeled as a Poisson distribution.

Let X be the number of customers arriving between 10 and 11 am.

X is Poisson with mean= 1.2

Required probability

=  the probability that in the hour between 10 and 11 PM at least one customer arrives

= P(X≥1)

=1-P(X=0)

=1-0.3012

= 0.6988

Suppose there were m married couples, but that d of these 2m. people have died, Regard the d deaths as striking the 2m people at
iren2701 [21]

The function that represents surviving people are X = 2m - d

Given that there are m married couples and d of the 2m of these couples have died, the total people that remain is expressed as:

Total people remaining = Total married couple - those that died

Total married couple = 2m

Total people that died = d

Taking the difference to get the remaining people;

Total people remaining = 2m - d

Hence the function that represents surviving people are X = 2m - d
