A small country had a population of 2,254,000 people in the year 2012. If the population grows steadily

Anuta_ua [19.1K]

Step-by-step explanation:

year 2012 population = 2,254,000*3.5%

= 78.89

each year up to 2020

so 2020 - 2012 =8

78.89*8 = 631

total population at end of 2020 =2,254,000 + 631

= 2,254631

New codes to destroy the First Order are known to exist. With probability 0.6, the codes are hidden by Leia; with probability 0.

elixir [45]

Answer: (a). 0.62 (b). 0.53

Step-by-step explanation:

Let us start by defining some events seen:

Given;

L rep the event that codes hidden Leia

BB represents the codes hidden in BB-8

H is the event that codes hidden by Hah

C-3PO rep the codes hidden in C3PO

Giving the probabilities, we have that

P(L) = probability that codes are hidden by Leia = 0.6

P(H) = probability that codes are hidden by Hah = 0.4

where P(BB/L) = 70/10 i.e 70%

P(C-3PO/L) = 1 - P(BB/L) = 1 - 7/10 = 3/10

Also, P(BB/H) = 1/2 = P(C-3PO/H)

We can say that Han Solo is likely to hide them in aceta BB-8 and C-3PO

To begin,

(a). The question tell us to find the probability that the codes are with BB-8.

First of all, we find P(BB).

P(BB) = P(L)*P(BB/L) + P(H)*P(BB/H)

solving this we get

P(BB) = 0.6*7/10 + 0.4*1/2 = 0.62

Therefore, the probability that the codes are with BB-8 = 0.62

(b). The second question says;

Given that the codes are with C-3PO, what is the probability the codes were hidden by Han Solo?

This tell us to find P(H/C-3PO)

P(H/C-3PO) = P(C-3PO/H)*P(H) / P(C-3PO/H) + P(C-3PO/L)*P(L)

inputting the values gives us;

P(H/C-3PO) = 1/2 * 0.4 / ( 1/2 *0.4 + 3/10 *0.6) = 0.53

SO we have that the probability the codes were hidden by Han Solo = 0.53

cheers I hope this was helpful!!

Calculate the distance between the points L = (1, -3) and P = (8,– 7) in the coordinate plane.

mylen [45]

The exact distance between two points L=(1,-3) and P=(8,-7)is 8.062 units, is obtained by formula and graphical method.

Step-by-step explanation:

The given is,

Two points are L=(1,-3) and P=(8,-7)

Step:1

By graphical method,

First point L (1,-3)

The values of x=1 and y=-3 noted in the graph

Second point P(8, -7)

The values of x=8 and y=-7 noted in the graph

Now join the points L and P, in the graph,

Distance between two points are 8.1 units

( OR )

Step:2

By formula method,

Distance = $\sqrt{(x_{2}-x_{1}) ^{2}+ (y_{2}-y_{1} ) ^{2} }$

Where,

L (1,-3) are ( $x_{1}, y_{1}$ )

P (8,-7) are ( $x_{2}, y_{2}$ )

Substitute the values,

= $\sqrt{(8-1) ^{2}+ (-7+3 ) ^{2} }$

= $\sqrt{(7) ^{2}+ (-4 ) ^{2} }$

= $\sqrt{49+ 16 }$

= $\sqrt{65}$

Distance = 8.06225 units

Result:

The exact distance between two points L=(1,-3) and P=(8,-7)is 8.062 units, is obtained by formula and graphical method.
