an economic research commission claimed that among the 500 stores there are 308 dealing with european companies, 266 dealing with asian companies 103 dealing with both sides regularly and 59 not dealing with either side. i) what is the probability that the stores deal with european or asian companies? ii) what is the probability that the stores do not deal with european companies? iii) what is the probability that the stores only deal with asian companies? iv) what is the probability that stores do not deal with only one type of company

Answers

Answer 1

Step-by-step explanation:

Let S be the set of all the stores in the sample, A be the set of stores dealing with Asian companies and E but the set of stores dealing with European companies

i. The set of stores that deal with European or Asian companies is A ∪ E. The inclusion-exclusion principle states that |A ∪ E| = |A| + |E| - |A ∩ E| = 266 + 308 - 103 = 471. So P(A ∪ E) = 471/500 = 0.942

ii. E' = S - E. |S-E| = 500 - 308 = 192. So P(E') = 192/500 = 0.384

iii. |A - E| = |A| - |A ∩ E| = 266 - 103 = 163. So P(A - E) = 163/500 = 0.326

iv. Stores that do not deal with only one type of company, must deal with both Asian and European companies. We are given that |A ∩ E| = 103. So P(A ∩ E) = 103/500 = 0.206

iki sayının oranı 5/8 dir bu iki sayının farkı 24 olduğuna göre toplamı kaçtır​

Answers

Answer:

x = -40 and y = -64

Step-by-step explanation:

The ratio of the two numbers is 5/8, since the difference of these two numbers is 24, what is the sum

Let two numbers be x and y.

ATQ,

x-y = 24 ..(1)

and

[tex]\dfrac{x}{y}=\dfrac{5}{8}[/tex]

or

8x-5y =0 ...(2)

Multiply equation (1) by 8.

8x-8y = 192 ...(3)

Subtract equation (3) from (2).

8x-5y -(8x-8y) = 0-192

-5y+8y = -192

3y = -192

y = -64

Put the value of y in equation (1).

x-(-64) = 24

x+64 = 24

x = -64+24

x = -40

So, the values of x and y are -40 and -64 respectively.

Find the mean,median,mode, and range:5,2,5,2

Answers

Answer:

Mean = 3.5

Median = 3.5

Mode = 5, 2

Step-by-step explanation:

Hope that helps!

Mean: To find the mean, simply add the numbers together and divide by the amount of numbers in the set:

Mean: (5 + 2 + 5 + 2)/4

= (14)/4

= 3.5

Mean = 3.5

Median: To find the median, simply order from least to greatest, and find the middle number in the set. That is your median. In the case of an even amount of numbers in the set, find the mean with the two median numbers (as in this case):

Median: (2 + 5)/2

= 7/2

= 3.5

Median: 3.5

Mode: The Mode is the number that shows up the most frequently. As both given numbers show up the same amount of times (twice), there is no mode.

Mode: None.

Range: The Range is found by subtracting the greatest number with the least number:

5 - 2 = 3

Range: 3
