Answer: 8/11

Step-by-step explanation:

This is because there are a total of 22 bulbs. 16 of those bulbs work, giving us the fraction: 16/22. If you simplify 16/22 by dividing the numerator and denominator by 2, you get 8/11.

Please Help Me with this permutations and combinations math problem​
Paraphin [41]

Step-by-step explanation:

you do know what a combination stands for ?

n over r = n! / (r! × (n-r)!)

and you know what "!" (factorial) means ?

it means it is the product of

n × (n-1) × (n-2) × (n-3) × ... × 3 × 2 × 1

so, now we only need to calculate the whole thing.

10 over 4 = 10! / (4! × (10-4)!) = 10! / (4! × 6!) =

= 10×9×8×7 / 4×3×2 = 5×3×2×7 = 210

10 over 6 = 10! (6! × (10-6)!) = 10! / (6! × 4!) =

= the same as 10 over 4 = 210

8 over 7 = 8! / (7! × (8-7)!) = 8! / (7! × 1!) = 8

6 over 2 = 6! / (2! × (6-2)!) = 6! /(2! × 4!) =

= 6×5 / 2 = 15

6 over 4 = the same as 6 over 2 = 15

9 over 6 = 9! / (6! × (9-6)!) = 9! / (6! × 3!) =

= 9×8×7 / 3×2 = 3×4×7 = 84

so, we have then

210×210 - 8×15 + 15×84 = 44100 - 120 + 1260 =

= 45240

The table shows the age of some participants in a quiz competition and the number of questions they could answer correctly:
GalinKa [24]

Option first "0; it represents no correlation between x and y" is correct there is no relation between x and y.

<h3>What is correlation?</h3>

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}

 

We have:

Age (years) (x)                                                     15  21   17  22  16  19  18

Number of questions  they could answer(y)    17  17   17  17    17  17  17

As we can see all y values are the same.

n∑y² = 7(2023) = 14161

(∑y)² = 119² = 14161

If we put the value of the above data the value will become undefined.

Thus, option first "0; it represents no correlation between x and y" is correct there is no relation between x and y.
