stepan [7]

Answer:

About 1 gallon. (32/30)

Step-by-step explanation:

First get a LCM (least common multiple) for 3, 5, and 2.

Now we have 30. Make 30 the denominator for all.

10/30

15/30

7/30

Then add them all up to get 32/30.

About 1 gallon.

A scatter plot is made with the data shown below: Number of Waiters at a Restaurant 5 6 7 8 9 10 11 12 13 Customer Service Ratin

bonufazy [111]

Answer:

No association .

Step-by-step explanation:

Given : A scatter plot is made with the data shown below: Number of Waiters at a Restaurant 5 6 7 8 9 10 11 12 13 Customer Service Rating 4 2 10 7 1 2 8 9 5

To find : What type of association will the scatter plot for these data represent between the number of waiters at a restaurant and its customer service rating.

Solution : We have given :

Number of Waiters at a Restaurant = 5 6 7 8 9 10 11 12 13

Customer Service Rating = 4 2 10 7 1 2 8 9 5 .

Here x coordinates are 5 6 7 8 9 10 11 12 13

y coordinates are 4 2 10 7 1 2 8 9 5 .

(5,4) (6,2) (7,10 )(8,7) (9,1)(10,2)(11, 8) (12, 9) (13, 5)

We can see there is no pattern between x and y coordinates .

Therefore, No association .

Find LCM of: x2 - 9, 3x3 + 81

VikaD [51]

Answer:

$\boxed{\pink{\sf (x + 3) \ is\ the \ LCM . }}$

Step-by-step explanation:

Given two expressions ,

$\qquad (1)\: x^2 - 9 \\\\ \qquad (2)\:3x^3 + 81$

And , we need to find the LCM , that is lowest common factor . So , let's factorise them seperately .

Factorising x² - 9 :- 

$= x^2 - 9 \\\\= x^2 - 3^2 \\\\ \red{= (x+3)(x-3)} \qquad\bf [Using \ a^2-b^2 = (a+b)(a-b) ]$

Factorising 3x³ + 81 

$= 3x^3 + 81\\\\= 3(x^3+27) \\\\= 3( x^3+27) \\\\ = 3(x^3+3^3) \\\\ \red{= 3 [ (x+3)(x^2+9-3x) ] } \qquad \bf{[ Using \ a^3+b^3=(a+b)(a^2+b^2-ab) ] }$

Hence we can see that (x+3) is common factor in both expressions.

Hence the LCM is ( x+3 ) .
