Answer:

Step-by-step explanation:

The best way to do this is to first remove the parenthesis by distributing the negative into them. Then we will group the like terms together, moving their respective signs with them, then we will simplify.  For the first one, after distributing the negative into the parenthesis (remember that a negative in front of a set of parenthesis containing a polynomial changes the signs in front of each term within the polynomial; negatives become positives and positives become negatives):

3x^2-6x+11-10x^2+4x-6 and then grouping like terms next to each other:

3x^2-10x^2-6x+4x+11-6 (this step is not completely necessary; I just encourage new learners to do it so as to not miss any of the like terms)

The above then simplifies to

-7x^2-2x+5

The next one, after distributing the negative into the parenthesis:

-3x^2-5x-3+10x^2+7x-2 and then grouping like terms next to each other (remember to move their signs with them!):

-3x^2+10x^2-5x+7x-3-2 which simplifies to

7x^2+2x-5

Now for the last one:

12x^2+6x-5-5x^2-8x+12 and

12x^2-5x^2+6x-8x-5+12 which simplifies to

7x^2-2x+7

A restaurant manager collected data on the number of customers in a party in the restaurant and the time elapsed until the party
Stella [2.4K]

Answer:

Option C The parties with a larger number of customers are associated with the longer times elapsed until the party left the restaurant.

Step-by-step explanation:

The correlation coefficient 0.78 shows that positive association between two variables number of customers and elapsed time until party left restaurant.

The positive association means that as the number of customers in a party increases the elapsed time also increase. So, we can say that the parties with a larger number of customers are associated with the longer times elapsed until the party left the restaurant.

If sarah is 24 years younger than her mother and if the sum of their age is 68 how old is sarah
UkoKoshka [18]
The sum of two numbers if just the numbers added together, so you would just need to do some simple algebra.

The ages added together are 68, and the opposite of addition is subtraction!

(total age) - (sarahs age) = (mothers age)
68 - 24 = 44

44 should be her mothers age!


(If you were trying to calculate the sum of their ages, you would just add them together, and 24 + 44 = 68)
