Answer:

No

Step-by-step explanation:

We are given that,

The relation in the form of ordered pairs (age, height) is given by,

(11,62), (12,64), (13,65), (13,67) and (14,68).

'A function is a relation in which every element has a unique image'.

So, for the given relation to be a function, every element must have unique image.

But, For age 13, there are girls with 65 and 67 inches of height i.e. the ordered pairs (13,65) and (13,67) exists.

Thus, 13 does not have a unique image.

Hence, the given relation is not a function.

Replace * with a monomial in such a way, that the trinomial becomes a perfect square. *+12x+1

Answer: * = 36x^2

Note: Im guessing you're here for rsm struggles. That's how I found this question. I searched the web for the answer to this rsm problem, but I couldnt find it. I was happy to find this brainly link, but annoyed to find it was unanswered. I did the problem, and now i'll help future rsm strugglers out. Thanks for posting this question.

Step-by-step explanation:

Ok, so we know that trinomials like this are squares of binomials. this in mind, we know that it can also be written as (x+y)^2. (also brainly's exponents feature used to be better, if the exponents are confusing you, comment.) Using the (x+y)^2 equation, you know that by simplifying it, you get x^2+2xy+y^2. Basically we're looking for x^2. Using the middle term, 2xy, or 12x in this equation, we can find x. since we know the square root of 1 is 1, we know 12=2x. This is kinda confusing, but basically since the answer is 6, we know that the x-term is 6x. We square 6x and get 36x^2. guaranteed to work on the rsm student portal, i'm in rsm and i just answered this question.

Hope this helps! Also, im not usually too active on brainly unless im looking for HW answers, so if you understand this explanation and you see a confused comment, help out a friend and answer it. Happy holidays!

nlexa [21]

Answer:

Step-by-step explanation:

Given :

Scores     Number of students

 0                     1

 1                      2

 2                     5    

 3                     3

 4                     6

 5                     7

 6                     9

To Find: Mean

Solution:

Mean = \frac{\text{Sum of all scores}}{\text{number of students}}

Mean = \frac{0 \times 1+1\times 2+2\times 5+3\times 3+4\times 6+5\times 7+6\times 9}{1+2+5+3+6+7+9}

Mean = \frac{134}{33}

Mean = 4.06

Hence, The Mean of baseball score is 4.06 .
