The two dot plots below compare the forearm lengths of two groups of schoolchildren:

Angelina_Jolie [31]

Answer:

Group A, because seven children have a forearm length longer than 10 inches

Step-by-step explanation:

Create the dot plots based on the given information (please see attached images).

Group A = blue dots

Group B = red dots

From inspection of the attached dot plots, we can see that Group A appears to have the longer average forearm length. This is because 7 children have a forearm length of longer than 10 inches.

To calculate the average forearm length, sum all data values and divide by the total number of data values.

$\textsf{Average of Group A}=\dfrac{ 3 \times 10 + 4 \times 11 + 3 \times 12}{10}=11$

$\textsf{Average of Group B}=\dfrac{ 3 \times 9 + 5\times 10+ 2\times 11}{10}=9.9$

Thus proving that Group A has the longer average former length.

Factorize a² +3ab - 5ab - 15b².

olga nikolaevna [1]

Answer:

$a^2+3\,a\,b-5\,a\,b-15\,b^2=(a-5\,b)\,(a+3\,b)$

Step-by-step explanation:

Work via factoring by groups:

!) re arrange the terms as follows:

$a^2-5ab+3ab-15b^2$

then extract the common factor for the first two terms (a), and separately the common factors for the last two terms (3 b):

$a^2-5ab+3ab-15b^2\\a\,(a-5\,b)+3\,b\,(a-5\,b)$

Now notice that the binomial factor (a-5 b) is in both expressions, so extract it:

$a\,(a-5\,b)+3\,b\,(a-5\,b)\\(a-5\,b)\,(a+3\,b)$

which is the final factorization.

What is the domain of the function in this table

never [62]

Option A:

{3, 4, 5, 6}

Solution:

In the given table X column have 3, 4, 5, 6 and Y column have 4, 4, 2, 5.

The domain is the set of all values for which the function is defined.

The domain of the function is set of all X values.

Option A: {3, 4, 5, 6}

Set of all X values {3, 4, 5, 6}.

It is correct.

Option B: (3, 4), (4, 4), (5, 2), (6, 5)

Here, the given values are ordered pairs of domain and co-domain.

It is not correct.

Option C: (3, 4)

Here, (3, 4) is a ordered pair of domain and co-domain.

It is not correct.

Option D: {2, 4, 5}

Here, {2, 4, 5} are values of co-domain.

It is not correct.

Hence {3, 4, 5, 6} is the domain of the function.
