Gelneren [198K]

Answer:

The kind of sampling the researcher is using is Convenience sampling method.

The sum of and 7x2 is 10x2
Tems11 [23]

<u><em>Answer:</em></u>

The missing term is 3x²

<u><em>Explanation:</em></u>

Addition and subtraction can only take place between like terms.

<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms

<u>Now, consider the given terms:</u>

First term is 7x² has the variable x with degree 2

The resulting term is 10x² has the variable x with degree 2

This means that the missing term is ax²

We need to get the value of "a"

<u>This is done as follows:</u>

ax² + 7x² = 10x²

x²(a+7) = 10x²

a+7 = 10

a = 10-7

a = 3

Therefore, the missing term is 3x²

Hope this helps :)

SVEN [57.7K]

Answer:

The estimated amount to be paid by ronaldo is $5.9895

Step-by-step explanation:

total amount spent on arcade = $18.15

percentage bill to be paid by ronaldo= 33%

Amount to be paid by ronaldo is   =    \frac{33 \times 18.15}{100}

                                                        =   \frac{598.95}{100}

                                                        = 5.9895

So the estimated amount to be paid by ronaldo is $5.9895
