Answer:

C. (6x+5y) (6x+5)

Step-by-step explanation:

30xy +36x^2 + 30x +25y

I will factor by grouping

36x^2 + 30xy + 30x+25y

Factor out a 6x from the first group and a 5 from the second group

6x(6x+5y) +5(6x+5y)

Now factor out a (6x+5y)

(6x+5y) (6x+5)

Mid point formula

(x1 + x2) , (y1+y2)
--------- --------
2 2
Thus for x it would be (6+(-2)) /2 or 4/2 or 2.
For y (-4 + 4) / 2 or 0 / 2 or 0.
Mid point is (2,0)

Does the graph of y = sin x + cos x have even symmetry, odd symmetry, or neither? Use a graphing calculator.

Neporo4naja [7]

Hello!

Odd functions are functions that are symmetric with respect to the origin.
Even functions are functions that are symmetric with with respect to the y-axis.

Therefore, the graph of y = sin(x) + cos(x) has no symmetry (neither).

IrinaK [193]

Answer:

A researcher is interested in comparing the usage of bank debit cards by consumers in rural (r) and urban (u) areas. Each year for the past five years, she has surveyed 500 individuals (one‑half urban, one‑half rural) randomly selected from across the United States. She is specifically interested in any differences that may exist between the two groups with regard to usage. The results of the current study indicate that people in urban areas use bank debit cards 12 times per month on average, while those in rural areas use bank cards 10 times per month on average. Which of the following is the null hypothesis that the researcher should use in comparing the usage rates?

Option C is the correct answer.

Step-by-step explanation:

The null hypothesis is the hypothesis of no difference. Therefore, the appropriate null hypothesis will be:

There is no difference in the average monthly usage of debit cards between urban and rural people.

Therefore, option C is the correct answer.

it takes 30 kids 6 hours to build a man sized Sand Castle. how many kids were there if the same game took only two-and-a-half ho

Pachacha [2.7K]

Answer:

There were 72 kids there.

Step-by-step explanation:

This question can be solved using proportions, by a rule of three.

The number of kids and time are inversely proportional, that is, if we increase the number of kids to build the castle, the time it takes will decrease. This means that to solve the rule of three, instead of applying cross multiplication, we apply line multiplication.

We have that:

30 kids - 6 hours

x kids - 2.5 hours.

Applying line multiplication

$2.5x = 30*6$

$x = \frac{180}{2.5}$

$x = 72$

There were 72 kids there.
