Answer:

k = 9

Step-by-step explanation:

For this, we can factor the top expression to look like the bottom expression.

So, first we have to find the gcf of 18 and x^{2} and add up to 11x.

18x^{2}            11x

1 and 18       19   - No

2 and 9       11    - Yes

3 and 6       9    - No

So, the numbers are 2 and 9. The expression should now look like this:

x^{2} + 2x + 9x + 18

Now, undistribute the terms.

x(x + 2) + 9(x + 2)

(x+2)(x+9)

This matches up with the bottom expression.

The value of k is 9.

svlad2 [7]

ANSWER



x=10


and


y=20




EXPLANATION



Since corresponding angles are equal,


4x+y=60---(1)




Alternate angles are also equal, therefore,


8x+y=100---(2)



Equation (2) minus equation (1) gives,



\Rightarrow 4x=40




\Rightarrow x=10




We put x=10 in to equation (1)





4(10)+y=60



y=60-40




y=20

Solve the inequality for t.<br><br> 11 ≤ t + 4<br><br> Simplify your answer as much as possible.
Softa [21]

Answer:

t≥7

Step-by-step explanation:

11≤t+4

4 moves to the other side hence its sign changes

11-4≤t

7≤t

they change sides

t≥7

the sign was facing t so this does not change

Suppose that you are asked if there would be a strong or weak correlation between the number of people shopping in malls and the
solong [7]

There could be a strong correlation between the proximity of the holiday season and the number of people who buy in the shopping centers.

It is known that when there are vacations people tend to frequent shopping centers more often than when they are busy with work or school.

Therefore, the proximity in the holiday season is related to the increase in the number of people who buy in the shopping centers.

This means that there is a strong correlation between both variables, since when one increases the other also does. This type of correlation is called positive. When, on the contrary, the increase of one variable causes the decrease of another variable, it is said that there is a negative correlation.

There are several coefficients that measure the degree of correlation (strong or weak), adapted to the nature of the data. The best known is the 'r' coefficient of Pearson correlation

A correlation is strong when the change in a variable x produces a significant change in a variable 'y'. In this case, the correlation coefficient r approaches | 1 |.

When the correlation between two variables is weak, the change of one causes a very slight and difficult to perceive change in the other variable. In this case, the correlation coefficient approaches zero
