For what value of x is the area of the rectangle greater than the perimeter? The base of the perimeter is x+2
TiliK225 [7]
If we call the area A, then A=7(x+2)=7x+14
if we call the perimeter P, then P=7*2+2(x+2)=2x+18
A>P
7x+14>2x+18
subtracting 14 gives 7x>2x+4
subtracting 2x gives 5x>4
dividing by 5 gives x>\frac{4}{5}
or x>0.8

Which characteristic of a data set makes a linear regression model unreasonable?
LiRa [457]

Which characteristic of a data set makes a linear regression model unreasonable?

Answer: A correlation coefficient close to zero makes a linear regression model unreasonable.

If the correlation between the two variable is close to zero, we can not expect one variable explaining the variation in other variable. For a linear regression model to be reasonable, the most important check is to see whether the two variables are correlated. If there is correlation between the two variable, we can think of regression analysis and if there is no correlation between the two variable, it does not make sense to apply regression analysis.

Therefore, if the correlation coefficient is close to zero, the linear regression model would be unreasonable.

The difference between two integers is 32.The ratio of these integers is 1:3.Find these integers​
shutvik [7]

Answer:

16 and 48

Step-by-step explanation:

let the 2 integers be x and 3x ← ratio 1 : 3

Then

3x - x = 32 ← difference between the integers

2x = 32 ( divide both sides by  2 )

x =  16

and 3x = 3 ×  16 =  48

Since magnitude of difference is 32

We can also express the difference as

x - 3x = 32

- 2x = 32 ( divide both sides by - 2 )

x = - 16

and 3x = 3 × - 16 = - 48

The 2 integers are 16 and 48 or - 16 and - 48

Solve for x does anyone know how to do this?​
riadik2000 [5.3K]

Answer:

x = 9

Step-by-step explanation:

The sum of the 4 angles in a quadrilateral = 360°

Sum the given angles and equate to 360

90 + 109 + 9x - 5 + 85 = 360, that is

9x + 279 = 360 ( subtract 279 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9
