I am a rectangular, and my area is 80 squares inches. My width is 2 inches shorter than my length . What is muy perimeter ?

1 answer:

8 0

The area is 80. Since the width of the rectangle is 2 inches shorter, the width has to be 8 and the length is 10. To find the perimeter, you add all the sides of the shape. In this case, we would add 8, 8, 10, 10.

8 + 8 + 10 +10 = 36

So the answer is 36 inches.

Solve for z. 20 − (z + 7) = 0.9

zhannawk [14.2K]

Answer:

x = 12.1

Step-by-step explanation:

20 − (z + 7) = 0.9

Distribute the minus sign

20 -x -7 = .9

Combine like terms

13 -x = .9

Subtract 13 from each side

-x = -12.1

x = 12.1

Which r–value represents the strongest negative correlation? –0.7 –0.22 0.38 0.9

inn [45]

Answer:

Option A is correct.

The value of r = -0.7 represents the strongest negative correlation.

Step-by-step explanation:

A correlation is a value that describes a relationship between two things or variables.

Strongest Negative Correlation says that closer a negative correlation to -1, the stronger the relationship between the two variables.

From the options, we have only two negative values i.e, r= -0.7 and r= -0.22.

We have to find the strongest negative correlation r-value.

By the definition, you can see that -0.7 is very closer to -1 ,

therefore, the value of r = -0.7 represents the strongest negative correlation.
