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.

The answer is 2.

Since the number below the first shape is 1, you would have to multiply by 2 to get to 2 (which is the number under the second shape).

Bradley is returning home from a place that is 2 kilometers away. The function y = 2,000 − 90x represents Bradley's distance fro

GenaCL600 [577]

Answer:

The function is a linear function.
The function changes at a constant rate.

Step-by-step explanation:

The degree of x is 1, so the function is a linear function.

The coefficient of x is -90, a constant rate of change that is negative, so the function is <em>decreasing</em>.

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2

dangina [55]

Answer:

irrational

Step-by-step explanation:

A = s^2

s^2 = 24,200

$s = \sqrt{24200}$

$s = \sqrt{242 \times 100}$

$s = \sqrt{100 \times 121 \times 2}$

$s = 10 \times 11\sqrt{2}$

$s = 110\sqrt{2}$

P = 4s

$P = 4 \times 100 \sqrt{2}$

$P = 440 \sqrt{2}$

The perimeter is irrational.

Factor the expression completely. (If the expression is not factorable using integers, enter PRIME.)

Archy [21]

First you have to put like terms together:
bf+af+be+ae
Now you factor the first two terms and then the two last terms:
f(b+a)+e(b+a)
Now you factor even further. By putting what is in parentheses by what is outside the parentheses:
(b+a)(f+e)
What you got is correct as mine is too. I hope this formula helps for future problems:
ax+bx+ac+bc=x(a+b)+c(a+b)
=(a+b)(x+c)
