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.

Express 16 1/4in simplest radical form

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

${16}^{ \frac{1}{4} } \: can \: also \: be \: written \: as \: ( {{2}^{4})}^{ \frac{1}{4} }$

because ${2}^{4} = 16$

So,

${( {2}^{4} )}^{ \frac{1}{4} } = {(2)}^{4 \times \frac{1}{4} } = 2$

I need help please

Range is y so we set -5x = whatever number you pick from the range values listed, so

-5x = -5 making x=1

-5x = 0 making x=0

-5x = 10 making x=-2

-5x = 15 making x=-3

The domain is {1,0,-2,-3}

Wale was twice as old as Ajay 10 years back. How old is Ajay today if Wale will be 40 years old 10. years hence?

vagabundo [1.1K]

Using a system of equations, it is found that Ajay is 25 years old today.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Variable x: Wale's age.

Variable y: Ajay's age.

Wale was twice as old as Ajay 10 years back, hence:

$x - 10 = 2(y - 10)$

$x - 10 = 2y - 20$

$x = 2y - 10$

Wale will be 40 years old in 10 years, hence:

$x + 10 = 40$

$x = 40$

Then, Ajay's present age is found as follows.

$2y = x + 10$

$2y = 40 + 10$

$y = \frac{50}{2}$

$y = 25$
