What is always true when comparing a negative and positive number

2 answers:

When you have two negative decimals, the one closer to zero is always greater. The farther a negative decimal is from zero, the smaller its value. A positive number is always greater than a negative number. This also holds true for decimals and fractions.

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical

sleet_krkn [62]

Answer: $c=4\sqrt{2}$

Step-by-step explanation:

For this exercise you need to apply the Pythagorean Theorem. This is:

$h^2=l^2+m^2$

Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.

In this case, you can identify that:

$h=c\\\\l=a=4\\\\m=b=4$

Knowing these values, you can substitute them into $h^2=l^2+m^2$ :

$c^2=4^2+4^2$

Now you must solve for "c":

$c=\sqrt{4^2+4^2}$

Evaluating, you get:

$c=\sqrt{16+16}\\\\c=\sqrt{32}$

To simplify the result:

- Descompose 32 into its prime factors:

$32=2*2*2*2*2=2^5$

- By the Product of powers property, you know that:

$2^5=2^4*2$

- Make the substitution:

$c=\sqrt{2^4*2}$

- Finally, knowing that $\sqrt[n]{a^n}=a$ , you get:

$c=2^2\sqrt{2}\\\\c=4\sqrt{2}$

san4es73 [151]

Answer: Using Chi-square.

Step-by-step explanation: To check if the provided data show any differences in preference for the two detergents (i.e., two variables), a Chi-square can be deployed, as it is used to test the goodness of fit, and test if two variables are related.

If the value obtained is less than 0.05, it means that there is statistical difference between the preference for the two detergents.

However, if the obtained value is higher than 0.05, it translates that there is no statistical difference between the preference for the two detergents.
