ARAT TIETE (Simplify): V125 - V45+ V5​

Mathematics
1 answer:
Nataly [62]2 years ago
6 0

Answer:

3\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{125}

= \sqrt{25(5)}

= \sqrt{25} × \sqrt{5} = 5\sqrt{5}

\sqrt{45}

= \sqrt{9(5)}

= \sqrt{9} × \sqrt{5} = 3\sqrt{5}

Then

\sqrt{125} - \sqrt{45} + \sqrt{5}

= 5\sqrt{5} - 3\sqrt{5} + \sqrt{5} ← collect like terms

= 3\sqrt{5}

What equation represents a circle with its centre at the origin, and a radius measuring 12 units
Nastasia [14]

Answer:

The equation is x² + y² = 144.

Step-by-step explanation:

This works the same way as before.

You know that at the origin, it equals (0, 0). So, we have no need to insert values for h and k. Therefore, it will just be x² + y² = r².

R is your radius, and this is given as 12 units. So, r = 12. Therefore, r² = 144.

Your final equation is x² + y² = 144.

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to sta
Dafna11 [192]

Answer:  <em>r</em> represents a significant linear correlation.

Step-by-step explanation:

GIven : Linear correlation coefficient: r = 0.543

Sample size: n= 25

Significance levle: \alpha=0.05

Degree of freedom : n-2 = 25-2=23

Now, we check <em>r</em> critical value table for value with df = 23 and \alpha=0.05.

Critical value = ±0.396  [From <em>r</em> critical value table]

Since r = 0.543 > 0.396, that means there is significant linear correlation.

Hence,  <em>r</em> represents a significant linear correlation.
