Two supplementary angles are in the ratio 3 1 : 5 find both angles​
Zielflug [23.3K]

The two angles are 155 degrees and 25 degrees

<h3><u>Solution:</u></h3>

Given that two supplementary angles are in ratio 31 : 5

Let the first angle be 31a

Let the second angle be 5a

Two Angles are Supplementary when they add up to 180 degrees.

Therefore,

first angle + second angle = 180 degrees

31a + 5a = 180\\\\36a = 180\\\\a = \frac{180}{36}\\\\a = 5

<em><u>Therefore the angles are:</u></em>

first angle = 31a = 31(5) = 155 degrees

second angle = 5a = 5(5) = 25 degrees

Thus the two angles are 155 degrees and 25 degrees

When testing a new​ treatment, what is the difference between statistical significance and practical​ significance? Can a treatm
Arada [10]

Answer:

Statistical significance relates to whether an effect exists.

Practical significance refers to the magnitude of the effect.

And you can have statistical significance but not practical.

Step-by-step explanation:

Let's analize it with an example.

Suppose that your new treatment involves hair recovery.

You divide the population of the test in two different groups.

And you apply the treatment to only one of them.

You can see that the treatment works and there is a 3% improvment.

You have statistical significance. The treatment worked.

Now, if the test was expensive, the 3% improvement might not be practical.

PLEASE HELP!!! WILL MARK AS BRAINLISTS!!!
Serjik [45]

The limit is x---->4-

The negative show that x approaches from the left

Now

As x approaches 4 from the left ... Means This number should be less than 4 (<4) but really close to 4.

Let's pick a Number

Say 3.99

Substitute this... You have

3.99/3.99-4

3.99/-0.01

If we choose x to be 3.999

we will have

3.999/-0.001

Notice the pattern... As x approaches 4 from the left... This limit will approach NEGATIVE INFINITY

Why?

As you approach 4 from the left... 3.9,3.99,3.999... You notice that the denominator becomes negative and EXTREMELY SMALL... and when you divide by an extremely small Number..... You'll get a relatively HUGE VALUE(You can try this... Use a calc... Divide any number of choice by a very small number... say.. 0.0000001.... You'll get a huge result

In our case... The denominator is negative... So it Will Approach a very Huge Negative Number

Hence

Answer.. X WILL APPROACH NEGATIVE INFINITY.

Vertical asymptotes are the zeroes of the denominator of a function

The denom. is x-4

Equate to zero to get the asymptote

x-4=0

x=4

Hence... There will be a vertical asymptote at x=4.

Have a great day!
