A person can drive 200 miles in 4 hours.What is the constant of proportionality?
Eddi Din [679]
To get the constant of proportionality (unit rate) you must find the miles driven in 1 hour. To get this you simply divide 200 by 4...
200÷4=50
So, the constant of proportionality is 50 mph.

What is the measure of one interior angle of a polygon that has 50 sides
pashok25 [27]

Answer: 172.8°

Step-by-step explanation:

For a regular polynomial of N sides, the sum of all interior angles must be equal to:

Sum = (N - 2)*180°.

In this case we have N = 50

Then:

Sum = (50 - 2)*180° = 48*180°

Now, if all the 50 interior angles have the same measure, then the measure of each one will be equal to the quotient between the sum and the number of sides, this is:

Sum/50 = (48/50)*180° = 172.8°

Then the interior angles of a regular polygon of 50 sides is 172.8°

A researcher conducts a hypothesis test using a sample of n = 40 from an unknown population. What is the df value for the t stat
aliya0001 [1]

Answer:

Correct option: b 39.

Step-by-step explanation:

A one-sample (or one mean) t-test is applied to test whether the population-parameter is significantly different from some hypothetical value.

The degrees of freedom of the <em>t</em>-test is:

df = n - 1

It is provided that the sample size is, <em>n</em> = 40.

Compute the degrees of freedom as follows:

df = n - 1

   = 40 - 1

   = 39

Thus, the correct option is b.

Identify this problem plssss
JulsSmile [24]

Answer:

The answer is cot(x)

Step-by-step explanation:

<h3>Greetings !</h3>

\tan(x)  \csc {}^{2} (x)  -  \tan(x)

Rewrite using trig identity

-  \tan(x)  +  \csc {}^{2} (x) \tan(x)

use the Pythagorean idea

\csc {}^{2} (x)  = 1 +  \cot {}^{2} (x)

-  \tan(x)  + (1 +  \cot {}^{2} (x)) \tan(x)

simplify

\cot {}^{2} (x)   \tan(x)

use basic trigonometric identity

\tan(x    )  =  \frac{1}{ \cot(x) }

simplify

\cot {}^{2} (x)  \frac{1}{ \cot(x) }

gives you

\cot(x)

Hope it helps!
