Answer:

It mean that the observed progeny is similar than the expected progeny. There is no a relationship between the categorical variables.

Step-by-step explanation:

The Chi-squared test is used to test the relationship between categorical variables. A categorical variable is a non-numerical variable. The null hypothesis of the Chi-squared test is that categorical variables are independent; it means that the frequencies are not dependent on the variable. It is important to know that the Chi-squared test does not measure causality, it only measures the relationship. To reject the null hypothesis, you usually need a probability lower than 0.05, but in this case, the probability was way higher than 0.05, it was between 0.5 and 0.9.

What is the length of CO?
posledela

Answer:

Pythagorean theorem, eh?

Step-by-step explanation:

The way to do this is use the radius-tangent angle theorem thing...

It states that, a radius that intersects a point of tangency(I think that's what it's called) is perpendicular to the tangent. Thus, CW is perpendicular to OW!

Thus, it forms a right triangle, where we can use Pythagorean Theorem!

If you don't know what it is, check the internet! It's pretty simple.

CW^2+OW^2=OC^2\\144+81=OC^2\\225=OC^2\\OC=15

So, there you go! Hope this helps!

NOTE: This answer was recently deleted for violating community guidelines, so I just re-uploaded it!(and edited it) So if you do need more help, do some research!
