Suppose you are spinning pennies to test whether you get biased results. When you reject the null hypothesis when it is actually

true, that is often called the first kind of error. The second kind of error is when the null is false and you fail to reject. Report the first kind of error and the second kind of errorThe null hypothesis is that the penny is ........(not biased/biased). The first kind of error is saying the penny is ...,,(biased/not biased) when in fact the penny is .....(biased/not biased). The second kind of error is saying the pennyIs .....(not biased/biased) when in fact the penny is .....(biased/not biased).

_____ uses established rules to draw conclusions, whereas in _____, such rules are not established, and we may not know the cons
aliina [53]

Answer:

Reasoning, Decision making

Step-by-step explanation:

The reasoning is the process of mental. In the process, reasoning needs a reason for establishing the facts. This is a cognitive process. All people engage in reasoning due to their ability to introspection. The reasoning is different in every field in every aspect.  

The cognitive process plays a role in both reasoning and decision making. These both are the sub-field creative thinking. Many factors create a barrier in decision making such as incomplete information, emotional and physical resources.  

Thus when we may not know the consequences we used both reasoning and decision making.

Using the distance formula , find the distance from the center of your habitat to the point (x, y). Write this equation. Your an
alexdok [17]

Answer:

See explanation

Step-by-step explanation:

The distance formula is given by:

d =  \sqrt{ {(x_2-x_1)}^{2} +  {(y_2-y_1)}^{2}  }

We want to find the distance between (a,b) and (x,y).

The center of the habitat is missing in the question.

Assuming the center is (a,b) where a and b are real numbers, then we can use the distance formula to obtain:

d = \sqrt{(x - a)^{2} +  {(y - b)}^{2}  }

For instance if the center of your habitat us (2,-1), then

d = \sqrt{(x - 2)^{2} +  {(y  + 1)}^{2}  }

If 900 is shared in the ratio 8:10,find each shared
kirill [66]

Answer:

400 and 500

Step-by-step explanation:

the ratios are 8:10

total ratio = 8+10 = 18

share for the ratio is 8 = 8/18×900

= 0.444444444×900= 400

therefore, share for the ratio of 8= 400

share for the ratio of 10= 10/18×900

= 0.555555555×900=500

therefore, share for the ratio of 10= 500

How do we know what sign goes outside of the bracket when factoring binomials?
Xelga [282]
I'm assuming you're asking about negative or positive signs here. When I factor binomials, it depends on what would make factoring simpler for me. And how you're factoring the binomial too.

More often than not, it's going to be positive. For example, 4x^2 - 2x = 0. That would factor out to be 2x(2x-1) = 0. The sign outside is going to be positive because it's simpler to solve that way. Here, x is equal to 0 and equal to 1/2. Taking out a negative in this case would complicate the solving process.
