2/5 (x-4)=2x answer is x= -1
Answer:
An introduction of sets and its definition in mathematics. The collection of well-defined distinct objects is known as a set. ... The word well-defined refers to a specific property which makes it easy to identify whether the given object belongs to the set or not.
Answer:
<em>The first step is to determine the average
</em>

<em>The exercise says it’s a normal distribution: (n=8)</em>

<em>According to the exercise, the mean is equal to 0,5 then the value of t of the distribution can be obtained
</em>
<em />

<em>The variable t has 7 grade to liberty, we calculate the p-value as:
</em>

This value is very high, therefore the hypothesis is not rejected
Answer:
−438°, -78°, 642°
Step-by-step explanation:
Given angle:
282°
To find the co-terminal angles of the given angle.
Solution:
Co-terminal angles are all those angles having same initial sides as well as terminal sides.
To find the positive co-terminal of an angle between 360°-720° we will add the angle to 360°
So, we have: 
To find the negative co-terminal of an angle between 0° to -360° we add it to -360°
So, we have: 
To find the negative co-terminal of an angle between -360° to -720° we add it to -720°
So, we have: 
Thus, the co-terminal angles for 282° are:
−438°, -78°, 642°
