Answer:
1.) It is biased
2.) No
3.) Yes
4.) No
Step-by-step explanation:
1.) It is biased as it is predisposition to one particular outcome over another.
2.) No, because biased in research leads to unrepresentative outcomes as the estimates is predisposed to the left or to the right of the true values.
3.) Yes. Since the selection of shift has an equal probability of being chosen.
4.) No. The probability that the sample accurately reflects the efficiency of the workers, the standard should be 95%.
Answer:
The given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
Step-by-step explanation:
Given expressions are x+3(7-x) and x+21-3x and also given that they are equivalent
To find for what property the given two expressions are equivalent :
x+3(7-x)=x+3(7)+3(-x)
=x+21-3x ( here we are using the distributive property a(x+y)=ax+ay )
Therefore the given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
Answer and Step-by-step explanation:
We are given:
A side length of 7
An angle of 30.
We will use trigonometric functions to solve for a.
We will use the sine trig function.
Multiply a by both sides, then divide by sin30 on both sides.
Now, use a calculator and do 7 divided by sin of 30.
We get <em><u>a</u></em> to be:
14
<u>a is equal to 14</u>
