This sample size it too small. The larger the sample size, the more likely the data will be true to what the question is asking. A larger sample size brings more precision to the question that is being asked.
Most likely 1.06 but it could be 1.06666667. good luck
Answer:

Step-by-step explanation:
We have been given the expression:

We will use the property:

Here, 
So, we will get from the identity:

Hence, you are not right because you removed square rrot in final result rest is right.
X= 75
y= 105
this is because x is equal to the angle with 75, y us 105 because 180-75=105. 180 is found because the angle of a line is 180
Answer:
x=-5, x=-9
Step-by-step explanation:
Use zero product property to set each term to 0: x+5=0, x+9=0.
x=-5, x=-9
