Answer:
-3 and it is a negative whole number
-3/1 is a negative integer
Step-by-step explanation:
-3/1 divide -3 by one which is always the same number you are dividing by and you'll get -3
Answer:
28
Step-by-step explanation:
Degrees of freedom is defined as the number of independent values or quantities which can be assigned to a statistical distribution.
#In a two sample study, the t-statistic degrees of freedom is calculated as
#Where
denotes the sample size of the
sample.
![DoF=(15+15)-2=28](https://tex.z-dn.net/?f=DoF%3D%2815%2B15%29-2%3D28)
The t-statistic degrees of freedom is thus 28
We see that the angle measures are the same, but the side lengths aren't, so these shapes qualify as similar. Since it's similar, they are also the same shape.

Answer:
4. w = 31
5. x = 50
Step-by-step explanation:
To find the values of variable w and x in the given triangles above, recall that the sum of angles in a triangle = 180°.
Therefore,
==>w° + w° + (4w - 6)° = 180°
Solve for w
w + w + 4w - 6 = 180
6w - 6 = 180
Add 6 from both sides
6w = 180 + 6
6w = 186
Divide both sides by 6
w = 186/6
w = 31
==>Also, x° + x° + (x + 30)° = 180
x + x + x + 30 = 180
3x + 30 = 180
Subtract 30 from both sides
3x = 180 - 30
3x = 150
Divide both sides by 3
x = 150/3
x = 50
