Answer:
Step-by-step explanation:
Hehe
3
This experiment has four groups. Each of these groups have six observations
Total number of observations = 4 x 6 = 24
Treatment degrees of freedom can be gotten by using this formula
Df1 = K - 1
= 4-1
= 3
Therefore for this question, the treatment degrees of freedom is given as 3 and the correct answer option is b.
12
Factors of 30: 1,2,3,5,(6),10,15,30
Factors of 42: 1,2,3,(6),7,14,21,42
30 divided by 6, 42 divided by 6
(5) + (7)= 12
Greater than.
f(-4) = -12
To calculate f(-4), we need to substitute x in our equation above with -4:
Note that 2*(-4) = -8
Answer: f(-4) = -12
<em>76 degrees</em>
The corresponding angles help you solve this.
The vertical angle of x (meaning the one practically in front of it) is 76 degrees, since x is vertical to 76, the degree will be the same.
