Answer:
Hence the degrees of freedom are associated with the critical value is 25.
Step-by-step explanation:
Using two independent samples, two population means are
compared to determine if a difference exists, the population standard deviation is equal.
sample size 1 = 
= 15 and sample size 2 = 
= 12
since, population standard deviations are equal, required degrees of freedom
Answer:
176
Step-by-step explanation:
11x11=121
12x11=132
9=20-11
16-9=7
11x16=176
Hope this helped you :D
And pls give me brainlist if you can
Answer:
MAYBE: 14?
Step-by-step explanation:
i just read it in the pic above and worked it out.
Answer:
5) D
6) C
7) B
8) D
9) 109°
10) 83°
Step-by-step explanation:
5) In y=mx+b the slope is m. In perpendicular it'll be opposite, so the answer is D.
6) With the above knowledge about slope, the slope will be the same so it'll be C.
7) They are in the same position by different lines and will be corresponding aka B
8) These are adjacent angles because they are next to each other aka D
9) 180 - 71 = 109
10) They are correspodning so 83°
(slightly rushing so I hope this helped, have a nice day!)
