Answer:
Step-by-step explanation:
We are to find critical values for the test given
a) df =16: Alpha = 0.01 and right tailed
Critical value= 2.583
b) df = 23-1 = 22: alpha = 0.1 and left tailed
critical= -1.717
c)df=31-1 =30: alpha =0.1: two tailed
t =1.697
Critical values can be obtained from critical t tables.
Left tailed will have negative sign and right tailed positive
Answer:
? = 70°
Step-by-step explanation:
180 - 120 = 60° (120° and 60° are supplementary angles)
180 - 50 - 60 = 70° (all triangle interior angles total 180°)
Answer:
x+5+\frac{1}{x-2}
X + 5 + 1/( x - 2)
Step-by-step explanation:
I would recomend using Symbolab to help you understand math like this in an easy step-by-step manner. It will take a while to explain so you can see how to solve these problems through that!
<em>I believe that the answer should be A. </em>
4 could be considered a common factor
0.8w + 3.6 =
4(0.2w + 0.9)
or you could call 0.4 the common factor
=0.4(2w+9)
= (2/5)(2w+9), if you want to eliminate decimals. 0.4=4/10=2/5
