Answer:
0.0778, 0.1789,0.0250
Step-by-step explanation:
Given that μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5
(Right tailed test)
To find p value:
a) Z = 1.42: p = 0.077804
=0.0779
b) z = 0.92
p value = 0.1789
c)z= 1.96
p value = 0.0250
Answer:
S(-2,12)
y= -2(x+2)²+12
Location of coordinate axes:
y=0 → x= -2±√6 (-2-√6,0) (-2+√6,0)
x=0 → y=4 (0,4)
Answer:
<CBA = <CDA
Step-by-step explanation:
Using <CBA = <CDA and Base angle theorem, you can say that AB = AD.
Now you have <CBA = <CDA, AB = AD, and CB = CD. These prove SAS.
Answer:
15 inches
Step-by-step explanation:
12 inches = 1ft
