Answer:
Step-by-step explanation:
Since population std deviation is not known, we use t critical value for testing of hypothesis.
a) 90% conf level when n =28
df = 27, t critical = 1.706
b) 95% 28
df =27 and t critical = 2.052
c) 90% and 15
df =14 and t critical = 1.761
d) 95% and n =15
df =14: t critical = 2.145
Answer:
x = -4
Step-by-step explanation:
Give Me brainllest
The answer would be theorem Side angle side (aka SAS)
Domain- {-2, 1, 0, 1, 2}
Range- {-2, 0, 2}
My domain is right but I don’t think my range is. I did learn this 4 years ago though so
First answer is 27
Multiply -3 with -1
Then multiply it to the 3rd power.
2nd answer is 1 / 1296
First add the expoinents
-12 +8 = -4
Then you would need to do the equation
6^-4 x 6^0
And this would equal 1/1296
