The first one is x can equal 10 and y can equal 0
4^2 and 2^4
Btw ^number is the small number
Answer:
Step-by-step explanation:
Given that random sample of 25 values is drawn from a mound-shaped and symmetrical distribution. The sample mean is 10 and the sample standard deviation is 2.
95 % CI for mean 9.1744 to 10.8256
Since p >0.05 accept null hypothesis.
a) Yes because std dev sigma not known. df = 24
b)
H0: x bar = 9.5
Ha: x bar not equals 9.5
c) t-statistic 1.250
d) P = 0.2234
e) We fail to reject null hypothesis
f) There is no statistical evidence at 5% level to fail to reject H0.
Since the pentagon is regular, the sides are all of equal length. This tells you
... 5x-27 = 2x-6
... 3x = 21 . . . . . . . add 27-2x
... x = 7
The length of a side can be found by subtituting this value into either expression.
... 2·7-6 = 8 . . . . inches
62.4 minutes is the answer
