Answer:
Step-by-step explanation:
Given that evolution theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and wakingdash–even if they are not exposed to the usual pattern of sunlight.
Sample size n = 8
df = 8- 1=7
Since population std deviation is not known, and sample size is small we can use only t test
(two tailed test at 5% level of significance)

sd 3.142857143
se 1.111167799
Test statistic = Mean diff/se = 1.595
p = 0.1546
since p >0.05, accept null hypothesis.
There is no evidence to prove that the steady cycle is different from 24 hours.
Answer:
3
Step-by-step explanation:
Select an ordered pair: (2, 7)
Select another ordered pair: (6, 19)
slope = (difference in y)/(difference in x)
slope = (19 - 7)(6 - 2)
slope = 12/4
slope = 3
X=32 because when you have an even set of numbers, you have to take the two in the middle and find the mean of them:
24+x=28•2
24+x=56
x=32
Answer:
x =7 or x = -4
Step-by-step explanation:
|2x – 3| = 11
There are two solutions to an absolute value equation, one positive and one negative
2x-3 =11 or 2x-3 = -11
Add 3 to each side
2x-3+3 = 11 +3 2x-3+3 = -11+3
2x = 14 2x = -8
Divide each side by 2
2x/2 =14/2 2x/2 = -8/2
x =7 x = -4
Answer:
You have to measure the sides and make sure they are the same and you shape them to look like a square
