Answer:
104÷409= 0.2543≈ 0.25
Then, convert to a percent to get 25%
Answer:
A= 47 1/2
Step-by-step explanation:
A bar graph is a chart that uses bars to show comparisons of different types of data. The bars can either be horizontal or vertical. They are always straight if I’m not mistaken
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)

mean 25
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.
It will be secx = 2
or, cosx = 1/2
or x = Π/3 , 5Π/3
