Answer:
y-intercept = 3
Step-by-step explanation:
The given equation is :
6x-5y=-15
We can rewrite it ib slope-intercept form as follows :
Dividing both sides by 5
.....(1)
The general equation of slope-intercept form is:
y = mx +c ....(2)
On comparing equation (1) and (2) we get :
m = 6/5
c = 3
Hence, the y intercept of the graph of the equation is 3.
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.
