(x) = 3x + 5? domain and range
2 answers:
For this case we must find the domain and range of the following function:
By definition, the domain is given by all the values for which the function is defined. In this case, the given function is defined for all real numbers. That is to say:
Domain: (-∞,∞)
For its part, the range is the set of values that correspond to the domain. The values that the "y" variable takes. For this function, the range is given by all real numbers.
Range: (-∞,∞)
ANswer:
Domain: (-∞,∞)
Range: (-∞,∞)

Answer:
Part 1 , not significant
Part II, significant
Step-by-step explanation:
Given that a heterozygous white-fruited squash plant is crossed with a yellow-fruited plant, yielding 200 seeds. of these seeds, 110 produce white-fruited plants while only 90 produce yellow-fruited plants
(Two tailed chi square test)
We assume H0 to be true and find out expected
If H0 is true expected would be 100 white and 100 yellow
Chi square =
df = 1
p value = 0.152799
Since p value > 0.05 at 5% level we accept that the colours are equally likely
2)
Here observed are 1100 and 900
Expected 1000 & 1000
df = 1
Chi square =
p value <0.0001
These results are here statistically significant.
