What is the domain and the range of these functions?? quick please!!!!!!!!!!

Sever21 [200]

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. A rational function is a function of the form f(x)=p(x)q(x) , where p(x) and q(x) are polynomials and q(x)≠0 .

g A test was conducted to determine if there is a difference between Canadian and American average heart rates. A group of 36 Ca

melisa1 [442]

Answer:

The test statistic | t | =4.45

Step-by-step explanation:

Step(i):-

Given that the first sample size n₁ = 36

Given that the second sample size n₂ = 34

Mean of the first sample x₁⁻ = 68.5

Mean of the second sample x₂⁻ = 70

Step(ii):-

Test statistic

$t = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} } } )}$

$t = \frac{68.5-70}{\sqrt{2(\frac{1}{36}+\frac{1}{34} ) } }$

$t = \frac{-1.5}{0.337} = -4.45$

The test statistic | t | = |-4.45| =4.45

Find the GCF (Greatest Common Factor) of 64 and 144

valkas [14]

Answer: 16

Step-by-step explanation:

if we were to list all the factors of 64 and 144

64= 1,2,4,8,8,16,32,64

144= 1,2,3,4,6,8,9,12,12,16,18,24,36,48,72,144

therefore the GCF of 64 and 144 is 16
