Answer:
a) H0: μEuro - μChinese = 0 vs. Ha: μEuro - μChinese > 0
b) Newborn European infants weigh more, on average, than newborn Chinese infants.
Step-by-step explanation:
<em>Null hypothesis</em> would be: infants of European descent has the same weight at birth as Chinese infants. μEuro = μChinese or μEuro - μChinese = 0
And the <em>alternative hypothesis</em> would be: infants of European descent heavier at birth than infants of Chinese descent. μEuro > μChinese or μEuro - μChinese > 0.
Because in particular infants of the European infants are considered heavier. If not, the alternative hypothesis would be μEuro ≠ μChinese
or μEuro - μChinese ≠ 0.
test a p-value of 0.001 is significant at α = .05, therefore null hypothesis is rejected in favor of alternative hypothesis Ha: μEuro - μChinese > 0, or Newborn European infants weigh more, on average, than newborn Chinese infants.
Bearing in mind that complex roots, do not come all by their lonesome, the zeros of "-i" or "0-i" and "-7+i" aren't here all by themselves, they came with their sister, the conjugate
so, that is 0-i also comes with 0+i
and -7+i also comes with -7-i
so, the zeros, or solutions or roots, are
so, their product, is the 5th degree polynomial
Answer:
you do 8/2 which is 4, so that is ur radius
you do 3.14*4*4=50.24
there is ur answer!
Step-by-step explanation:
The value of (f/g)(-1) is 0, value of (g . f) (2) is -3√3, the value of (g - f)(-1) is √15, and the value of (g + f) (2) is √3 - 3
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have two functions:
f(x) = 1 - x²
g(x) = √(11 - 4x)
f(-1) = 0
g(-1) = √15
f(2) = -3
g(2) = √3
(f/g)(-1) = f(-1)/g(-1) = 0/√15 = 0
(g . f) (2) = g(2)f(2) = (√3)(-3) = -3√3
(g - f)(-1) = g(-1) - f(-1) = √15 - 0 = √15
(g + f) (2) = g(2) + f(2) = √3 + (-3) = √3 - 3
Thus, the value of (f/g)(-1) is 0, value of (g . f) (2) is -3√3, the value of (g - f)(-1) is √15, and the value of (g + f) (2) is √3 - 3
