Answer:

<em>H₀</em>: The voting preference of men and women are not different.

<em>Hₐ</em>: The voting preference of men and women are not different.

Step-by-step explanation:

A hypothesis test for two proportions can be used to determine whether the preference of men differ from women in case of voting.

A Chi-square test contingency table can be used to perform the test.

The hypothesis can be defined as:

<em>H₀</em>: The voting preference of men and women are not different.

<em>Hₐ</em>: The voting preference of men and women are not different.

The test statistic is:

\chi^{2}=\frac{Row\ total\times Column\ total}{N}

Decision rule:

If the <em>p</em>-value of the Chi-square test statistic is less than the significance level <em>α</em> = 0.05 then the null hypothesis will be rejected. And if the <em>p</em>-value is more than the significance level then the null hypothesis will not be rejected.

Can anyone get this answer
Doss [256]
This problem is asking you to apply the *Pythagorean Theorem*, given the information you’ve been given.

In case you’ve forgotten, the Pythagorean Theorem states that, in any given right triangle, the sum of the squares of the lengths of its legs is equal to the square of the length of its hypotenuse (the side opposite its right angle). If we call the lengths of the legs a and b, and the length of the hypotenuse c, this can be expressed in notation as a^2+b^2=c^2 (it doesn’t matter in this case which leg you pick for a and which you pick for b). Here, if we choose the left leg as a and the bottom leg as b, we’re given that a^2 (the area of a square with sides of length a) is 25 sq. in, and b is 3.5 in. Plugging those values into the equation, we have:

25 + (3.5)^2 = c^2

From here, you don’t even need to solve for c, you just need to find the value of c^2 (since you’re trying to find the area of a square with side lengths c). Just solve the left side of the equation, and you’ll have your answer in square inches.

Find the Inverse of the Function<br><br> y= 10x^2 - 4
shusha [124]
Hello.

1. Switch y and x.
x = 10y^2 - 4
2. Isolate y.
x + 4 = 10y^2
(x + 4)/(10) = y^2
y = sqrt[(x + 4)/(10)]
3. Replace y with f^-1(x)
f^-1(x) = sqrt[(x + 4)/(10)]

Good luck to you!
