Answer:

y = $\frac{3}{4\\}$ x + 2

Step-by-step explanation:

To find the slope:

Find two spots where the line intersects and exact point. (-8,-4)(-4,-1)

Either count up & over or do y1-y2 / x1-x2 (-4+1)/(-8+4) -3/-4 3/4

The intercept is where it crosses the y-axis, in this case 2

Write the equation like this y = mx + b where m=slope & b=intercept

y = 3/4x + 2

Do men’s voting preferences differ significantly from women’s voting preferences?"" Use a level of significance of α = 0.05. Whi

baherus [9]

Answer:

H₀: The voting preference of men and women are not different.

Hₐ: 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:

H₀: The voting preference of men and women are not different.

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

Rewrite the expression with the given base. 16^x with a base of 2.

olga55 [171]

Keeping in mind that 16 = 2*2*2*2, thus 16 = 2⁴

$\bf 16^x\implies (2^4)^x\implies 2^{4\cdot x}\implies 2^{4x}$

a(x+b)=4x+10 in the equation above a and b are constants. if the equation has infinitely many solutions for X, what is the value

xeze [42]

Answer:

$b= \frac{5}{2}$

Step-by-step explanation:

Given

$a(x+b)=4x+10\\ax+b= 4x+10\\$

Now we know that system has infinite solution for x

$\frac{a_1}{a_2}=\frac{b_1}{b_2}$

in above equation.

$a_1=a, a_2=4, b_1=ab,b_2=10\\$

∴ $\frac{a}{4}=\frac{ab}{10}\\\therefore b=\frac{10\times a}{4\times a}=\frac{5}{2}$
