parallel lines have the same slope

y = 4x-5 the slope is 4

slope intercept form

y= mx+b

the slope is 4 and the y intercept is 3

y = 4x +3

The slope intercept form is:

y = mx + b

"m" being the slope, "b" being the y-intercept (the y value when x = 0)

For lines to be parallel, the slope has to be the same.

The slope of the given equation is 4, so your parallel line's slope is also 4.

y = 4x + b

The y-intercept is at (0,3), so your y-intercept (y value when x = 0) is 3

y = 4x + 3

A recent poll asked people whether they supported passing a constitutional amendment to ban burning of the national flag using a

Answer:

Step-by-step explanation:

Hello!

You are asked to test the difference of the population means of the opinion of men and women over a constitutional amendment to ban burning the national flag.

Population 1 (women)

Sample n₁= 400

X[bar]₁= 80.6

Population 2 (men)

n₂= 586

X[bar]₂= 77.6

σ₁= σ₂ = σ =3.5

To test whether there is a difference between the opinion of people about the amendment regarding their gender the hypothesis is:

H₀: μ₁ - μ₂ = 0

H₁: μ₁ - μ₂ ≠ 0

α: 0.05

The statistic to use is a pooled Z:

Z= (X[bar]₁ - X[bar]₂) - (μ₁ - μ₂) ~N (0;1)

σ*√(1/n₁ + 1/n₂)

The critical region for this hypothesis is two tailed:

$Z_{\alpha /2} = Z_{0.025} = -1.96$

$Z_{1-\alpha /2} = Z_{0.975} = 1.96$

Z= (X[bar]₁ - X[bar]₂) - (μ₁ - μ₂) = (80.6-77.6) - 0 = 13.215

σ*√(1/n₁ + 1/n₂) 3.5√(1/400 + 1/586)

Since the calculated Z-value is greater than the right critical value -81.96) the decision is to reject the null hypothesis. There is significant evidence to conclude that there is no difference between the population means of the opinion about the constitutional amendment to ban the burning of the national flag of women and men.

I hope it helps!
