What is the y-intercept of the line perpendicular to the line y = four thirdsx + 1 that includes the point (4, 1)?
avanturin [10]

Answer:

4

Step-by-step explanation:

We'll begin by calculating the slope of the equation. This is illustrated below:

y = 4/3x + 1

Comparing the above equation with:

y = mx + c

The slope (m) of line is 4/3.

Next, we shall determine the slope of the equation perpendicular to:

y = 4/3x + 1

This is illustrated below:

When two lines are perpendicular, their slope are related as:

m2 = – 1/m1

From the above, m1 = 4/3

m2 = –1 ÷ 4/3

m2 = –1 × 3/4

m2 = – 3/4

Next, we shall determine the equation passing through (4, 1). This is illustrated below:

y – y1 = m(x – x1)

y1 = 1

x1 = 4

m = – 3/4

y – y1 = m(x – x1)

y – 1 = –3/4 (x – 4)

y – 1 = –3/4x + 3

y = –3/4x + 3 + 1

y = –3/4x + 4

Comparing:

y = –3/4x + 4 with y = mx + c

The y-intercept, c is 4.

A USA Today/Gallup poll asked a group of unemployed and underemployed Americans if they have had major problems in their relatio
Tems11 [23]

Answer:

Null hypothesis: <em>H₀</em>: <em>p</em>₁ = <em>p</em>₂.

Alternate hypothesis: <em>H₀</em>: <em>p</em>₁ ≠ <em>p</em>₂.

Step-by-step explanation:

A statistical experiment is conducted to determine whether the proportions of unemployed and underemployed people who had relationship problems were different.

Let <em>p</em>₁ = the proportion of unemployed people who had relationship problems and <em>p</em>₂ = the proportion of underemployed people who had relationship problems.

A hypothesis test for difference between proportions, can be conducted to determine if there is any difference between the two population proportions.

Use a <em>z</em>-test for the test statistic.

The hypothesis test is:

<em>H₀</em>: There is no difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. <em>p</em>₁ = <em>p</em>₂.

<em>Hₐ</em>: There is a significant difference between the proportions of unemployed and underemployed people who had relationship problems, i.e. <em>p</em>₁ ≠ <em>p</em>₂.

Hello!
avanturin [10]

Answer:

  • 7.71 km²

Step-by-step explanation:

<u>Area of triangle:</u>

  • A = 1/2bh

We have the value of b but not h.

Added auxiliary segments which help to find the value of h.

<em>See attached for details</em>

  • sin 40° = h/4
  • h = 4 sin 40°
  • h = 2.57 km

<u>The area is:</u>

  • A = 1/2*6*2.57 = 7.71 km²
