The correct answer is the choice that you have selected, the third choice.
When, we are looking at the residuals for a regression line, we always want to see the points balance like in the third choice. This means that the equation that we found is right in the middle of the points.
Answer:
77cm, 780mm, 7.6m, 0.075km
this is the best answer
Answer:
Distance: 435.9 ft
Step-by-step explanation:
This is a right triangle shown in the picture.
To solve for
, we can use trigonometry.
The 35° angle's opposite side is 250 ft and the hypotenuse of the triangle is
(what we are seeking to find).
The ratio that relates opposite and hypotenuse is sine.
<em>We know that,</em>

<em>Thus we can write:</em>

<em>Cross multiplying and solving for
gives us:</em>

Second answer choice is right: 435.9 ft
Answer:the sailboats are 358 feet apart.
Step-by-step explanation:
The diagram of the triangle representing the situation is shown in the attached photo.
B represents the position of the lighthouse.
D represents the position of the first sailboat.
C represents the position of the second sailboat.
x represents the distance between the two sailboats
We would apply trigonometric ratio
Tan # = opposite/adjacent
For triangle ABD,
Tan 12 = 370/AD
AD = 370/Tan 12 = 370/0.2126 = 1740.357 feet
For triangle ABC,
Tan 10 = 370/AC
AD = 370/Tan 10 = 370/0.1763 = 2098.695 feet
x = AC - AD = 2098.695 - 1740.357 = 358 feet
