Part B: Describe how you can make the line of the best fit. write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate the slope and y-intercept.
(please explain how you got the slope and y-intercept with the numbers from the question if you would like brainliest)
Answer: We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are
Slope0.3848 ± 0.03956
Y-intercept0.6053 ± 0.6370
X-intercept-1.573
1/Slope2.598
Step-by-step explanation: Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.

solve and find the missing angles.
Answer:
60°
Step-by-step explanation:
Since this is an equilateral triangle all the angles and sides are the same.
180÷3=60°
All the angLes will be 60°, because in a triangle ball angles must add up to 180°.
Hope this answers your question.

Name a set of vertical angles in the image below:
A. 2 and 3
B. 1 & 3
C. 1 & 4
D. 4 & 3
Explanation:
Vertical angles form when we have an X shape like this. They are opposite one another and always congruent. Angles 2 and 4 is the other set of vertical angles.
Answer:
B. 1 & 3
Step-by-step explanation:
The vertical angles are pairs of opposite angles made by 2 intersecting lines. Here, 1 and 3 are the same length, and are on opposite sides.

Answer:
b = 42° and c = 180-42 = 138°
Answer:
b) 42°
c) 138°
Step-by-step explanation:
Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.
Hope this helps! Have a wonderful rest of your day!

find surface area of the prism pls!!!!! explain too. I really need help!!!
Answer: 104 square inches
Step-by-step explanation:
The surface area of a prism is the sum of the surface are of all of it's faces.
We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.
Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)
Simplify with multiplication to get this: SA = 24 + 20 + 60
Simplify with addition to get this: SA = 104
Add the unit label and you get 104 square inches.

Answer:
He should have multiplied 15 tsp by 1 tbsp/3tsp.
Step-by-step explanation:
The tsp labels cancel each other out when one is the numerator and one is the denominator.
15tsp x 1 tbsp/3tsp = 15/3 = 5 tbsp

When a spaceship full of scientists landed on Planet Q, they found that 17/40 of the 160 aliens had 3 eyes. How many aliens had 3 eyes?
Answer:
68 aliens
Step-by-step explanation:
Take the fraction of aliens that had 3 eyes and multiply by the number of aliens
17 / 40 * 160 =
17 * 160/40
17 *4
68

[Help Please!] Find the value of x.
Answer:
x = 52
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles of a triangle
x+72 = 34+90
x +72 =124
Subtract 72 from each side
x = 124-72
x =52
Answer:
x = 52 degrees
Step-by-step explanation:
Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as
180 degrees - (x + 72 degrees), or 108 - x degrees.
The three interior angles of the triangle must add up to 180 degrees. Hence
108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:
108 - x + 34 = 90
This yields x = 52 degrees.
Which angles are supplementary to each other ? Select all that apply
Answer:
6 and 4
Step-by-step explanation:
Answer:
Choice 3: ∠5 and ∠6
Step-by-step explanation:
Supplementary means straight, and these two angles form a straight line when added together (angle measurements add up to 180)
