Answer:
1. Equation: y = -1.17491x + 81.791 (you may need to round!)
2. Correlation coefficient: -0.8566
3. Strong negative correlation because the correlation coefficient is close to -1
4. Sketch the scatterplot using north latitude as the x value and Jan mean temp as the y value on the graph
Step-by-step explanation:
Step 1: Go to desmos graphing calculator
Step 2: Insert a table
Step 3: Insert values into the table (shown in image) using the north latitude as the x value and jan mean temp as y value
Step 4: Go to line 2, and type "[tex]y_1 = mx_1 + b[/tex]" except replace "=" with ~ as shown in the image. Put the 1s as subscripts
Step 5: Scroll out. Desmos would've graphed the line of best fit and plotted the points. Under statistics, you can see that r is the correlation coefficient
Step 6: The correlation coefficient r will be between -1 and 1. If it is closer to -1 or 1, it is a strong correlation. If it is closer to 0, it is a weak correlation. For example. -0.6 is closer to -1 than it is to 0, so it is a strong negative correlation. You can see that r here is -0.8566, which is strong negative.
Step 7: Lastly, you need to make the equation. It will be in the form y = mx + b. If you look under "parameters", there will be a value for m and b. Plug that in to the equation. Check to see if you need to round.
Step 8: To graph the scatterplots, you can use the graph and the points that desmos plotted as a reference. Good luck!

how many solutions? y=9x+11 y=-9X+11
Answers
9514 1404 393
Answer:
1 solution: (0, 11)
Step-by-step explanation:
Each equation is in slope-intercept form. It is easy to see that the slopes are different and the y-intercepts are the same.
The fact that the slopes are different means there is one solution.
The fact that the y-intercepts are the same means that solution is the y-intercept.

x = -3, y = -2
O x = 2, y = 3
O x = 2, y = 2
O x = 3, y = 2 soemone tell me which one-
Answers
Answer:
It's the last one where x=3 and y=2
Explanation:
Replace x and y with 3 and 2. It then becomes
-4(3) + 8(2) = 4
Solve. -4 × 3 is -12 since a positive times a negative equals a negative. 8 × 2 is 16. Bring down the 4.
-12 + 16 = 4
When solving something like this and you don't know what to do or how to solve it, you can subtract the smaller number from the larger number and then whether the sum is a negative or positive depends on the largest number. So here, 16 is the largest, so the sum will be positive. And 16-12 is 4, so the final answer is positive 4. You can also look at a number line and start from -12 and then add 16 and see which number you end at after adding 16.

Two trains, Train A and Train B, weigh a total of 379 tons. Train A is heavier than Train B. The difference of their weights is 255 tons. What is the weight of each train?
Answers
Answer: A = 317
B = 61
Step-by-step explanation:
The following equation can be gotten from the question given. This will be:
A + B = 379 ........ i
A - B = 255 ........ ii
From equation i, make A the subject of the formula
A = 379 - B ...... iii
Put the value of A in iii into equation ii
A - B = 255
(379 - B) - B = 255
379 - B - B = 255
379 - 2B = 255
2B = 379-255
2B = 124
B = 124/2
B = 62 tons
Since A + B = 379
A + 62 = 379
A = 379 - 62
A = 317 tons

The distance between two cities on a map is 17 cenimeters.The scale on the map relates 5 cenimeters on the map as 30 miles on the road.What is the actual distance in miles,between the two cities
Answers
Answer:
105 miles on map
Step-by-step explanation:
Given data
Distance on map= 17cm
scale= 5 centimeters on the map as 30 miles on the road
hence
if 5cm rep 30 miles
17cm rep x
cross multiply
5*x= 17*30
x= 510/5
x= 105 miles
Hence the distance is 105 miles on map
A boat traveled 150 miles downstream (with the current) and back (against the current). The trip downstream took 10 hours. The trip back took 30 hours. What is the speed of the boat (b) in still water? What is the speed of the current (c)?
Answers
Answer:
b= 10 miles/hr and c= 5 miles/hr
Step-by-step explanation:
Let it's downstream and upstream speed be d and u respectively
also speed of the boat be b and speed of stream be c.
as per question d = 150/10= 15 miles/hr
and, u= 150/30= 5 miles/hr
also we know d= b+c = 15.....i and u = b-c= 5....ii
solving i and ii we get b= 10 miles/hr and c= 5 miles/hr
