Answer:
It's all explained below :)
Step-by-step explanation:
So first we need to go to a graphing calculator! I usually use Desmos to do my stats stuff. You'll wanna head to their linear regression calculator (I can't add a link, but just google Desmos linear regresion and it'll pop up).
Put the points into the table. Lines of best fit have the equation y1 ~ bx1+a, so put that in the box right below the table, where you see another equation already written- just edit it. We see all the other numbers listed below that, so we know that b=-0.894 and a=13.599, so the line of best fit is -0.9x + 13.6 = y when you round those numbers.
The correlation coefficient is represented by the letter r. r is shown below as well, and is -0.964. Strong correlations are represented by a value close to the number 1, so this is strong, as it's very close. It is negative because of its sign. Correlation coefficients don't go over the number 1 or below -1, so be careful. I hope this was helpful! If you need any more clarification just let me know.
They travel to school by picking the amount of conductions associated with the classmates. They travel with their belongings and bring them with them as they transport to their location (school). Once they get to school than they must place their belongings. The population is associated with global and significance. They will then conduct and the math teachers wont be worried.

32+90+8y-6=180 solve that equation and that should be your answer
Answer:
1. x ≤ -8
2. y < -8
3. y < -11
4. n > 10
5. n ≤ -2
6. n ≤ 15
7. n ≤ -5
Step-by-step explanation:
Your goal is to get just the variable on one side of the inequality!
For example, take -2y - 4 > 18.
Add 4 to both sides. So... -2y - 4 + (4) > 18 + (4)
Now you get -2y > 22. Since y isn't by itself, let's divide both sides by -2.
So, (-2y / -2) > (22 / -2)
<u>Anytime you're dividing something by a negative, remember to FLIP THE SIGNS.</u> So instead of a greater than, it will now be a less than sign <.
Now you get, y < -11
If tan(x) = a/4, then
a is opposite <span>to the angle x and
4 </span><span>is adjacent to the angle x
</span>If cos(x) = 4/b, then
4 is adjacent to the angle x and
b is the hypotenuse
sin(x) = opposite/hypotenuse =
a/b
Answer is D.
