From left to right:
Negative, positive, none, nonlinear
1 is negative bc it has a negative slope
2 is positive because it has a positive slope
3 has no correlation because there is no pattern
4 is no linear because it’s not in a line, essentially. (This would be a parabola)

Answer:
200 miles
Step-by-step explanation:
40 x 5 = 200
If you have a graphing calculator, you could use it to solve this question.
If you have a TI-84, go to <em>MATH</em> then <em>PROB</em> then <em>3: nPr</em>
From there, all you have to do is type in 7 and 3 in their correct spots to get 210 as your answer.
So to find the medium you need to put the numbers in order from least to greatest so for the first one it would be like this 103, 111, 113, 114, 122, 129,
<span>130, 138, 140, 141, 145 and then you find the number that is in the middle of the set so for sample one it would be 129</span>
Answer:
a = 2, b = - 3, c = - 8
Step-by-step explanation:
Expand f(x) = a(x + b)² + c and compare coefficients of like terms, that is
a(x + b)² + c ← expand (x + b)² using FOIL
= a(x² + 2bx + b²) + c ← distribute parenthesis by a
= ax² + 2abx + ab² + c
Compare like terms with f(x) = 2x² - 12x + 10
Compare coefficients x² term
a = 2
Compare coefficients of x- term
2ab = - 12, substitute a = 2
2(2)b = - 12
4b = - 12 ( divide both sides by 4 )
b = - 3
Compare constant term
ab² + c = 10 , substitute a = 2, b = - 3
2(- 3)² + c = 10
18 + c = 10 ( subtract 18 from both sides )
c = - 8
Then a = 2, b = - 3, c = - 8
