Answer:
X = 2, 4, 6, 7, 9
Y = 29, 33, 37, 39, 43
Step-by-step explanation:
Given a best fit line of :
y = 2x + 25
Take points X as :
X = 2, 4, 6, 7, 9
X = 2
y = 2(2) + 25 = 4 + 25 = 29
X = 4
y = 2(4) + 25 = 8 + 25 = 33
X = 6
y = 2(6) + 25 = 12 + 25 = 37
X = 7
y = 2(7) + 25 = 14 + 25 = 39
X = 9
y = 2(9) + 25 = 18 + 25 = 43
Answer: 115 degrees
Step-by-step explanation: By the property of alternate interior angles, they are congruent.
Answer:
0.16 ft
Step-by-step explanation:
v = 4/3 πr³
v = 4/3 × 3.142 × 1/3 × 1/3 × 1/3
v = 0.16 ft
First you distribute what’s outside the parentheses (the -4)
-4•4= -4y
-4•-2= 8
New equation: -4y+8=12
Now you solve like a normal equation
12-8 is 4
New equation: -4y=4
Now divide
