The answer is D one third of AB.
My best guess is “t=1” I’m not sure of it
Answer:
1a) 90 = 2y + 2(2x) 1b) 45 - 2x = y
Step-by-step explanation:
1a) 90 = 2y + 2(2x)
1b) 90 = 2y + 2(2x) Use the equation from above and multiply
90 = 2y + 4x
-4x - 4x Subtract 4x from both sides
90 - 4x = 2y Divide both sides by 2
45 - 2x = y
95% confidence interval is given by
x - 2D , and x+ 2D
For 99% confidence interval is
x - 3D , and x + 3D
x = 100000
D = 2000
Then calculate
100000 - 3•2000= 94000
and
100000 + 3•2000= 106000
Now find √D = 44.72
Then interval is
100000 - 44.72 ,. And. 100000 + 44.72
99,956 lower limit and. 100472 upper limit
Then we see that theres only one interval ,
that is between thes 2 limits
ANSWER Is OPTION C) ) ($99.996.46, $100,003.55)
X = -1/10
2=10x+3
10x+3=2
10x = 2 - 3
10x = -1
x = - 1/10
