Answer:
AC = 22
Step-by-step explanation:
Given that B is the midpoint of AC , then AB = BC , that is
2x + 1 = 5x - 14 ( subtract 2x from both sides )
1 = 3x - 14 ( add 14 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
Thus
AC = AB + BC = 2x + 1 + 5x - 14 = 7x - 13 = 7(5) - 13 = 35 - 13 = 22

Answer:
16 I think.
Step-by-step explanation:
if Marcus is 8 . Kimi is older. you do 8 times 2 . which is 16 .
Tan=z/10 and cos=10/y from cos we know the hypotenuse is y. from tan we know the opposite side is z
So sinx=z/y
Answer:
1)Reject H_o if t> 2.998
2) t = 2.8594
3) No, conclusion about positive association in population is not reasonable
Step-by-step explanation:
To Test
we know that Test statics is
1) Reject H_o if
n = 9,
Reject H_o if t> 2.998
2)
n = 9 r = 0.734
so we have t = 2.8594
3) t = 2.8594
therefore , hence we accept hypothesis or H_o
No, conclusion about positive association in population is not reasonable
