Answer:
AD = 104
Step-by-step explanation:
Since is the perpendicular bisector of AD, then
DB = AB, that is
9x - 2 = 7x + 10 ( subtract 7x from both sides )
2x - 2 = 10 ( add 2 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Thus
AD = 7x + 10 + 9x - 2 = 16x + 8 ← substitute x = 6
AD = 16(6) + 8 = 96 + 8 = 104
Answer:
x=-4
Step-by-step explanation:
4x-(x+2)+6=2(3x+8)
4x-x-2+6=6x+16
3x+4=6x+16
4=6x-3x+16
4=3x+16
3x=4-16
3x=-12
x=-12/3
x=-4
Answer:
(a)P(x>85.55)=0.02275
(b)
Step-by-step explanation:
We are given that
Average sales for an online textbook distributor per customer per purchase
,
$67.63
Standard deviation of the amount spent on textbooks,
$8.96
(a) We have to find probability for a randomly selected customer spent more than $85.55 per purchase.

=
=
=
P(x>85.55)=0.02275
(b)We have to find probability for a randomly selected customer spent less than $76.59 per purchase

Answer:
1000 meters below sea level
Step-by-step explanation:
Since the submarine dives at a depth of 4 times 200 meters, then it dives 800 meters.
Sso the submarine now is at 200 meters + 800 meters =1000 meters below sea level.
