Answer:
w = -1/2
Step-by-step explanation:
Eliminate parentheses, collect terms:
7w +14 = -12w +6 +3w . . . eliminate parentheses
7w +14 = -9w +6 . . . . . . . . collect terms
16w +14 = 6 . . . . . . . . . . . . add 9w
16w = -8 . . . . . . . . . . . . . . . subtract 14
w = -1/2 . . . . . . . divide by 16, reduce the fraction

<em>Check</em>
7(-1/2 +2) = -6(2(-1/2) -1) +3(-1/2)
7(3/2) = -6(-2) -3/2
21/2 = 12 -3/2 . . . . . true, answer checks OK
Answer:
A) 60 miles/hour
Step-by-step explanation:
Answer:
probability = 0.9286
Step-by-step explanation:
given data
mean = $8.30
standard deviation = $4.70
waits parties over a weekend of work = 60
solution
when we earn at least $550 in 60 parties
so average per party will be x = 
average x = 9.1667
so now we get here z value that is
...............1
put here value and we get
z = 
z = 0.184404
so
P(x>9.1667) = P(z>0.184404)
use standard normal table
probability = 1 - 0.0714 = 0.9286
a3=9
assuming the pattern is constant, a3 is right in the middle of a1 and a5 so the answer would be right in the middle of 6 and 12. the average of 6 and 12 is 9, so a3=9.
hope this helps!
The y-intercept represents the initial girth of the tree. Assuming that the X-axis represents time in this scenario (as it usually does) the y-axis, therefore, represents the girth of the tree. The y-intercept is located where X = 0. So if no time has passed then this must be the first measurement of the girth of the tree.
