Answer:
15) f = 18
3f = 54
6f = 108
16) k = 69
Step-by-step explanation:
15)
3f + 6f + f = 180
10f= 180
f = 18
16)
42 + k + k = 180
42 + 2k = 180
2k = 138
k = 69
Answer:
interval = [17.3948 , 20.6052]
Step-by-step explanation:
given,
random sample (n) = 45
average product lifespan = 19 years
standard deviation = 4 years
confidence interval of 99 % = ?
we know,
t* = qt(1.99/2 + 44 ) = qt(0.995,44)
t* = 2.692
so,
interval
interval = [19 - 1.6052 , 19 + 1.6052]
interval = [17.3948 , 20.6052]
Line b is the answer, hope this helped
Answer:
Matt is correct
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
In this problem we can have two cases
case 1) The two equations are equal, in this case the system has infinite solutions
case 2) The two equations have the same slope but different y-intercept, in that case the system has no solution.
therefore
Matt is correct
