Discussion:
99/9081 = => as 9081 = 9 * 1009 = 3 * 3 * 1009
99/ ( 3 * 3 * 1009) =
(99/(3*3)) * (1/1009) =
(99/9) * (1/1009) =
11/ 1009 =
.0109 approximately
Thank you,

Answer:3y-3y=0
Step-by-step explanation: They are giving you a value for X that is 3y. You put that value in place of x. So, if x=12 and they want you to substitute for x-3y=0, you would have 12-3y=0....but the value of x in your question is 3y....so you replace the x in the equation with it's value...which is given to you as 3y....or in my example, 12.
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]
Answer:
