This would be a Quintic Trinomial; it has a degree of 5 and 3 terms.
Answer:
36 objects
Step-by-step explanation:
You want the value of x when t=9, so you're solving ...
9 = 0.007x^2 +0.003x
9 = 0.007(x^2 + 3/7x)
From here, we observe that an approximation is probably sufficient.
9/0.007 = x(x +3/7) . . . . . the expression on the right is nearly x^2
x ≈ 3/√.007 ≈ 35.9 ≈ 36
We can check:
.007(36)(36 3/7) = 9.18
.007(35)(35 3/7) = 8.68
To keep the computer busy for 9 seconds, it needs to sort 36 objects.
It's the first choice. If you multiply the first equation by 3, your y term is a +12, and if you multiply the second equation by 4, your y term is a -12. When you add them the y terms cancel each other out.
For this case we must find a fraction such that its result is given by a decimal of the form:
, that is, a repeated decimal.

Answer:
The 90% confidence interval is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 64
The sample mean is 
The standard deviation is 
Given that the confidence interval is 90% then the level of significance is mathematically evaluated as


Next we obtain the critical value of
from the normal distribution table , the value is

Generally the margin of error is mathematically represented as

=> 
=> 
The 90% confidence interval is mathematically represented as

=> 
=>
