Answer:
-122
Step-by-step explanation:
The common difference is
-5-(-2)
-3
So
a+(n-1)d
-2+(41-1)-3
-2+(-120)
-122
Answer: I (5 + 2/3) oz - xI ≤ 2/5 oz.
Step-by-step explanation:
If we have a mean M, and a measurement error e, then the absolute value inequality that represents the possible values of x, the variable, is:
IM - xI ≤ e
This means that x can be, at maximum, at a "distance" e from M.
In this case, we know that the mean weight is (5 + 2/3) oz, and the error is +- 2/5 oz, then the absolute value inequality that represents this situation is:
I (5 + 2/3) oz - xI ≤ 2/5 oz.
Answer:
t = 8/5
Step-by-step explanation:
I'm assuming the equation given is the velocity of the particle
Derive the equation
Set it equal to 0 & solve for t
Answer:
r is always between 0 and 1
Step-by-step explanation:
The untrue statement is ...
r is always between 0 and 1
One way you can tell is that it is inconsistent with the true statement |r| ≤ 1.

<em>Comment on correlation coefficient</em>
The correlation coefficient (r) is the ratio of the covariance of x and y to the product of the standard deviations of x and y. This formula is symmetrical in x and y, so it doesn't matter which data set you call x and which one you call y. Similarly, the units cancel, so r is a unitless number, and the units of x and y don't matter, either.
