I was taught that you don't add numbers & letters together hope this helps
y = f(x) + c is the graph y = f(x) shifted upward c units.
y = f(x) - c is the graph of y = f(x) shifted downward c units.
y = f(x - c) is the graph of y = f(x) shifted to the right c units.
y = f(x + c ) is the graph of y = f(x) shifted to the left c units.
Answer:
C.
Step-by-step explanation:
Here , the given expression is :
ASSOCIATIVE PROPERTY OF ADDITION
For any terms a, b and c
a + (b + c) = (a +b) + c, Here the order of the addition is NOT important.
Now, simplifying the given expression with the above property:
So, the correct option of the all , Option C is the correct option.
Answer:
538 books should be tested.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
How many books should be tested to estimate the average force required to break the binding to within 0.08 lb with 99% confidence?
n books should be tested.
n is found when
We have that
Rounding up
538 books should be tested.
