2/10 (or 1/5 ) Times 2/10 (or 1/5)
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.
Answer: 62.1 , angle Y , The triangles are not similar
Step-by-step explanation:
Answer:
We need to sample at least 37 weeks of data.
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

We want 98% confidence that the sample mean is within $500 of the population mean, and the population standard deviation is known to be $1300
This is at least n weeks, in which n is found when 
So






Rounding up
We need to sample at least 37 weeks of data.
A number and its absolute value are not equal when the number is less than zero. Since subtracting 2 makes the number less than zero, we know ...
... the number is a non-negative number less than 2. (0 ≤ n < 2)
