Round 16.527 to the nearest tenths place.

1 answer:

4 0

16.53
if the next number is 5 or higher thats when you round it to the next number. so since the tenths place is , and the hundredths place is 7 (greater than 5) you would round two up to three.

The average weight of a chicken egg is 2.25 ounces with a standard deviation of 0.2 ounces. You take a random sample of a dozen

n200080 [17]

Answer:

$P(\bar X$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:

$X \sim N(\mu,\sigma)$

And let $\bar X$ represent the sample mean, the distribution for the sample mean is given by:

$\bar X \sim N(\mu,\frac{\sigma}{\sqrt{n}})$

On this case $\bar X \sim N(2.25,\frac{0.2}{\sqrt{12}})$

Solution to the problem

We want this probability:

$P(\bar X$

The best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

If we apply this formula to our probability we got this:

$P(\bar X$

Please help me if you can thank you.

Answer:

Its D

Step-by-step explanation:

If r is less than q, then it is on the left side because that is the lowest position avaliabe on the number line. If s is q+1, that means s is one more than q so s is bigger than q. If q is more than r and less than s, it is in the middle of those two. So, r is on the left most side, q is in the middle, and s is on the right side because it is the most.

Answer:

Step-by-step explanation:

-6+2n=3n-(6+5)

-6+2n=3n-11

-6+2n-3n=-11

-6-n=-11

n=-6-(-11)

n=-6+11
