If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Your answer is A.

UseU={1,2,3,4,5,6,7,8,9,10},A={1,3,4},B={4,7,8,9},and C={2,6,10}to find the given set AUB

salantis [7]

Answer:

A ∪ B = { 1,3,4,7,8,9}

Step-by-step explanation:

U = {1,2,3,4,5,6,7,8,9,10}

A={1,3,4} B={4,7,8,9} and C={2,6,10}

UNION OF SETS:

Union of two sets is defined as the set which has all the elements from both the sets.

Also, REPETITION OF THE ELEMENTS in NOT allowed in union of sets.

Now, here:

A={1,3,4} B={4,7,8,9}

So, A ∪ B = { 1,3,4,7,8,9} ( element 4 is written only ONCE here)

A company receives shipments of a component used in the manufacture of a component for a high-end acoustic speaker system. When

Tanya [424]

Answer:

$ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434$

Step-by-step explanation:

For this case we have a sample size of n = 250 units and in this sample they found that 24 units failed one or more of the tests.

We are interested in the proportion of units that fail to meet the company's specifications, and we can estimate this with:

$\hat p = \frac{24}{250}= 0.096$

The margin of error is the range of values below and above the sample statistic in a confidence interval.

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 confidence interval for a proportion is given by this formula

$\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}$

For the 98% confidence interval the value of $\alpha=1-0.98=0.02$ and $\alpha/2=0.01$ , with that value we can find the quantile required for the interval in the normal standard distribution.

$z_{\alpha/2}=2.33$

And the margin of error would be:

$ME= 2.33*\sqrt{\frac{0.096*(1-0.096)}{250}}= 0.0434$
