If the point (a,3) lies on the graph of the equation 5x + y = 8 then a =?

Mathematics

Contact [7]3 years ago

Answer:

a = 1

Step-by-step explanation:

Given the point (a, 3) is on the line: 5x + y = 8.

Any point on the line satisfies the equation.

So, (a, 3) should satisfy the equation 5x + y = 8

Substituting x = a and y = 3, we get:

5(a) + 3 = 8

$ \implies 5a = 5 $

⇒ a = 1

Therefore, (1, 3) is the point on the line.

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

A tortoise walks 3 inches in 1 second. How many feet per second can the tortoise walk?
den301095 [7]
Set up the conversion factor like this:

\frac{3in}{1} * \frac{1ft}{12in}

The inches are in the denominator while the feet are in the numerator in the conversion factor.  It's set up this way because the numerators and denominators have to be able to cancel out.  In this case, the inches would cancel out, and you would end up with 3/12 feet, which is also 0.25 feet.  The turtle walks 0.25 feet per second.
