Answer:

x=6

XY=24 units

YZ=18 units

Step-by-step explanation:

we have that

Y is between X and Z

$XZ=XY+YZ$

substitute the given values and solve for x

$42=4x+3x\\42=7x\\x=6$

therefore

$XY=4x=4(6)=24\ units\\YZ=3x=3(6)=18\ units$

12) Angle ACD= Angle ABC+ Angle CAB ====> You MAY end here
That is, Angle ACD= 132+21
            Angle ACD= 153

13) Angle ABC+ Angle BAC= Angle ACD====> You MAY end here
That is,     Angle ABC +16=143
                                   -16= -16
                Angle ABC=127

A class of 260 students went on a field trip. They took 12 vehicles, some cars and some buses. Find the number of cars and the n

Afina-wow [57]

The equation is 5c+25b=260 when c+b=12. rearrange that into 12-b=c. substitute and you get 5(12-b)+25b=260. b=10. 12-10=2, so 10 buses and 2 cars were used as transportation for the field trip.

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.
