The measure of the supplement angle is fourteen times greater than its supplement

1 answer:

6 0

Let's assume you have supplement angle
$x$
Now when you talk about multiplication you can simply say...
$14x = y$
And that will give you the answer.

Trials in an experiment with a polygraph include results that include cases of wrong results and cases of correct results. Use a

hram777 [196]

Answer and Step-by-step explanation:

This is a complete question

Trials in an experiment with a polygraph include 97 results that include 23 cases of wrong results and 74 cases of correct results. Use a 0.01 significance level to test the claim that such polygraph results are correct less than 80% of the time. Identify the nullhypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution.

The computation is shown below:

The null and alternative hypothesis is

$H_0 : p = 0.80$

$Ha : p < 0.80$

$\hat p = \frac{x}{ n} \\\\= \frac{74}{97}$

= 0.7629

Now Test statistic = z

$= \hat p - P0 / [\sqrtP0 \times (1 - P0 ) / n]$

$= 0.7629 - 0.80 / [\sqrt(0.80 \times 0.20) / 97]$

= -0.91

Now

P-value = 0.1804

$\alpha = 0.01$

$P-value > \alpha$

So, it is Fail to reject the null hypothesis.

There is ample evidence to demonstrate that less than 80 percent of the time reports that these polygraph findings are accurate.

Serena is building a bookcase she cuts two pieces of wood from one board one piece is 1 7/8 feey long and another is 3.5 ft long

Vladimir79 [104]

Answer:

$\frac{43}{8}$ feet

Step-by-step explanation:

The total change is the sum of the length of two boards she cut.

First board length is 1 7/8th feet. Let's change to improper fraction:

1 7/8 = 15/8 feet

Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:

3 1/2 = 7/2 feet

Let's add the two:

$\frac{15}{8}+\frac{7}{2}\\=\frac{15+28}{8}\\=\frac{43}{8}$

The change in original board is 43/8 feet

Semenov [28]

The answer would be 1952 because the display of flag makes a right triangle so we will use Pythagorean theorem in order to find the sides and the sides total is 244 according to theorem, so we multiply by 8 to get the 8 flag display. <span />
