The measure of triangle ABD is 50°

Step-by-step explanation:

Given:

Triangle ABD is formed by tangent and secant

minor arcs AC=68°, CD=124°

To find:

the measure of triangle ABD

Solution:

Angle Formed by Tangent and Secant = 1/2*(difference of Intercepted Arcs)

The intercepted arcs are AC and AD.

We know that minor arc AC + minor arc CD + minor arc AD = 360°

So using this formula AD = 360° - minor arc AC - minor arc CD

AD = 360° -68°-124°

arc AD = 168°

Substituting in the above formula,

∠ ABD = 1/2*(minor arc AD - minor arc AC)

∠ ABD =1/2*(168 - 68)

∠ABD= 50°

Answer:

33.83

Step-by-step explanation:

This is because if you trying to find h and the opposite side, you will have to use cos to get that answer. My using this equation

$\cos(31) = \frac{29}{x}$

You will find that x will equal 33.83

In 2008, the average household debt service ratio for homeowners was 13.2. The household debt service ratio is the ratio of debt

ankoles [38]

Answer:

$t=\frac{13.88-13.2}{\frac{3.14}{\sqrt{44}}}=1.436$

$df=n-1=44-1=43$

$p_v =P(t_{(43)}>1.436)=0.079$

We see that the p value i higher than the significance level so then we FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 13.2 *the value of 2008 ).

Step-by-step explanation:

Information given

$\bar X=13.88$ represent the sample mean

$s=3.14$ represent the sample standard deviation

$n=44$ sample size

$\mu_o =13.2$ represent the value that we want to test

$\alpha=0.05$ represent the significance level

t would represent the statistic (variable of interest)

$p_v$ represent the p value for the test

Hypothesis to test

We want to conduct a hypothesis in order to check if the true mean has increased from 2008 , and the system of hypothesi are:

Null hypothesis: $\mu \leq 13.2$

Alternative hypothesis: $\mu > 13.2$

The statistic for this case is:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Calculating the statistic

Replacing the info given we got:

$t=\frac{13.88-13.2}{\frac{3.14}{\sqrt{44}}}=1.436$

P-value

The degrees of freedom are:

$df=n-1=44-1=43$

Since is a right tailed test the p value is:

$p_v =P(t_{(43)}>1.436)=0.079$

a sum of money is divided among peter paul and jane in ratio 13:12:7 calculate how much paul gets if amount peter gets more than

MariettaO [177]

Paul must get 13 since Peter gets more more than Jane so Jane would get 7 and then peter would get 12

Simplify (6^7)^3 will give brainlist

pychu [463]

Answer:

The answer is D.

Step-by-step explanation:

You have to apply Indices Law,

${ ({a}^{m}) }^{n} \: ⇒ \: {a}^{mn}$

So for this question :

${ ({6}^{7}) }^{3}$

$= {6}^{7 \times 3}$

$= {6}^{21}$
