<u>Answer:</u>

The value of tan(G) in the  right triangle GYK Is \sqrt{3}

<u>Step-by-step explanation:</u>

Given

Measure of angle at G=60^{\circ}

Measure of angle at Y=30^{\circ}

Measure of angle at K=90^{\circ}

To find:

\tan (G)=?

Solution:

In trigonometry we know that

\tan G=\frac{\sin G}{\cos G}

G=60^{\circ}

So,

\sin (60)=\frac{\sqrt{3}}{2}

\cos (60)=\frac{1}{2}

Substituting in the formula we have,

\tan G=\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}

\tan G=\frac{\sqrt{3}}{2} \times \frac{2}{1}

\tan G=\frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}

\tan G=\sqrt{3}

Result:

Thus the value of \tan G=\sqrt{3}

Answer:

The answer is \sqrt{3

Step-by-step explanation:

Tan(G) = <u>opposite side</u>

              adjacent side

Tan(G) = \frac{\sqrt{3} }{1}

Tan(G) = \sqrt{3}

Method for constructing the circle that inscribed a triangle
AleksAgata [21]

Answer:

Radius = incenter → peprpendicular to one side of the triangle

Step-by-step explanation:

  1. Bisect one of the angles
  2. Bisect another angle
  3. Where those two lines cross is the center of the inscribed circle, called the incenter
  4. Construct a perpendicular from the center point to one side of the triangle
  5. Place compass on the center point, adjust its length to where the perpendicular crosses the triangle, and draw your inscribed circle!

artcher [175]

Answer:

  • 120 g

Step-by-step explanation:

A salt solution contains 10% salt and weights 80g.

<u>Salt content of the solution is:</u>

  • 80*0.1 = 8 g

<u>4% solution has 8 g salt, total solution is:</u>

  • 0.04x = 8
  • x = 8/0.04 = 200 g

<u>Water to be added:</u>

  • 200 - 80 = 120 g

An automobile manufacturer has given its car a 52.6 miles/gallon (MPG) rating. An independent testing firm has been contracted t
Arte-miy333 [17]

Answer:

Null hypothesis:\mu = 52.6  

Alternative hypothesis:\mu \neq 52.6  

z=\frac{52.8-52.6}{\frac{1.6}{\sqrt{250}}}=1.976    

p_v =2*P(z>1.976)=0.0482  

Since the p value is lower than the significance level wedon't have enough evidence to conclude that the true mean is significantly different from 52.6 MPG.

Step-by-step explanation:

Information provided

\bar X=52.8 represent the sample mean  for the MPG of the cars

\sigma=1.6 represent the population standard deviation

n=250 sample size  of cars

\mu_o =52.6 represent the value that we want to test

\alpha=0.05 represent the significance level for the hypothesis test.  

z would represent the statistic (variable of interest)  

p_v represent the p value for the test

Hypothesis

We need to conduct a hypothesis in order to check if the true mean of MPG is different from 52.6 MPG, the system of hypothesis would be:  

Null hypothesis:\mu = 52.6  

Alternative hypothesis:\mu \neq 52.6  

Since we know the population deviation the statistic is given by:

z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}  (1)  

Calculate the statistic

Replacing we have this:

z=\frac{52.8-52.6}{\frac{1.6}{\sqrt{250}}}=1.976    

Decision

Since is a two tailed test the p value would be:  

p_v =2*P(z>1.976)=0.0482  

Since the p value is lower than the significance level wedon't have enough evidence to conclude that the true mean is significantly different from 52.6 MPG.
