m<GFD = 50°

m<CFD = 40°

Segment FD doesn't bisect <CFG because the angles aren't equal.

Step-by-step explanation:

<CFD and <GFD are complementary angles and their sum is 90°

-5x + 5 -7x + 1 = 90° add like terms

-12x + 6 = 90

-12x = 84 divide both sides by -12

x = -7

m<CFD is -5x + 5 ➡ (-5)×(-7) + 5 = 40°

m<GFD is -7x + 1 ➡ (-7)×(-7) + 1 = 50°

In a certain card game, only the thirteen cards that are Hearts are used, and each player is dealt a hand of just two cards. How many ways are there to deal hands of two cards each to each of three players from a 13-card deck comprised of just the Hearts?

Answers

Solution :

It is given that only 13 cards that are Hearts that is used in a certain game.

And 2 hearts to each of the 3 players.

Therefore, the number of ways is

= [tex]$^{13} C_2 \times ^{11} C_2 \times ^{9} C_2$[/tex]

[tex]$= \frac{13 !}{11 ! \times 2!} \times \frac{11 !}{9 ! \times 2!} \times \frac{9 !}{7 ! \times 2!} $[/tex]

Step-by-step explanation:

When given 2 points, it can work well to start with the 2-point form of the equation for a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (0 -(-2))/(-5 -5)(x -5) +(-2)

  y = 2/(-10)(x -5) -2

Suppose 49% of the population has a retirement account. If a random sample of size 896 is selected, what is the probability that the proportion of persons with a retirement account will differ from the population proportion by less than 3%?

Answers

Answer:

The probability is  [tex]P( |\^ p - p | < 0.03 ) = 0.9275[/tex]

Step-by-step explanation:

From the question we are told that

  The population proportion is  [tex]p = 0.49[/tex]

  The sample size is  n = 896

 Generally the standard deviation  of the sampling distribution is mathematically represented as

     [tex]\sigma_{p} = \sqrt{ \frac{p(1 -p )}{n} }[/tex]

=>  [tex]\sigma_{p} = \sqrt{ \frac{0.49(1 -0.49 )}{896} }[/tex]

=>  [tex]\sigma_{p} = 0.0167[/tex]

   Generally the the probability that the proportion of persons with a retirement account will differ from the population proportion by less than 3% is mathematically represented as

    [tex]P( |\^ p - p | < 0.03 ) = P( \frac{ | \^ p - p|}{\sigma_p } < \frac{0.03}{0.0167} )[/tex]

[tex]\frac{|\^ p - p |}{\sigma_p }  =  |Z| (The  \ standardized \  value\  of  \ |\^p - p| )[/tex]

=> [tex]P( |\^ p - p | < 0.03 ) = P(|Z| < 1.796 )[/tex]

=>  [tex]P( |\^ p - p | < 0.03 ) = P(- 1.796 < Z < 1.796 )[/tex]

=>   [tex]P( |\^ p - p | < 0.03 ) = P(1.796 < Z) - P(Z < -1.796 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1.796 and  - 1.796  is  

     [tex]P(Z < -1.796 ) = 0.036247[/tex]

    [tex]P(1.796 < Z) = 0.96375[/tex]

So

    [tex]P( |\^ p - p | < 0.03 ) = 0.96375 - 0.036247[/tex]

=>  [tex]P( |\^ p - p | < 0.03 ) = 0.9275[/tex]
