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!} $[/tex]
[tex]$=\frac{13 !}{7! \times 2! \times 2! \times 2!}$[/tex]
= 120 number of ways

The mean June midday temperature in Desertville is 36°C and the standard deviation is 3°C.Assuming this data is normally distributed, how many days in June would you expect the midday temperature to be between 39°C and 42°C?
Answers
Answer:
The value is [tex]E(X) = 4 \ days[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 36^oC[/tex]
The standard deviation [tex]\sigma = 3^oC[/tex]
Generally the probability that in June , the midday temperature is between
39°C and 42°C is mathematically represented as
[tex]P(39 < X < 42) = P(\frac{39 - 36}{3} < \frac{X - \mu }{\sigma} < (\frac{42 - 36}{3} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(39 < X < 42) = P(1 < Z <2 )[/tex]
=> [tex]P(39 < X < 42) = P(Z < 2) - P( Z <1 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1 and 2 is
P(Z < 2) = 0.97725
and
P(Z < 1) = 0.84134
[tex]P(39 < X < 42) = 0.97725 - 0.84134[/tex]
=> [tex]P(39 < X < 42) = 0.13591[/tex]
Generally number of days in June would you expect the midday temperature to be between 39°C and 42°C
[tex]E(X) = n * P(39 < X 42 )[/tex]
Here n is the number of days in June which is n = 30
[tex]E(X) = 30 * 0.13591[/tex]
=> [tex]E(X) = 4 \ days[/tex]

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]

Ronny is taking a jar with 50 dimes and quarters to Coin Master to redeem for dollar bills. The total value of his jar is $8.
Complete the system of equations below to represent the number of quarters, q, and the number of dimes, d, in the jar
Answers
8 = .10d + .25q so that d+q=50
The required system of the equation that represents the number of quarters, q, and the number of dimes, d, in the jar is 0.10d + 0.25q = 8 and d + q = 50.
Given that,
Ronny is taking a jar with 50 dimes and quarters to Coin Master to redeem for dollar bills. The total value of his jar is $8.
Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let the number of the dimes be d and the number of the quarters be q,
According to the question,
The total of the coins is 50,
d + q = 50,
And this coins values is $8,
0.10d + 0.25q = 50 [sinnce value of one dime = 0.10 and value of one quarter is 0.25]
Thus, the required system of the equation that represents the number of quarters, q, and the number of dimes, d, in the jar is 0.10d + 0.25q = 8 and d + q = 50.
