Simplify the problem 4{28-[10+(3+1)×2]}

Answer:

The  value is [tex]z = 3[/tex]

Step-by-step explanation:

From the question we are told that

   The  population proportion of senior citizens is  [tex]p  = 0.10[/tex]

   The  sample size is  [tex]n  = 225[/tex]

   The  number of senior citizens is  k =  36

   The  null hypothesis is  [tex]H_o :  p =  0.10[/tex]

    The alternative hypothesis is  [tex]H_a : p > 0.10[/tex]

Generally the sample proportion is mathematically represented as

     [tex]\^{p} =  \frac{k}{n}[/tex]

=>   [tex]\^{p} =  \frac{  36 }{225}[/tex]

=>  [tex]\^{p} =0.16[/tex]

Generally the test statistics is mathematically represented as

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

=>    [tex]z =  \frac{0.16 -  0.10 }{\sqrt{\frac{p(1 -0.10)}{225} } }[/tex]

=>    [tex]z = 3[/tex]

Step-by-step explanation:

From the question we are told that

   The number of cards selected is  n = 7

Generally in a standard deck of cards

   The total  number of cards is  N  =  52

    The number of  hearts is  h = 13  

    The  number of diamonds is  d = 13

    The number of  spade is  s  =  13

    The number of  Ace is  a = 4

    The number of kings is  k =  4

Considering question a

   The number of ways to selected 5 hearts out of the  13 hearts is mathematically represented as

      [tex]G  =  ^{13}C_5[/tex]

Here C means combination so  

The number of cards that is not hearts  is  52 -  13  =  39

Generally the number of ways of selecting the reaming 2 cards is  

    [tex]H  =  ^{39}C_2[/tex]

Generally the number of ways to select the 7  cards from the 52 deck of cards is  

        [tex]V  =  ^{52}C_7[/tex]

Generally the probability that exactly 5 of the 7 cards  are hearts is mathematically represented as

     [tex]P(A_1)  =  \frac{G  *  H}{V}[/tex]

=>  [tex]P(A_1)  =  \frac{^{13}C_5  *  ^{39}C_2}{^{52}C_7}[/tex]

=>   [tex]P(A_1)  =  0.007[/tex]

Considering question b

     The number of ways to selected 3 diamonds out of the  13 diamonds is mathematically represented as

      [tex] B =  ^{13} C_3 [/tex]

The number of ways to selected 3 hearts out of the  13 hearts is mathematically represented as

      [tex]K  =  ^{13}C_3[/tex]

The number of cards that is not hearts or diamond  is  52 -  (13 +13)  =  26

Generally the number of ways of selecting the reaming 1 cards is  

    [tex]M  =  ^{26}C_1[/tex]

Generally the probability that there are 3 hearts and 3 diamonds is

    [tex]P(A_2) =  \frac{B  *  K *  M}{V}[/tex]

=> [tex]P(A_2) =  \frac{^{13}C_3  *  ^{13}C_3 *  ^{26}C_1}{^{52}C_7}[/tex]

=>  [tex]P(A_2) = 0.016[/tex]

Considering question c

The number of ways to selected 1 spade out of the  13 spade is mathematically represented as

     [tex]J = ^{13}C_1[/tex]

Generally the probability that there are 3 hearts, 3 diamonds and 1 spade is

   [tex]P(A_3) =  \frac{B *  K  *  J}{V}[/tex]

=> [tex]P(A_3) =  \frac{^{13}C_3 *  ^{13}C_3   *  ^{13}C_1}{^{52}C_7}[/tex]

=>  [tex]P(A_3) =  0.008[/tex]

Considering question d

The number of ways to selected 2 Aces out of the  4 Aces is mathematically represented a

     [tex]U = ^{4}C_2[/tex]

The number of ways to selected 2 Kings out of the  4 Kings is mathematically represented a

       [tex]R = ^{4}C_2[/tex]

The number of cards that is not Aces or Kings  is  52 -  (4 +4)  =  44

Generally the number of ways of selecting the reaming 3 cards is  

     [tex]S = ^{44}C_3[/tex]

Generally the probability that there are 2 Aces and 2 Kings is

    [tex]P(A_4) =  \frac{U *  R  *  S}{ V}[/tex]

=>  [tex]P(A_4) =  \frac{ ^{4}C_2 *  ^{4}C_2  *  ^{44}C_3}{ ^{52}C_7}[/tex]

=>[tex]P(A_4) =  0.004[/tex]

Considering question e

The number of ways to selected 3 Kings out of the  4 Kings is mathematically represented a

     [tex]P = ^{4}C_3[/tex]

Generally the number of ways of selecting the reaming 2 cards is  

      [tex]Q = ^{44}C_2[/tex]

Generally the probability that there are 2 Aces and 3 Kings is

     [tex]P(A_5) =  \frac{U  *  P  *  Q }{V}[/tex]

=>  [tex]P(A_5) =  \frac{ ^{4}C_2  *  ^{4}C_3  *  ^{44}C_2 }{^{52}C_7}[/tex]

=>  [tex]P(A_5) =  0.0002[/tex]

Answer:

Area of rectangle = (l×b)

=14×6

=84 metre²

Perimeter of rectangle= 2×(l+b)

=2×(14+6)

=2×20

40 metre/cm {as it is not given}

Step-by-step explanation:

Hope this helps you

Crown me as brainliest

Answer:

Step-by-step explanation:

To find the area you need to multiply the two length and height.

14 x 6

This would equal 84.

For the perimeter you add all the sides. Since there are four sides to a rectangle and a square, you add 2 of the corresponding sides to the equation.

14+14+6+6

Or

2(14+6)

Or

2(14) + 2(6)

Which equals 40.

Step-by-step explanation:

OVER A 1-YEAR PERIOD, it is estimated that

17 + 7 + 4 = 28% of new cars will need repairs (ranging from one repair to infinity number of repairs)

This means that the remaining percentage of new cars will NOT need any repairs over the 1-year period.

This percentage is 100 - 28 = 72%

The question is reframed thus: If you bought 2 cars from this company, what is the probability that none of them will need repair over the 1-year period?

What is the probability that none of the 2 cars falls within the 28% of cars which will need repair in the 1-year period?

72% = 72/100 = 0.72

this is the probability that a single car will not need repairs

the probability that 2 cars from this company will not need repair over a year is  0.72 ÷ 2 = 0.36

Answer:

90.

Step-by-step explanation:

10, 9 times, means you're adding 10+10+10+10+10+10+10+10+10=90.

Answer:

630

Step-by-step explanation:

Given that:

First flip = 72 coins

For each coin which is a head, you roll = 5, six-sided dice

Thus, the expected sum on a single six-sided dice = [tex]\sum x P(x)[/tex]

[tex]\sum x P(x)[/tex] = [tex]\dfrac{1}{6}\times (1+2+3+4+5+6)[/tex]

[tex]\sum x P(x)[/tex] = 3.5

Thus, the expected sum on the five six-sided dice = 5 × 3.5 = 17.5

However, for a single flip :

The expected sum = P(heads) × expected sum on 5 dice + P(tails) × expected sum on 0 dice.

Expected sum = [tex]\dfrac{1}{2} \times 17.5 + \dfrac{1}{2} \times 0[/tex]

Expected sum = 8.75

Hence, the expected total score from this game = 72 × 8.75 = 630

Step-by-step explanation:

the correct answer is b

The sequence converges to a limit of 1/2.

We have,

Let's simplify the nth term of the sequence:

an = (n^2 + 3n) / (2n^2 + 5)

Dividing both the numerator and denominator by n^2, we get:

an = (1 + 3/n) / (2 + 5/n^2)

As n approaches infinity, the terms 3/n and 5/n^2 both tend towards zero.

Therefore, we have:

an = (1 + 0) / (2 + 0) = 1 / 2

The nth term of the sequence simplifies to a constant value of 1/2 as n approaches infinity.

Since the nth term converges to a specific value (1/2), the sequence itself is convergent.

The limit of the sequence is 1/2.

Thus,

The sequence converges to a limit of 1/2.

Answer:

The beginning part is 19 seconds.

The middle part is 57 seconds.

The end part is 114 seconds.

Step-by-step explanation:

First, you have to form expressions. Let the end part be x :

Beginning = (1/6)x

Middle = (1/2)x

End = x

Next, you have to add up altogether equals to 190 :

(1/6)x + (1/2)x + x = 190

(5/3)x = 190

x = 190 ÷ (5/3)

x = 114 s

Lastly, you have to substitute the x-value into the expressions :

Beginning = (1/6)(114) = 19 s

Middle = (1/2)(114) = 57 s

End = 114 s

Answer:

b is 19 seconds

m is 57 seconds

e is 114 seconds

Step-by-step explanation:

total = b + m + e

total = 1/6e + 1/2e + e

190 = 1/6e + 1/2e + e

190 = 10/6e

190 * 3/5 = e

114 = e

(1/6)e = b = (1/6)(114) = 19

(1/2)e = m = (1/2)(114) = 57

Answer:

They both need to work 3 hours to get the same amount of $14.

Step-by-step explanation:

If you have a graphing calculator handy, just graph the two expressions 3x + 5 and 4x + 2 and look for the point where they intersect. If you don't have a graphing calculator set up the equation 3x + 5 = 4x + 2. Subtract 4x from both sides to get -x + 5 = 2. Then subtract 5 from both sides to get -x = -3. Since x shouldn't be negative, divide both sides by -1. You do this because just like x is 1x, -x is -1x. After dividing, you should get x = 3.
