B
It is ten times greater.
С
It is one hundred times greater
The values of the digits are the same.

Answers

Answer 1

Answer:

Option (B)

Step-by-step explanation:

Given number is 6642.

Number at ones place = 2

Number at tens place = 4

Number at hundredth place = 6

Number at thousand place = 6

Value of the number at tens place = 4 × 10 = 40

Value of the number at hundreds place = 6 × 100 = 600

Value of the number at thousand place = 6 × 1000 = 6000

Number at thousand place = 10 × (Number at hundreds place)

Therefore, Option (B) will be the answer.

In developing their warranty policy, an automobile company estimates that over a 1-year period 17% of their new cars will need to be repaired once, 7% will need repairs twice, and 4% will require three or more repairs. If you bought two cars from this company, what is the probability that neither will need repair over a 1-year period

Answers

Answer:

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

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

2(14+6)

2(14) + 2(6)

Which equals 40.

A 190-second song is divided into 3 parts, the beginning, the middle, and the end. The beginning is 1/6 as long as the end. The middle part is 1/2 as long as the end. Find the length of each part.

The beginning is ____ seconds
The middle is _____ seconds
The end is ______ seconds

Answers

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

Answers

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.

Answers

Answer:

[tex]P(A_1) = 0.007[/tex]

[tex]P(A_2) = 0.016[/tex]

[tex]P(A_3) = 0.008[/tex]

[tex]P(A_4) = 0.004[/tex]

[tex]P(A_5) = 0.0002[/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]

Ellie read an article claiming that 10% of people in her county were senior citizens, and she thought that it may be higher for residents in her city. She took a random sample of 225 people from her city and found that 36 of them were senior citizens. She wants to test H0:p=0.10 versus Ha:p > 0.10, where p is the proportion of people in her city that are senior citizens. Assuming that the conditions for inference have been met.

Required:
Calculate the test statistic for Ellie's significance test.

Answers

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]

Determine the convergence or divergence of the sequence with the given nth term. If the sequence converges, find its limit. (If the quantity diverges, enter DIVERGES.) an

Answers

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.

You play a game using fair dice and fair coins. First you flip 72 coins. For each coin that is a heads, you roll 5 six-sided dice. You sum all the six-sided dice you roll to calculate your total score. What is the expected total score from this game

Answers

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
