The probability that the proportion of persons with a retirement account in a random sample of size 555 differs from the population proportion by less than 5% is approximately 0.8327.

We need to make some assumptions about the population proportion of persons with a retirement account and the standard deviation of the sampling distribution of sample proportions. Let's assume that the population proportion is p = 0.5 (i.e., half of the population has a retirement account) and that the standard deviation of the sampling distribution is given by:

σ = sqrt((p*(1-p))/n)

where n is the sample size.

Substituting the values given in the question, we have:

σ = sqrt((0.5*(1-0.5))/555) = 0.0258

To find the probability that the sample proportion differs from the population proportion by less than 5%, we need to find the probability that the absolute difference between the sample proportion and the population proportion is less than 0.05. This can be written as:

P(|p_hat - p| < 0.05)

where p_hat is the sample proportion.

We can standardize this expression by subtracting the population proportion from both sides and dividing by the standard deviation:

P(|p_hat - p|/σ < 0.05/σ)

P(-0.97 < Z < 0.97)

where Z is a standard normal variable. We can find this probability using a standard normal table or a calculator:

P(-0.97 < Z < 0.97) = 0.8327

Rounding to four decimal places, we have:

P(|p_hat - p| < 0.05) = 0.8327

Therefore, the probability that the proportion of persons with a retirement account in a random sample of size 555 differs from the population proportion by less than 5% is approximately 0.8327.

The table that represents the function y =1/3 x + 4 is the second table. This can be seen by comparing the input and output values of the given tables.

A function defines the relationship between two variables, wherein one variable depends on the other. In other words, a function is a rule or mapping from one set of values, known as the domain, to another set of values, known as the range.

The table that represents the function y =1/3 x + 4 is the second table. This can be seen by comparing the input and output values of the given tables.

The second table's input values are (6, 9, 12) and the output values are (6, 9, 12). This is equal to the equation y = 1/3 x + 4, where 1/3 x + 4 = x.

The other tables do not represent the function y = 1/3 x + 4. For example, the first table has input values of (0, -3, -6) and output values of (4, 3, 2), which do not match the equation y = 1/3 x + 4.

The third table has input values of (0, 3, 6) and output values of (4, 6, 8), which also do not match the equation y = 1/3 x + 4.

Finally, the fourth table has input values of (3, 6, 9) and output values of (5, 7, 9). This does not match the equation y = 1/3 x + 4 either.

Therefore, the table that represents the function y =1/3 x + 4 is the second table.

Complete question:

The government published the above stem-and-leaf plot showing the number of sloths at each major zoo in the country:pls answer fast if you can :

what was the smallest number of sloths at any one zoo?

Answer:

(a) To find the mean value, we sum up all the values and divide by the number of values:

Mean = (17 + 22 + 25 + 27 + 32 + 40 + 45 + 51 + 59 + 62) / 10 = 36.0

So, the mean value is 36.0.

To find the median value, we first need to put the data set in order from smallest to largest:

17, 22, 25, 27, 32, 40, 45, 51, 59, 62

The median is the middle value of the data set, which is 36 in this case.

So, the median value is 36.0.

(b) To find the mean absolute deviation (MAD), we first need to find the deviation of each value from the mean:

|17 - 36.0| = 19.0

|22 - 36.0| = 14.0

|25 - 36.0| = 11.0

|27 - 36.0| = 9.0

|32 - 36.0| = 4.0

|40 - 36.0| = 4.0

|45 - 36.0| = 9.0

|51 - 36.0| = 15.0

|59 - 36.0| = 23.0

|62 - 36.0| = 26.0

Next, we find the mean of these deviations:

MAD = (19.0 + 14.0 + 11.0 + 9.0 + 4.0 + 4.0 + 9.0 + 15.0 + 23.0 + 26.0) / 10

MAD = 13.0

So, the mean absolute deviation for this data set is 13.0.

(c) To find the percentage of the data set that lies closer than the MAD to the mean, we count how many values are within one MAD of the mean. We have:

17, 22, 25, 27, 32, 40, 45, 51, 59, 62

The values within one MAD of the mean (36.0 +/- 13.0) are:

17, 22, 25, 27, 32, 40, 45, 51

So, 8 out of 10 values are within one MAD of the mean.

The percentage of the data set that lies closer than the MAD to the mean is:

8 / 10 * 100% = 80%

(a) To find the mean value, we sum up all the values and divide by the number of values:

Mean = (7 + 7 + 7 + 8 + 8 + 9 + 10 + 32) / 8 = 9.5

So, the mean value is 9.5.

To find the mean absolute deviation (MAD), we first need to find the deviation of each value from the mean:

|7 - 9.5| = 2.5

|7 - 9.5| = 2.5

|7 - 9.5| = 2.5

|8 - 9.5| = 1.5

|8 - 9.5| = 1.5

|9 - 9.5| = 0.5

|10 - 9.5| = 0.5

|32 - 9.5| = 22.

Answer:

The area of a circle is given by the formula A = πr², where r is the radius of the circle.

If we have two circles with radii of 6 cm and 12 cm, respectively, their areas are:

A1 = π(6 cm)² ≈ 113.1 cm²

A2 = π(12 cm)² ≈ 452.4 cm²

Therefore, the area of the largest circle is closest to 452.4 square centimeters, which corresponds to the circle with radius 12 cm.

Karla's three brothers can buy a maximum of 4 pieces of candy if they divide the money evenly.

What is division?

Division is a mathematical operation that involves splitting a quantity into equal parts or groups. It is one of the four basic arithmetic operations, along with addition, subtraction, and multiplication. Division is denoted by the symbol "÷" or "/", and it is usually expressed as a fraction or a quotient.

To solve this problem, we need to determine the amount of money represented by the shaded region. Here are the steps:

Assuming that each small square represents $0.01 and there are 143 shaded cells, the total amount of money represented by the shaded region is:

143 cells x $0.01/cell = $1.43

Now, we need to divide $1.43 evenly among Karla's three brothers to find the maximum number of pieces of candy each brother can buy.

$1.43 ÷ 3 = $0.476666...

Since we cannot buy fractional pieces of candy, we need to round down to the nearest whole number. Therefore, each of Karla's three brothers can buy a maximum of:

$0.47 ÷ $0.10/piece = 4 pieces of candy

So each of Karla's three brothers can buy a maximum of 4 pieces of candy if they divide the money evenly.

Cards are dealt from a standard shuffled deck of cards until the first ace is drawn. So the chance that the next card is a king is 0.05 percent.

            When drawing a card from a standard deck of 52 cards, the chance of drawing an ace is 4/52 or 1/13. After an ace has been drawn, there are 51 cards left in the deck, and 4 of them are kings.

           So, the probability of drawing an ace and then a king is

                     (1/13) × (4/51) = 4/663.

There are 4 different aces that could be drawn, each with the same probability of

                      (1/13) × (4/51) = 4/663,

So we multiply by 4 to account for all the possible aces that could be drawn.

Therefore, the total probability of drawing an ace and then a king is

                     (4/663) × 4 = 16/663.

         Once an ace has been drawn, there are 51 cards remaining in the deck, and only one of them is a king. Therefore, the probability of drawing a king after an ace has been drawn is 1/51.

         The probability that the next card is a king after the first ace is drawn is thus:

                    (16/663) × (1/51) = 16/33663

                                              = 1/2104.

Normal distribution, the quartiles lie at roughly 0.675 standard deviations below the mean and 0.675 standard deviations above the mean, which corresponds to 25% and 75% of the data, respectively.

To determine the number of standard deviations above and below the mean that the quartiles of any normal distribution lie, use the closest available values (the applet cannot hit every value exactly).

The quartiles of a normal distribution are separated by 1.5 IQR, where IQR is the interquartile range. In a standard normal distribution, the interquartile range spans from approximately -0.675 to 0.675, which corresponds to roughly 0.675 standard deviations above and below the mean.

To determine if the difference in years at the company between employees with a high school degree and those with an MBA is significant at the 95% confidence level, we can perform a hypothesis test for p-value.

We can run a hypothesis test to see if the difference in years spent at the organization between workers with a high school diploma and those with an MBA is significant at the 95% confidence level.

We must first specify our alternative hypothesis and null hypothesis. Our null hypothesis is that there is no discernible difference in the number of years that personnel with a high school diploma and those with an MBA have worked for the organization. Our alternate theory is that the two groups have significantly different average years of employment.

The probability of witnessing the data if the null hypothesis is correct can then be determined using a t-test. The null hypothesis can be rejected if the p-value is less than 0.05, and the difference in years spent at the company between workers with a high school diploma and those with an MBA is determined to be significant at the 95% level of confidence.

We can use a two-sample t-test to compare the means of the two groups if the data is normally distributed and the variances are identical.

If the t-test yields a p-value of less than 0.05, we can reject the null hypothesis and draw the conclusion that there is a significant difference in the number of years that employees with a high school diploma and those with an MBA have worked for the organisation. In contrast, if the p-value is higher than 0.05, we are unable to rule out the null hypothesis since there is insufficient data to support the existence of a significant difference.

After answering the prοvided questiοn, we can cοnclude that PS = circle (QR(NQ - NR))/NR, which is nοt οne οf the given οptiοns.

A circle seems tο be a twο-dimensiοnal cοmpοnent defined as such cοllectiοn οf the all pοints in a jet that becοme equidistant frοm the hub. A circle is cοmmοnly pοrtrayed with the capital "O" fοr centre and the lοwer sectiοn "r" fοr the radius, which is the distance frοm the οrigin tο any pοint οn the circle.

Girth (the distance frοm arοund circle) is given by the fοrmula 2r, where (pi) is a prοpοrtiοnality cοnstant rοughly equal tο 3.14159. The fοrmula r² calculates the circle's circumference, which refers tο the amοunt οf rοοm inside οf the circle.

Nοne οf the given οptiοns represent PS directly. Hοwever, we can use the intersecting secant theοrem tο find PS.

(NQ)(NQ+QR) = (NR)(NR+PR)

We can sοlve fοr PR tο get:

PR = (NR)(NR+PR)/(NQ+QR)

PR(NQ+QR) = (NR)(NR+PR)

PRNQ + PRQR = NR² + PRNR

PRNQ = NR² + PRNR - PRQR

PRNQ = NR(NR + PR - QR)

PR = NR(NR + PR - QR)/NQ

PR(NQ) = NR(NR + PR - QR)

PRNQ = NR(NR + PR - QR)

PRNQ - NR(PR - NR - QR) = 0

PR(NQ - NR) = NR(NR + QR)

PR = (NR(NR + QR))/(NQ - NR)

PS(PR + NR) = QR(NR + QR)

PS = (QR(NR + QR))/(PR + NR)

PS = (QR(NR + QR))/((NR(NR + QR))/(NQ - NR) + NR)

the missing dimension of the triangle is the base, which has a length of 21 feet. To find the missing dimension of the triangle, we will use the formula for the area of a triangle, which is:

Area = 1/2 x base x height

We know that the area of the triangle is 14 ft squared and the height is 6 ft. We can substitute these values into the formula and solve for the base:

14 = 1/2 x base x 6

Multiplying both sides by 2/6 (or simplifying to 1/3) gives:

14 x 3/2 = base

21 = base

Therefore, the missing dimension of the triangle is the base, which has a length of 21 feet.

This means that the triangle has a height of 6 feet and a base of 21 feet, and its area is 14 square feet. The height of a triangle is the perpendicular distance from the base to the opposite vertex, and in this case, it is given as 6 feet. The base of a triangle is the side opposite the height, and we have found that it has a length of 21 feet.

In summary, we can find the missing dimension of a triangle by using the formula for the area of a triangle and the given dimensions. In this case, we found that the missing dimension is the base, which has a length of 21 feet, and we know that the height is 6 feet.

Answer:

Step-by-step explanation:

We can use the formula for the volume of a cone:

V = (1/3) * pi * r^2 *h

where V is the volume, r is the radius of the base, and h is the height.

We know the volume and height of the cone, so we can solve for the radius:

240 = (1/3) * pi * r^2 * 5

r^2 = 240 / (pi * 5/3)

r^2 = 45.68

r = sqrt(45.68)

r = 6.76 meters (rounded to two decimal places)

Now we can use the Pythagorean theorem to find the slant height:

x^2 = r^2 + h^2

x^2 = 6.76^2 + 5^2

x^2 = 88.5276

x = sqrt(88.5276)

x = 9.4 meters

Answer:

Let's denote the first term of the sequence as a, and the common difference between consecutive terms as d.

Then, we know that the fifth term is 5, so:

a + 4d = 5

Similarly, we know that the sixth term is 2.5, so:

a + 5d = 2.5

We can solve this system of equations by subtracting the first equation from the second:

(a + 5d) - (a + 4d) = 2.5 - 5

d = -2.5

Now, we can substitute this value of d into either equation to find the value of a:

a + 4d = 5

a + 4(-2.5) = 5

a - 10 = 5

a = 15

Therefore, the first term of the sequence is 15, and the common difference is -2.5. We can use this to find the value of the second term:

a + d = 15 + (-2.5) = 12.5

Therefore, the second term of the sequence is 12.5.
