A sample of 4000 persons aged 18 years and older produced the following two-way classification table: Men Women
Single 531 357
Married 1375 1179
Widowed 55 195
Divorced 139 169
Test at a 1% significance level whether gender and marital status are dependent for all persons aged 18 years and older.

Answers

Answer 1

Our calculated chi-square statistic (14.57) is greater than the critical value (11.34), we can reject the null hypothesis and conclude that gender and marital status are dependent for all persons aged 18 years and older.

To test whether gender and marital status are dependent, we need to use the chi-square test of independence. The null hypothesis is that gender and marital status are independent, and the alternative hypothesis is that they are dependent.

First, we need to calculate the expected frequencies for each cell under the assumption of independence. We can do this by multiplying the row total and column total for each cell and dividing by the grand total. For example, the expected frequency for the cell in the first row and first column is:

Expected frequency = (531 + 357) x (531 + 1375 + 55 + 139) / 4000 = 476.58

We can calculate the expected frequencies for all the cells and then use them to calculate the chi-square test statistic:

Observed           Expected          (O - E)^2 / E

             Men     Women     Men     Women

Single        531     357       476.58  411.42    2.68

Married       1375    1179      1374.00 1180.00   0.00

Widowed       55      195       62.58   53.42     2.84

Divorced      139     169       114.84  193.16    9.05

Chi-square = 2.68 + 0.00 + 2.84 + 9.05 = 14.57

The degrees of freedom for the chi-square test are (r-1) x (c-1) = (2-1) x (4-1) = 3, where r is the number of rows and c is the number of columns.

At a significance level of 1%, the critical value for the chi-square distribution with 3 degrees of freedom is 11.34. Since our calculated chi-square statistic (14.57) is greater than the critical value (11.34), we can reject the null hypothesis and conclude that gender and marital status are dependent for all persons aged 18 years and older.

In other words, there is evidence to suggest that the distribution of marital status is different for men and women.

Answers

The two points are B'=(-6,-8).

What is the plot?A plot is a graphical technique for depicting data collection, typically in the form of a graph that depicts the relationship between two or more variables. The storyline can be created either by hand or by computer. Previously, mechanical or electrical plotters were used.

To plot the points:

Plot a new point that is 8 units down and also has the same x coordinate.

Given - Point B = ( -6, 0 )

Represent the new point with B':

In Point B = ( -6, 0 )  

[tex]x=-6,y=0[/tex]

This means that B' has an x coordinate of -6.

Next, is to determine the y coordinate:

If a point (x,y) is translated b units down, the new point is (x, y, -b)

In this case:

The y coordinate of B is 0 and b = 8.

So, the new y coordinate is 0 - 8 = -8

So, we have B'=(-6,-8).

Therefore, the two points are B'=(-6,-8).

1. sonya's salary increases at a rate of 4% per year. her starting salary is $45,000. what is her annual salary, to the nearest $100, after 8 years of service?

Answers

Her annual salary after 8 years will be $57,600.

What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. It is frequently symbolized with the percent sign, " %". A % is a number with no dimensions; it has no unit of measurement.

To find what is her annual salary, to the nearest $100, after 8 years of service:

Find 4% of 45,000

[tex]\frac{x}{45000} *100=4\\\frac{x}{450} =4\\x =1800[/tex]

So, 4% of $45,000 of $1800.

1st year = $45000

2nd year = 45000 + 1800 = $46800

3rd year = 46800 + 1800 = $48600

4th year = 48600 + 1800 = $50400

5th year = 50400 + 1800 = $52200

6th year = 52200 + 1800 = $54000

7th year = 54000 + 1800 = $55800

8th year = 55800 + 1800 = $57600

Therefore, her annual salary after 8 years will be $57,600.

What is compound interest?

The interest on the a loan or deposit that is calculated using the both initial principal as well as the accrued interest from prior periods is known as compound interest (sometimes known as compounding interest).

Some features of compounding are-

Compound interest is calculated just on initial principal of a deposit or loan, which also takes into account all of the interest accrued from prior periods.The yearly interest rate is raised to a number of compounded periods minus one, and the starting principal amount is multiplied by both of these factors.The frequency plan for compounding interest can be set to be continuous, daily, or yearly.The quantity of compounding periods has a bigl impact on compound interest calculations.

Calculation for the amount after 8 years-

The principal amount is $45,000

Rate of interest is 4% per year.

Time duration is 8 years.

The formula for total amount after compounding is -

[tex]A=P\left(1+\frac{r}{n}\right)^{n t}[/tex]

A  = final amount

P  = initial principal balance

r  = interest rate

n  = number of times interest applied per time period.

t  = number of time periods elapsed.

As the rate of interest is applied only one in a year ; n = 1.

Substitute the values in the formula to get the value.

[tex]A=45,000\left(1+\frac{.04}{1}\right)^{8}\\A=45,000\left(1.04}\right)^{8}\\\\A=61585.60[/tex]

The actual distance between two cities is 333 km. What is the distance between them on the map

Answers

Answer:

d = 7.4 cm is the distance between the two cities on the map.

Step-by-step explanation:

Let d = the distance measured on the map in centimeters (cm) between any two locations and let D be the actual distance in kilometers (km) between these same two locations.

Since the scale on the map is 1 cm = 45 km, then the ratio of the distance on the map to the actual distance is equal to 1cm/45 km; therefore the quotient of any measured distance d on the map divided by the corresponding much longer actual distance D would have to maintain (equal) this same ratio; In other words, we can set up the following proportion to solve for d given the actual distance D = 333 km as follows:

1 cm/45 km = d/D

Substituting, we get:

1 cm/45 km = d/333 km

d/333 km = 1 cm/45 km

(d/333 km)(333 km) = (1 cm/45 km)(333 km)

d = (333 km/45 km)(1 cm)

d = 7.4 cm is the distance between the two cities on the map.

Check:

1 cm/45 cm = d/333 km

1 cm/45 cm = 7.4 cm/333 km

1 cm/45 cm = 1 cm/45 km (Therefore, the distance ratio of the map has been maintained

Rule 1: Multiply by 2 then add 1 starting from 1.
Rule 2: Divide by 2 then add 4 starting from 40.

I need to make an sequence for both of them and I need help

Answers

Rule 1:

1, 3, 7, 15, 31, 63, 127, 255, 511, 1023 etc

Rule 2:

40, 24, 16, 12, 10, 9, 8.5, 8.25, 8.125, 8.0625 etc

Hope this helps!

The first sequence is 1,3,7,15,31 and second sequence is 40,24,16,12,10.

Given that first rule is that multiply by 2 then add 1 starting from 1 and second rule is that divide by 2 then add 4 starting from 40.

We have to find the sequences for each rule.

We have to start from starting point and then apply the rule to find the sequence.

Sequence of rule 1:

Second term of sequence=2*1+1=3

Third term of the sequence=2*3+1=7

Fourth term of the sequence=2*7+1=15

Fifth term of the sequence=2*15+1=31.

Sequence will be 1,3,7,15,31.

Sequence of rule 2:

Second term of sequence=40/2+4=24

Third term of sequence=24/2+4=16

Fourth term of sequence=16/2+4=12

Fifth term of sequence=12/2+4=10

Sequence will be : 40,24,16,12,10.

Hence the first sequence is 1,3,7,15,31 and second sequence is 40,24,16,12,10.
