The combined land area of the countries A and B is 159159,973 square kilometers. Country A is larger by 473473 square kilometer

lora16 [44]

Answer:

The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

Step-by-step explanation:

Let the area of Country B be x

We are given that Country A is larger by 473 square kilometers.

Area of Country A = x+473

Total area of both countries = x+x+473

Total area of both countries = 2x+473

We are given that The combined land area of the countries A and B is 159,973 square kilometers.

So, $2x+473=159973$

$2x=159973-473$

$x=\frac{159973-473}{2}$

x=79750

Area of Country A = x+473=79750+473=80223 sq.km.

Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

Philip Morris wishes to determine if there is a difference between the proportion of women and proportion of men who smoke cigar

uranmaximum [27]

Answer:

Step-by-step explanation:

This is a test of 2 population proportions. Let 1 and 2 be the subscript for the women and men who smoke respectively. The population proportion of women and men who smoke would be p1 and p2 respectively.

p1 - p2 = difference in the proportion of women and men who smoke.

The null hypothesis is

H0 : p1 = p2

p1 - p2 = 0

The alternative hypothesis is

Ha : p1 > p2

p1 - p2 > 0

it is a right tailed test

Sample proportion = x/n

Where

x represents number of success(number of complaints)

n represents number of samples

For women

x1 = 14

n1 = 110

p1 = 14/110 = 0.13

For men,

x2 = 7

n2 = 95

p2 = 7/95 = 0.07

The pooled proportion, pc is

pc = (x1 + x2)/(n1 + n2)

pc = (14 + 7)/(110 + 95) = 0.1

1 - pc = 1 - 0.1 = 0.9

z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)

z = (0.13 - 0.07)/√(0.1)(0.9)(1/110 + 1/95)

z = 1.47

From the options given, the test statistic is

e. none of these is correct.

Since it is a right tailed test, we will look at the area to the right of z = 1.47. The p value would be

p value = 1 - 0.9292 = 0.078

Since alpha, 0.005 < than the p value, 0.078, then we would fail to reject the null hypothesis. Therefore, the data does not indicate that the proportion of women who smoke cigarettes is higher than the proportion of men who do at α=.005

Gabriel determined that his total cost would be represented by 2. 5x 2y – 2. His sister states that the expression should be x x

lisabon 2012 [21]

The equations of both the sister are the same.

<h2>Expression </h2>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.

<h2>Given to us</h2>

Gabriel Equation: $2.5x+2y-2$ ,

Gabriel's Sister Equation: $x+x+0.5x+y+y-2$ ,

<h3>Gabriel's Sister Equation</h3>

On further solving the equation we get,

$x+x+0.5x+y+y-2\\=2.5x + 2y-2$

As we can see the equation transformed to Gabriel's Equation of total cost.

Therefore, both the sisters are correct as the equations of both the sister are the same.

A movie club charges a one-time

Mama L [17]

Answer:

Step-by-step explanation:

Club A charges $30 membership fee and charges $7 for each movie.

You can write this as :

A = 30 + 7m (where m = number of movies)

Club B charges no membership fee and it costs $12 for each movie.

B = 12m

If we want to find how many movies a member must purchase for the total cost of the two clubs to be the same, this means we are trying to solve for "m" (number of movies) when A = B.

30 + 7m = 12m

Now you can just subtract 7m from both sides.

30 = 5m

Divide both sides by 5 to find "m'.

m = 30/5 = 6

Therefore a member must purchase 6 movies
