the population density of the country Vanuatu is 44 people per square mile area of 4,710 square miles about how many people live

snow_lady [41]

44 x 4710

so... 207,240

This is because if there is 44 people in every square mile it would then be 44 x 4710

For a group of 70 people, assuming that each person is equally likely to have a birthday on each of 365 days in the year, comput

ch4aika [34]

Answer:

0.0157

Step-by-step explanation:

From the information given:

The sample size = 70

The expected no. of days of year that are birthday of exactly 4 people is: $P = \bigg [ \dfrac{1}{365} \bigg]^4$

The expected number of days with 4 birthdays = $\sum \limits ^{365}_{i=1} E(x_i)$

$\sum \limits ^{365}_{i=1} E(x_i) = 365 \times \bigg[ \ ^{70}C_{4} \times ( \dfrac{1}{365})^4 ( 1 - \dfrac{1}{365})^{70-4} \bigg]$

$\sum \limits ^{365}_{i=1} E(x_i) = 365 \times \bigg[ \ \dfrac{70!}{4!(70-4)!} \times ( \dfrac{1}{365})^4 ( 1 - \dfrac{1}{365})^{66} \bigg]$

$\sum \limits ^{365}_{i=1} E(x_i) = 365 \times \bigg[ \ 916895 \times 5.6342 \times 10^{-11} \times 0.8343768898 \bigg]$

= 0.0157

Therefore, the required probability = 0.0157

Convert 320cm^3 to m^3 and mm^3

madam [21]

<h2>Dimensional Analysis</h2><h3>Answer:</h3>

$320\text{cm}^3$ is $\bold{0.00032\text{m}^3}$ if written in $\text{m}^3$
$320\text{cm}^3$ is $\bold{320000\text{mm}^3}$ if written in $\text{mm}^3$

<h3>Step-by-step explanation:</h3>

Rewriting $320cm^3$ in $m^3$ :

$320\text{c\text{m}}^3 \\ 320\text{c\text{m}}^3 \cdot \frac{\text{m}}{100\text{c\text{m}}} \\320\text{c\text{m}}^3 \cdot (\frac{\text{m}}{100\text{c\text{m}}})^3 \\ 320\text{c\text{m}}^3 \cdot \frac{\text{m}^3}{100^3 \cdot \text{c\text{m}}^3} \\ 320\text{c\text{m}}^3 \cdot \frac{\text{m}^3}{1000000\text{c\text{m}}^3} \\ \frac{320\text{c\text{m}}^3 \cdot \text{m}^3}{1000000\text{c\text{m}}^3} \\ \frac{32\text{m}^3}{100000} \\ \frac{32}{100000}\text{m}^3 \\ 0.00032\text{m}^3$

Rewriting $320cm^3$ in $mm^3$ :

$320\text{cm}^3$ in $\text{mm}^3$ :

$320\text{cm}^3 \\ 320\text{cm}^3 \cdot \frac{\text{mm}}{0.1\text{cm}} \\ 320\text{cm}^3 \cdot (\frac{\text{mm}}{0.1\text{cm}})^3 \\ 320\text{cm}^3 \cdot \frac{\text{mm}^3}{0.1^3 \cdot \text{cm}^3} \\ 320\text{cm}^3 \cdot \frac{\text{mm}^3}{0.001\text{cm}^3} \\ \frac{320\text{cm}^3 \cdot \text{mm}^3}{0.001\text{cm}^3} \\ \frac{320\text{mm}^3}{0.001} \\ 320000\text{mm}^3$

Calculate the curved surface area of a cylindrical container 10cm diameter, length 18cm take the value of pie to 3.14

True [87]

Answer:

56.52 cm^2

Step-by-step explanation:

curved surface area = 2πrh

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

10 / 2 = 5

2 x 3.14 x5 x 18 = 56.52 cm^2
