Degger [83]

Answer:

618,000 might be the exact population of Vermont in 2008

Step-by-step explanation:

* Lets explain the rule of rounding to the nearest ten thousands

- To round numbers to the nearest ten thousand, make the

numbers whose last four digits are 0001 through 4999 into the

next lower number that ends in 0000

- Ex: 83,525 rounded to the nearest ten thousand would be

80,000.

- Numbers that have the last four digits of 5000 or more should

be rounded up to the next even ten thousand

- Ex: The number 58,988 rounded to the nearest ten thousand

would be 60,000

* Lets do that in the problem

∵ The number is 620,000 after rounded to the nearest

ten thousands

∴ We can chose any number whose last four digits are 00001

through 4999 as 624,000 OR 5000 or more as 618,000

∴ 618,000 might be the exact population of Vermont in 2008

When Joey mowed lawns for 10 hours and walked dogo

ankoles [38]

The charges for mowing lawns are $5 per hour and charges for walking dogs are $3 per hour.

Step-by-step explanation:

Let,

x be the charge per hour for mowing lawns

y be the charge per hour for walking dogs

According to given statement;

10x+4y=62 Eqn 1

8x+5y=55 Eqn 2

Multiplying Eqn 1 by 5

$5(10x+4y=62)\\50x+20y=310\ \ \ Eqn\ 3$

Multiplying Eqn 2 by 4

$4(8x+5y=55)\\32x+20y=220\ \ \ Eqn\ 4\\$

Subtracting Eqn 4 from Eqn 3

$(50x+20y)-(32x+20y)=310-220\\50x+20y-32x-20y=90\\18x=90$

Dividing both sides by 18

$\frac{18x}{18}=\frac{90}{18}\\x=5$

Putting in Eqn 1

$10(5)+4y=62\\50+4y=62\\4y=62-50\\4y=12$

Dividing both sides by 4

$\frac{4y}{4}=\frac{12}{4}\\y=3$

The charges for mowing lawns are $5 per hour and charges for walking dogs are $3 per hour.

Given that the population proportion is 0.82, the Normal distribution will provide a good approximation to the true sampling dis

Drupady [299]

Answer:

Then solution as long as n ≥ 56

Step-by-step explanation:

The Normal distribution will provide a good approximation to evaluate proportion tests when the following conditions are met:

n*p₀ > 10

n*q₀ > 10

As p₀ = 0,82 q₀ = 0,18 n = 13 30 56 and 100

We test:

A) n = 13 n*q₀ = 13*0,18 = 2,34 2,34 < 10

B) n = 30 n*q₀ = 30*0,18 = 5,4 5,4 < 10

C) n = 56 n*q₀ = 56 * 0,18 = 10,08

n*p₀ = 56 * 0,82 = 45,92

D) n = 100 n*q₀ = 18

n*p₀ = 82

If we test 55 we find that 55*0,18 = 9,9

Then solution as long as n ≥ 56
