The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?
Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10

<h2>Repeating Decimal to Fraction</h2>
Note: "..." is the repeating sign I'm using.
Answer: 2/9
<h3>
Steps</h3>
Let X equal the decimal number
Equation 1:
X = 0.2...
With 1 digit in the repeating decimal group,
create a second equation by multiplying
both sides by 10
X * 10 = 10X and 0.2...* 10 = 2.2...
Equation 2:
10X = 2.2...
Subtract equation 1 from equation 2
10X = 2.2... - X = 0.2...
We get
9X = 2
In conclusion, 0.2... = 2/9
<h2>Repeating Decimal to Mixed Number</h2>
This decimal cannot be a mixed number because it has no number in the one's, ten's, or hundred's place.
Answer:
Step-by-step explanation:
first draw you line down on the equal sign take 2x and devide itso it should be 14/2 you should get 7 2x is no longer there then bring down 9y and add d to 14 thats 23 so its x =23
Answer:
From this finding, it can be said that the sample proportion is greater than the population proportion because the test statistic (z = 2.45) is positive.
Step-by-step explanation:
H0: p = 0.35
Ha: p > 0.35
The test is a one-tailed test because the alternate hypothesis is expressed using greater than.
The test statistic (z) for a proportion is given as (p' - p) ÷ sqrt [p(1-p)/n]
p' is sample proportion
p is population proportion
n is sample size
For the test statistic z to be positive, p' must be greater than p.
