variable is education level in this example?
Answer:
Categorical data.
Step-by-step explanation:
Variables can be classified as:
Quantitative: If the variable assumes numeric values.
Categorical: If the variable assumes labels.
In this question:
'illiterate," "primary," and "secondary" are labels, which means that in this example, education level is an example of categorical data.
Education level is a type of categorical variable.
StatisticsA categorical variable is a quantity that has been measured on a nominal scale or on an ordinal scale, but whose values do not represent measurable quantities, so cannot be summed up into totals. The values that a categorical variable can take therefore only consist of names, whether or not the names of the categories to which the values belong.

Chelsey put for $450 into an account with a simple interest rate of 2.5% when she withdrew the money she had earned a total of $67.50 in interest how long did she leave the money in the account
Answer:
5.66 years
Step-by-step explanation:
450 x 1.025^(n) = 450 + 67.50
450 x 1.025^(n) = 517.50
1.025^(n) =(517.50 / 450)
1.025^(n) = 1.15
n = ln(1.15) / ln(1.025)
n = 5.66

concert tickets cost $30,$40 or $50 if you buy a ticket online you pay an extra $3 as a booking fee. what percentage of each tickets price is the booking fee?
Answer:
$30 = 10%
$40 = 13.34%
$50 = 16.67%
Step-by-step explanation:
To find the answer you divide the cost of the ticket by the booking fee to get your answer.
The booking fee of $30 is 10%,$40 is 7.5% and $50 is 6%.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths.
The percentage of x of the y is given as,
x/y × 100
Thus, a percentage of $3 of $30 will be,
3/30 x 100 = 10%
The percentage of $3 of $40 will be,
3/40 x 100 = 7.5%
The percentage of $3 of $50 will be,
3/50 x 00 = 6%.
Hence "The booking fee of $30 is 10%,$40 is 7.5% and $50 is 6%".
