After constructing a relative frequency distribution summarizing IQ scores of college students, what should be the sum of the re
saul85 [17]

Answer:

  • <u>Option</u><u> </u><u><em>A</em></u><em>. If percentages are used, the sum should be a 100%. If proportions are used, the sum should be 1.</em>

Explanation:

The <em>relative frequency</em> can be measured as a ratio (proportion) or as a percentage.

As a ratio, the relative frequency is the number of times that the desired outcome is observed (either theoretically or experimentally) divided by the total number of  possible outcomes (theoretically) or  observed (experimentally).

As a<em> percentage</em>, the relative frequency is the ratio multiplied by 100.

This shows it mathematically:

  • relative frequency of event 1 = frequency of event 1 / number of events

  • relative frequency of event 2 = frequency of event 2/number of events

  • relative frequency of event n = freqquency of event n/number of events

  • Total relative frequency = sum of of relative frequencies

                                       = sum of all (n) frequencies / number of events =

                                       = number of events / number of events = 1

As a percentage, total relative frequency = 1 × 100 = 100

Juan needs to rewrite this difference as one expression. First he factored the denominators. What step should Juan take next whe
cricket20 [7]

The next step Juan will take is to multiply the second fraction by (x-2)/(x-2).

Given that Juan needs to rewrite this difference as one expression (3x/(x²-7x+10))-(2x/(3x-15)) and factor the denominator as (3x/(x-2)(x-5))-(2x/3(x-5)).

An algebraic expression in mathematics is an expression composed of variables and constants and algebraic operations (addition, subtraction, etc.). Expressions are made up of concepts.

The given expression is (3x/(x²-7x+10))-(2x/(3x-15))

Firstly, we will factored the denominator as

(3x/(x-2)(x-5))-(2x/3(x-5)).

Now, we will multiply and divide the second fraction by (x-2), we get

(3x/(x-2)(x-5))-((2x(x-2))/3(x-5)(x-2)).

Hence, the next step when subtracting these expressions (3x/(x-2)(x-5))-(2x/3(x-5)) is multiply the second fraction by (x-2)/(x-2).

xeze [42]

Answer:

4/76 or simplified as 1/19

Step-by-step explanation:

5/20 is for the probability of the first balloon

4/19 is for the probability of the second balloon

5/20 can be simplified to 1/4 so 1/4 x 4/19 = 4/76

4/76 can also be simplified to 1/19
