Answer:
32/81
Step-by-step explanation: multiply the numerator by 2 and the denominator by 3.
We have an equation: 1.45/?= 33/100
Cross multiply:
33*? = 1.45*100
⇒ ? = 1.45*100/33= 4.394
The final answer is 4.394~
Using it's concept, it is found that the relative frequency of 6th graders who rode a car is given by:
D. 55%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The number of 6th graders is given by:
N6 = 576 - (219 + 189) = 168.
The number of 6th graders who rode a car is:
N6C = 168 - 75 = 93
Hence the relative frequency is given by:
r = 93/168 = 55%.
Hence option D is correct.
