To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.

40% of the groups budget was spent on activities. If $64,000 was spent on the activities, what was the full budget? solve with t
Andre45 [30]

Answer:

The full budget has a total value of $160,000

Step-by-step explanation:

This is a simple ratio problem and can be solved using the Rule of Three property. The Rule of Three is used to compare two ratios and find the missing part. In this case the ratios would be the following.

\frac{64,000}{40 percent} = \frac{x}{100 percent}

\frac{64,000 * 100 percent}{40 percent} = \frac{x}

\frac{6,400,000}{40 percent} = \frac{x}

160,000= \frac{x}

So now we know that 100% (The full budget) has a total value of $160,000.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
