Jada has a coin jar containing $$n$$ nickels and $$d$$ dimes worth a total of $3.65. The equation $$0.05n + 0.1d = 3.65$$ is one way to represent this situation. Which equation is equivalent to the equation $$0.05n + 0.1d = 3.65$$ ?

Select all the equations that have the same solution as $$2x - 5 = 15$$ .

The number of hours spent in an airplane on a single flight is recorded on a dot plot. The mean is 5 hours and the standard deviation is approximately 5.82 hours. The median is 4 hours and the IQR is 3 hours. The value 26 hours is an outlier that should not have been included in the data. When the outlier is removed from the data set: What is the mean?

What is the standard deviation?

What is the median?

What is the IQR?

A basketball coach purchases bananas for the players on his team. Which equation could represent the total price in dollars for $$n$$ bananas?

Kiran is collecting dimes and quarters in a jar. He has collected $10.00 so far and has $$d$$ dimes and $$q$$ quarters. Select all the values $$(d, q)$$ that could be solutions to the equation $$0.1d + 0.25q = 10$$ .
