Answer:

8.5 hrs

Step-by-step explanation:

-A 75th percentile mathematically means that  75% of the time data points are below that value and 25% of the time are above that value.

-We plot the given our data {3 12 2 3 5} to determine the 75th percentile

#We can use alcula.com to plot our boxplot.

-From the plot, we find our 75th percentile to be 8.5 hrs

Hence, 75% of the time the number of hours spent to prepare was less than 8.5hrs.

Katie bought 4 sweaters that cost the same amount and 1 shirt that cost $20. The items she bought cost a total of $160 before ta
Veronika [31]

Answer:

Each sweater costs $35.

Step-by-step explanation:

First subtract the total price ($160) by the price of the shirt ($20).

160 - 20 = 140

Now were left with $140. Since Katie bought 4 sweaters, divide 140 by 4.

140/4 = 35

This means that each sweater was $35. If you want to make sure this is correct just multiply 35 by 4 and then add the $20. You should end up with $160.

35 x 4 = 140

140 + 20 = 160
