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 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.
Answer:
6.12

Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is (Answer)
