Answer:
Total number of pastries that will be made from at least 3/8 pound of dough is 8.
Step-by-step explanation:
It is given that the line plot shows the weight of the dough for each pastry.
From the given box plot it is clear that,
Number of pastries with weight 1/4 pound = 4
Number of pastries with weight 3/8 pound = 3
Number of pastries with weight 1/2 pound = 5
We know that
We need to find the number of pastries that will be made from at least 3/8 pound of dough. It means the number of pastries whose weight is 3/8 or more than that.
N = Number of pastries with weight 3/8 pound + Number of pastries with weight 1/2 pound
N = 3 + 5
N = 8
Therefore, total number of pastries that will be made from at least 3/8 pound of dough is 8.

Answer: mean=87, median=87.5 and range=18
Step-by-step explanation:
Mean:
First add all the numbers
78+95+77+92+87+79+94+86+88+94 = 870
Then you divide the answer by counting the numbers
870÷10
=87
Median:
First arrange the numbers in ascending order (from smallest to largest)
77, 78, 79, 86, 87, 88, 92, 94, 94, 95
pick the two middle numbers which is 87 and 88
then you do
= 175÷2
= 87.5
range = Largest number - smallest number
= 95-77
= 18
