Ashton's class were randomly asked how many text messages they sent yesterday, they answers were 1, 0, 10, 7, 13, 2, 9, 15, 0, 3; how many students were asked and how do you know?

10

Step-by-step explanation:

you count the answers given and that is the number of students asked

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
