Maria was foing a assroom survey. she asked the girls in the class how many siblings they had and recorded the results: 1,2,3,6,7,9,9,9,10. determine the mean (rounded to the nearest tenth) the median, mode, and range of the results

Mean: The sum of all the numbers, divided by the amount of numbers in the set.

56 / 9 = 6.2

Median: The middle value of a set.

7

Mode: The value that occurs most frequently.

9

Range: The highest number of the set subtracted by the lowest number.

10 - 1 = 9

Hope this helps you!

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can
