Find the mean median and mode of the data set round to the nearest tenth 15,13,9,9,71,11,10,13,1,13

ser-zykov [4K]

Answer:

Organize: 1, 9, 9, 10, 11, 13, 13, 13, 15, 71

Mean: 16.5

Median: 12

Mode: 13

Step-by-step explanation:

Mean (average): 1+9+9+10+11+13+13+13+15+71 = 165 165/10 = 16.5

10-> how many numbers

Median (middle #): 1, 9, 9, 10, 11, 13, 13, 13, 15, 71

(11+13)/2 = 12 <---11 and 13 because there are two middle numbers, so you calculate the average of those two #s

Mode (most frequent #): 1, 9, 9, 10, 11, 13, 13, 13, 15, 71 --->13 appears the most

Anna has 3 3/4 cups of yogurt to make smoothies. Each smoothie uses 1/3 cup of yogurt. What is the maximum number of smoothies t

KiRa [710]

Turn 3 3/4 into an improper fraction, so it becomes 15/4. Then divide 15/4 by 1/3. Which would just be to multiple by the reciprocal, 15/4 times 3/1, to get 11 1/4, and since 1/4 is smaller than 1/3 the maximum number of smoothies is 11

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and

nevsk [136]

Step-by-step explanation:

Points are (8,5) and (-12,-9)

The equation of a line passing through two points is given by :

$y-y_1=m(x-x_1)\ \text{m is slope}\\\\y-5=\dfrac{y_2-y_1}{x_2-x_1}(x-8)\\\\y-5=\dfrac{-9-5}{-12-8}\times (x-8)\\\\y-5=\dfrac{7}{10}\times (x-8)\\\\10y-50=7x-56$

$-50+56=7x-10y\\\\7x-10y=6$

But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.
