What is the mean of the dot plot???​
vichka [17]

Answer:

19.5 (Rounded: 20)

Step-by-step explanation:

In math, the mean is every number added together, then divided by the amount of numbers. For example, 1,2,5,4,8 would have a median of 4.

<em>(1 + 2 + 4 + 5 + 8 = 20 ÷ 5 = 4)</em>

Your dot plot has 14 total numbers, meaning that you add up all the numbers and divide by 14.

16 + 17 + 17 + 17 + 17 + 19 + 19 + 19 + 19 + 21 + 22 + 22 + 23 + 25 = 273

273 ÷ 14 = 19.5

If you don't need to round, 19.5 is correct. However, if you need to round my best guess is 20. Good luck!

Eliah bought 1.87 pounds of chicken and 2.46 pounds of turkey at the deli. About how many pounds of meat did he buy?
mart [117]
So,

If this was mental math, I would round 1.87 to the nearest pound and 2.46 to the nearest half pound, making the following addition problem:
2 + 2.5 = 4.5
Because 1.87 is closer to 2 than to 1.5 or 1, and 2.46 is sooo close to 2.5.
So I would say about 4.5 pounds of meat.

But if you're rounding to the nearest pound for both, then you have this equation:
2 + 2 = 4
Because in 1.87, 8 is greater than or equal to 5, and in 2.46, 4 is less than or equal to 5.
So in that case, it would be about 4 pounds of meat.

Each interior angle of a regular polygon is 140°.Find the number of sides​
castortr0y [4]

Step-by-step explanation:

Each interior angle=140°

(n-2)180°/n=140°

180°n-360°/n=140°

180°n-360°=140°n

180°-140°=360°

40°n=360°

n=360°/40°

n=9

Hence, the number of sides of the polygon is 9.

It is nonagon .
