FOIL: first term, outer term inner term, last term
First, you should substitute the variables for their value in the expression.
= [ 3 (-0.5) (4)² - (-3) ] / (-0.5)
= [ 3 (-0.5) (4)² + 3 ] / (-0.5)
= [ 3 (-0.5) (16) + 3 ] / (-0.5)
= [ (-1.5) (16) + 3 ] / (-0.5)
= [ (-1.5) (16) + 3 ] / (-0.5)
= (-24+3) / (-0.5)
= -21 / -0.5
= 42
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!
