Describe an average value of the data Ages in a class: 11, 12, 12, 12, 12, 12, 13

12

Step-by-step explanation:

To find the average, add all the numbers together...

11+12+12+12+12+12+13=84

Then divide by the number of terms, in this case 7

84/7=12

So, the average of this data is 12

Hope this helps! :)

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
