ok for number 2.) 2+8+1+5+1+3+1+7+5+4+3+1=41 and 41 divided by the number of number which is 12= 3.41666666667
the mean for number 2 is 3.41666666667.
for the median you put the number from least to greatest, like so:
1, 1, 1, 1, 2, 3, 3, 4, 5, 5, 7, 8.
The middle is 3 and 3 so 3+3 divided by 2 is 6 so the median is 6.
I cant do mode but range is 8-1 divided by 2
This is what it would look like
Answer:11 question
Y=5
X=3
Perimeter =16cm
Step-by-step explanation:
2x-4= 2*3=6-4=2
Y-3 = 5-3=2
3x-5=3*3=9-5=4
Y-1=5-1=4
2*(3+5)
=2*8
=16
Answer:
x = 2, x = 8
Step-by-step explanation:
reminder that f'(x) = 
Differentiate f(x) term by term using the power rule
(a
) = na
f(x) = 
x³ - 5x² + 2x + 10
f'(x) = x² - 10x + 2
Equating f'(x) to - 14
x² - 10x + 2 = - 14 ( add 14 to both sides )
x² - 10x + 16 = 0 ← in standard form
(x - 2)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 8 = 0 ⇒ x = 8
What are we doing, adding, subtracting, multiplying.....
