Answer:
No
Step-by-step explanation:
8−2x<12
Subtract 2 from each side
8-8−2x<12-8
-2x <4
Divide each side by -2, remembering to flip the inequality
-2x/-2 >4/-2
x > -2
Is -2 a solution
-2 >-2
This is false, it is equal
Answer:
Range = 13
Mean = 8.3
Variance = 17.61
Step-by-step explanation:
Given the population dataset :
2, 9, 15, 4, 12, 9, 13, 6, 3, 10
1.) Range : (maximum - minimum)
Maximum = 15 ; minimum = 2
Range = (15 - 2) = 13
2.) population mean (μ) :
μ = ΣX / n
n = sample size
μ = (2 + 9 + 15 + 4 + 12 + 9 + 13 + 6 + 3 + 10) / 10
μ = 83 / 10
μ = 8.3
3.) Population variance (s²)
Σ(x - μ)² / n
=[(2 - 8.3)^2 + (9 - 8.3)^2 + (15 - 8.3)^2 + (4 - 8.3)^2 + (12 - 8.3)^2 + (9 - 8.3)^2 + (13 - 8.3)^2 + (6 - 8.3)^2 + (3 - 8.3)^2 + (10 - 8.3)^2] / 10
s² = 176.1 / 10
s² = 17.61
Answer:
Step-by-s⭐Explicación paso a paso:
Aplicamos una regla de tres simple directamente proporcional, ya que entre mayor sea la cantidad de kilogramos comprados, mayor será la cantidad de dinero que se debe pagar por las manzanas (y viceversa).
Expresamos:
Kilogramos Dinero ($)
3 20
15 x
x= (15 * 20)/3
x = 300/3
x = 100$
tep explanation:
12/15. This is because 15-3 is 12. So this would equal 12/15. Sadly, you can not reduce this since 15 can’t be split into a whole number. Once again, the answer is 12/15 from what I believe..
