Step-by-step explanation:

y - x = 3x +2

y=3x+x+2

y=4x+2.......(1)

2x + 2y = 14 - y

2x+2y+y=14

2x+3y=14.........(1)

substituting value of y in equation 1

2x+3(4x+2)=14

2x+12x+6=14.

14x=14-6

14x=8

x=8/14=4/7

substituting value of x in equation 1

y=4×4/7+2=30/7

x=4/7

y=30/7

Ignacio is curious about the average age of cars in the commuter lot at Mis large university. He takes a random
spin [16.1K]

Answer:

Between 12.614 years and 16.386 years

Step-by-step explanation:

Given that:

Mean age (μ) = 14.5 years, standard deviation (σ) = 4.6 years, number o sample (n) and the confidence interval (c) = 90% = 0,9

α = 1 -c = 1 -0.9 = 0.1

\frac{\alpha }{2}  = \frac{0.1}{2} = 0.05

The z score of \alpha /2 is the same as the z score of 0.45 (0.5 - 0.05). This can be gotten from the probability distribution table. Therefore:

z_{0.05}=1.64

The margin of error (e) = z_{0.05}\frac{\sigma}{\sqrt{n} } = 1.64*\frac{4.6}{\sqrt{16} }=1.886

The interval = μ ± e = 14.5 ± 1.886 = (12.614 ,16.386)
