A) 2x+3y=6
B) 3x-y=2
Multiplying equation B by 3
9x -3y = 6 then adding it to equation A
2x + 3y = 6
11x = 12
x = 12 / 11

2x + 3y = 6
3y = 6 -2x
y = 2 -(2/3)x
y = 2 -(2/3) * (12/11)
y = 2 -8/11
y = 14 / 11

Therefore, it has one solution

Construct the confidence interval for the population mean. c=. 95 x=6. 4 o=. 3 and n=42.

Damm [24]

The confidence interval is (63.909, 64.0907).

The confidence interval of a population mean is found using the formula:

CI = x ± z(σ/√n), where CI is the confidence interval, x is the mean, z is the z-score corresponding to the confidence level, σ is the standard deviation, and n is the population size.

In the question, we are given the confidence level, c = 95%.

Z-score corresponding to this, z = 1.96.

The mean of the population, x = 6.4.

The standard deviation of the population, σ = 0.3.

The population size, n = 42.

Thus, using the formula, the confidence interval is:

CI = 6.4 ± 1.96(0.3/√42),

or, CI = 6.4 ± 0.09073037.

Thus, the confidence interval is (64 - 0.09073037, 64 + 0.09073037), or, (63.909, 64.0907).

Jenny is comparing the cost of two packages of socks.One package has 8 pairs of socks for $12.Another package has 3 pairs of soc

EleoNora [17]

Answer:

Step-by-step explanation:

The second package costs $2 for each pair of socks. If the first package cost that much, it would be 8×$2 = $16 for 8 pairs of socks. That is not the same as $12 for 8 pairs.

Another way to look at it is the first package costs twice as much as the second, but has more than twice as many pairs of socks. That means the rates are not equivalent.
