Answer:

x=3 y=-4

Step-by-step explanation:

we try to first solve for x, so we need to cancel out the y. we can multiply the first equation by 3 to get -9x-6y=-3. Then we add -9x-6y=-3 with 4x+6y=-12. The -6y and 6y cancel each other out, so we are left with -5x=-15. That means x equals 3. Since we have found x, we can plug it back into any one of the equations to find y. So, -3(3)-2y=-1. -9-2y=-1 -2y=8 y=-4. We can check this by plugging it into the other equation too. 4(3) + 6y = -12. 12 + 6y=-12. 6y=-24. y=-4.

Use z scores to compare the given values. Based on sample​ data, newborn males have weights with a mean of 3227.9 g and a standa
sasho [114]

Answer:

The weight that is more extreme is the male which is -2.62

Step-by-step explanation:

Consider the provided information.

Now use the z scores formula:

z=\frac{x-\mu}{\sigma}

Where μ is mean and σ is the standard deviation.

For newborn males have weights with a mean of 3227.9 g and a standard deviation of 659.9 g.

Substitute the respective values in the above formula.

z=\frac{1500-3227.9}{659.9}\approx-2.62

For Newborn females have weights with a mean of 3073.1 g and a standard deviation of 806.8 g.

Substitute the respective values in the above formula.

z=\frac{1500-3073.1}{806.8}\approx-1.95

So, the more extreme of these is the male which is -2.62
