Answer:

-7

Step-by-step explanation:

y-3=-2(x+5)

So we need to put this in slope-intercept form...

y - 3 = -2x -10 (You use the distributive property)

Then shift the -3 over to meet the other constant -10 by addition.

y - 3 = -2x -10

+3 + 3

y = -2x -7 since y = mx + b is in slope intercept form m = slope and b = y intercept, therefore the y intercept is -7

Use green’s theorem to evaluate

Georgia [21]

By Green's theorem (all the conditions are met), we have

$\displaystyle \int_C \sqrt y \, dx + \sqrt x \, dy = \iint_D \frac{\partial(\sqrt x)}{\partial x} - \frac{\partial(\sqrt y)}{\partial y} \, dx \, dy$

where D is the interior of the path C, or the set

$D = \left\{ (x, y) : 0 \le y \le \dfrac{x^2}2 \text{ and } 0 \le x \le 2 \right\}$

So, the line integral reduces to the double integral,

$\displaystyle \frac12 \int_0^2 \int_0^{\frac{x^2}2} x^{-\frac12} - y^{-\frac12} \, dy \, dx$

$\displaystyle = \frac12 \int_0^2 x^{-\frac12}\left(\frac{x^2}2\right) - 2\left(\frac{x^2}2\right)^{\frac12} \, dx$

$\displaystyle = \frac12 \int_0^2 \frac12 x^{\frac32} - \sqrt 2 \, x \, dx$

$\displaystyle = \frac14 \int_0^2 x^{\frac32} - 2\sqrt 2 \, x \, dx$

$\displaystyle = \frac14 \left(\frac25\cdot2^{\frac52} - \sqrt2\cdot2^2\right) = \boxed{-\frac{3\sqrt2}5}$

Answer: 0.3821

Step-by-step explanation:

Let x be the random variable that represents the wages.

Given: Workers have an average wage of $9.00 per hour with a standard deviation of $0.50.

The probability of obtaining a sample mean less than or equal to $8.85 per hour:

$P(X$

The required probability = 0.3821
