Solve using elimination<br><br> -3-X=0<br> -3y=-3-2x

ryzh [129]

<h2>The solution is (x, y) = (-3, -1)</h2>

<em><u>Solution:</u></em>

<em><u>Given, system of equations are:</u></em>

-3 - x = 0 --------- eqn 1

-3y = -3 - 2x -------- eqn 2

From eqn 1,

- 3 - x = 0

<em><u>Substitute x = -3 in eqn 2</u></em>

-3y = - 3 - 2(-3)

-3y = -3 + 6

-3y = 3

Thus the solution is (x, y) = (-3, -1)

Elena L [17]

Answer:

C) $826.82 to $873.18.

Step-by-step explanation:

Sample mean (M) = $850

Standard deviation (s) = $54

sample size (n) = 36

Z for 99% confidence interval (Z) = 2.576

The confidence interval is determined by the following relationship:

$M \pm Z*\frac{s}{\sqrt{n}}$

Applying the given values, the lower (L) and upper (U) values are:

$850 \pm 2.576*\frac{54}{\sqrt{36}}\\L=\$826.82\\U=\$873.18$

The answer is C) $826.82 to $873.18.
