A pentagon has 5 sides.
A hexagon has 6 sides.
If the pentagon has 5 sides that each measure 6 inches, then the perimeter would be 30 inches.
If the hexagon has 6 sides that measure 5 inches each, then the perimeter is also 30.
The shapes have the same perimeter.

Answer:

The perimeter of both shapes is equal.

Step-by-step explanation:

We have been Anthony drew a pentagon with each side measuring 6 inches.

We know that perimeter of a regular polygon is n times the side length of polygon, where n represents number of sides in a polygon.

We know that a pentagon has 5 sides, so perimeter of pentagon would be 5\times 6\text{ inches}=30\text{ inches}.

Carol drew hexagon with each side measuring 5 inches. We know that a hexagon has 6 sides, so perimeter of hexagon would be 6\times 5\text{ inches}=30\text{ inches}.

Therefore, the perimeter of both shapes is equal.

WINSTONCH [101]

Answer:

<em>(a) A 99% confidence interval for the actual mean noise level in hospitals is </em><em>(44.02 db, 49.98 db)</em><em>. </em>

<em>(b) We can be 90% confident that the actual mean noise level in hospitals is </em><em>47 db</em><em> with a margin of error of </em><em>1.89 db</em><em>. </em>

<em>(c) Unless our sample (of 81 hospitals) is among the most unusual 2% of samples, the actual mean noise level in hospitals is between </em><em>44.41 db and 49.59 db</em><em>. </em>

<em />

Step-by-step explanation:

<em>The problem is incomplete. The questions are:</em>

<em />

<em>(a) A 99% confidence interval for the actual mean noise level in hospitals is </em><em>(44.02 db, 49.98 db)</em><em>. </em>

For a 99% CI, the value of z is z=2.58

Then, the confidence interval for the mean is:

M-z\sigma/\sqrt{n}\leq\mu\leq M-z\sigma/\sqrt{n}\\\\47-2.58*10/\sqrt{75}  \leq\mu\leq47+2.58*10/\sqrt{75}\\\\47-2.98\leq\mu\leq47+2.98\\\\44.02\leq\mu\leq 49.98

<em>(b) We can be 90% confident that the actual mean noise level in hospitals is </em><em>47 db</em><em> with a margin of error of </em><em>1.89 db</em><em>. </em>

For a 90% CI, the value of z is z=1.64.

Then, we can calculate the margin of error as:

E=z*\sigma/\sqrt{n}=1.64*10/\sqrt{75}=1.89

<em>(c) Unless our sample (of 81 hospitals) is among the most unusual 2% of samples, the actual mean noise level in hospitals is between </em><em>44.41 db and 49.59 db</em><em>. </em>

The 2% tails data corresponds, in the standard normal distirbution, to the values of z whose absolute value is higher than 2.33.

The values of db for these critical values are:

X_1=M+z_1*\sigma/\sqrt{n}=47+(-2.33)*10/\sqrt{81}=47-2.59=44.41\\\\\\ X_2=M+z_2*\sigma/\sqrt{n}=47+(2.33)*10/\sqrt{81}=47+2.59=49.59

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

4x + y = 2

y = x - 3

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    4x + (x - 3) = 2
  2. Combine like terms:           5x - 3 = 2
  3. Isolate <em>x</em> term:                     5x = 5
  4. Isolate <em>x</em>:                              x = 1

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = x - 3
  2. Substitute in <em>x</em>:                       y = 1 - 3
  3. Subtract:                                 y = -2
