Mazyrski [523]

Answer:

Dan is correct

Step-by-step explanation:

From the question, we have:

Hours:1\ 2\ 3\ 4\ 5

Required

The average

The average hour is calculated using:

\bar x = \frac{\sum x}{n}

So, we have:

\bar x = \frac{1+2+3+4+5}{5}

\bar x = \frac{15}{5}

\bar x = 3

<em>Dan calculated the mean as 3; while Bret calculated the mean as 4.</em>

<em>Hence, we can conclude that Dan s correct</em>

(T+10.5) + 2t + 90 = 180
Masja [62]

Answer:

x = 26.5

Step-by-step explanation:

Step 1: Write equation

(t + 10.5) + 2t + 90 = 180

Step 2: Solve for <em>t</em>

<u>Combine like terms:</u> 3t + 100.5 = 180

<u>Subtract 100.5 on both sides:</u> 3t = 79.5

<u>Divide both sides by 3:</u> t = 26.5

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

<u>Substitute:</u> (26.5 + 10.5) + 2(26.5) + 90 = 180

<u>Parenthesis:</u> 37 + 56 + 90 = 180

<u>Add:</u> 180 = 180

∴ x = 26.5
