T=5

4=2+2/5t
Subtract 2 from both sides.
2=2/5t
Multiply both sides by 5/2.
t=5

Hello! Let's solve the equation step by step. :)

Step 1: Simplify both sides of the equation.<span>

4=<span><span><span>2/5</span>t</span>+2</span></span>

Step 2: Flip the equation.<span><span><span><span>

2/5</span>t</span>+2</span>=4</span>

Step 3: Subtract 2 from both sides.<span><span><span><span><span>

2/5</span>t</span>+2</span>−2</span>=<span>4−2</span></span><span><span><span>

2/5</span>t</span>=2</span>

Step 4: Multiply both sides by 5/2.<span><span><span>

(<span>52</span>)</span>*<span>(<span><span>25</span>t</span>)</span></span>=<span><span>(<span>52</span>)</span>*<span>(2)</span></span></span><span>

t=<span>5

Hope this helps! Cheerio and have a lovely day. :)</span></span>

The accompanying frequency distribution represents the square footage of a random sample of 500 houses that are owner occupied y

ioda

Answer:

$\bar X = \frac{\sum x_i f_i}{n} = \frac{1220750}{500}=2441.5$

$s^2= \frac{3408029125 -\frac{(1220750)^2}{500}}{500-1} =856849.7$

$s= \sqrt{856849.7}=925.662$

Step-by-step explanation:

For this case we can create the following table

Interval Frequency (f) Midpoint(xi) xi *f xi^2* f

0-499 9 249.5 2245.5 560252.3

500-999 13 749.5 9743.5 7302753

1000-1499 33 1249.5 41233.5 51521258.25

1500-1999 115 1749.5 201193.5 361986278.8

2000-2499 125 2249.5 281187.5 632531281.3

2500-2999 81 2749.5 222709.5 612339770.3

3000-3499 47 3249.5 152726.5 496284761.8

3500-3999 45 3749.5 168727.5 632643761.3

4000-4499 22 4249.5 93489 397281505.5

4500-4999 10 4749.5 47495 225577502.5

Total 500 1220750 3408029125

$\sum f_i = 500 , \sum x_i f_i = 1220750, \sum x^2_i f_i = 3408029125$

For this case we can calculate the sample mean with this formula:

$\bar X = \frac{\sum x_i f_i}{n} = \frac{1220750}{500}=2441.5$

And for the sample variance we can use the following formula:

$s^2= \frac{\sum x^2_i f_i - \frac{(\sum x_i f_i)^2}{n}}{n-1}$

And if we replace we got:

$s^2= \frac{3408029125 -\frac{(1220750)^2}{500}}{500-1} =856849.7$

And the deviation is just the square root of the sample variance and for this case is:

$s= \sqrt{856849.7}=925.662$
