A model of a skyscraper is 1.6 in long, 2.8 in wide, and 11.2 in high. The scale factor is 8 in : 250 ft. What are the actual di

mensions of the skyscraper? (Explain if possible)

<span>At 8in to 250 feet the skyscraper converts to the following. 1.6 in/8 in x 250ft = 50 ft long 2.8in/8in x 250ft = 87.5 ft wide 11.2in/8in x 250ft = 350 ft high You get this because every 8 in is 250 feet so you need to calculate the ratio of scale to that 8in per 250 feet.</span>

Help with 25,27,and 28
dedylja [7]

Answer:

For 25, the answer is C

Step-by-step explanation:

How I got the answer for 25 is:

To find the mean absolute deviation of the data, start by finding the mean of the data set.

How you do this is first you need to find the sum of the data values, (add all the numbers together) and divide the sum by the number of data values.(and divide that number by how many numbers you added together in the first place)

In this case, we'd be adding 44 + 39 + 47 + 38 + 38 + 41 + 40, and that equals 287. Now we'll divide 287 by how many numbers we added together, which is 7 numbers. 287 ÷ 7 = 41. That's the mean of the data set.

Next, we'll find the absolute deviation of the mean. How we do this is, we find how far away all the numbers are from 41.

44 is 3 away from 41

39 is 2 away from 41

47 is 6 away from 41

38 is 3 away from 41

41 is 0 away from 41

40 is 1 away from 41

So now, we add all of the distances together (3, 2, 6, 3, 0, and 1), and that equals 15! Now we do 15 ÷ 6, which is 2.5 and the reason we're dividing by 6 is because we're dividing by the number of distances we added together. Now, if you look on your worksheet, the closest answer to 2.5 is C, (2.6) so I'd chose that as the correct answer. I hope that helped!

Find the equation of the least squares regression line. Show all calculations, and be sure to define any variables used.
spayn [35]
Steps
Step 1: For each (x,y) point calculate x2 and xy.
Step 2: Sum all x, y, x2 and xy, which gives us Σx, Σy, Σx2 and Σxy (Σ means "sum up")
Step 3: Calculate Slope m:
m = N Σ(xy) − Σx Σy N Σ(x2) − (Σx)2
Step 4: Calculate Intercept b:
b = Σy − m Σx N.
Step 5: Assemble the equation of a line.

If two 6-sided dice are rolled, what is the<br> probability of rolling double 2s?
Komok [63]

16.7%

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.

What is 2/4 + 4/5 - 7/10 ? Please help
Radda [10]
Make sure they have all common denominators
\frac{2}{4} + \frac{4}{5} - \frac{7}{10}

\frac{2}{4} * \frac{5}{5} = \frac{10}{20}

\frac{4}{5} * \frac{4}{4} = \frac{16}{20}

\frac{7}{10} * \frac{2}{2} = \frac{14}{20}

\frac{10}{20} + \frac{16}{20} - \frac{14}{20}

Add \frac{10}{20} + \frac{16}{20} = \frac{26}{20}
\frac{26}{20} - \frac{14}{20} = \frac{12}{20}

To simplify, you must find the largest common factor which 4
In \frac{12}{20}
12÷4=3 and 20÷4=5

The answer is \frac{3}{5}
