Hey there!

Here is your answer:

<u><em>The proper answer to this question is "510".</em></u>

Reason:

Just look at it this way:

<u><em>15% of 3,400</em></u>
<u><em>510</em></u><span><u><em>15 x 3400</em></u><u><em>100</em></u></span><u><em> = 510</em></u>

<em>Therefore 15% of 3,400 is 510!</em>

If you need anymore help feel free to ask me!

Hope this helps!

Find the area of the composite figure.
vivado [14]

So in fig 1 :

  • L = 14m
  • W = 9m

  • Area = L × W
  • Area = 9 × 14
  • Area = 126 m²

In fig 2 :

  • L = 7m
  • W = 16 - 9 = 7m

  • Area= L × W
  • Area = 7 × 7
  • Area =49m²

  • TA = 126 + 49
  • TA = 175 m²

Does anyone know a edulastic hack?
poizon [28]

Answer: The Pacing Method:

Use Edulastic to help convey weekly expectations and track student progress along the way

You can set up Edulastic to function as your check-in-tool with students, and Edulastic will help you in gathering student data during this process (#Edulasticforthewin!). This can help in estimating student participation grades and preparing reports to supervisors. It can also help with pacing and students staying on task.

When I was a high school science teacher I would structure “Check ins” with my students on written handouts that students had to present to me for my signature (upon meeting and discussing project updates, hearing feedback from me etc.). If I had access to Edulastic tools then, I could have instead coordinated these check ins digitally and privately using Edulastic. They could check-in on their own time, at home or at school. That makes things a heck of a lot more efficient than having students form a line waiting to talk to me at my desk! You can set this up to occur at the every other day mark, weekly mark, biweekly, or even monthly mark depending upon length and scope of a project in place.

Check out how this might look in Edulastic:

What is the mean of Variable A? Express answer to one decimal place. Scatter plot on a first quadrant coordinate grid. The horiz
ivanzaharov [21]
Variable A is x. Variable B is y. (x,y)

2 , 2, 4, 5, 6, 7, 8, 9

Mean is computed by adding all the numbers in the data set and dividing it by its count.

2 + 2 + 4 + 5 + 6 + 7 + 8 + 9 = 43

43 / 8 = 5.375 rounded to 5.4

NemiM [27]

Answer:

Standard error = 0.4

Step-by-step explanation:

Step 1

We find the Standard Deviation

The formula = √(x - mean)/n - 1

n = 15

Mean = 1.93 hours

= √(0- 1.93)² + (0-1.93)² +(0- 1.93)²+( 0- 1.93)²+ (1- 1.93)² + (1- 1.93)² +(1 - 1.93)² +(2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + ( 2 - 1.93)² +(4 - 1.93)² +(4 - 1.93)² + (5 - 1.93)²/15 - 1

= √(3.737777776 + 3.737777776 + 3.737777776 + 0.871111111 +0.871111111 + 0.871111111 + 0.004444444445+ 0.004444444445 + 0.004444444445 + 0.004444444445 + 0.004444444445 + 1.137777778 + 4.271111112 + 4.271111112 + 9.404444446)/15 - 1

= √2.352380952

= 1.533747356

Step 2

We find the standard error

The formula = Standard Deviation/√n

Standard deviation = 1.533747356

n = 15

= 1.533747356/√15

= 1.533747356 /3.87298334621

= 0.39601186447

Approximately = 0.4

Therefore, the standard error is 0.4
