Answer:

<u>The variance of the sample data is 134.8339 kg²</u>

Step-by-step explanation:

Let's recall that the Standard deviation of a sample or population is the square root of the Variance, therefore:

Standard deviation = √Variance

Standard deviation² = (√Variance)²

Standard deviation² = Variance

Replacing with the value we have:

11.6118 * 11.6118 = Variance

Variance = 134.8339 kg²

<u>The variance of the sample data is 134.8339 kg²</u>

What is the sum of all the integers between 19 and 77
victus00 [196]
Think of it this way: Lets add numbers in pairs, starting at the very outer 2 numbers (19 and 77)  then go in by one and add the second number and the second to last (20 and 76), then (21 and 75) and so on.  The sum of all of these pairs are all the same: 96.  How many 96s will we have?  Well since we're coming from each end toward the middle adding pairs we will have half the distance between 19 and 77, that is (77-19)/2 = 29.  So we can actually just take 96*29 = 2784.  This is the sum of all numbers between 19 and 77

To do this, you can just multiply across. 3 times 1 equals 3 so your numerator is 3. 2 times 4 equals 8. Then, your answer would be 3/8. Hope this helps :)

Lauren is sewing a quilt using fabric squares.
KengaRu [80]

Answer:

x^2 + 8x + 16

Step-by-step explanation:

Given length of square x + 4.

Area of square with side S is given by S^2.

Therefore are of square with side x + 4 is given by (x + 4)^2

Area of square = (x + 4)^2\\=>(x + 4)*(x + 4)\\=> x(x + 4) + 4(x + 4)\\=> x^2 + 4x + 4x + 4*4\\=>  x^2 + 8x + 16

Thus, x2 + 8x + 16 expression represents the area of a fabric square.
