Answer:Variance: 438.2380952380951

Step-by-step explanation:First, I added up all of the numbers:5 + 13 + 32 + 37 + 49 + 51 + 63 = 250

I squared the total, and then divided the number of items in the data set250 x 250 = 62500

62500 / 7 = 8928.57142857143

I took my set of original numbers from step 1, squared them individually this time, and added them all up:(5 x 5) + (13 x 13) + (32 x 32) + (37 x 37) + (49 x 49) + (51 x 51) + (63 x 63) = 11558

I subtracted the amount in step 2 from the amount in step 3:11558 - 8928.57142857143 = 2629.4285714285706

I subtracted 1 from the number of items in my data set:7 - 1 = 6

I divided the number in step 4 by the number in step 5:2629.4285714285706 / 6 = 438.2380952380951

This is my Variance!

What is the domain of f(x)=3^x
zimovet [89]

Answer:

B

Step-by-step explanation:

This is an exponential function. These types of functions have asymtotes. Asymtotes are when x or y is approaching a specific value, but it's not touching it. If you put your function in a graphing calculator, you will find that the y is approaching 0, but it's not quite touching it. What we're looking for, however is domain (x), and there are no asymtotes for x because as you can see, every value on the x axis has a y point. Therefore the domain is all real numbers.

Big ideas math 1.2 Practice A number 19
slega [8]

By applying Segment Addition Postulate, segment FH is equal to 24 units.

<h3>What is a point?</h3>

A point can be defined as a zero dimensional geometric object and it is generally represented by a dot.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

<u>Given the following data:</u>

  • Line segment FG = 37.
  • Segment HG = 13.

Since point H lies on line segment FG, we would apply Segment Addition Postulate to determine segment FH as follows:

FG = HG + FH

37 = 13 + FH

FH = 37 - 13

FH = 24 units.

Complete Question:

Given that line segment FG = 37 and segment HG = 13, find segment FH.

7. Find the distance between the points (13, 8) and (-12, 6)
Alik [6]

9514 1404 393

Answer:

  √629 ≈ 25.08

Step-by-step explanation:

The distance formula is useful for this.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((-12 -13)² +(6 -8)²) = √(625 +4) = √629 ≈ 25.08

The distance between the points is about 25.08 units.
