PLEASE HELP! WAYYY OVERDUE!!!
In-s [12.5K]

Answers:

  • Red = negative skew
  • Yellow = symmetric
  • Blue = positive skew

================================================

Explanation:

A symmetric distribution is where we have the left half be a mirror copy of the right half. In other words, we have symmetry going on.

For the yellow team, note the distance between Q1 and the median is 1 unit (47-46 = 1), and so is the distance from the median to Q3  (48-47 = 1). So the box portion has perfect symmetry. You should find that the whiskers are also perfectly symmetric as well using a similar technique of finding the distances and comparing them.

Overall, the entire box-and-whisker plot for the yellow team is perfectly symmetric.

---------------

If a distribution isn't symmetric, then it's skewed in some way. If the right side is pulled longer than the left, then we consider it "skewed to the right" aka "positively skewed". So that applies to the blue team. The red team has negative skew because its left tail is longer than the right tail.

A square pyramid has base edge length 6 ft. The slant height of the pyramid is 5 ft. What is the volume of the​ pyramid?
nadya68 [22]

Answer:

V = 60 m3

Step-by-step explanation:

Volume of a square pyramid:

V = (1/3)a2h

Slant Height of a square pyramid:

By the pythagorean theorem we know that

s2 = r2 + h2

since r = a/2

s2 = (1/4)a2 + h2, and

s = √(h2 + (1/4)a2)

This is also the height of a triangle side

How do you model a decimal using a fraction
const2013 [10]

Answer:

If we have to model a decimal using fraction , This is the way you should write

 1.\rightarrow a.b_{1}=\frac{ab_{1}}{10\text{or}(10^1)}\\\\2.\rightarrow a.b_{1}b_{2}=\frac{ab_{1}b_{2}}{100\text{or}(10^2)}\\\\ 3.\rightarrow a.b_{1}b_{2}b_{3}=\frac{ab_{1}b_{2}b_{3}}{1000\text{or}(10^3)}\\\\............\\\\\text{General rule}\\\\n.\rightarrow a.b_{1}b_{2}b_{3}.......b_{n}=\frac{ab_{1}b_{2}b_{3}.....b_{n}}{1000.....0\text{or}(10^n)}
