Which is a better measure of spread range or interquartile range? Why?
Anvisha [2.4K]
The interquartile range (IQR) is a measure of inconstancy, in light of partitioning an informational collection into quartiles. Quartiles isolate a rank-requested informational collection into four a balance of. The qualities that gap each part are known as the primary, second, and third quartiles; and they are signified by Q1, Q2, and Q3, individually. 

Where as, measures of spread portray how comparable or changed the arrangement of watched esteems are for a specific variable (information thing). Measures of spread incorporate the range, quartiles and the interquartile range, difference and standard deviation.

Solve the inequality and write the solution set using both set-builder notation and interval notation. -3a-15≤-2a+6
Karolina [17]

Answer:

\{a ∈ R\ -21 \le  a \le \infty \} --- set builder

[-21,\infty) --- interval notation

Step-by-step explanation:

Given

-3a - 15 \le -2a + 6

Required

Solve

Collect like terms

-3a + 2a \le 15 + 6

-a \le 21

Divide by -1

a \ge - 21

Rewrite as:

-21 \le  a

Using set builder

\{a ∈ R\ -21 \le  a \le \infty \}

Using interval notation, we have:

[-21,\infty)

find the coordinates of B' after a reflection after a reflection across the parallel lines; first across the line x = 2 and then
Dvinal [7]

Answer:

  B'(-4, -1)

Step-by-step explanation:

Each reflection across x=k means the new x-coordinate is 2k-x.

Reflection across x=2:

   (x, y) ⇒ (4-x, y)

Reflection of that across x=0:

  (x, y) ⇒ (2·0 -(4-x), y) = (x-4, y)

The point is left-shifted by 4 units to ...

  B'(-4, -1)
