Answer:
Step-by-step explanation:
1,2,3,(4),5,6,7
median (middle number) or Q2 = 4
Q1 (lower quartile) = 2
Q3 (upper quartile) = 6
IQR = Q3 - Q1 = 6 - 2 = 4
Answer:
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Step-by-step explanation:
Point B(-6, 1) to B'(-3, -2)
Steps to achieve B"
-6+a= -3 ⇒ a= -3+6= 3
1+b= -2 ⇒ b= -2-1= -3
-----------------
Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b): B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)
- Step 2 Write two equations: Negative 6 + a = negative 2. 1 + b = negative 3.
- wrong step
Step 3 Solve each equation: Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.
Step 4 Write the translation rule: (x, y) right-arrow (x + 4, y minus 4)
----------------
- Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Answer:
The given expression will be greater than zero.
Step-by-step explanation:
If a < 0 and b < 0, then 5a^3 is < 0 (5a^3) is negative;
but b^2 is > 0.
Then (5a^3)*(b^2) < 0
and if we divide this quantity by a + b (which is negative), the end result will be > 0.
