Answer:
9 + 8 + 12 = 29
Step-by-step explanation:
Answer:
correct answer comes out to be option D
Step-by-step explanation:
sample mean (μ) = $150
standard deviation (σ) = $20
for about 95% of monthly food expenditure are between
= μ - 2 σ , μ + 2 σ
= $150 - 2 × $20 , $150 + 2 × $20
= $110 , $ 190
so, the range comes out to be in between $110 and $ 190.
Hence, the correct answer comes out to be option D.
Well one is a triangle! and another is a hexagon!
Answer:
f(x) = (x − 3)² − 11
Step-by-step explanation:
To convert to vertex form, complete the square.
f(x) = x² − 6x − 2
f(x) = x² − 6x + 9 − 9 − 2
f(x) = (x − 3)² − 11
Answer: Yes
Step-by-step explanation:
They are proprtoinal because the x goes up by y, while and y goes up by one
