Answer:
(426 ; 468)
Step-by-step explanation:
Confidence interval :
Mean score ± margin of error
Margin of Error = 21
Mean SAT score = 447
Hence,
447 ± 21
Lower boundary = 447 - 21 = 426
Upper boundary = 447 + 21 = 468
(426 ; 468)
Answer:
B or 3.5 if you meant <em>1/2 as many small wreaths as medium wreaths</em>
Step-by-step explanation:
(Keep in mind you wouldn't write 1x where I wrote it, but just x instead, I just wrote 1x to make it easier to understand)
You have 1x medium wreaths to start with.
You have twice as many large wreaths as medium wreaths.
1x ⋅ 2 = 2x
So you have 1x medium wreaths and 2x large wreaths.
Lastly, it says you have 1/2 as many small wreaths as medium wreaths.
1x ⋅ 1/2 = 1/2x
So you have
1x + 2x + 1/2x = 3 1/2x wreaths, which is answer B.
