Step-by-step explanation:
Xavier needs to sell 12 painting to break even.
For a normal distribution <em>only, </em>for a population, not for particular sample.
proportion between 1 standard deviation, independent of μ and σ , is given by:
P(Z<1)-P(Z<-1)
=0.841345-0.158655=0.682689
=0.68 (to two places of decimal)
proportion between 2 standard deviations, independent of μ and σ , is given by:
P(Z<2)-P(Z<-2)
=0.977250-0.022750=0.954500=0.95 (to two places of decimal)
Answer is 2x^+3x-3 with reminder 4
Answer:
<em>It took 31 days for the patch to cover half the lake</em>
<em></em>
Step-by-step explanation:
The patch grows to double its size everyday
the patch completely covers the lake in 32 days
Since the patch doubles itself everyday, this means that the previous day before the 32nd day, the lake was just half covered.
Therefore, the the patch covered half the lake on the 31st day, i.e <em>it took 31 days for the patch to cover half the lake</em>
<em></em>
