Answer:
D. 8
Step-by-step explanation:
We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.
As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.
So we can set an equation as:
or
Therefore, the standard deviation for our given data is 8 and option D is the correct choice.
Answer:
429
Step-by-step explanation:
312/800 = .39
1100 x .39 = 429
Okay so your partner describes a situation that has a slope of NEGATIVE 5, not positive 5 as your teacher asked.
Instead, your younger brother could have started with 100 and GAINED 5 every month, instead of losing 5.
Well if your equation is 9=-2/3x-y, you’ll have to make it into y=Mx+b form first so subtract 9 from both sides and add y from both sides. your equation should be y=-2/3x-9. therefore you’re answer is 4.
