Isabella earns interest at an annual rate of 10% compounded annually on her savings account. She deposits $2,000 into her accoun
IrinaK [193]

Answer:

10% of 2,000 is 200. 2000 + 200 = 2200. 10% of 2200 is 220. 2200 + 220 = 2420. Answer is 2420.

Step-by-step explanation:

She starts off with 2000. She earns 10% of 2000 the first year. 10% of 2000 is 200. Then add to get the amount of money she has at the end of that year. 2000 + 200 = 2200. Then the next year she earns 10% of 2200. 10% of 2200 is 220. Add 2200 + 220. 2200 + 220 = 2420.

Suppose that prices of recently sold homes in one neighborhood have a mean of $225,000 with a standard deviation of $6700. Using
elena55 [62]

Answer:

211600 = 225000 -k*6700

k = \frac{225000-211600}{6700}= 2

238400 = 225000 +k*6700

k = \frac{238400-225000}{6700}= 2

So then the % expected would be:

1- \frac{1}{2^2}= 1- 0.25 =0.75

So then the answer would be 75%

Step-by-step explanation:

For this case we have the following info given:

\mu = 225000 represent the true mean

\sigma =6700 represent the true deviation

And for this case we want to find the minimum percentage of sold homes between $211,600 and $238,400.

From the chebysev theorem we know that we have 1 -\frac{1}{k^2} % of values within \mu \pm k\sigma if we use this formula and the limit given we have:

211600 = 225000 -k*6700

k = \frac{225000-211600}{6700}= 2

238400 = 225000 +k*6700

k = \frac{238400-225000}{6700}= 2

So then the % expected would be:

1- \frac{1}{2^2}= 1- 0.25 =0.75

So then the answer would be 75%
