Answer:
Step-by-step explanation:
Let's first arrange it in ascending order :
340, 480, <u>560</u>, 680, 700
<u>560</u> is clearly the median.
Now add an additional score of 700 to the data :
340, 480, <u>560, 680</u>, 700 ,700
<u>560, 680</u> is separating both halves but is not the median
Median = (560+680)/2
= 1240 / 2
Median = 620
First we are going to reesribir the inaginario number:
i = root (-1)
i = (- 1) ^ (1/2)
Then, we have to
By properties of exponents:
i ^ 3 = i ^ 2 * i
Substituting the value of i:
i ^ 3 = ((- 1) ^ (1/2)) ^ 2 * i
Applying properties of exponents:
i ^ 3 = ((- 1) ^ (1/2)) * ((- 1) ^ (1/2)) * i
i ^ 3 = ((- 1) ^ ((1/2) + (1/2)) * i
i ^ 3 = ((- 1) ^ ((2/2)) * i
i ^ 3 = ((- 1) ^ (1) * i
i ^ 3 = -1 * i
i ^ 3 = - i
Answer:
D.-i
Assuming that the interest rate in each case is the same, the only factors that come into play are the length of time, and the accessibility of the money. The longer the money is left alone, the more money it will accrue, meaning the first option "saving for retirement in 20 years" is the best option. The two below it are a shorter length of time and will therefore accrue less, and the final option is less profitable because withdrawing from the account would decrease the total interest earned.
0.007 x 10 = 0.07
<span>In the scientific value of 5.893 x 10n. The standard value is 0.00005893 what is n? To better illustrate this phenomenon, we can explain it further under the rules of scientific notation. </span>
<span>For example. </span><span><span>
1. </span> 3 x 10^3 = 3 x 100 = 300</span>
<span><span>2. </span> 3 x 10^-3 = 3 x 0.001 = 0.003</span>
<span>Solution: </span>
<span>0.00005893 = 5.893 x 0.00001 = </span>5.893 x 10^-5
n= ^-5
