<span>To find the compound interest of an investment you have to use this formula, A = P(1 + r/n)^nt, where A is the total amount you have after the investment period, P is the amount you invest or the amount you put in, r is the rate of the of the compound interest in this case 10%, n is the amount of time the interest will be compounded for example, 4 months a year(quarterly) or 6 months a year(semi annually), and t is the amount of time you invest in years.
So in this case you are going to substitute everything in the formula with their given value. So P = $700, r = 10%, n = 21 (because it is the number of months we invest for), and t = 2 years (because 21 months fit perfectly in 2 years, and t must always be in years). The resulting formula will be A = $700(1 + 0.1/21)^(21 x 2), which will give you an answer of $855 rounded to the nearest dollar.</span>
There are 4 jacks in the deck.
13 are clubs and 26 are all red cards.
The computation for the following problems are shown below:
a.
All are jacks
Computation: 4/52 * 3/51 * 2/50 = 1/5525
b.
All are clubs
Computation: 13/52 * 12/51 * 11/50 = 11/850
c.
All are red card
Computation: 26/52 * 25/51 * 24/50 = 2/17
Answer:
The cause may be environmental
Explanation:
The ratios show that ratio of incidence of chronic lymphocytic leukemia (CLL) in the population of country X is five times higher than the ratio in U.S. whites. However, the ratio of CLL in migrants from Country X to the U. S. is exactly the same as the ratio in U.S. whites. This relationship indicates that, rather than being genetic, the cause of CLL is more likely to be environmental.
Answer:
The value of the test statistic is z= 2.40
Explanation:
n= 1100 (sample size)
