Answer: The balance when Emma turns 18 = $ 48,132.38
Step-by-step explanation:
When interest is compounded quarterly, the accumulated amount after t years will be :
, where P = principal, r= rate of interest( in decimal)
Given: P= $ 20,000 , r= 5% =0.05
t = 18 years
The balance when Emma turns 18 = $ 48,132.38
Answer:
Step-by-step explanation:
Split these into two separate squares.
One has side lengths of x + 3, and the other has side lengths of x + 1.
<u>We'll solve the first square first.</u>
Here is the expression we want to use:
*
Use FOIL (first, outer, inner, last).
Simplify.
<u>Time for the second square!</u>
This goes similarly to the first one, so I'll omit any words and you can follow along with the math.
*
<u>Now, we'll add them together.</u>
Combine like terms.
And we're done!
Answer:
Probability of 100 managers being selected= 100C100*1100C800/1200C900
Probability of selecting just one manager = 1C100*1199C899/1200C900
Explanation:
Given 100 managers, 200 factory workers, 900 miscellaneous workers, and workers bring transferred 900
To find probability of 100 managers leaving given that probability = number of favorable outcomes/total number of outcomes
We use combination since order doesn't matter:
Combination formula= n!/r!(n-r)! Where n= total number of outcomes and r is number of outcome at one time and ! is factorial
Probability of 100 managers using nCr formula for each item = 100C100*1100C800/1200C900
Probability of 1 manager also applying nCr formula as above =1C100*1199C899/1200C900
8/10 is larger
I hope this helps!
You do this 35*x=21. and x is the percent. x=0.6. 0.6 is 60 percent. So 21 is 60 percent less than 35.
