Find the amount in a bank account if you deposited $10,000 for 25 years at 6.25% interest compounded quarterly.
KengaRu [80]
Ok, so the formula for compound QUARTERLY is A=P(1+ʳ/n)ⁿ<span>ᵗ.
P= The initial amount.
R= The Rate
T= The Time/Number of Years
N= Number of time interest is compounded per year. (In this case its 4 because it compounded QUARTERLY.)

So if you input the numbers, you will get A=10,000(1+0.0625/4)</span>⁴⁽²⁵⁾<span>
Now solve inside the parenthesis.
10,0 00(1.0625/4)</span>⁴⁽²⁵⁾
Now you will need a calculator for the next part...
Do 1.0625/4 and times it by 10,000 .
You will get 0.0265265. You can't for get about the ⁴⁽²⁵⁾.
⁴⁽²⁵⁾=<span>¹⁰⁰
</span>2,656.25¹⁰⁰=

Nicoli jokic plays for the Denver nuggets in one game, his field-goal total was 26 points made up of 2 point and 3 point baskets
mel-nik [20]

9514 1404 393

Answer:

  • 4 3-point baskets
  • 7 2-point baskets

Step-by-step explanation:

Let x represent the number of 2-point baskets Nicoli made. Then (x -3) is the number of 3-point baskets. The total number of points is ...

  2x +3(x -3) = 5x -9 = 26

  5x = 35 . . . . . . add 9

  x = 7 . . . . . . . divide by 5

  (x -3) = 4 . . . find the number of 3-point baskets

Jokic made 7 2-point baskets and 4 3-point baskets.

Mickey keeps picking playing cards out of a standard deck of 52 cards, hoping that she will
andrew-mc [135]

Answer:

03%

Step-by-step explanation:

In this situation Mickey should have drew first 7 cards that are not diamond and then on the 8th attempt she should draw an ace.

Let A be the event of drawing 7 cards which are not diamond and B the event of drawing an ace card. therefore required probability is P(A∩B)=P(A)*P(B)

Now, there are 13 diamonds and 39 other cards. Hence,

P(A)=(\frac{39}{52})⁷=0.1335

After drawing 7 non-diamond cards, the 8th card must be a diamond.Hence,

P(B)=\frac{13}{52}=0.25

Hence, P(A∩B)=P(A)*P(B)=0.1335*0.25=0.033(approximately 0.03,i.e. 3%)

Therefore probability that Mickey will draw her first diamond on the 8th

attempt is 3%
