The total interest earned is 40.75 and the final balance is 65.75
<u>Solution:</u>
Given, principle amount P = 25
Interest rate 
Times compounded per year n = 12
Time in years t = 30
On substituting the values we get
![A = 25 [ 1+ \frac{0.0325}{12}]^{12\times30}= 25 [2.63]= 65.75](https://tex.z-dn.net/?f=A%20%3D%2025%20%5B%201%2B%20%5Cfrac%7B0.0325%7D%7B12%7D%5D%5E%7B12%5Ctimes30%7D%3D%2025%20%5B2.63%5D%3D%2065.75)
Interest I = A - P [since, A = P+I]
3,4,6,3,2,5,6,1,12,8,3,2 calculate the mean
Bas_tet [7]
The mean is the average.
Add all the numbers together than divide by the amount of numbers there are:
3 + 4 + 6 +3 + 2 + 5 + 6 + 1 + 12 + 8 + 3 + 2 = 55
there are 12 numbers.
Mean = 55 / 12 = 4.583
Round the answer as needed.
In the standard deck of cards there are 52 cards, 26 red and 26 black.
The first event, random drawing of a red card (event A), has a sample space of an entire deck with 52 different elementary events occurring with equal probabilities of
1/52 . Out of them only 26 events are "good" (that is, the card we randomly pick is red). Therefore, the probability of picking a red card equals to P(A) = 26/52 = 1/2
The second event, random drawing of a black card from a deck of only 51 remaining cards (event B), is dependent on the results of the first event. If the first event (event A) occurs (red card is drawn), the deck for the second drawing contains 25 red and 26 black cards and the conditional probability of picking black card is P(B ∣ A) = 26/51.
Now we can use the concept of conditional probability and a formula that describes the probability of a combined event through the probability of one and conditional probability of another: P(A ⋅ B ) = P( A) ⋅ P(B ∣ A)
In our case P(A) = 1/2 and P(B ∣ A) = 26/51
Therefore, P(A ⋅ B) = (1/2) ⋅ (26/51) = 13/51
Given that a bag of fertilizer covers an area of 2000 ft^2, the number of bags required to cover a lawn whose dimensions is 360 ft by 120 ft will be given by:
Number of bags=(area of lawn)/(area covered by 1 bag)×(number of bags)
thus
area of lawn:
A=length*width
A=360×120=43,200 ft²
Area covered by 1 bag=2000 ft²
Number of bags required for the lawn:
43200/2000
=21.6 bags
~22 bags
