Answer:
6
Step-by-step explanation:
We need to evaluate :-
Here the
is the sum operator . And here we need to find the sum from n = 1 to n = 4 . We can write it as ,
Now we know that for odd powers of -1 , we get -1 and for even powers we get 1 . Therefore ,
Now add the terms inside the brackets and then multiply it with the number outside the bracket . We will get ,
<u>Hence</u><u> the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>6</u><u>.</u>
Collecting pennies can either be a dependent or an independent events based on the scenario.
<h3>How to illustrate the information?</h3>
Events classified as independent do not depend on other events for their occurrence. For instance, if we toss a coin in the air and it lands on head, we can toss it again and this time it will land on tail.
A coin toss is an illustration of an autonomous occurrence. With each toss of the coin, there is an equal probability (0.5) of either heads or tails occurring, presuming that the coin is fair and can only land on heads or tails. It doesn't matter if the coin came up heads on the prior toss.
In conclusion, collecting pennies can either be a dependent or an independent events based on the scenario.

ATO,
We should convert 1.18 minutes into seconds
1 minute = 60 seconds
60 + 18 seconds = 78 seconds
We should divide with the days
So,
78 seconds ÷ 39 days = 2 seconds per day.
So,it lose 2 seconds per day.

Answer:
3x=9.5, you would divide 3 on each side to get x by itself, so (3x)/3=9.5/3, which would lead to be x=9.5/3 or x= 3 and 1/6th, 3 + 1/6
Step-by-step explanation:
6a² + 7ax - 3x²
6a² + 9ax - 2ax - 3x²
3a(2a) + 3a(3x) - x(2a) - x(3x)
3a(2a + 3x) - x(2a + 3x)
(3a - x)(2a + 3x)
