Answer:
see explanation
Step-by-step explanation:
Note the ratios between consecutive terms is constant, that is
- 220 ÷ 11 = 4400 ÷ - 220 = - 88000 ÷ 4400 = - 20
Thus to obtain the next term in the sequence multiply the previous term by - 20
Start with 11 and multiply by - 20
Answer:
The number of expected people at the concert is 8,500 people
Step-by-step explanation:
In this question, we are asked to determine the expected number of people that will attend a concert if we are given the probabilities that it will rain and it will not rain.
We proceed as follows;
The probability that it will rain is 30% or 0:3
The probability that it will not rain would be 1 -0.3 = 0.7
Now, we proceed to calculate the number of people that will attend by multiplying the probabilities by the expected number of people when it rains and when it does not rain.
Mathematically this is;
Number of expected guests = (probability of not raining * number of expected guests when it does not rain) + (probability of raining * number of expected guests when it rains)
Let’s plug values;
Number of expected guests = (0.3 * 5,000) + (0.7 * 10,000) = 1,500 + 7,000 = 8,500 people
the operation:
Gives a square number.
<h3>
How to get a perfect square?</h3>
A perfect square is the product of a number and itself.
As you can see in the example, 16 is a square number. Then let's try to get 16.
To get 16 we can use the difference:
20 - 4
So the first therm needs to be equal to 20, and the second equal to 4.
To write 20 in scientific notation we have:
To write 4 in in scientific notation:
Then the operation:
Gives a square number.

16 meters
explanation:
8+8(since there’s two sides) =16
48-16=32
32/2= 16
so, each longer side is 16 meters
