Relative frequency is the absolute frequency (i.e. the number of times of the wanted result) divided by the total number of events.
In this case you have to calculate: the number of heads that came up divided by the number of times the coin was flipped.
Number of times the coin was flipped: 20
Numbef of times head came up: 7
Relative frequency: 7 / 20 = 0.35, which is the option B.
Answer:
The set of coefficients asociated with the given polynomial in ascending order is .
Step-by-step explanation:
Let , which is a polynomic function, defined as:
(1)
Where:
- i-th Coefficient.
- i-th Power.
- Grade of the polynomial.
We notice that given polynomial has degree 2 and can be rewritten by applying this definition:
Then, the set of coefficients asociated with the given polynomial in ascending order is:
<h3>
Answer: x = 3</h3>
To get that answer, we replace y with 8 and then isolate x.
5x-7 = y
5x-7 = 8
5x = 8+7
5x = 15
x = 15/5
x = 3
Answer:
cm²
Step-by-step explanation:
Surface area of the composite figure = Surface area of the lateral surfaces of the given pyramids
Lateral surface area of a square pyramid = 4
Therefore, lateral surface area of the pyramid
=
Now lateral surface area of the composite figure = 2(lateral surface area of two pyramids)
=
Therefore, Expression for the surface area of the given composite figure is,
cm²
