Complete the sentences:
Answer:
a) "impossible event"
b) "certain event"
c) Letter A.
Step-by-step explanation:
a) An event with probability 0 is said to be:
These events are called "impossible events" (but there are more complex cases where we can have probabilities 0, and the events are not necessarily impossible events)
b) An event with probability 1 is said to be
An event with a probability of 1 is an event that will happen, these events are called "certain event"
c) The probability for each outcome of an unbiased experiment of N different outcomes will be 1/N
for example, for a 6-side dice we have 6 outcomes, then the probability of each outcome is 1/6.
For the coin, we have 2 outcomes, then the probability of each outcome is 1/2
Probability of getting a head = 1/2 = 0.5
In the image, we can see that letter A is on the 0.5 value, then the correct answer here is A.

How to calculate the surface area of a composite figure?Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
We are given that;
The side of two hexagon is 2ft, painting measures 9*25ft.
Now,
In this case, s = 2 feet. Therefore, the area of one hexagonal window is:
Area = (3√3 × 2²)/2 Area = (12√3)/2 Area ≈ 10.39 square feet
Since there are two windows, we need to multiply this by 2 and subtract it from the total area of the wall:
225 - (2 × 10.39) ≈ 204.22 square feet
This is the area that needs to be painted. To find how much Deb will have to spend, we multiply this by $1.75 per square foot:
204.22 × $1.75 ≈ $357.39
Rounding this to the nearest dollar, we get:
$357
Therefore, by the area of painting the answer will be $357.

Polynomial Operations 1&2 Test 10 of 1610 of 16 Items Item 10 The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
Answer:
3x + 2
Step-by-step explanation:
The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
The shape of a poster = Rectangular shape
Hence:
The Perimeter of a Rectangle (Poster) = 2L + 2W
Where:
Length = Height = 7x + 10
Perimeter = 20x + 24
Therefore:
20x + 24 = 2(7x + 10) + 2W
20x + 24 = 14x + 20 + 2W
2W = 20x + 24 - (14x + 20)
2W = 20x + 24 -14x - 20
2W = 6x + 4
W = (6x + 4)/2
W = 3x + 2
Therefore, the width of the poster
= 3x + 2

Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k

4. What is the volume of the cone shown below?
Round to the nearest tenth.
5 ft.
d = 2 ft.
Answer:
5.2 cubic ft
Step-by-step explanation:
took the test
The volume of given cone is 5.23 cubic feet.
What is volume?Volume is the measure of the capacity that an object holds.
Formula for the volume of cone[tex]v = \frac{1}{3} \pi r^{2} h[/tex]
where,
v is the volume of cone
r is the radius of cone
h is the height of cone
According to the question we have
Diameter of cone is 2ft
⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]
Height of the cone is 5ft.
Therefore,
The volume of the cone = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]
Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]
Hence, hence the volume of given cone is 5.23 cubic feet.

Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24

Collin Buys a TV for £720 depreciate at a rate of 4% per year how much will it be worth in three years
Answer:
The worth of the TV after 3 years is £809.90208
Step-by-step explanation:
The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine
The given parameters of the TV are;
The amount at which Collin buys the TV, P = £720
The rate at which the TV depreciates at, R = 4%
The number of years the depreciation is applied, T = 3 years
The amount the TV is worth after three years, 'A', is given as follows;
[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]
By plugging in the known values, we have;
[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]
The amount the TV is worth after three years, A = £809.90208
