What is the probability of getting two heads if you flip two fair coins? answer as a simplified fraction
Answer: [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
use probability
the chances of you getting heads on a coin is 50% therefore, flipping two coins is just
[tex]\frac{1}{2} * \frac{1}{2}= \frac{1}{4}[/tex]
Answer:
the probability of getting two heads is 1/4
Step-by-step explanation:
H = (HH) => n(H) = 1
n(S) = 4
P(E) = number of favourable outcomes/total number of outcomes = n(E) / n (S)
PH = n(H)/n(S)
= 1/4

How many 5-digit numbers are there, that are "even"? Show all work/ calculations.
Answer: The correct answer is 13776.
Explanation: There are 3024 five-digit numbers that begin with the digit 4 with no repetition.
Must show work-Solve the conjunction and describe the solution set. −5 < 2x + 3 < 9
The solution set of the inequality −5 < 2x + 3 < 9 is (-4,3)
How to solve the inequality?The compound inequality is given as:
−5 < 2x + 3 < 9
Expand the inequality
−5 < 2x + 3 or 2x + 3 < 9
Rewrite as:
2x + 3 > -5 or 2x + 3 < 9
Subtract 3 from both sides
2x > -8 or 2x < 6
Divide both sides by 2
x > -4 or x < 3
Rewrite as:
(-4,3)
Hence, the solution set of the inequality is (-4,3)

Which phrase represents the algebraic expression 7p-9?
Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine
A composite figure is shown.
Diagram shows a composite shape formed by placing a cube before a square prism and a square pyramid next to it that share a common square base. Cube has sides labeled 6 feet. Length of the square prism is 20 feet and height of the pyramid is 4 feet.
What is the surface area for each part of the figure? What is the total surface area of the figure?
The surface area of the pyramid is
square feet.
The surface area of the square prism is
square feet.
The surface area of the cube is
square feet.
The total surface area is
square feet.
The surface area of the pyramid is 60 square feet
The surface area of the square prism is 480 square feet
The surface area of the cube is 180 square feet
The total surface area is 720 square feet
Area of Composite figuresFrom the question, we are to calculate the surface area of each part of the composite figure
For the cubeSurface area of a cube is given by
[tex]S = 6l^{2}[/tex]
Where [tex]l[/tex] is the length of a side
But only have 5 surfaces of the cube are part of the composite figure
∴ Surface area of the cubic part of the figure = [tex]5l^{2}[/tex]
From the given information,
[tex]l = 6 \ feet[/tex]
∴ Surface area of the cubic part of the figure = 5 × 6²
Surface area of the cubic part of the figure= 180 square feet
For the square prismThe surface area of a square prism is given by the formula,
[tex]S = 2l^{2} + 4lh[/tex]
Where [tex]l[/tex] is the length of the sides and
[tex]h[/tex] is the height
But the square surfaces are not part of the surface of the figure
∴ Surface area of the square prism in the figure = [tex]2l^{2} + 4lh - 2l^{2}[/tex]
Surface area of the square prism in the figure = [tex]4lh[/tex]
From the given information,
[tex]l = 6 \ feet[/tex]
[tex]h = 20 \ feet[/tex]
Thus,
Surface area of the square prism part of the figure = 4×6×20
Surface area of the square prism part of the figure = 480 square feet
For the pyramid
The pyramid is a square pyramid
The surface area of a square pyramid is given by
[tex]S = l^{2} + 2l\sqrt{\frac{l^{2} }{4}+h ^{2} }[/tex]
Where [tex]l[/tex] is the base length
and [tex]h[/tex] is the height of the prism
But the square base is not part of the surface of the figure
∴ Surface area of the pyramid part of the figure = [tex]l^{2} + 2l\sqrt{\frac{l^{2} }{4}+h^{2} }\ - ( l^{2})[/tex]
Surface area of the pyramid part of the figure = [tex]2l\sqrt{\frac{l^{2} }{4}+h^{2} }[/tex]
From the given information,
[tex]l = 6 \ feet[/tex]
[tex]h = 4 \ feet[/tex]
∴ Surface area of the pyramid part of the figure = [tex]2(6)\sqrt{\frac{6^{2} }{4}+4^{2} }[/tex]
= [tex]12\sqrt{\frac{36 }{4}+16}[/tex]
= [tex]12\sqrt{9+16 }[/tex]
= [tex]12\sqrt{25}[/tex]
= 12 × 5
= 60 square feet
Hence, the surface area of the pyramid is 60 square feet
Thus,
The total surface area = 180 square feet + 480 square feet + 60 square feet
The total surface area = 720 square feet
Hence, the total surface area is 720 square feet

What is completing the squares method for solving the quadratic method?Suppose the considered quadratic equation is of the form
ax^2 + bx + c = 0
Then, completing the squares method tries to make a squared term in terms of x in the left side, so that x comes in linear form, instead of quadratic.
The given quadratic equation is
x² + 7x = 4
add 7²/2 to both sides of x² + 7x = 4 to complete the square
7²/2 = 49/4
x² + 7x + 49/4 = 4+ 49/4
(x + 7/2)² = 4+ 49/4
Thus, option C 7²/2 is correct.
