You decide that you are going to flip a coin, and a six sided die.
What is the probability of the following events?
Tails and an even number? (Round to two decimal places)
Tails and the number 9?
Heads or a number bigger than 4? (Round to two decimal places)
Heads or the number 2? (Round to two decimal places)
Answers
Probability helps us to know the chances of an event occurring. The probability of getting a tail and an even number is 0.25.
What is Probability?
Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Since a coin has two faces, therefore, the probability of getting either of the sides of the coin is (1/2). While a die has six faces, so the probability of getting any side of the die is (1/6).
A.) The probability of getting a tail and an even number can be written as,
[tex]\text{Probability of getting a tail} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of Even Number(2,4,6) } = \dfrac{3}{6} = \dfrac{1}{2}[/tex]
[tex]\text{Probability (Tails and an even number)} = \dfrac12 \times \dfrac12 = 0.25[/tex]
B.) The Probability of getting tails and the number 9 can be written as,
[tex]\text{Probability of getting a tail} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of Number 9} = \dfrac{0}{6} = 0[/tex]
[tex]\text{Probability of the tails and the number 9} = 0[/tex]
C.) The Probability of getting Heads or a number bigger than 4 can be written as,
[tex]\text{Probability of getting a Head} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of a number bigger than 4 (5,6) } = \dfrac{2}{6} = \dfrac{1}{3}[/tex]
[tex]\text{Probability (Heads or a number bigger than 4 )} = \dfrac12 + \dfrac13 = \dfrac{5}{6} = 0.83333[/tex]
D.) The Probability of getting Heads or the number 2 can be written as,
[tex]\text{Probability of getting a Head} = \dfrac{1}{2}[/tex]
[tex]\text{Probability of the number 2} = \dfrac{1}{6}[/tex]
[tex]\text{Probability (Heads or the number 2 )} = \dfrac12 + \dfrac16 = \dfrac{8}{12} = 0.6666[/tex]

The net below shows a square pyramid. What is the lateral surface area?
A. 176 in^2
B. 112 in^2
C. 64 in^2
D. 210 in^2
Answers
Answer: B
Step-by-step explanation:
1/2 8 *7 = 28
because there is 4 triangles you do this 28+28+28+28
28+28+28+28 = 112
The lateral surface area of the pyramid is 112 sq. in.
The correct answer is an option (B)
From the attached figure of the net of a square pyramid, we can observe that the side length of the square base is 8 in and height of the lateral triangular face is 7 in.
Hence, The lateral surface area of the pyramid is equal to the area of the four triangular faces of the pyramid.
Using the formula of the area of triangle, the lateral surface area would be,
A = 4 × (1/2 × base × height)
A = 4 × (1/2 × 8 × 7)
A = 4 × (4 × 7)
A = 4 × 28
A = 112 sq. in.
Thus, This is the required lateral surface area.
So, The correct answer is an option (B) 112 in²

Brian invests £990 into his bank account. He receives 2.6% per year simple interest. How much will Brian have after 3 years? Give your answer to the nearest penny where appropriate
Answers
Answer:
£1067.22.
Step-by-step explanation:
Interest I= PRT/100 where P = Initial investment, R = % rate, T = time.
So I = 990*2.6* 3 / 100
= £77.22
So total he will have in the bank

We have two equations :
-5x - y = 5x = 7y - 1Take the value of x in Equation 2 and substitute in Equation 1.
-5(7y - 1) - y = 5-35y + 5 - y = 5-36y = 0y = 0Now, take the value of y and substitute in Equation 2.

-36y + 5 = 5 combine like terms
-36y = 0 subtract 5

Solve the following inequality, if it is known that function f is increasing on its domain. f(4x-3)[tex]\geq[/tex]f(2-[tex]x^{2}[/tex]), D_f = (-8, 4)
Answers
This solution is arrived at using the principles of Quadratic Functions and Inequalities. It is to be noted that the function increases at (-8, 4).
What are Quadratic Functions?A quadratic function can be defined as that is written in the following way: f(x) = ax2 + bx + c: Where a, b, and c are numbers not equal to zero.
How do we solve the problem above?To solve the problem f(4x - 3) ≥ f(2 - x^2), Df = (-8 , 4), we:
A) 4x - 3 ≥ 2 - x²
Rewrite as: x² + 4x - 2 - 3 ≥ 0
B) Collect the like terms
x² + 4x - 5 ≥ 0
C) Expand to have x² + 5x - x - 5 ≥ 0
D) Factorizing the expression we have
x(x + 5) - 1(x + 5) ≥ 0, from this we Factor away x + 5
(x - 1)(x + 5) ≥ 0
E) Solving for x we obtain: x ≥ 1 or x ≥ -5
This can also be rewritten to read:
-5 ≤ x ≤ 1

Answer:
x =number of child tickets
y=number of adult tickets
x + y = 9
3x +9y = 57
x = 9-y
3(9-y) + 9y =57
27 - 3y + 9y = 57
