The lowest positive whole number that should replace the question mark on the pinner such that the probability of pinning an odd number greater than 6 is 1/4 is 9.
Lowest Odd NumberIt could be determined by calculating the probability of pinning an odd number greater than 6 out of the total number of possible outcomes.
If we consider the lowest positive whole number greater than 6 is 7, then we have 7,9,11,13,15,17,19,21,23,25 and so on.
Out of these numbers, 1/4 are odd numbers greater than 6. So the lowest whole number that could replace the question mark on the pinner is 9.
This is applicable for any situation where the probability of an event occurring out of a set of possible outcomes needs to be determined, and the lowest value for which that probability is a certain ratio needs to be found. In this case, the event is pinning an odd number greater than 6, and the set of possible outcomes is all positive whole numbers greater than 6. The probability being considered is 1/4, and the question is what is the lowest value that can replace the question mark on the pinner such that this probability is achieved.

The function g(x) repreent M(x) = 9 co (x - #) 3 after tranlating
I unit left and 4 unit up
Which equation repreent g(x)?
The equation for g(x) would be g(x) = 9cos(x-1) ^3 + 4.
This is because the function M(x) = 9cos(x)^3 represents a cosine function cubed, which results in a three-dimensional graph that oscillates and has multiple local maxima and minima. By translating the function one unit left, represented by the subtraction of 1 from the x value inside the cosine function, the entire graph is shifted one unit to the left.
The translation of 4 units up is represented by the addition of 4 to the overall function. This means that the entire graph of g(x) is now 4 units higher than the original function M(x).

You and your friend enter a drawing with 3 different prizes. A total of 15 people entered the drawing, and prizes are awarded randomly.
There are 2730 ways to award the prizes.
What is the probability that you win first prize and your friend wins second
prize?
A. 1/2730
B. 15/2730
C. 1/15
D. 13/2730
The probability that you win first prize and your friend wins second
prize is option D: 13/2730.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
Total number of prizes awarded = 3
Number of people entering the drawing competition = 15
Number of ways to award the prize = 2730
Out of the 3 prizes the first and the second is needed.
So, the prize for the first and the second positions are fixed and there is no need to consider the remaining 13 people to win the prize.
Hence the remaining number of people who can win the 3rd prize = 13
The number of ways one of them wins the 3rd prize = 13
The total number of ways = 2730
Therefore, the probability of the first 2 prizes fixed and the remaining 3rd awarded to the rest of the 13 people is 13/2730.

What system is Y =- 2x 3?.
The equation Y = -2x + 3 is a linear equation in slope-intercept form.
This equation represents a straight line with a slope of -2 and a y-intercept of 3.
The slope -2 tells us that for every unit increase in x, the value of y will decrease by 2. The y-intercept 3 tells us that the line passes through the point (0,3) on the coordinate plane.
It's a line that goes down as the slope is negative and the line can be represented by a graph, that can be easily plotted using the slope and the y-intercept. This equation can be used to model real-world situations like linear regression and many other fields.

Answer: Area = 28.3cm²
Circumference = 18.9cm
Step-by-step explanation:
Area = πr²
= π × 3²
= 28.27
= 28.3cm² (estimate to 3s.f always)
Circumference = 2πr
= 2 x π x 3
= 18.85
= 18.9cm (estimate to 3s.f always)
The area and the circumferences of the circle are 28.27 square meters and 18.85 meters.
Given is a circle with radius 3m we need to determine the area and the circumferences of the circle,
To determine the area and circumference of a circle with a radius of 3m, we can use the following formulas:
Area of a circle: A = πr²
Circumference of a circle: C = 2πr
Here, "r" represents the radius of the circle, and "π" (pi) is a mathematical constant approximately equal to 3.14159.
Let's calculate the values:
Area:
A = πr²
A = 3.14159 x (3m)²
A = 3.14159 x 9m²
A ≈ 28.27 square meters
Therefore, the area of the circle is approximately 28.27 square meters.
Circumference:
C = 2πr
C = 2 x 3.14159 x 3m
C ≈ 18.85 meters
Therefore, the circumference of the circle is approximately 18.85 meters.
Hence the area and the circumferences of the circle are 28.27 square meters and 18.85 meters.

Why is addition commutative and subtraction is not?.
Addition is commutative because the order in which two numbers are added does not affect the result.
Commutative property is applicable only for addition and multiplication processes. Thus, it means we can change the position or swap the numbers when adding or multiplying any two numbers.
Addition is commutative because the order in which two numbers are added does not affect the result. For example, 1 + 2 = 2 + 1 = 3. In contrast, subtraction is not commutative because the order in which two numbers are subtracted does affect the result. For example, 1 - 2 = -1, but 2 - 1 = 1. The operation is different when the order of the numbers are changed.
so, addition is commutative because the order in which two numbers are added does not affect the result.

4. Mariela purchases a used microwave for $50. She marks the price up 60%. If a 5.8% sales tax is also added, what is the final price of the microwave?
Mariela spends $50 on a used microwave. By 60%, she raises the price. When a 5.8% sales tax is additionally included, the ultimate cost is 20 in 60% and 47.1 in 5.8%.
How do you mark up 60%?Cost plus markup % multiplied by cost is the formula used to increase a product's markup percentage. Let's say you're utilising a markup of 60% and the item costs $75. multiplying by 60 percent $75. Now you have $45. For instance, the markup percentage would be 50% if the cost to produce your product was $50 and the selling price was $75: ($75 - $50) / $50 =.50 × 100=50%.
0.6 is 60 hundredths of a unit, thus write it as 0.60. 60% is equal to 60 hundredths. The decimal point can alternatively be shifted two places to the right to find the % equivalent. As a result, the markup equation is now: markup = 100 × (revenue - cost) / cost. Last but not least, use revenue = cost + cost × markup / 100 to determine the selling price.

Van has 45 new baseball cards. He puts them in a binder that holds 9 cards on each page. How many pages dose he fill?
To find out how many pages Van fills with his new baseball cards, we need to divide the total number of cards by the number of cards that fit on each page.
He has 45 baseball cards and each page holds 9 cards.
So, we can divide 45 by 9.
45 / 9 = 5
Therefore, Van fills 5 pages with his new baseball cards.
It's worth noting that this method gives the number of full pages that are filled and if there are any remaining cards, we have to add one more page for the remaining cards.
