What is the probability of picking a blue? In a decimal
the probability of picking a blue is 0.45.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
3 red pens, 9 blue pens, 8 green pens
now, we get,
There are a total of 20 pens.
There are 9 blue pens out of 20 total pens.
In decimal format,
i.e. 9/20
=0.45
you have a chance of 0.45 .

A package of cookies contains 6 cookies. Each package of cookies costs $1.49.
A function, f(x), is written to represent the cost of purchasing x packages of cookies.
What is the practical domain for the function f(x)?
A: all positive integers
B: all real numbers
C: all whole numbers that are multiples of 6
D: all whole numbers
Given are 6 cookies in a package.
Given that the cost of a package = 1.49 dollars.
Let's assume we purchase 'x' numbers of packages.
So, total cost of 'x' packages = '1.49x' dollars.
f(x) is the function that represents the cost of 'x' packages, i.e. f(x) = 1.49x
Since the number of packages can not be negative or can't be decimal numbers, so 'x' should be positive integral values.
So, the practical domain of f(x) would be "positive integral values".
Hence, option A is correct, i.e. "all positive integers".
The median is 28; 16,24,x,48

Baby Kelsey wants to arrange 12 blocks in a row. How many different arrangements can she make?
To find the number of arrangements Baby Kelsey can make with 12 blocks, we calculate 12 factorial (12!), which equals 479,001,600. This represents the total number of unique ways to arrange the blocks in a row.
Explanation:The student has asked how many different arrangements can be made with 12 blocks in a row. To determine the number of different arrangements, we use the concept of factorial, which is represented by an exclamation mark (!). In this case, we want to find 12!, which represents the product of all positive integers from 1 to 12.
Specifically, the calculation is 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1. This multiplication results in the number of unique ways to arrange the 12 blocks since each block is distinct and can be placed in any position within the arrangement.
Therefore, there are 479,001,600 different arrangements possible when organizing 12 unique blocks in a row, showcasing the vast number of combinations for even a small number of objects.

Find the volume of a right prism with height h=10 cm, if: a The base is equilateral triangle with side 4 cm, base altitude of ≈ 3.5 cm. Help me!!!
To find its Volume of Right prism we multiply the base of the triangle times the height and divide that by 2.Then, multiply the area times the length, or the depth, of the prism to find the volume.
Area of the equilateral triangle = [tex]\frac{1}{2}x4x3.5.[/tex]
Area of triangle = 7 square cm.
Volume of the right prism = Area of triangle x Height of prism = 7x10 =70 cubic cm.
Volume of right prism = 70 cubic cm.

(Use a comma to separate answers as needed.)
To solve the equation (x + 4)(x - 9) = 4x, expand and rearrange the terms. Then solve the quadratic equation by factoring or using the quadratic formula.
Explanation:To solve the equation (x + 4)(x - 9) = 4x, we can expand the left side of the equation and then rearrange the terms:
x^2 - 5x - 36 = 4x
Next, we can move all the terms to one side of the equation:
x^2 - 9x - 36 = 0
Finally, we can solve this quadratic equation by factoring or using the quadratic formula to find the values of x.

A fish tank in the shape of a rectangular prism has these dimensions: length = 20 inches width = 10 inches height = 12 inches What is the volume of water in the tank when it is 45 full?
The volume of water in the fish tank when it is 45% full is 1080 cubic inches.
Explanation:To find the volume of water in the tank when it is 45% full, we first need to calculate the volume of the tank.
The formula for the volume of a rectangular prism is length × width × height.
Given that the length is 20 inches, the width is 10 inches, and the height is 12 inches, we can substitute these values into the formula: 20 × 10 × 12 = 2400 cubic inches.
Next, we need to find 45% of this volume. To do this, we multiply the volume by 0.45: 2400 × 0.45 = 1080 cubic inches.
Therefore, the volume of water in the tank when it is 45% full is 1080 cubic inches.
What is the input to a trigonometric function?
a ratio
the x position of a point on the circle
a central angle of a circle
the y position of a point on the circle
Answer: A central angle of a circle
Step-by-step explanation:
The trigonometric functions are also known as circular functions.
The two fundamental trigonometric functions are defined as the coordinates of a any point A travelling around on the unit circle of radius 1 .
The input variable in trigonometric functions is the central angle of the circle 'x' such that we get sin x and cos x which give the x and y coordinates of A.
Hence, the input to a trigonometric function is a central angle of a circle.

A) Wyatt should get the promotion. His data is more evenly distributed, so his sales are more consistent.
B) Wyatt should get the promotion because he had the highest sales in a single day.
C) Tammy should get the promotion because her lowest value is higher than Wyatt's lowest value.
D) Tammy should get the promotion. She has a higher median with a smaller IQR, so her sales are better on average.
Answer:
Tammy should get the promotion. She has a higher median with a smaller IQR, so her sales are better on average.

What is the exact area of a circle with a diameter of 20 cm?
400πcm^2
10πcm^2
100πcm^2
20πcm^2
The exact area of a circle with a diameter of 20 cm is 100π cm². This is found using the formula Area = πr², with 'r' being the radius of the circle.
Explanation:The subject of this question falls under the category of Mathematics, specifically geometry. In order to find the area of a circle, we use the formula: Area = πr², where r is the radius of the circle.
The diameter of the circle is given as 20 cm, so the radius, which is half the diameter, would be 10 cm. Substituting the radius value into the formula gives us: Area = π(10 cm)² = 100π cm². Therefore, the exact area of the circle with a diameter of 20 cm is 100π cm².

What is 40.15 divided by 7.3, written as a decimal?
Final answer:
To calculate 40.15 divided by 7.3, we can use long division. The final quotient is 5.5, and there is no remainder. Therefore, 40.15 divided by 7.3 written as a decimal is 5.5.
Explanation:
To calculate 40.15 divided by 7.3, we can use long division.
First, we write the division problem with 40.15 as the dividend and 7.3 as the divisor:
5.5
________
7.3 | 40.15
We start by dividing 40.15 by 7.3. The quotient is 5.5.
Next, we subtract 5.5 multiplied by 7.3 from 40.15:
5.5
________
7.3 | 40.15
- 36.5
________
37.65
Since the remainder, 37.65, is greater than the divisor, 7.3, we can continue dividing.
We bring down the next digit from the dividend, which is 0, and divide it by 7.3:
5.5
________
7.3 | 40.15
- 36.5
________
4.15
3.65
We repeat the process of dividing and subtracting until the remainder is less than the divisor:
5.5
________
7.3 | 40.15
- 36.5
________
4.15
3.65
5.5
0
The final quotient is 5.5, and there is no remainder. Therefore, 40.15 divided by 7.3 written as a decimal is 5.5.
