A regulation baseball field measures 90 feet between each base. What is the distance around the bases in yards?
The distance around the bases in yards is 30 yards.
In order to determine the distance between each base in yards the unit of conversion of feet to yards have to be first determined. 1 foot is equivalent to 0.333333 yards.
1 feet = 0.333333 yards
The second step is to multiply the distance between each base by the unit of conversion.
Distance between each base x unit of conversion
90 x 0.333333
= 30 yards

The probability of a couple having at least one boy when they have two children is 75%, as three out of four possible outcomes include at least one boy. These outcomes are two boys, a boy then a girl, and a girl then a boy.
Explanation:The subject of the question is probability which is a branch of mathematics. In order to find the probability that when a couple has two children, at least one of them is a boy, we need to analyze possible outcomes. The couple could have two boys (BB), a boy and a girl (BG), a girl and a boy (GB), or two girls (GG). Hence, the total unique outcomes are 4 (BB, BG, GB, GG).
Considering at least one boy, the possible outcomes could be BB, BG, GB, which are 3 possibilities. Finally, the probability is given as the ratio of favorable outcomes to the total number of outcomes. So the probability of having at least one boy is 3/4 or 75%.

At that rate, how many words can the programmer type in 11 min?

Answer:
605 words per 11 minutes!
Step-by-step explanation:
60 / 55 = 1.0909
11 x 60 = 660
660 / 1.0909 = 605 + (6x - [tex]\int\limits^a_c {b} \, dx[/tex]) / 10
605 + (6x - [tex]\int\limits^a_c {b} \, dx[/tex]) / 10 rounded = 605
What is the return value of "select".substring(4, 4)?
The expression "select".substring(4, 4) will return an empty string, as the start and end indices are the same and no characters are included in the specified range.
Explanation:The substring method in many programming languages, including Java and JavaScript, is used to extract a portion of a string between two specified indices. In the expression "select".substring(4, 4), we are asking for the part of the string starting at index 4 and up to, but not including, index 4. Since the start and end indices are the same, the method will return an empty string.
It's important to note that string indices are zero-based, meaning that the first character of the string is at index 0. The string "select" has six characters, with indices ranging from 0 to 5. Therefore, calling substring with identical start and end indices will not include any characters in the resulting string.
Example:To retrieve the first character of "select", you would use "select".substring(0, 1).To retrieve "lec" from "select", you would use "select".substring(1, 4).Mrs evans has 120 crayons and 30 pieces of paper to give to her students. what is the largest number of students she can have so that each student gets equal number of crayons and equal number of pieces of paper
The maximum number of students that will receive the paper and crayons are 30.
What is ratio?
Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Given is Mrs. Evans who has 120 crayons and 30 pieces of paper to give to her students.
We have 120 crayons and 30 pieces of paper.
Then for 1 paper, we will have (120/30) which is equivalent to 4 crayons.
So, every student will get 1 paper and 4 crayons.
Assume that the maximum number of students that will receive the paper and crayons are [x]. Then, we can write -
x + 4x = 120 + 30
5x = 150
5x = 150
x = 30
Therefore, the maximum number of students that will receive the paper and crayons are 30.

Find the exact coordinates of the centroid for the region bounded by the curves y=x, y=1/x, y=0, and x=2
The centroid of the region bounded by [tex]\(y=x\), \(y=\frac{1}{x}\), \(y=0\),[/tex] and [tex]\(x=2\)[/tex] is at [tex]\((\frac{2}{3}, 0)\).[/tex]
To find the centroid of the region bounded by the curves[tex]\(y=x\), \(y=\frac{1}{x}\), \(y=0\), and \(x=2\),[/tex]we need to first find the area of the region and then compute the coordinates of the centroid using the following formulas:
The centroid of a region with area[tex]\(A\)[/tex] is given by [tex]\((\bar{x}, \bar{y})\)[/tex]where
[tex]\[\bar{x} = \frac{1}{A} \int\int_R x \, dA\][/tex]
[tex]\[\bar{y} = \frac{1}{A} \int\int_R y \, dA\][/tex]
First, let's find the points of intersection for the curves:
1. [tex]\(y=x\) and \(y=1/x\):[/tex]
[tex]\[ x = \frac{1}{x} \implies x^2 = 1 \implies x = 1 \][/tex]
So, the intersection point is [tex]\((1,1)\).[/tex]
2. [tex]\(y=0\) and \(x=2\):[/tex]
This intersection occurs at [tex]\((2,0)\).[/tex]
Now, we'll integrate to find the area and then the centroid:
1. Area:
[tex]\[ A = \int_{0}^{1} (x - \frac{1}{x}) \, dx + \int_{1}^{2} (\frac{1}{x}) \, dx \][/tex]
[tex]\[ A = \left[\frac{x^2}{2} - \ln|x|\right]_{0}^{1} + \left[\ln|x|\right]_{1}^{2} \][/tex]
[tex]\[ A = \left(\frac{1}{2} - 0 - (0 - \infty)\right) + (\ln(2) - \ln(1)) \][/tex]
[tex]\[ A = \frac{1}{2} + \ln(2) \][/tex]
2. Centroid[tex](\(\bar{x}\)):[/tex]
[tex]\[ \bar{x} = \frac{1}{A} \left[\int_{0}^{1} x(x - \frac{1}{x}) \, dx + \int_{1}^{2} x(\frac{1}{x}) \, dx\right] \][/tex]
[tex]\[ \bar{x} = \frac{1}{A} \left[\left[\frac{x^3}{3} - \frac{1}{2}\ln|x|\right]_{0}^{1} + \left[\ln|x|\right]_{1}^{2}\right] \][/tex]
[tex]\[ \bar{x} = \frac{1}{A} \left(\frac{1}{3} - 0 - (0 - \infty) + (\ln(2) - \ln(1))\right) \][/tex]
[tex]\[ \bar{x} = \frac{\frac{1}{3} + \ln(2)}{\frac{1}{2} + \ln(2)} \][/tex]
[tex]\[ \bar{x} = \frac{2}{3} \][/tex]
3. Centroid [tex](\(\bar{y}\)):[/tex]
[tex]\[ \bar{y} = \frac{1}{A} \left[\int_{0}^{1} (x - \frac{1}{x}) \cdot 0 \, dx + \int_{1}^{2} (\frac{1}{x}) \cdot 0 \, dx\right] \][/tex]
[tex]\[ \bar{y} = 0 \][/tex]
Therefore, the centroid of the region is at the point [tex]\(\left(\frac{2}{3}, 0\right)\).[/tex]

describe the steps you would follow to write a two-step inequality you can use to solve a real-world problem.
Final answer:
To write a two-step inequality for a real-world problem, first identify the unknowns and known quantities related to the problem. Next, construct an inequality that represents the problem, and finally solve the inequality for the unknown variable. For example, budgeting for a party with a savings goal can be represented as an inequality.
Explanation:
To write a two-step inequality to solve a real-world problem, follow these steps:
Identify the unknowns: Understand what needs to be determined. This involves defining the variable(s) that will represent the unknown quantity(ies) in the problem.
Identify the known quantities: Make a list of the quantities that are given or can be inferred from the problem. These are the values you will use to construct your inequality.
Construct the inequality: Use the information from steps 1 and 2 to create an inequality that represents the problem. This often involves expressing the relationship between the known and unknown quantities using an inequality symbol (such as <, >, ≤, ≥).
Solve the inequality: Apply algebraic methods to solve for the unknown variable. This may involve isolating the variable on one side of the inequality.
For example, if you are planning a party and know you have a budget of $200 for decorations but want to save at least $50, you could set up the inequality x + 50 ≤ 200, where x represents the amount you can spend on decorations.
