If a number is a square root of an integer, then it is irrational.
Answer:
Step-by-step explanation:
The square root of an integer is either an irrational number or an integer. The latter is the case if and only if there is an integer which, when multiplied by itself, or squared, yields the number inside the symbol (the radicand) as the product. All square roots except perfect squares are irrational numbers. 3 is not a perfect square.
for how many different digits n is the 3 digit number 14n divisible by n, 14n refers to a three digit number with the unit digit of n
0, 1, 2, 4, 5, and 7.
So that would be 6 digits.
In mathematics, the only single symbol used to represent a number is a digit. For instance, there are two digits in the numbers 89: 8 and 9. As a result, in everyday life, digits like 0, 1, 2, 3, 4, 5, 6, 7, 8, and 0 are employed to represent groups of numbers and perform mathematical operations. A positional numeral system uses a single sign, such as "2," or a set of symbols, such as "25," to represent numbers. The word "digit" derives from the fact that the ten fingers of the hands, or digit in Latin, corresponding to the ten symbols of the decimal system, which uses the base-10 numeral system.

all employees surveyed said that if they were in a state of information underload, they were dissatisfied.
Nearly 80% of those surveyed said they want to work for a company that values diversity, equity, and inclusion issues.
What is equity?
Value is utilized as capital raised by an organization, which is then used to buy resources, put resources into ventures, and asset tasks. A firm commonly can raise capital by giving obligation (as a credit or through bonds) or value (by selling stock). In finance, value is responsibility for that might have obligations or different liabilities joined to them. Value is estimated for the purpose of bookkeeping by taking away liabilities from the worth of the resources. For instance, on the off chance that somebody possesses a vehicle worth $24,000 and owes $10,000 on the credit used to purchase the vehicle, the distinction of $14,000 is value. Value can apply to a solitary resource, like a vehicle or house, or to a whole business. A business that requirements to fire up or grow its tasks can offer its value to raise cash that doesn't need to be reimbursed on a set timetable.

The two numbers by setting up a linear equation are 32 and 56 respectively
Linear function and equationA linear equation is an equation that has a linear degree of 1. Let the 2 unknown number be x and y
If the sum of two numbers is 88, then;
x + y = 88
If one number is 4 more than half the other number, then
x = 1/2y + 4
Substitute equation 2 into 1
x + y = 88
(1/2y+4) + y = 88
1/2y+y + 4 -88 = 0
3/2y - 84 = 0
3/2y. = 84
3y = 2(84)
3y = 168
y = 56
Determine the value of x
x =88 - 56
x = 32
Hence the two numbers by setting up a linear equation are 32 and 56 respectively

the population standard deviation for the height of college baseball players is 3.0 inches. if we want to estimate 95% confidence interval for the population mean height of these players with a 0.68 margin of error, how many randomly selected players must be surveyed?
The number of players randomly selected is 381 and the standard deviation is 1.96.
What is the standard deviation?The standard deviation is a measurement of how much a group of values varies or is dispersed. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection. The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation. Standard deviation may be written as SD. A random variable, sample, statistical population, data set, or probability distribution's standard deviation is equal to the square root of its variance.
[tex]Z(\alpha /2)=1.96[/tex]
Sample size = n = [tex][Z(\alpha /2 * \sigma/E) ]^{2}[/tex]
n = [1.96 * 3.0 / 0.95]²

What is the general solution of a trigonometric equation?The general solution of a trigonometric equation is a formula employing the integer n that provides all solutions.
Given:
EQuation: 2 cos( 4θ) - 1 = 0.Interval: 0 ≤ θ ≤ π/2TO find: Values of θ.
Finding:
In the given equation: 2 cos( 4θ) - 1 = 0,
=> cos (4θ) = 1/2
=> cos (4θ) = cos (π/3)
=> 4θ = 2nπ ± π/3
=> θ = nπ/2 ± π/12
For n = 0, θ = ± π/12
For n = 1, θ = π/2 ± π/12
Since θ ∈ [0, π/2], the possible values of θ = π/12, π/2 - π/12 = 5π/12.
