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

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 table shows the results of an experiment in which three coins were tossed.
What is the experimental probability that at least two of the coins will be heads? The theoretical probability?
The experimental probability that at least two heads would be gotten is 11 / 25.
The theoretical probability that at least two heads would be gotten is 1/2.
What are the probabilities?Probability calculates the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Experimental probability is based on the result of an experiment that has been carried out multiples times.
Experimental probability = number of times at least two heads would be gotten / total number of tosses
( 5 + 6 + 6 + 5)/50 = 22/50 = 11 / 25

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]
