if a college instructor alters the distribution of his or her students' midterm exam grades because the class did not do as well as last year's class, with what type of standards is the instructor most concerned?
The college instructor is most concerned with equity standards.
Equity standards are when an instructor adjusts grades to ensure fairness to all students regardless of their individual performances.
This means that if a class as a whole does not do as well as last year, the instructor will alter the distribution of grades so that the overall grades reflect the effort put in by the class.
For example, if the class average is a C, the instructor may raise some grades to a B or even A in order to ensure that the grades are fair to all students in the class.

The anglers club requires that member spend at least $250 per month at the restaurant Mr. Donovan has spent a $179.85 so far this month written inequality to describe situation
Answer: x + 179.85 ≥ 250
Step-by-step explanation:
x = the amount of money Mr. D has to spend to meet the monthly requirement.
since we know he already spent $179.85 this month we would have to add that money to x to find how much left he needs to spend to get up 250.
(we use the greater than or equal to sign because it says at least )
therefore, we would do the inverse of 179.85 which is subtracting 179.85, we do the same with 250 so x = 70.15
hope this helped :)
The Inequality is x + 179.85 ≥ 250.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
The anglers club requires that member spend at least $250 per month.
Mr. Donovan has spent a $179.85 so far this month.
let x be the amount of money Mr. Donovan has to spend.
As, he already spent $179.85 this month.
x= 250- 179.85
x= 70.15
Hence, the Inequality is x + 179.85 ≥ 250.

Answer:
Step-by-step explanation:
Suppose you hire an electrician to install several electrical outlets in your home. The electrician
charges $68.00 for materials plus $40.00 per hour for labor.
How much will the electrician charge you if the job take 2 hours?
Answer:
$148.00
Step-by-step explanation:
y is the total amount of money the electrician will charge.
x is the hours they work
$68 is the materials cost
y = $68 + 40(x)
It should all equal y since y is the total cost for the electricians service. You plug in 2 in place of x since it took them 2 hours.
y = 68 + 40(2)
y = 68 + 80
y = 148

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Write an equation that could be used to find the length of the parallelogram. (Remember: the perimeter of a rectangle is the sum of the lengths of its sides or P=2L + 2W)
Answer:
L= 16 m
W= 12 m
Step-by-step explanation:
let us define the parameters of the parallelogram
let the length be L
and the width be W
given that the W= L-4
perimeter= 72 meters
We know that the perimeter of a parallelogram is given as
\(P=2L + 2W\)
Substituting W= L-4 for W we have
\(72=2L + 2(L-4)\\\\72= 2L+2L-8 \\\\72= 4L-8\\\\4L= 72-8\\\\4L= 64\)
Divide both sides by 4 we have
\(L= 64/4\\\\L= 16 m\)
From w= L-4 we can find w by setting L= 16
W= 16-4
W= 12 m

I HAVE 30 MINUTES PLEASE T-T (I'll give 50 points) 1. Sally has a jewelry business. To make a certain necklace, she spends $2.51 on materials and $4.38 on labor. She then sells the necklace for $17.99. Lucy’s profit on the necklace is equal to the sale price minus the cost of materials and labor. (a) How much profit does Sally earn when she sells a necklace? $11.10 (b) What fraction of the sale price of the necklace is profit? (c) What decimal of every dollar of the sale price of the necklace is profit? Round your answer to the nearest hundredth. (d) Sally collected $269.85 selling necklaces at a craft fair. How many necklaces did Lucy sell? (e) How much profit did she earn?
Answer:
a. $11.10
b. 1 689/1110
c. 1.62
d. 15 necklaces
e. $166.50
Step-by-step explanation:
Materials = $2.51
Labor = $4.38
Cost of production = $2.51 + $4.38
= $6.89
Sales price = $17.99
a. Profits = sales price - cost of production
= $17.99 - $6.89
= $11.10
Sally earn $11.10 when she sells a necklace
b. Sales price = $17.99
Profits = 11.10
Fraction of sale price that is profits = $17.99 / $11.10
Multiply both numerator and denominator by 100
= 1799/1110
= 1 689/1110
c. Sales price = $17.99
Profits = 11.10
Decimal of every dollar of the sale price of the necklace that is profit = $17.99 / $11.10
= 1.6207
Approximately 1.62
d. Total selling price of necklace = $269.85
Selling price of each necklace = $17.99
Number of necklace sold = Total selling price of necklace / Selling price of each necklace
= $269.85 / $17.99
= 15 necklaces
(e)
Profits earned per necklace = $11.10
Total profits earned = Profits earned per necklace × Number of necklace sold
= $11.10 × 15
= $166.50

Answer:Range
Step-by-step explanation:the set of all images of the elements in the domain of a function is called the Range .
The set of all images of the elements in the domain of a function is called the range. The range is the set of all possible outputs or y-values that a function can produce for its corresponding inputs or x-values in the domain.
The range can be determined by either analyzing the function algebraically or by graphing it. It is important to note that not all functions have a defined range, as some may produce infinite or undefined outputs. The range plays a crucial role in understanding the behavior and characteristics of a function, as it helps identify its domain and any possible restrictions or limitations.
The set of all images of the elements in the domain of a function is called the range of the function. The range represents the output values of a function that result from applying the function to every element within its domain. In other words, the range consists of all possible values that the function can produce when it is applied to the elements in its domain.

what unit of measurement ios used to describe how far a sert of values are from the mean
standard deviation is the measure used to determine how values are from the mean
Standardizing a value occurs by determining the difference between the value and the mean, divide by the standard deviation
Multiplying or dividing all values will have the same affect on the mean since all values are changing equally.
The unit of measurement used is A. Standard deviation is the unit of measurement used to describe how far a set of values are from the mean.
What is standard deviation ?The degree of variation of data from the average, or mean, is gauged by the standard deviation. It provides us with information on the average amount by which each data point diverges from the mean.
A lesser standard deviation suggests that the data points gather closely around the mean, whereas a greater standard deviation signifies that the data points are further dispersed. To standardize a value, we subtract the mean from the value and then divide by the standard deviation.

The solution to the system of equation is as follows:
x = 4y = -2How to solve system of equation?System of equation can be solved with different methods such as elimination method, substitution method and graphical method.
The system of equation can be solved with elimination as follows:
Hence,
-3y + 5x = 26
-2y - 5x = -16
add the equation to eliminate x
Hence,
-5y = 10
divide both sides of the equation by -5
y = 10 / -5
y = -2
Hence,
- 3(-2) + 5x = 26
6 + 5x = 26
5x = 26 - 6
5x = 20
x = 20 / 5
x = 4

suppose 82% of all students at a large university own a computer. if 6 students are selected independently of each other, what is the probability that exactly 4 of them owns a computer?
The probability that exactly 4 out of 6 selected students own a computer is approximately 0.3493, or 34.93%.
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 how probable an event is to happen, or its chance of happening.
To calculate the probability of exactly 4 out of 6 selected students owning a computer, we can use the binomial probability formula:
\(P(X = k) = C(n, k) * p^k * (1 - p)^{(n - k)\),
where:
- P(X = k) is the probability of exactly k successes (4 students owning a computer),
- C(n, k) is the number of combinations of selecting k items from a set of n items (also known as the binomial coefficient),
- p is the probability of success (the proportion of students owning a computer), and
- n is the total number of trials (number of students selected).
In this case, n = 6, k = 4, and p = 0.82.
Using the formula, we can calculate the probability:
\(P(X = 4) = C(6, 4) * 0.82^4 * (1 - 0.82)^{(6 - 4)\),
C(6, 4) = 6! / (4! * (6-4)!) = 15,
\(P(X = 4) = 15 * 0.82^4 * 0.18^2\),
P(X = 4) ≈ 0.3493.
Therefore, the probability that exactly 4 out of 6 selected students own a computer is approximately 0.3493, or 34.93%.
