Rate of change of y = [tex]\frac{5}{4}x+1[/tex] is 5/4.
What is rate of change?The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time.
Given that the expression, y = [tex]\frac{5}{4}x+1[/tex].
To find the rate of change,
first we make the equation in standard form.
Slope intercept form ;
(y₂ - y₁) =m (x₂ -x₁) + c
Comparing the expression to the standard form;

brainiest marked
Answer:To find the mean of the heights of the 17 students, we need to add up all of the heights and divide the sum by the number of students. The sum of the heights is 1777 cm, and when we divide this by 17, we get a mean height of 104 cm.
To find the median of the heights of the 17 students, we first need to put the heights in order from least to greatest. The heights in order are 101,102,106,109,110,110,112,115,115,115,115,115,117,120,120,123,125. There are 17 students, so the median is the height of the 9th student, which is 115 cm.

A bank put $50 into a savings account when you opened the account. 12 weeks later, you have a total of $275. a. If y is the total amount of money in the savings account and x represents the number of weeks, write an equation in the form of y=mx+b that describes the situation. Be sure to show or explain how you got your answer.
Answer:
In this problem, we are looking for an equation in the form of y = mx + b that describes the situation where a bank puts $50 into a savings account when it is opened and 12 weeks later, the account has a total of $275.
To find the equation, we need to find the slope (m) and the y-intercept (b). The y-intercept is the point at which the line crosses the y-axis, which in this case is the initial amount of money in the account ($50). The slope is the rate at which the amount of money in the account is changing over time.
To find the slope, we can use the following formula:
slope = (y2 - y1) / (x2 - x1)
In this case, y2 is the total amount of money in the account after 12 weeks ($275), y1 is the initial amount of money in the account ($50), x2 is the number of weeks after the account is opened (12 weeks), and x1 is the number of weeks before the account is opened (0 weeks).
Plugging these values into the formula, we get:
slope = (275 - 50) / (12 - 0) = 225 / 12 = 18.75
Now that we have the slope, we can plug it into the equation y = mx + b, along with the y-intercept (b = 50), to get the final equation:
y = 18.75x + 50
This equation represents the situation described in the problem, where the bank puts $50 into a savings account when it is opened and 12 weeks later, the account has a total of $275.

Julie is considering enrolling in two courses: physics and chemistry. There is a 10% chance she will enroll in physics and a 45% chance she will not enroll in physics but enroll in chemistry. Given that her decision of enrolling in a course is independent of enrolling in other courses, find the probability she will not enroll in chemistry? Assume Event A: she enrolls in physics; Event B: she enrolls in chemistry.
If the decision of enrolling in the course in independent events, the probability of not enroll in chemistry is 0.55
The chances of enroll in physics = 10%
The chances of the not enroll in physics but enroll in chemistry = 45%
The probability is the ratio of the number of favorable outcomes to the total number of outcomes
The probability = Number of favorable outcomes / Total number of outcomes
Given that her decision of enrolling in a course is independent of enrolling in other courses
The probability of not enroll in chemistry = 1 - The probability of enroll in chemistry
Substitute the value in the equation
The probability of not enroll in chemistry = 1 - 0.45

Compare the graph to the graph of f(x) = | x |. Describe the shift of g(x).
g(x) = |x+4| - 2
g(x) is shifted 4 units left and -8 units down from f(x).
How would you define a graph's shift?Shifts. A shift is similar to a stiff translation in that it does not alter the size or shape of the function's graph. The graph's placement will only change as a result of a shift. A vertical shift maintains the x-coordinate while adding or subtracting a constant from each y-coordinate.In other words, we multiply the y-coordinate of each point on the graph of f by 2 to generate the graph of g. Geometrically, a point is moved 2 units above its former location by adding 2 to its y-coordinate. It is common to refer to "moving the graph up 2 units" when adding 2 to all of the y-coordinates on a graph at once.when y=f(x)
When y = f (x + a), the function is either shifted to the right by a units (a 0) or to the left by a units (a > 0).
g(x)=(x+4)-2⇒f(x−8)
This causes f (x) to be moved by 8 units to the right.

According to a recent pew research center report, many American adults have made money by selling something online. in a random sample of 4579 American adults, 914 reported that they earned money by selling something online in the previous year. assume the conditions for inference are met.
Here we need to construct a 98% confidence interval for the proportion of all American adults who would report having earned money by selling something online in the previous year.
As per the given question, the value of
Confidence interval = 98%
Number of samples = 4579
Reported numbers = 914
Therefore, the number of failure is calculated as,
=> 4579 - 914
=> 3665
Here the sample proportion is the number of successes divided by the sample size:
=> 941/4579
=> 0.1996
Here for confidence level 1 − α = 0.98,
We have to determine zα / 2 = z0.01 using the normal probability table in the appendix, we get

Then the margin of error is calculated as,
E = 2.33 x √[0.1996 x (1 - 0.1996)]/4579
E = 0.0137
Then the boundaries of the confidence interval are then:

select all of the factors of x3 5x2 2x 8 x 5 x3 x 4 x 1 x3 x 2
The all the factors of x³ + 5x² + 2x – 8 are (x+4)(x-1) and (x+2) , the correct options are (c) , (d) and (f) .
In the question ,
it is given that the equation is f(x) = x³ + 5x² + 2x – 8 ,
we have to find the factors of f(x) = x³ + 5x² + 2x – 8 .
We know that ,The Factor Theorem states if (x-t) is a factor of f(x) if and only if f(t)=0 .
So , Option(a) Let g(x) = x + 5 be a factor
that means for x = -5 , f(-5) = (-5)³ + 5(-5)² + 2(-5) – 8 = 2 ≠ 0 ,
hence it is not a factor .
In option (b) Let g(x) = x - 5 be a factor
that means For x = 3 , f(3) = (3)³ + 5(3)² + 2(3) – 8 = 70 ≠ 0 ,
hence it is not a factor .
In option (c) Let g(x) = x + 4 be a factor
that means For x = -4 , the equation is f(-4) = (-4)³ + 5(-4)² + 2(-4) – 8 = 0 ,
hence it is a factor .
In option (d) Let g(x) = x - 1 be a factor
that means For x = 1 , f(1) = (1)³ + 5(1)² + 2(1) – 8 = 0 ,
hence it is a factor .
In option (e) Let g(x) = x + 3 be a factor
that means For x = -3 , it becomes f(-3) = (-3)³ + 5(-3)² + 2(-3) - 8 = 4 ≠ 0 ,
hence it is not a factor .
In option (f) Let g(x) = x + 2 be a factor
that means For x = -2 ,the equation f(-2) = (-2)³ + 5(-2)² + 2(-2) - 8 [tex]=[/tex] 0 ,
hence it is a factor .
Therefore , the factors are (x+2) , (x - 1) and (x + 4) .
The given question is incomplete , the complete question is
Select all of the factors of x³ + 5x² + 2x – 8.
(a) x + 5
(b) x – 3
(c) x + 4
(d) x – 1
(e) x + 3
(f) x + 2

In a genetics class, 7 students have GREEN eyes, 4 students have BLUE eyes, and 10 have HAZEL eyes. If a single student is picked at random, what is the probability that their eyes are BLUE or HAZEL?
Provide the final answer as a simplified fraction.
Answer:
1/14
Step-by-step explanation:
all together the probability would be 1/21 because we're adding all the color eyes together. After that, it narrows to only blue and hazel which is 14 so the new probability is 1/14, so the answer is 1/14.
