The approximate number of price increases needed to maximize profit is 2.5
How to determine the number of price?From the question, we have the following parameters that can be used in our computation:
x = number of price increases
y = Profit
Also from the question, we have
Begins at (0, 50)
Increases to (2.5, 81.25)
Decrease through (6.531, 0)
This means that
Maximum = (2.5, 81.25)
Recall that
x = number of price increases
So, we have
x = 2.5
Hence, the number of price increases is 2.5

Work out the new height after the increase.

What is percentage increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage. To calculate the percentage we need to have the initial value and the increased (new) value. In other words, we can say that percentage increase is a measure of percent change which gives the extent to which a quantity gains magnitude.
therefore %increase =( final value- initial value)/initial value ×100
let the final height of bush be x
15= (x-180)/180 ×100
2700= 100x-18000
collect like terms
2700+18000=100x
100x= 20700
divide both sides by 100
x= 20700/100
x= 207cm
therefore the new height of the bush is 207cm

which function in the random library will generate a random integer from 0 to the parameter value inclusive?
The function in the random library that generate a random integer from 0 to the parameter value inclusive is random.randint() function
What is a function?Functions are another key idea in programming because they let you put a piece of code that performs a specific purpose inside a specified block and then call that code whenever you need it with a single, brief command rather than repeatedly typing the same code.
What are parts of a function in coding?Code units that are "self contained" and carry out a particular purpose are called functions. Typically, functions "take in," "process," and "return" data and results. Once a function has been developed, it may be utilized countless times.

You want to find x, given that the external angle adjacent to a base angle of an isosceles triangle is (5x +12)°, and the other base angle is marked (3x +8)°.
Base anglesThe base angles of an isosceles triangle are congruent, so the other base angle is congruent to the marked base angle.
The external angle and the adjacent base angle are a linear pair, hence supplementary.

Wyatt went to the grocery store and bought bottles of soda and bottles of juice. Each bottle of soda has 30 grams of sugar and each bottle of juice has 40 grams of sugar. Wyatt purchased 2 more bottles of juice than bottles of soda and they all collectively contain 430 grams of sugar. Write a system of equations that could be used to determine the number of bottles of soda purchased and the number of bottles of juice purchased. Define the variables that you use to write the system.
Please answer with the format.
A system of equations that could be used to determine the number of bottles of soda purchased and the number of bottles of juice purchased are as follows;
Let S = number of bottles of soda.
Let J = number of bottles of juice.
System of Equations:
30S + 40J = 430
J = 2 + S
How to write a system of linear equations?In order to write a system of linear equations to describe this situation, we would assign variables to the number of bottles of soda and number of bottles of juice respectively, and then translate the word problem into algebraic equation as follows:
Let the variable S represent the number of bottles of soda that Wyatt bought.Let the variable J represent the number of bottles of juice that Wyatt bought.Since each bottle of soda has 30 grams of sugar and each bottle of juice has 40 grams of sugar with both of them having a sum total of 430 grams of sugar, we have the following equation:
30S + 40J = 430 .....equation 1.
Wyatt purchased 2 more bottles of juice than bottles of soda;
J = 2 + S .....equation 2.

Sampling:
In statistics, quality assurance, and research methodologies, sampling is the selection of a subset of individuals (statistical sample) from a statistical population in order to estimate characteristics of the population as a whole. A statistician tries to collect a representative sample of the population in question. Sampling is less costly than measuring the entire population, provides faster data collection, and can provide insight when the entire population cannot be measured.
Stratified Sampling:
When the population embraces a number of distinct categories, the frame can be organized by these categories into separate "strata." Each stratum is then sampled as an independent sub-population, out of which individual elements can be randomly selected. The ratio of the size of this random selection (or sample) to the size of the population is called a sampling fraction. There are several potential benefits to stratified sampling.
There are, however, some potential drawbacks to using stratified sampling.
First, identifying strata and implementing such an approach can increase the cost and complexity of sample selection, as well as leading to increased complexity of population estimates.
Second, when examining multiple criteria, stratifying variables may be related to some, but not to others, further complicating the design, and potentially reducing the utility of the strata.
Finally, in some cases (such as designs with a large number of strata, or those with a specified minimum sample size per group), stratified sampling can potentially require a larger sample than would other methods (although in most cases, the required sample size would be no larger than would be required for simple random sampling).

The second-smallest positive integer that, when divided by 3, leaves a remainder of 2, and when divided by 7, leaves a remainder of 3 is 38
Given that,
We have to find the second-smallest positive number that, when divided by 3, leaves a remainder of 2, and when divided by 7, leaves a remainder of 3.

Thus , option a)human brains evolved to notice how often things occur, not how likely they are to occur is correct
What does probability mean as a process?Probability theory deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is expressed as a number between 0 and 1, with 1 typically signifying certainty and 0 typically signifying impossibility.

b) f(5) = -8
c) f(0) = -3
d) you need to circle the points (-3, 0) and (-10, 7)
How to evaluate the linear function?Here we have the following linear function:
f(x) = -x - 3
We want to graph that line, but first let's evaluate as it asks in the steps below.
To evaluate the function, we only need to replace the variable x by the correspondent number.
a) f(-4)
Here just replace the variable x by the number -4, you will get:
f(-4) = -(-4) - 3
f(-4) = 4 - 3
f(-4) = 1
b) Here we will do the same thing:
f(5) = -5 - 3
c) f(0) = -0 - 3
f(0) = -3
d) To see which points are in the line, just replace the values of the point in the given equation. If the equation remains true, then the point is on the line.
For example, the first one (-3, 0) will give:
0 = -(-3) - 3
0 = 3 - 3
0 = 0
That equation is true, so the point is on the line.
The point (-10, 7) is also on the line:
7 = -(-10) - 3
7 = 10 - 3
7 = 7
Finally, let's do the graph.
Now you know that (-10, 7) and (-3, 0) are points on the line, you can graph these in the coordinate axis and connect them with a line.
the graph of the linear equation can be seen in the image below.
