Domain: All real numbers, or (-∞,∞) depending on how you want to write it.
Range: [-4, ∞)
Vertex: (-2, -4)
Axis of symmetry: x = -2
Interval of increase: (-2, ∞)
Interval of decrease: (-∞, -2)
Y-int: (0, 0)
X-int/Zero/Solution(s): (-4, 0) and (0, 0)
For a polynomial function like this, which is a quadratic function, the domain is always negative infinity to positive infinity, or all real numbers.
The range is the lowest y-value to the highest y-value. The lowest y-value for this is at the vertex, but the function has no upper limit for the y-value.
The vertex is the point that you can very clearly see is at the tip of the graph.
Axis of symmetry is the vertical line that splits the graph in half at the vertex.
Interval of increase is the interval x values for which the function is increasing. The function increases to the right of the vertex.
Interval of decrease is to the left of the vertex.
The y-intercept is clearly (0, 0), where the graph intersects the y-axis.
The x-intercepts are also clear, since you can see where the graph intersects the x-axis.

A poll was conducted during the final game of the basket season to determine whether fans wanted to see the defending champions win the game or the challenging team win the game. From the poll, 216 of the 374 residents sampled from urban areas want the defending champions to win the game. In more rural areas, 304 of the 466 residents polled want the defending champions to win the game. Assuming lo an has nothing to do with team preference, the probability that the data gathered was the result of chance is calculated to be 0.03. What is the correct interpretation of this calculation?
Answers
There will be a significant difference between the two proportions. A further explanation is given below.
As shown by the data, families in remote regions are much more likely to desire the protecting winners to control the tournament than individuals throughout large cities, and this difference is statistically substantial.Throughout this case, it's because the p-value of further 0.03 would be significantly less than the threshold of 0.05 significance. As a result, we may claim that perhaps the results are statistically significant at such a 0.05 range.
Thus the above is the appropriate solution.

There are 3 evens given the 6 numbers
P(even) = 3/6 =1/2
There is 1 head on a two sided coin
P(head) = 1/2
Multiply the probabilities together since they are independent events

YES
Step-by-step explanation:
Any line that is tangent to a circle is always perpendicular to the radius of the circle, forming a right angle at the point of tangency.
Therefore, ∆BAC is a right triangle if it satisfy the pythagorean triple rule which says that c² = b² + a²
Where,
c = the hypotenuse = 30
b = 24
a = 2(9) = 18
Thus:
30² = 24² + 9²
900 = 900 (this is true)
Therefore, line AB is tangent to circle O.
The answer is YES

Chad completed 75% of a book when he read the first 180 pages. How many pages are in the book?
Answers
Answer:
240
Step-by-step explanation:
If 75% is 180, we need to find the remaining 25%.
Obviously, 25 is 1/3 of 75 (and "of" is another word for times) meaning that to find 25%, multiply 75% by 1/3.
Since 75% = 180, we do:
180 x 1/3
60
Now add these two values together to get:
180 + 60 = 240
The answer is 240

Caroline has a unique pet chimpanzee that is relatively likely to have twins. Each pregnancy is independent, and Caroline's chimpanzee has a 60% chance of having 1 baby and a 40% chance of having 2 babies each
pregnancy
If X is a random variable that represents the total number of chimpanzee babies if Caroline's chimpanzee gets
pregnant twice, drag the bars to graph the probability distribution for all possible values of X.
Answers
Based on the graph, we can see that the possible values of X are 2, 3, and 4. The probability of X = 2 is 0.36, the probability of X = 3 is 0.48, and the probability of X = 4 is 0.16.
What is probability?Probability is a measure of the likelihood of an event occurring. It is usually expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
Based on the graph, we can see that the possible values of X are 2, 3, and 4. The probability of X = 2 is 0.36, the probability of X = 3 is 0.48, and the probability of X = 4 is 0.16.
We can also see that the distribution is skewed to the right, meaning that the most likely outcome is X = 3, which occurs with a probability of 0.48.
This makes sense, since the chimpanzee is more likely to have 2 babies in one pregnancy and 1 baby in the other, which would result in a total of 3 babies.
Thus, the graph provides a visual representation of the probability distribution for X and helps us to understand the relative likelihood of each possible outcome.

In a lab experiment, the decay of a radioactive isotope is being observed. At the
beginning of the first day of the experiment the mass of the substance was 500 grams
and mass was decreasing by 9% per day. Determine the mass of the radioactive
sample at the beginning of the 17th day of the experiment. Round to the nearest tenth
(if necessary).
Answers
Answer:
Approximately 110.6 grams remain at the beginning of the 17th day.
Step-by-step explanation:
At the beginning of the first day, the mass of the substance was 500 grams.
It decreases by 9% per day.
And we want to determine the mass of the sample at the beginning of the 17th day.
First, we need to find our ratio of decay. Since it decreases by 9% or 0.09 each day, the mass of the substance after each subsequent day will be 100% - 9% or 1 - 0.09 or 0.91 of the previous day.
We can write a exponential function to model this. An exponential function has the form:
[tex]f(x)=ar^x[/tex]
Where a is the initial term and r is the rate.
Let x represent the number of days after the first day. Substitute 500 for a and 0.91 for r:
[tex]f(x)=500(0.91)^x[/tex]
The 17th day is 16 days after the first day. So, the amount of mass remaining on the beginning of the 17th day is when x = 16. Substitute:
[tex]f(x)=500(0.91)^{16}[/tex]
Approximate. Therefore:
[tex]f(x)\approx110.6\text{ grams}[/tex]
Approximately 110.6 grams remain at the beginning of the 17th day.

What is a confidence interval?A confidence interval is a range of values that are constrained by the statistic's mean and that is likely to include an unidentified population parameter. The proportion of likelihood, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn several times is referred to as the confidence level.

A pair of shoes that normally sells for $85.00 goes on sale for 35% off. Season thinks that the sale price should be $50.00 but Melanie disagrees and says the price should be $55.25. Aiyanna says they are both wrong and decides the price should be $29.75. Who is correct and why?
Answers
Answer:
Melanie is correct
Step-by-step explanation:
35% of 85 is 29.75 so take that away from the original price and you get 55.25
This means the price will be 55.25$
Answer:
Melanie is correct since 65% of $85.00 is $55.25.
Step-by-step explanation:
The original price of the shoes is $85.00. That is 100% of the price of the shoes since 100% is a whole amount.
The discount on the shoes is 35%.
100% - 35% = 65%
That means the sale price is 65% of the original price. Now we calculate 65% of $85.00.
65% of $85.00 =
= 0.65 * $85.00
= $55.25
Answer: Melanie is correct since 65% of $85.00 is 55.25.
