What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
we have to use the drawing tool(s) to form the correct answer on the provided graph:
The function is given as
h(x) =(x - 1)^2 - 9
The x-intercept
Set h(x) to 0
So, we have
(x - 1)^2 - 9 = 0
Add 9 to both sides
(x - 1)^2 = 9
Take the square root of both sides
x - 1 = ±3
This gives
x = 1 ± 3
Expand
x = (1 - 3, 1 + 3)
Evaluate
x = (-2, 4)
Hence, the x-intercepts are x =2 and x = 4
The y-intercept
Set x to 0
So, we have
h(0) = (0 - 1)^2 - 9
Evaluate
h(0) = -8
Hence, the y-intercept is h(x) =-8
The vertex
We have
h(x) =(x - 1)^2 - 9
Expand
h(x) = x^2 - 2x + 1 - 9
Differentiate
h'(x) = 2x - 2
Set to 0 and solve for x
2x - 2 = 0
This gives
x = 1 --- this represents the axis of symmetry
Substitute x = 1 in h(x) =(x - 1)^2 - 9
h(1) =(1 - 1)^2 - 9
Evaluate
h(1) = -9
Hence, the vertex of the function is (1, -9)

A probability model includes p(red)=2/7 and P(blue)=3/14. Select all the probabilities that could complete the model.
Answer Key:
A: P(green)= 2/7, P(yellow)=2/7
B: P(green)=3/8, P(yellow)=1/8
C: P(green)=1/4 P(yellow)=1/4
D: P(green)= 5/21 Pyellow)= 11/21 E. P(green)= 3/7 P(yellow)=1/14
Answer:
The answer is "Option D".
Step-by-step explanation:
In this question, the shape of the model is not declared that why we assume that it has four sides in which two sides are given that is:
[tex]\to P(red)=\frac{2}{7} \\\\\to P(blue)=\frac{3}{14}[/tex]

Answer:
66 cm²
Step-by-step explanation:
The area of the polygon is the sum of the areas of the triangle and the rectangle it sits on. The dimensions of the triangle can be found by examining the top/bottom dimensions shown and the left/right dimensions shown.
The width (base) of the triangle is the difference between the lengths of the bottom and top horizontal lines: (12 -9) cm = 3 cm.
The height of the triangle is the difference between the lengths of the left and right sides of the figure: (9 -5) cm = 4 cm.
The dimensions of the rectangle are shown a the bottom and the left sides of the figure.
triangle area = 1/2bh = 1/2(3 cm)(4 cm) = 6 cm²
rectangle area = LW = (12 cm)(5 cm) = 60 cm²
Total polygon area = 6 cm² + 60 cm² = 66 cm²
-2 is the ________ of 2
Answer: -2 is the numerical opposite of the number 2. Any numbers opposite is it's negative form. (except for 0 due to there being no opposite for something that is not negative or positive.)
This table shows the number of girls enrolled in school by class. If a student is chosen at random from this group, which is the probability that a senior will be chosen?
Table :
Freshman - 165
Sophomore - 145
Junior - 114
Senior - 102
Answer:
102/526
Step-by-step explanation:
This would be the answer because when u add the amount of freshman plus sophomore plus juinior and plus senior, you get the result of 526. so that would be the denominator while the number of seniors would be the numerator...
Answer:
0.19 (I think)
Step-by-step explanation:
The pervious person just put 102/526. But if you convert that into a decimal it gives you
0.19391634980989
Just round it and you have 0.19

ΔIKG right angled triangle
Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.
GI² = IK² + GK²
=> GI² = 3² + 2²
=> GI² = 13
=> GI = √13
using distance formula
G (6,4) and I (3,2)
= √(6 - 3)² + (4 - 2)²
= √3² + 2²
= √9 + 4
= √13

where the line crosses the x-axis (could be once or mulitple times.) Find by taking the function, solving it until you have 1 or multiple binommials (they should be in parenthesis), and then making them equal to one. For example i would write x - 2 = 0 which would end up being x = 2. The coordinate would be (2,0).

The area of a rectangular closet is 18 square feet. The perimeter is 18 feet. What are the dimensions of the closet?
Answer:
Height: 6ft
Base: 3 ft
Step-by-step explanation:
Factors of 18 are: 1, 2, 3, 6, 9, 18
18 and 9 are both two big because of perimeter...this rules out 2 and 1 because those are the factor pairs which leaves 6 and 3
Area = bh = 3*6 = 18
Perimeter is adding all the sides twice
(6*2) + (3*2) = 12 + 6 = 18
Area = 18 Correct
Perimeter = 18 Correct

Hypothesis Testing is the use of statistics to determine the probability that a given claim is true. In Part II of this project, you will choose a data set, review claims and perform hypothesis testing and make a decision. You will then complete a write-up that includes the calculations. The government logs the number of documented births, deaths, marriages and divorces; however, it is possible to have undocumented cases. In part II of this project, you are going to test claims about total births, deaths, marriages and divorces. Deliverables Choose a Data Set. Go to https://www.cdc.gov/nchs/products/nvsr.htm (Links to an external site.) In the search bar type: Births, Marriages, Divorces, and Deaths screenshot of CDC website toolbar Pick a DataSet and download the PDF document and make note of the volume, number, and date. For example you could use the National Vital Statistics Reports, screenshot of National Vital Statistics Reports webpage Pick the same month/year combination for each data set. For example, choosing September of 2009. screenshot of example dataset Preliminary Calculations Create a summary table for 1. Live Births, 2. Deaths, 3. Marriages, and 4. Divorces highlighting the mean, median, sample standard deviation, minimum and maximum values for each the data sets. You will have FOUR tables using the list of values of each state, the District of Columbia and Puerto Rico (You will have 52 numbers for each data set). Summary Table for _________ Mean Median Standard Deviation Minimum Maximum Hypothesis Testing With the information that you gather from the summary tables, test the following (you can use excel when appropriate): Determine if there is sufficient evidence to conclude the average amount of births is over 5000 in the United States and territories at the 0.05 level of significance. Determine if there is sufficient evidence to conclude the average amount of deaths is equal to 6000 in the United States and territories at the 0.10 level of significance. Determine if there is sufficient evidence to conclude the average amount of marriages is greater or equal to 2500 in the United States and territories at the .05 level of significance. Determine if there is sufficient evidence to conclude the average amount of divorces is less than or equal to 4000 in the United States and territories at the 0.10 level of significance. For each of the tests above, in your report, be sure to— Clearly state a null and alternative hypothesis Give the value of the test statistic Report the P-Value Clearly state your conclusion (Reject the Null or Fail to Reject the Null) Explain what your conclusion means in context of the data. Lastly, propose and conduct your own test of hypothesis about the Birth, Death, Marriage and Divorce data that you have been analyzing. Make sure to follow the five steps above.

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
In a shoe store survey there are 200 customers.
Given in the table is that, people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.
We have been asked what percentage of people have basketball shoes.
People having basket ball shoes = 0.18 × 200 + 0.28 ×200
= 64
Thus, The percentage of people wearing basket ball shoe is,
= 64/200 x 100
= 32 %
