Step-by-step explanation:
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).

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.

Is 0.6 greater than 0.85?? ( 4th grade work)
Answer:
No its not
Step-by-step explanation:
Answer:
No, 0.85 is greater.
Step-by-step explanation:
Imagine a number line, with one at the end and 0.1 at the other end. With .85, It would be closer to one, with 0.6 being behind 0.85. The only other reason that 0.6 is greater than 0.85 is if they are converted to fractions.

Answer:
LA = 20π square units
SA = 36π square units
V = 16π cubic units
Step-by-step explanation:
The value of the radius is needed before any area calculations can be done. It can be found from the Pythagorean theorem:
r² + 3² = 5²
r = √(25 -9) = 4
__
The lateral area is given by the formula ...
LA = πrs . . . . . where r is the radius and s is the slant height
LA = π(4)(5)
LA = 20π square units
__
The surface area is the sum of the lateral area and the base area. The latter is the area of a circle of radius 4.
SA = πr² + LA
SA = π(4²) +20π = 16π +20π
SA = 36π square units
__
The volume is given by the formula ...
V = 1/3πr²h
V = 1/3π(4²)(3) = 16π
The volume is 16π cubic units.

if a×b=2a=b, evaluate 4×3 do not answer with a link,photo,file.
If you are comparing a*b=4*3, a = 4 and b = 3.
This would mean that 2a = 8.
If a×b=2a=b, evaluate 4×3 , Based on the given equation, the result of 4 × 3 is 12.
To evaluate 4 × 3 using the given information, we substitute the values of a and b into the equation.
An equation is a mathematical statement that shows the equality of two expressions or quantities. It consists of an equal sign (=) placed between the two sides of the equation. The expressions on each side of the equal sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation.
Equations are used to represent relationships and solve for unknown values. They can involve variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The goal is to find the value or values of the variable(s) that make the equation true.
Given: a × b = 2a = b
Let's assign a = 4 and b = 3:
4 × 3 = 2(4) = 3
Simplifying the equation:
12 = 8 = 3
Therefore, based on the given equation, the result of 4 × 3 is 12.

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

A Pew Research study finds that 23% of Americans use only a cell phone, and no land line, for making phone calls (The Wall Street Journal, October 14, 2010). A year later, a researcher samples 200 Americans and finds that 51 of them use only cell phones for making phone calls.Set up the hypotheses in order to determine whether the proportion of Americans who solely use cell phones to make phone calls differs from 23%.
Answer:
We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %
Step-by-step explanation:
A pew research finds that 23 % ( μ ) of Americans use only cell phone
Sample Information
sample size n = 200
x₁ = 51 then p₁ = 51/200 p₁ = 0,255
and q₁ = 1 - p ₁ q₁ = 1 - 0,255 q₁ = 0,745
Sample big enough for the approximation of the binomial distribution to the normal distribution
p₁*n = 0,255 * 200 = 51 > 5 and q₁*n = 0,745* 200 = 149 > 5
Test hypothesis
Null hypothesis H₀ p₁ = μ = 0,23
Alternative hypothesis Hₐ p₁ ≠ 0,23
Is a two tail test. We choose CI = 95 % then significance level is α = 0,05 %
α = 0,05 as is a two tail test α/2 = 0,025
from z-table z(c) = 1,96
To calculate z(s) = ( x - μ ) /√p₁*q₁/n
z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200
z(s) = 0,025 / 0,0308
z(s) = 0,81
Comparing z(s) and z(c)
z(s) < z(c) 0,81 < 1,96
Then z(s) is in the acceptance region: we accept H₀

The area of a circle is πr².
We have,
if a tangent and a chord are drawn from a point outside a circle, and the point of intersection of the tangent and the circle is labeled as point P, then the length of the tangent squared is equal to the product of the lengths of the two segments of the chord:
Now,
From the figure,
(2x - 9)² = 27 (2x + 2)
We can start by simplifying the left-hand side of the equation:
(2x - 9)² = 27 (2x + 2)
4x² - 36x + 81 = 54x + 54
Now we can move all the terms to one side and simplify:
4x² - 90x + 27 = 0
Next, we can use the quadratic formula to solve for x:
x = (-b ± √(b² - 4ac)) / 2a
where a = 4, b = -90, and c = 27.
Plugging in the values:
x = (-(-90) ± √((-90)² - 4(4)(27))) / 2(4)
x = (90 ± √(8100 - 432)) / 8
x = (90 ± √(7668)) / 8
x = (90 ± √(447)) / 8
x ≈ 11.16 or x ≈ 1.09
Rounding to a whole number.
x = 1
Therefore,
The value of x in the circle is 1.
