Answer:
The correct answer is "-1.05".
Step-by-step explanation:
Given that,
Sample size,
n = 25
Sample mean,
[tex]\bar X=480[/tex]
Population standard deviation,
[tex]\sigma=95[/tex]
Null hypothesis,
[tex]H_0:\mu=500[/tex]
Alternate hypothesis,
[tex]H_0:\mu>500[/tex]
Then,
The p-value will be:
⇒ [tex]Z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]
By putting the values, we get
⇒ [tex]=\frac{480-500}{\frac{95}{\sqrt{25} } }[/tex]
⇒ [tex]=-\frac{100}{95}[/tex]
⇒ [tex]=-1.05[/tex]

Write an equation for the lowest-degree polynomial function, with the graph and intercepts shown in the figure. For this exercise, make the leading coefficient be 1 or -1
Answer:
f(x) = (x+1)² - 9
Step-by-step explanation:
We can start by seeing if this is a quadratic function, as that is the lowest degree polynomial possible.
The vertex form for a quadratic function is a(x-h)² + k, with the vertex being (h, k).
In this example, the leading coefficient (a) must be 1 or -1. If a is positive, the graph opens upward, and vice versa. Since the graph opens upward, a must be 1.
Our vertex in this picture is (-1, -9). We can plug those values in, along with a=1, to get
1(x-(-1))² - 9 = (x+1)² - 9
Therefore, our equation is f(x) = (x+1)² - 9
The polynomial is given by:
[tex]p(x) = x^2 + 2x - 8[/tex]
------------------------
Zeros of a function:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
------------------------
The polynomial has two x-intercepts, thus, the lowest-degree is 2.Concave up, thus, the leading coefficient is [tex]a = 1[/tex].The x-intercepts are [tex]x_1 = -4, x_2 = 2[/tex], and thus:[tex]p(x) = (x - (-4))(x - 2) = (x + 4)(x - 2) = x^2 + 4x - 2x - 8 = x^2 + 2x - 8[/tex]

Why do you think using computer software to do forecasting calculations is almost necessary if you are changing the number of time periods for a moving average or the alpha value for an exponential smoothing calculation
Answer:
There are two major methods of forecasting
One is the Causal method and the 2nd one is the times series method
Causal method mainly tries to find out cause and effect relation between variable and various factors impacting that variable while the time series method infuences the utilization of the historical data and mainly focus to forecast based on the trend present. It simply ignores the other variables. It just tries to give an idea of a trend, it can't predict the impact of other variables as in causal method.
Linear regression analysis can be utilized in both sort of estimating technique. By linear regression analysis we can anticipate effect of different factor on factor variable. It anticipate the pattern, yet additionally gives an idea about connection among variable and different elements affecting it. That is the reason Linear regression is considered as best technique for forecasting.
Presently, going to the next part of this inquiry, Time period utilized in moving normal is settled based on fluctuation showing up in how much period, to smoothen out the variation. Also, Alpha value is chosen dependent on the time span to smoothen out the variation in the information. Changing of time-frame or distinctive alpha will make estimation complex. And furthermore, it will make computation more probabilistic as opposed to deterministic which may create mistake whenever done by manual calculation. That is the reason program are important in such sort of computation

Based on the areas of the squares, determine whether the triangle shown is a right triangle.
The given triangle is not a right-angle triangle as the sides don't form a Pythagorean triplet.
What is the Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the le right triangle is equal to the square on the hypotenuse (the Pythagoras the right angle)—or, in familiar algebraic notation, a² + b² = c².
Given her: Three squares whose sides form one Pythagoreans of a triangle .
Now a²=58
b²=10
b=√10
c²=64
c=8
Clearly √10<√58<8
Thus c must be the hypotenuse of the triangle.
Using Pythagoras' theorem we get
√10²+√58²=68≠64
Hence, The given triangle is not a right angle triangle as the sides don't form a Pythagorean triplet.

The city of Raleigh has 10000 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 200 randomly selected registered voters was conducted. 72 said they'd vote for Brown, 118 said they'd vote for Feliz, and 10 were undecided. Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown. Note: The proportion should be a fraction or decimal, not a percent.
Answer:
0.36
Step-by-step explanation:
Given, There Are 10000 Registered Voters in a City & Two Candidates Brown & Felix .
The Day Before Election , A Telephonic Poll Of 200 Randomly Registered Voters Was Conducted .
72 said they would vote for Brown , 118 Said they would vote for felix & 10 Were Undicided .
Now, The sample statistic is the number who would vote for Brown divided by the total number in the sample, or 72/200 = 0.36
& To Find How Many of 10000 voters to vote Brown Just Multiply 0.36 With 10000 ⇔ 0.36×10000=3600

Answer:
Area of circle = 465.82 cm²
Step-by-step explanation:
Given the following data;
Circumference of the hub cap = 76.49 cm
Pie, π = 3.14
To find the area of the hub cap;
First of all, we would determine the radius of the hub cap.
Mathematically, circumfeence of a circle is equal to;
C = 2πr
Where:
C is the circumference of a circle.
r is the radius of a circle.
C = 2πr
76.49 = 2 * 3.14 * r
76.49 = 6.28r
Radius, r = 76.49/6.28
Radius, r = 12.18 cm
Next, we find the area of the hub cap;
Area of circle = πr²
Area of circle = 3.14 * 12.18²
Area of circle = 3.14 * 148.35
Area of circle = 465.82 cm²
However, if the circumference of the hub cap were smaller, the area of the hub cap would also be smaller. Thus, the circumference of a hub cap is directly proportional to the area of a hub cap.
