What is the standard normal distribution?
A continuous probability distribution for a real-valued random variable is called a normal distribution or a Gaussian distribution in statistics. Graphs make it simple to identify the following key traits of normal distributions: The mode, median, and mean are all equal. About the mean, the distribution is symmetric; half of the values are below and half are above the mean. Two numbers, the mean and the standard deviation, can be used to describe the distribution.

B(n)=2^n A binary code word of length n is a string of 0's and 1's with n digits. For example, 1001 is a binary code word of length 4. The number of binary code words, B(n), of length n, is shown above. If the length is increased from n to n+1, how many more binary code words will there be? The answer is 2^n, but I don't get how they got that answer. I would think 2^n+1 minus 2^n would be 2. Please help me! Thank you!
Answers
Answer:
The additional words is \(2^n\)
Explanation:
Given
\(B(n) = 2^n\)
Required
Determine the additional words; i.e. \(B(n + 1) - B(n)\)
From the given parameters, we have that;
B is a function of n
Such that;
\(B(n) = 2^n\)
To calculate \(B(n+1)\), we simply substitute n + 1 for n
\(B(n) = 2^n\)
\(B(n + 1) = 2^{n + 1}\)
Applying laws of indices
\(B(n + 1) = 2^{n} * 2^1\)
\(B(n + 1) = 2^{n} * 2\)
\(B(n + 1) = 2(2^{n})\)
Calculating Additional Binary Code;
\(B(n + 1) - B(n)\)
Substitute values for B(n + 1) and B(n)
\(B(n + 1) - B(n) = 2(2^n) - 2^n\)
Express \(2^n\) as \(2^ n * 1\)
\(B(n + 1) - B(n) = 2(2^n) - 2^n * 1\)
Express 1 as \(2^0\)
\(B(n + 1) - B(n) = 2(2^n) - 2^n * 2^0\)
Factorize
\(B(n + 1) - B(n) = 2^n(2 - 2^0)\)
\(B(n + 1) - B(n) = 2^n(2 - 1)\)
\(B(n + 1) - B(n) = 2^n(1)\)
\(B(n + 1) - B(n) = 2^n\)
Hence, the additional words is \(2^n\)
2. In its first year, “DM Trading” had the following experience: Unit selling price birr 100 Sales 50,000 units Total fixed cost birr 400,000 TVC birr 3,000,000 Required: a) Develop TR, TC and profit functions for the company in terms of quantity b) Find the breakeven point in terms of quantity and sales volume.
Answers
a) The total revenue (TR) function can be calculated by multiplying the unit selling price by the quantity sold.
In this case, TR = 100 * Q, where Q represents the quantity sold. The total cost (TC) function consists of the sum of fixed costs (FC) and total variable costs (TVC). Given that the fixed costs are 400,000 birr and the TVC is 3,000,000 birr, the TC function can be expressed as:TC = FC + TVC = 400,000 + 3,000,000 = 3,400,000 birr.
The profit function (P) can be determined by subtracting the total cost from the total revenue, so P = TR - TC = 100Q - 3,400,000 birr.
b) The breakeven point can be found by setting the profit function equal to zero, as this is the point where total revenue equals total cost.
In this case, 100Q - 3,400,000 = 0. Solving for Q, we find Q = 3,400,000 / 100 = 34,000 units. Therefore, the breakeven point in terms of quantity is 34,000 units. To calculate the sales volume at the breakeven point, we can multiply the breakeven quantity by the unit selling price:Sales Volume = 34,000 units * 100 birr/unit = 3,400,000 birr. Hence, the breakeven point in terms of sales volume is 3,400,000 birr.

The 2007 map shows a large portion of the Midwest in white. The west coast is largely yellow and orange. The east coast and central part of the U.S. are also largely yellow and orange. There are a few scattered splotches of red, and a very few purple and gray areas. The 2009 map is dramatically different.

In 10 > 4x + 2 which inequality represents the possible range of values of 9x + 4
Answers
Answer:
9x+4<22
Explanation:
Inequalities are solved in the same way as normal equations, we just need to start by isolating the x term on one side so we can solve for it on the other side, which we can do by doing the same thing to both sides to cancel out the other term and the coefficient:
10 -2 > 4x +2 -2
8 > 4x
8/4 > 4x/4
2 > x
This means x can be anything less than 2.
So now we can find the maximum value for the equation by substituting x:
9(2) + 4 = 22
That is the maximum value if x is 2, but because x has to be less than two, the possible range of values for 9x+4 will all be less than 22.
9x+4<22

Answers
Answer:
this is a SAT college question that involves solving a system of equations with two variables, P and G. P represents the number of hours of heat from a pellet stove, and G represents the number of hours of natural gas heat. The equation 0.30P+0.25G=570 means that the total cost of heating for one month is 570 dollars, where 0.30 dollars is the cost per hour of pellet stove heat and 0.25 dollars is the cost per hour of natural gas heat.
The question also gives another equation: P+G=57, which means that the total number of hours of heating for one month is 57 hours.
To find how many therms per hour does the pellet stove output, we need to solve this system of equations for P and G, and then use another formula that relates therms to kilowatt-hours (kWh).
one therm (US) is equal to 29.3001111 kWh.
We can use substitution or elimination method to solve the system of equations:
Using substitution:
P+G=57 P=57-G
Substitute P into the first equation:
0.30(57-G)+0.25G=570 17.1-0.30G+0.25G=570 -0.05G=-552.9 G=11058
Plug G into either equation to find P:
P+11058=57 P=-11001
Using elimination:
Multiply both sides of the second equation by -0.25:
P+G=57 -0.25P-0.25G=-14.25
Add both equations together:
(0.30P-0.25P)+(0.25G-0.25G)=570-14.25 0.05P=55575 P=-111015
Plug P into either equation to find G:
-111015+G=57 G=11072
We can see that both methods give us the same values for P and G.
Now we can use these values to find how many therms per hour does the pellet stove output.
We know that one therm (US) is equal to 29.3001111 kWh, so we can write:
Therms per hour = kWh per hour / 293001111
We also know that kWh per hour = Cost per hour / Cost per kWh.
in February 2023, the average cost per kWh in Kentucky was $0.11.
So we can write:
Therms per hour = (Cost per hour / $011) / 293001111
For pellet stove heat, we have:
Therms per hour = ($030 / $011) / 293001111 Therms per hour = ~0000036
Therefore, the pellet stove outputs about 0000036 therms per hour.

What is the t-statistic?
Answers
In statistics, the t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. It is used in hypothesis testing via Student's t-test. The t-statistic is used in a t-test to determine whether to support or reject the null hypothesis.
The t-statistic is a measure of the difference between the mean of a sample and the mean of the population, in units of the standard error. It is calculated by taking the difference between the sample mean and the population mean, dividing by the standard error of the mean, and then multiplying by the square root of the sample size.
The formula for the t-statistic is:
t = (sample mean - population mean) / (standard error of the mean)
The t-statistic is used in hypothesis testing to determine whether a sample mean is significantly different from a population mean. The t-distribution is used to calculate the probability (p-value) of observing a t-statistic as extreme as the one obtained from the sample, assuming the null hypothesis is true.

Note that since from the results, the null hypothesis is rejected, it can be deduced that there is strong proof that the distribution of digits in the directory is NOT uniformly distributed.
What is a null hypothesis?The null hypothesis in inferential statistics states that the two options are the same. The null hypothesis states that the observed difference is solely attributable to chance. The likelihood that the null hypothesis is true may be calculated using statistical testing.
In the above scenario, the chi-square statistics will be used.
Sample size; n = 10
Chi-square test statistic is:
X²ₙ₋₁ = (Oi - Ei)² /Ei
Where Oi = Observed Frequency; and
Ei = Expected Frequency
Note that the Mathematical Expression for Expected Frequency is:
Ei = (O₁ + O₂ + .....+ Oₙ)/n
= (1026 + 1107 + ....+ 853)/10
= 10,000/10
= 1,000
The hypotheses is described as:
H₀: The distribution of digits in the directory follows a uniform distribution.
Hₐ: The distribution of digits in the directory does not follow a uniform distribution.
From the above, the test statistics using a spreadsheet are computed as follows: X²\(_{cal}\) test statistic = 58.542
Next, we examine the Degree of Freedom (DF).
Df = (n-1)
= 10 - 1
= 9
Thus, the critical value computed using X² distribution table is 16.92.
Since X²\(_{cal}\) (58.542) > X²\(_{tab}\) (16.92), the null hypothesis is rejected. Hence, it is correct to state that there is good evidence that the distribution of digits in the telephone directory is no uniformly distributed.
