Completed question:
In the game of tic-tac-toe, if all moves are performed randomly the probability that the game will end in a draw is 0.127. Suppose six random games of tic-tac-toe are played. What is the probability that at least one of them will end in a draw?
Answer:
0.557
Step-by-step explanation:
For each game, the probability of not end in a draw is 1 - 0.127 = 0.873. Thus, because each game is independent of each other, the probability of all of them not end in a draw is the multiplication of the probability of each one:
0.873x0.873x0.873x...x0.873 = 0.873⁶ = 0.443
Thus, the probability that at least one of them end in a draw is the total probability (1) less the probability that none of them en in a draw:
1 - 0.443
0.557
Answer: g(x) = (x + 1)² + 3
Step-by-step explanation:
The vertex form of a quadratic equation is: y = a(x - h)² + k where
f(x) = x²
Given: 3 units up --> k = 3
1 unit left --> h = -1
g(x) = (x + 1)² + 3
The translation of the graph of a function is one where the graph is moved to a different location on the plane that does not include a change in shape or rotation
The resulting function from the translation of the function f(x) = x², 3 units up and 1 unit left, g(x) = x² + 2·x + 4
The process by which the above value for g(x) is found is presented as follows:
The given function f(x) = x²
The vertical translation given to the function = 3 units up
The horizontal translation given to the function = 1 unit left
The required parameter;
To find the resulting function g(x) that has results from the given translations
Solution:
A translation of a function y = f(x) vertically,k units upwards is the function y = f(x) + k
A translation of a function y = f(x) horizontally, k, units left, is the function y = f(x + k)
Therefore, we get
g(x) = f(x + 1) + 3 = (x + 1)² + 3 = x² + 2·x + 4
g(x) = x² + 2·x + 4

Question
Consider a simple economy where the basket of goods used to calculate the CPI contains two items shampoo and soap.
The basket consists of 1 bottle of shampoo and 2 bars of soap. The prices are shown in the table.
Year Price of a Bottle of Shampoo Price of a Bar of Soap
Year
36 50
$1.25
Year
$5.00
$1.30
Type the correct answer in the box. Round your answers to two decimal places, if necessary.
The CPI for year 2 is
Submit
Answer:
2.22%
Step-by-step explanation:
Recall that year 1, the base year, has a CPI of 100.
From question 1, we know that the CPI of year 2 is 102.22.
To find the rate of inflation, find the percent change from year 1 to year 2:
102.22-100= 0.0222, or 2.22%
_________
100
The CPI for year 2 can be calculated by finding the total cost of the basket of goods in year 2 and comparing it to the total cost in the base year.
The solution of CPI is 197.40
The CPI (Consumer Price Index) for year 2 can be calculated by first finding the total cost of the basket of goods in year 2 and then comparing it to the total cost in the base year.
In this case, the basket consists of 1 bottle of shampoo and 2 bars of soap.
The price of a bottle of shampoo in year 2 is $5.00 and the price of a bar of soap is $1.30.
So, the total cost of the basket in year 2 is (1 * $5.00) + (2 * $1.30) = $7.60.
Next, we need to find the total cost of the basket in the base year, which is given as $1.25 for a bottle of shampoo and $1.30 for a bar of soap.
So, the total cost in the base year is (1 * $1.25) + (2 * $1.30) = $3.85.
Finally, we can calculate the CPI for year 2 by dividing the total cost in year 2 by the total cost in the base year and multiplying by 100:
CPI = (Total cost in year 2 / Total cost in base year) * 100 = ($7.60 / $3.85) * 100 = 197.40 (rounded to two decimal places).

Answer:
Reject the null hypothesis.
Step-by-step explanation:
n1 = 16
n2 = 21
S.V1 = 5.8
S.V2 = 2.4
= 0.05
= Population Variance 1 ≤ Population Variance 2
= Population Variance 1 > Population Variance 2
Test statistic value = 5.8 / 2.4 = 2.417
Degrees of freedom is n - 1
15 and 20
Critical value is = 2.2
2.417 > 2.2
we reject the null hypothesis as the critical value is greater than the test statistic.
