The formula to calculate the difference between two standard deviations of populations n1 and n2 is:
sigma (difference)=√(sigma1/n1 + sigma2/n2). For this scenario:
sigma(d)= √(49/100 + 36/50)
Thus, the calculated standard deviation of the difference equals 1.1.
Answer:
E. P(W | H)
Step-by-step explanation:
Meaning of each probability:
P(H): Likelihood of the game occurring at home
P(W): Likelihood of the game resulting in a win.
P(H and W): Likelihood that the game is both at home and a win.
P(H|W): Likelihood of a win occurring when at home.
P(W|H): Likelihood of winning at home games.
Which probabilities are necessary to determine the fraction of home games that were victories?
This is the probability of winning a home game. Hence, the answer is:
E. P(W | H)
Response:
Second option: 
Third option: 
Detailed explanation:
The missing graph has been provided.
The attached image illustrates the graphing of the following system of linear equations:
Notice the intersection of the lines.
According to the definition, if lines in a system of equations intersect, then there is only one solution. This implies that the intersection point is the solution to that system. This can be expressed as:
Represented by "x" for the x-coordinate and "y" for the y-coordinate.
Here, it's noticeable that:
- The x-coordinate of the intersection point lies between 
and 
.
- The y-coordinate of the intersection point is situated between 
and 
.
Therefore, you can conclude that the forthcoming points (Refer to the options given in the exercise) are potential approximations for this system:
Hello! C and D aren't correct answers, as they fall downward due to gravity. The object accelerates downward at -10 m/s, resulting in an increasing speed as it descends, going beyond 10 m/s, which indicates that speed isn't steady. Hence, the correct answer is A.
(2 6/7) divided by (1 2/3) equals x over 1.
Cross-multiply and convert mixed numbers to improper fractions:
(5/3)x = 20/7
Solving for x:
x = (20/7) × (3/5)
x = 60/35, which simplifies to 1 5/7 songs per minute.
