Step-by-step explanation:
white 47.7%,
mulatto (mixed white and black)
43.1%, black 7.6%,
Asian 1.1%,
The independent variable for this function is the number of items wrapped while the dependent variable is the cost to wrap the gifts. This is because the independent variable refers to the input to the function while the dependent variable is the output of the function. In this case, the function is expressed as:
C = 3 + 1(X)
where,
C = cost of wrapping the gifts
X = number of items wrapped
Answer:
Sum: 17 + 11 = 28
Difference: 17 - 11 = 6
Step-by-step explanation:
The sum of x and y is 28. In other words, x plus y equals 28 and can be written as equation A:
x + y = 28
The difference between x and y is 6. In other words, x minus y equals 6 and can be written as equation B:
x - y = 6
Now solve equation B for x to get the revised equation B:
x - y = 6
x = 6 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 28
6 + y + y = 28
6 + 2y = 28
2y = 22
y = 11
Now we know y is 11. Which means that we can substitute y for 11 in equation A and solve for x:
x + y = 28
x + 11 = 28
X = 17
Summary: The sum of two numbers is 28 and their difference is 6. What are the two numbers? Answer: 17 and 11 as proven here:
Sum: 17 + 11 = 28
Difference: 17 - 11 = 6
Answer:
Among the given options, the one which can be used as a minimum qualifying score to join the volleyball league is, 274.
Step-by-step explanation:
Let the team tryout scorecard is represented by the random variable X.
Now, according to the question,
X 
Normal (250 , 15)
Let Z = 
-----------------------(1)
So, Z Normal (0, 1)
According to the question, the bottom 95% in the tryout scorecard are to be eliminated.
Let, P(Z ≤ 
) = 0.95
Now, from the inverse standard normal probability table,
= 1.645
So, if we say that
P(X ≤ 
) = 0.95, then
--------------[from (1)]
= 
= 274. 675
Hence, from the given options, the answer is, 274.
