Complete question :
John and Kamira are playing a game. John's score (J) and Kamira's score (K) after round 1 are shown on the number line.
The score recorded at the end of the first round is 2.
What could this score represent?
Options :
the sum of John's score and Kamira's score
the difference between John's score and Kamira's score
the absolute value of the difference of John's score and Kamira's score
the sum of the absolute value of John's score and the absolute value of Kamira's score
Answer:
the sum of John's score and Kamira's score
Step-by-step explanation:
Given that :
The score recorded at the end of the round is 2
From the attached number line :
John's score = - 5
Kamira's score = 7
Sum = - 5 + 7 = 2
Difference = - 5 - 7 = - 12
Sum of absolute value = 5 + 7 = 12
absolute value of difference = 12
Answer: B. 

Step-by-step explanation:
Let
be the proportion of all U.S. adults that smoked in 1995. Let
denote the proportion of all U.S. adults that smoked in 2000.
Objective for the study : Whether the proportion of U.S. adults that smoke declined during the 5-year period between the samples.
i.e. 
Alternative hypothesis
is the statement containing population parameter that shows there is significant difference between the groups being tested.
⇒ 
Null hypothesis
is the statement containing population parameter that shows there is no significant difference between the groups being tested.
⇒ 
Hence, The hypotheses to test in this problem are


Hence, the correct answer is B. 

Answer: 6
Explanation:
A <em>constant</em> is a number or term that does not change. Usually it is the term that <em>does not </em>have a variable. In the equation, 6 cannot change. Therefore, the constant is 6
Answer:
d> 5.5
The graph in the attached figure
Step-by-step explanation:
we have

Solve the inequality for d
That means ---> isolate the variable d
Subtract 34 both sides

Divide by 12 both sides

The solution is the interval (5.5,∞)
All real numbers greater than 5.5
In a number line the solution is the shaded area at right of d=5.5 (open circle)
The value of d=5.5 is not included in the solution
