Answer:
The equation that represents the relationship between 'y' the total points, and 'x' the number of movies is option A;
A y = 3·x
Step-by-step explanation:
The information required in the question is an equation that represents the the relationship between the number of movie attended and the total number of points Marcy has given that she earns a fixed amount of points for attending each movie
The number of points she will earn for attending each movie = 3 points
The total number of points she will earn 'y' when she attends 'x' number of movies is given as follows;
y = 3 + 3 + 3 + ... + 3, 'x' number of times, and we can write
Therefore the equation that represents the relationship between 'y' the total points, and 'x' the number of movies is y = 3·x.
Answer:

Step-by-step explanation:
Answer:
y= -2/5x
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have been told that the ratios are inversely proportional in our given problem. We are asked to find the missing value.
We know that two inversely proportional quantities are in form , where, y is inversely proportional to x and k is the constant of proportionality.
Let us find constant of proportionality using and in above equation.
Now, we will use and in our equation to find as:
Therefore, the value of is 9.
The test statistic for difference between two means is given by:
Thus, the appropriate test statistic is given by:
At 10% level of significance, the rejection region is given by
where:
for 10% level of significance is 1.65
Since z = 1.66 >
, we reject the null hypothesis, which means that <span>the traffic control strategy does not reduce carbon monoxide concentrations by at least 2 ppm.</span>
