Answer:
y= 2x -3
Step-by-step explanation:
The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, this is your current equation: y= 2x + b. Next, substitute your point into the equation to get the y-intercept. It should look like this: 9=2(6) + b. 6 times 2 equals 12. Now, this is what it should look like: 9=12 + b. Subtract 12 from both sides to get -3 = b. Go back to your original equation and plug in -3 to b. This is your final equation: y= 2x -3. Hope this helped!
<h2>
The least possible number among the missing scores is 83.</h2>
Step-by-step explanation:
If we arrange the test scores in non decreasing order then obviously will be at the third position since it is the median.
As it is not bimodal and the given mode is greater than the median the arrangement of test scores should be as given below.(assuming the unknown scores be and )
Now let us verify it with the mean;
⇒
⇒
Now for to be least; must be maximum possible value here.
Therefore is equal to
⇒
10-3(x-4)=5(12-2x)
10-3x+12=60-10x
7x+22=60
