Answer:
y = - x + 9
Step-by-step explanation:
Because the line is perpendicular, the slope with be the opposite reciprocal. So, if the slope is 1 as in the equation y = x - 1, the opposite reciprocal is -1.
So the equation that is perpendicular will look like this so far:
y = -x + b (b represents our y-intercept that we have not found yet)
Now we will find the y-intercept. We can find it by substituting the coordinates (5,4) as x and y into the equation right above ^^.
So, 4 = -(5) +b or 4 = -5 + b
Add 5 to both sides to isolate b on the right side. b = 9
Therefore, the y-intercept is 9.
Now we have found everything we need for the equation, which is
y = - x + 9
Answer:
35.9
Step-by-step explanation:
The "work" is entering the numbers into a suitable probability calculator. A TI-84 calculator will tell you ...
invNorm(0.41,37.6,7.6) = 35.87065818
A score of about 35.9 separates the bottom 41% from the top 59%.
Between 75 and 98.
Step-by-step explanation:
Let's first have a look at the previous data available:
Friday, 27 dunk teachers out of 215 participants (12.5%)
Saturday: 54 dunk teachers out of 417 participants (12.9%)
Sunday: 39 dunk teachers out of 368 participants (10.6%)
So, based on the previous 3 days, she can expect between 10% and 13% will dunk a teacher.
If she has 750 contestants on Monday, the number of winners should then be in the range of 75 (10% of 750) and 98 (13% of 750).
28 + 53 = 81.
180 - 81 = 99.
Your missing length is 99 degrees.
( Just remember that all triangles add up to 180 degrees )

25 in of rain in 2 weeks.
there are 14 days in 2 weeks
25/14 = 1.785 in per day
1.785 x 31 = 55.335 in. of rain
55.335 in of rain is your answer
hope this helps
