The slope of the line is 2, and it the equation for it is y=2x+1
Let's make a table of the days, and the number of mails sent each day:
Day nr of mails sent
Monday 9
Tuesday ?
Wednesday 13
Thursday 15
Friday 17
In the last 3 days, the number of mails increased each day by 2, so we could make the assumption that on Tuesday, there were 2 mails less sent than on Wednesday.
So, on Tuesday, we assume that 13-2=11 mails were sent.
We check this assumption with the number of mails sent on Monday, and it works again. So, our assumption is correct.
Answer: 11
Answer:
C.) 217
Step-by-step explanation:
If the top 4% of athletes are allowed to be part of the team, then the bottom
will not qualify.
We look for a z-score below which
of the population lie.
Reading from the z-table as shown in the attachment, this z-value corresponds to
.
We now use the z-score formula to find the required minimum qualifying score.

where 
We substitute and solve for x.





The correct choice is C
Assuming the given scenario is a right angle triangle; (it helps to draw a diagram of the person and what they are seeing to better understand this question).
tanФ=opp/adj
tan(24)=(height of building)/280
280×tan(24)=height of building
124.66 m = height of building.
Hope I helped :)
