Answer: 9
Step-by-step explanation:
Based on the information given in the question, the expected number of people who pass will be calculated as:
= Probability of passing the driving test × Number of people tested
= 65% × 15
= 0.65 × 15
= 9.75
Therefore, expected number of people who pass is 9.

Answer:
There is a group anxiously waiting to start their triathlon. They are in the sand getting ready for the first leg of the race…the swim! They have roped off a rectangle of the beach that is 200 yards long and 10 yards wide. The athletes are packed in trying fighting for the front. If we assume that 10 athletes can occupy 25 square feet, how many triathletes are?
10 yds x 200 yds = 2000 sq yds.
2000 x 9 = 18000 sq ft
18000/25 = 720 sections that are 25 sq ft
720 sections x 10 people/section = 7200 triathletes

Answer :
x = - 12 for y = - 4
Step-by-step explanation:
Given as y = - 6 when x = - 14
write in equation form
I.e y = x + c
Put x and y values ,
So, c = y - x
c = - 6 + 14 = 8
Now when y = - 4 and c = 8 ,
So, from eq x = y - c
∴ x = - 4 - 8 = - 12 Answer
