Answer:
1.308
Step-by-step explanation:
–10.9p + 3.9 = –9.18
=> -10.9p=-9.18-3.9
=> -10p=-13.08
=> p=-13.08/-10
cut minus sign from both sides
=> p= 13.08/10
=> p= 1.308

Answer:
a. $185
b. 64 miles
c. 26 miles
d. x > 0
Step-by-step explanation:
a. Find C(x) when x = 40.
C(x) = 2.5 x + 85
C(40) = 2.5 (40) + 85
C(40) = 185
b. Find x when C(x) = 245.
C(x) = 2.5 x + 85
245 = 2.5 x + 85
160 = 2.5 x
x = 64
c. Find x when C(x) = 150.
C(x) = 2.5 x + 85
150 = 2.5 x + 85
65 = 2.5 x
x = 26
d. The domain of C is all the possible values of x. Since x is a distance, it doesn't make sense for it to be negative, so x > 0.
Answer:

Step-by-step explanation:
Number of students participating in the competition = 13.
Total number of students in the school = 15.
Thus ,
the number of students who did not make to this competition =
Total number of students - number of students participated
= 15-13 = 2.
Now ,
probability of the student who do not makes it to the competition
= fraction of students who did not make to this competition from the total number of students .
=
.
