Answer:
Step-by-step explanation:
Since the ant travels at a constant speed, we can set up the following proportion:
, where 
is the distance the ant can travel in 7 minutes.
Solving for , we get:
.
Answer:
a. pi
Step-by-step explanation:
Let x be the number of adults (under 50 years old) after a 12-hour fast where X ~ N(85,25)
The problem is missing some parts but here are the answers:
(a) x is more than 60
z(60) = (60-85)/25 = -1
P(x > 60) = P(z > -1) = 0.158655
(b) x is less than 110
z(110) = (110-85)/25 = 1
P(x < 110) = P(z < 1) = 0.841345
The equation for the season pass would look like:
y=25x+350
Daliy pass:
y=67x+25x or y=92x
x is the amount of days and y is the total cost.
92x=25x+350 This equation will be how many days the cost will be equal
67x=350
x=5.223
The skier would have to go up 6 days to start saving from the season pass
7.55t + 100 ≥ 160 ( its greater than r equals to 160)
7.55t ≥ 60
t ≥ 7.95
Minimum number of hours = 8 ( to nearest hour).
