Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.
1.5 miles/ .6 hours = 2.5 miles per hour
her walking rate is 2.5 miles per hour
d= r * t
4.5 miles = 2.5 * t
divide each side by 3.5
4.5 /2.5 = t
1.8 = t
t = 1.8 hours
11 am - 9 am = 2 hours
She will make it to work on time because 1.8 hours < 2 hours
The probability for a football player to suffer more than three roken bones will be the the sum of probabilities for 4 broken bones and five broken bones. Looking at the chart provided we can see that the probablity for 4 four broken bones is P(4)=0.10, and for 5 broken bones is P(5)=0.15. Thus the probaility,
P(x>3)=0.10+0.15=0.25.
