It will take the seal 6.5 hours to swim 52 miles.
Answer:e
Step-by-step explanation:
The equation for the submarine is given as y =-240x
Where y is the distance of the descent
x is the time in hours
and -240 is the rate of distance per unit time
To calculate how long it will take this submarine to reach the descent
x = y /-240
You can set up a proportion to determine the length of the enlarged photo
Answer:
The probability of 1 error in a period of 0ne - half minute is 0.1494
Step-by-step explanation:
Formula for poisson distribution:

If there is an average of 1 error in 10 seconds
In one-half minutes (i.e. 30 seconds), there will be an average of 30/10 errors = 3 errors


1! = 1

P(X = 1) = 3 * 0.0498
P(X = 1) = 0.01494
Answer:
b) $120 , $ 80
Step-by-step explanation:
Ratio = 3 :2
Total = 3 + 2 = 5
3/5 of 200 = 
= 3 * 40
= $ 120
2/5 of 200 = 
= 2 * 40
= $ 80
