Answer:
13+(-19)=13-19=-6 is your answer
Answer:
The probability that no calls will occur during the next ten minutes is 0.0907.
Step-by-step explanation:
Poisson distribution:
Poisson distribution is a statistical distribution that helps to find out the number of events is likely occur in a specific time period.
Given that,
Calls occur at an average rate of 1.2 every 5 minutes.
The average rate of call is per minute.
Here,
, t=10 and x=0
=0.0907
The probability that no calls will occur during the next ten minutes is 0.0907.
Answer:
980.18 cm^3
Step-by-step explanation:
Volume of cylinder w/out spheres = pi r^2 h
= pi 8^2 *6
now subtract the volume of the TWO spheres
2 * 4/3 pi * 3^3
for result = 980.18 cm^3
Answer:
47.91 units²
Step-by-step explanation:
This can be solved using Heron's triangle (see attached)
in this case, your lengths are
a = 3+9=12
b=3+5=8
c=5+9=14
Hence,.
S = (1/2) x (a + b + c) = (1/2) (12+8+14) = 17
(s - a) = 17 -12 = 5
(s - b) = 9
(s - c) = 3
Area = √ [ s (s-a) (s-b) (s-c) ]
= √ [ 17 x 5 x 9 x 3 ] = √2295 = 47.9061 = 47.91 units² (rounded to nearest hundreth)
Yes because 18% is an abbysmal amount for a tip
