Answer:
a) 0.1535
b) 0.4866
c) 0.8111
Step-by-step explanation:
The probability that the next call come within the next t minutes is:
According to this model,
a) the probability that a call in comes within 1/2 minutes is
=0.1535
b) the probability that a call in comes within 2 minutes is
=0.4866
c) the probability that a call in comes within 5 minutes is
=0.8111
23 and 9 are the two numbers
Explanation:
x = one number
y = other number
x + y = 32 {sum of two numbers is 32
x - y = 14 {difference is 14}
-----------
2x = 46 {added the two equations together}
x = 23 {divided both sides by 2}
x + y = 32 {top equation}
23 + y = 32 {substituted 23, in for x, into top equation}
y = 9 {subtracted 23 from both sides}
23 and 9 are the two numbers
Answer:
Slope -
Y intercept 1
so option 2 or B
Step-by-step explanation:
Slope is rise over run so 1 over -2
so -1/2
and y intercept is where the line crosses the y axis and it crosses on this graph at positive 1.
20 multiplied (times) 4 is equal to 80 c:
Answer:
Tina
Step-by-step explanation:
bc if you sub in 4 for x the equations on both sides are 0
check:
-4 + 4 = 0 -3 x 4 = -12
0 x 3 = 0 12 + -12 = 0
0 = 0
