Answer:
1152
Step-by-step explanation:
Multiply 3200 * 0.045
144 * 8=1152
7.214 rounded to the nearest hundredth is 7.21<span />
The slope of any line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
The given points are (-14,-10) and (7,5), therefore:
y2 = 5
y1 = -10
x2 = 7
x1 = -14
Substitute with these values to get the value of the slope as follows:
slope = (5--10) / (7--14) = 5/7
Answer:
0.917915
Step-by-step explanation:
Exponential distribution is expressed as it follows
F (y,λ) = 1 – e ^(- λ(y)
)
Where λ is equal to 1/ population mean
So λ = 1/2.8 = 0.357
Let y be the length of time a costumer wait on hold
Now, let´s find the value for y = 7 minutes, which is the proportion of costumer that wait on hold
P (y<7) = 1 – e^(- .357*(7)
)
P (y<7) = 0.917915
Answer:
Step-by-step explanation:
1a:
3/1. 24/8 simplifies to 3/1.
1b:
18 points. The numerator and denominator of 3/1 can be multiplied by 18 to get 54/18.
2a:
2.45/1. 73.3/30 simplifies to 2.45/1.
2b: I don't really know, someone else might have to answer, but I hope what I did put helps!
