70000000000
8000000000 that is the answer I wonder why ieven downloaded this app self you guys fraust me every time
Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.
Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8
Answer:
(D)109
Step-by-step explanation:
Mean = 450 seconds
Standard deviation = 50
First, we determine the probability that the expected response time is between 400 seconds and 500 seconds, P(400<x<500)
Using the Z-Score,
![P(\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=P%28%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%20%3Cx%20%3C%20%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%29%5C%5C%3DP%28%5Cfrac%7B400-450%7D%7B50%7D%20%3Cx%20%3C%20%5Cfrac%7B500-450%7D%7B50%7D%29%5C%5C%3DP%28-1%3Cx%3C1%29)
From the Z-Score table
P(-1<x<1) = 0.68269
The probability that the expected response time is between 400 seconds and 500 seconds is 0.68269.
Since there are 160 Emergencies
Number whose expected time is between 400 seconds and 500 seconds
![=160 X 0.68269 \approx 109](https://tex.z-dn.net/?f=%3D160%20X%200.68269%20%5Capprox%20109)
Answer:
(-1,0)(0,1)(3,4)
Step-by-step explanation:
Remember that the slope intercept formula is:
y = mx + b
m is the slope (
)
b is the y-intercept
In this case the slope is...
![\frac{-1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B3%7D)
^^^This has a negative slope because the line is decreasing from left to right
The y-intercept is...
(0, -2)
so...
y =
x - 2
Hope this helped!
