Compare to slope intercept form of line y=mx+b
- Rate of change=m=-9
- Y intercept=b=55000
Initial value is 55000
Answer: 115.900
Step-by-step explanation: (I think)
V*t=S
V=3x10^8 m/s
S=7.5x10^6 m
t=S/V = 7.5x10^6 / 3x10^8 = 7500 000 / 300 000 000 = 0.025 s
<u>Alternate form:</u>
<u>u</u><u>=</u><u>76.48</u>
The standard deviation will be 6816.9645.
<h3>How to compute the standard deviation?</h3>
From the information given, the mean is 74000 and X is given as 60000.
P[(Z < (-60000 - 74000)/SD] = 0.02
Note that 0.02 will be -2.0537 under the normal distribution table.
-14000/SD = -2.0537
SD = -14000/-2.0537
SD = 6816.9645
