Given M = 120, σ = 5.6
P (117.4 <x<120)
P (" 117.4-120 5.6 < X-M 120-120 5.6
P(-0.46 < 220)
= 0.5= P(-0.46 <2)
= 0.5 0.3212
0.1788
The standard deviation is 0.1788
Standards contain technical specifications or other precise criteria intended to be used consistently as rules, guidelines, or definitions. They make life easier and help increase the reliability and effectiveness of many of the products and services we use. . Most state regulations require drivers to have liability insurance and stipulate the exact amount of coverage required.

∠C
<u>Step-by-step explanation:</u>
It is 22.81 that’s the percent of 57
There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171
