Step-by-step explanation:
Answer:
ST is equal to TS because they are both the same line, just vertically flipped over the y-axis. Triangle RST is equivalent to Triangle UTS because they have the same area. (Rectangle cut into two equal-sized triangles)
Hello there.
<span>How many centimeters are in a meter?
100</span>
Out of 90 reservation made, 77 diners are expected to show up. And the standard deviation of this binomial distribution is 3.39
We have been given that
Percentage of people who make reservation and didn’t show up = 15% = 0.15
Number of reservation made = 90
Now we have to calculate number of people expected to show up that is we have to calculate mean. As this a binomial distribution in which we have been given
n = 90 and q = 0.15
Thus, µ = np = 90*(1-0.15) = 90*0.85
µ = 76.5 ≈ 77
Thus it is expected to have 77 diners to show up.
Now standard deviation is given as:
σ = √npq
σ = √90*0.15*0.85
σ = 3.39
Hence the standard deviation is 3.39
