Angle 3= 80
Answer:
56/5
Step-by-step explanation:
2 4/10=24/10
8 4/5=44/5
24/10+44/5=24/10+88/10=112/10=56/5
Answer:
Mean = 30.68
Standard deviation = 6.095
Two standard deviations above the mean = 42.87
Step-by-step explanation:
Given the following data :
21; 21; 22; 23; 24; 24; 25; 25; 28; 29; 29; 31; 32; 33; 33; 34; 35; 36; 36; 36; 36; 38; 38; 38; 40
Mean = Σ(x) / n
n = 25
Σ (X) = 767
Mean (m) = 767 / 25
Mean (m) = 30.68
Standard deviation : sqrt[Σ(x - m) / n]
Using a calculator :
Standard deviation = 6.095 ( 2 decimal places)
2 standard deviations above the mean :
Mean + 2(standard deviation)
Mean + 2(6.095)
30.68 + 12.19
30.68 + 12.19
= 42.87
Answer:
THATS DUMB BRUH WORK TO MAKE $$$$$$
Step-by-step explanation:
You have to look to the tenths place. You then look at the number right behind it. In this case you look at the 5, and then the number behind it a 9. If the number behind is 5+ you bring the left number up. So .59 is rounded to the nearest .1 meter as .6!
