Answer:
A)26
Step-by-step explanation:
12 nin dogal sayi bolenleri 1,2,3,4,6 ve 12 dir yani ucgen 6 dir
20 nin en kucuk kati 20 yani kendisidir(20 kendisinin 1 katidir)
2+2=4 and 4+4=8 and 8+8=16
Area = 1/2(Base * Height)
Area = 1/2(6*20) = 60m^2
the area of the triangle is 60m^2
Using the Empirical Rule, it is found that standard deviation of the sample proportions is of 0.058.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
0.684 and 0.916 is within 2 standard deviations of the mean(below and above), hence there are 4 standard deviations between these measures, so:
4s = (0.916 - 0.684)
s = (0.916 - 0.684)/4
s = 0.058.
