Answer:
2.5
Step-by-step explanation:
you can use pythag theorem and divide c by two:
-3^2+4^2=c^2
9+16= 25
c=5
however, 5/2=2.5
Yes because if you find common denominators (in this case, "10") you would have to compare 8/10 to 5/10. 8>5 so 8/10 is longer than 1/2.
Answer:
43/100
Step-by-step explanation:
Step-by-step explanation:
1 kg = 1000 g
1.5 kg = 1500 g
1500 g : 350 g
= 150 : 35
= 30 : 7
Answer:
97.5% of American women have shoe sized less than 11.19
Step-by-step explanation:
Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19
The first thing we shall do here is to find the z-score
Mathematically, that will be calculated using the formula;
z = (x-mean)/SD
z = (11.19-8.15)/1.52
z = 2
We can see that the given value is 2 standard deviation away to the right of mean
So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule
So according to the empirical rule
The percentage will be
100-2.35-0.15
= 100-2.5 = 97.5%
