Answer:
AB = 21
Step-by-step explanation:
So we have two triangles (AEB and ADC), and they're similar by AA
Now, you can find the ratio of similitude by checking AE/AD which is 14/26 = 7/13
AB/AC = 7/13
Take AB as x aight
x/x+18 = 7/13
x=21
Answer:
x=6 or x=2
Step-by-step explanation:
Well, ratios are basically fractions. There are 12 boys, so the ratio is 12/25. Since 25 - 12 is 13, there are thirteen girls, so the ratio of girls to student is 13/25.
Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
