You have a 300 feet side length square and you need to calculate the length of the diagonal. When you split the square along one diagonal you get triangles, so you can apply Pythagoras' Theorem, with the hypotenuse as the needed diagonal.
a²+b²=c²
300²+300²=c²
2*300²=c²
√(2*300²)=c
√(2) * √(300²)=c
√(2) * 300=c
c~424.26 ft which is the solution/option c
Answer:
Option a) 1.6 .
Step-by-step explanation:
We are given that 142 subjects were treated with acupuncture. The numbers of migraine attacks for the treatment group had a mean of 1.8 and a standard deviation of 1.4 which means;
Sample Mean, = 1.8 , Sample standard deviation, s = 1.4 and Sample size = 142.
Now, 95% confidence interval estimate of the mean number of migraine attacks for all people treated with acupuncture is given by;
⇒
So, the lower bound = = 1.56 ≈ 1.6
Therefore, option A is correct.
Hi!
okay say you have the fractions 1/4 and 6/24, these two fractions are equivalent because you can multiply the numerator and the denominator by 6 to get 6/24 (1x6 = 6 and 4x6 = 24).
similarly you can reduce 6/24 to 1/4 by dividing the numerator and denominator by 6 (6/6 = 1 and 24/6 = 4).
i hope this helped!
The closest option to the actual answer is a.
1 5/18 is the actual answer.
If you make both the denominators the same, then you can actually add the fractions together.
To make both of the denominators the same, you need to multiply 5/6 by 9 and 4/9 by 6, which would result in 45/54 + 24/54= 69/54 = 23/18. If we convert it to a mixed fraction, it would result into 1 5/18.
