Answer:
The answer would be 22/12 or 1 and 11/12
Step-by-step explanation:
1/2+2/3+3/4
First get common denominators so you have a denominator of 12 so 6/12+8/12+9/12
Add those together and you get 23/12 but you have to subtract one because that's what the problem says so you get 22/12
Answer:
The first one
Step-by-step explanation:
An easy way is SOH CAH TOA
SOH is that you use sine if you there is the opposite (in this case the question mark) and hypotenuse (the diagonal line)
CAH is that you use cosine for the adjacent side (1100) and the hypotenuse.
TOA is using tangent for the opposite and adjacent side.
To fine the question mark, you would use tangent. And plug in the given (1100 for the adjacent). So tan45 = x/1100.

/50 = /25•2
/25 • /2 further written as
5 • /2 simplified form
so A
The answer is 79 im sure of it
Answer:
Standard deviation 46.3
Step-by-step explanation:
A 28% of the distribution is equivalent to a z score of -0.5828, you can use a z table to find that.
Z score is calculated as follows:
x is the number being evaluated
μ is the mean
σ is the standard deviation
And it is used to calculate how many standard deviations you are from the mean of the sample.
Replacing with the known information you can calculate the standard deviation:
