I'm not sure how to answer this and I don't even know what type of math it is [closed]
$begingroup$
I'm studying for a finals about probability distribution with Z-table and I got to this part in the example of my lecturer and I have no idea how she arrived to this answer, I've been staring at it and scratching my head for a good 30 minutes and still don't know how she got it.
I assume this is probably some basic stuff from high school that I just forgot xD, so please help this stupid college student out haha
-2.33 = h-172/8
h = 153.4
How did she get 153.4?

Knowledge that is commonly missing in college is fractions and solving equations with a variable. Unfortunately they are assumed to be known, so some dedicated training with them may be required.
I'll step you through the process for this one.
$$begin{aligned}
-2.33 &= frac{h-172}{8} \
-2.33 times 8 &= frac{h-172}{8} times 8 & text{Cancel division by 8}\
-2.33 times 8 &= h-172\
-2.33 times 8 + 172 &= h-172 + 172 & text{Cancel subtraction of 172}\
-2.33 times 8 + 172 &= h &\
h &=-2.33 times 8 + 172 = 153.36 approx 153.4\
end{aligned}
$$
