Answer: The answer is - x-5/4
Step-by-step explanation:
Answer y=x,3x+3y+0
Step-by-step explanation:
The original price would have been 60 dollars because 25%of 60 is 20 so take twenty from sixty and you get forty
Using the normal distribution, it is found that the two readings that are cutoff values separating the rejected thermometers from the others are -1.96ºC and 1.96ºC.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
.
The z-score that cuts off the bottom and top 2.5% of the distribution is
, hence:


X = -1.96


X = 1.96
The two readings that are cutoff values separating the rejected thermometers from the others are -1.96ºC and 1.96ºC.

I'm gonna say that the answer if 12 (correct me if i'm wrong) so basically, following order of operations, you weed need to subtract something first, before that though, you need to find what number you can multiply 4 with to get 12, which the answer is 3. Knowing this, you need the subtraction problem to equal 3, so you add 3+2=5. x=5. so to put it in perspective, 5-2=3x4=12 hopefully i explained this well
