1/12 because first u find a common denominator of 12 then you get 9/12 + (-8/12) and then since one is negative and one is positive you have to subtract and you get positive 1/12

I'm so confused. This question seems contradicting, and need an explanation.

Answer:

1/2 or 0.5 dollars per kg of apples

The first thing to do is to find out how much a kg of apples sells for, since the question is only asking for the selling amount of a single kg. Nothing else. Each trip gets 300 dollars and delivers fifty packs. So each Pack, or P = 300/50, or P = 6 dollars

And each pack contains 12 kg of apples, so if P = 6 dollars and P = 12 kg of apples, then 6 dollars = 12 kg of apples

then 1 kg apples = 6/12, or 1/2.

So a single Kg of apples cost 0.5 dollars

“Your salary is $25,000 and you will be receiving a 2.5% pay increase this year. What will your new salary be?”

Naddika [18.5K]

If your current salary is the 100%, and you get a 2.5% increase, that means the new salary would be 102.5% of 25,000. This percentage could also be written as 1.025, which you would multiply to 25,000 to get your new salary.

1.025 · 25,000 = 25,625

Therefore, your new salary would be $25,625

Answer:

7.64% probability that they spend less than $160 on back-to-college electronics

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 237, \sigma = 54$
