Step-by-step explanation:
The sum of 83 and a number would be as an expression, where is "said number".
Answer:
x=y/10-2.875
slope=10
y= (0,28.75)
Standard form; 40x-4y=-115
Step-by-step explanation:

The answer is -15=g. Hope this helps.
The answer is 30% because 6 divided by 20 is .3 and .3 x 100% = 30%
We have been given that a set of art exam scores are normally distributed with a mean of 81 points and a standard deviation of 10 points. Kamil got a score of 78 points on the exam. We are asked to find the proportion of exam scores that are lower than Kamil's score.
First of all, we will find z-score corresponding to 78.
, where,
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Now we will use normal distribution table to find the probability under a z-score of that is .
Upon rounding to 4 decimal places, we will get:
Therefore, of exam scores are lower than Kamil's score.
