Since the inverse property of subtraction is addition, wouldn’t you add n on both sides so then the value of n=0?
Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean
of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be

As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
Answer:
The probability can be written as;
6/18
0.333
33.3%
Step-by-step explanation:
First we find the total number of marbles.
4 + 5 + 6 + 3 = 18
Now write the probability in the form of (favourable outcomes / possible outcomes), or 6/18.
Now let's divide.
6 ÷ 18 = 0.33333333... repeating decimal
0.333 × 100 = 33.33333.....%
We can also round this to 33%
Answer:
The median is 5, mode is 5, and range is 12
Step-by-step explanation:
Answer:
Equations::
4c + 8t = 58
2c + 3t = 23
----------------
Modify for elimination:
4c (4c*1) + 8t (8t*1)= 58
4c (2c*2) + 6t (3t*2)= 46
---------------------
Subtract and solve for "t":
2t (8t-6t) = 12
t = $6 (cost of one table)
-----
Solve for "c":
2c + 3t = 23
2c + 18 = 23
2c = 5
c = $2.50 (cost of one chair)
