Answer:
x < -6
Step-by-step explanation:
quick explanation: when you transfer (-9) to the other side it becomes +9.
Therefore, -15+9= -6
Calculate for the mean/ average of the given numbers:
μ = (1 + 2 + 3 + 4 + 5) / 5 = 3
Then, we calculate for the summation of the squares of differences of these numbers from the mean, S
S = (1 - 3)² + (2 - 3)² + (3 - 3)² + (4 - 3)² + (5 - 3)²
S = 10
Divide this summation by the number of items and take the square root of the result to get the standard deviation.
SD = sqrt (10 / 5) = sqrt 2
SD = 1.41
Thus, the standard deviation of the given is equal to 1.41.
B - (5 x 8) - 3
A is adding 3, not subtracting.
C is basically 5 squared.
D is 5 lots of 11.
If they made this trade, it would make sense that Mark would also have to give Ella $200. This is because the difference in value is that amount in the favor of Ella. You can see that by subtracting the two values from each other.
$1000 - $800 = $200
Answer:
74
Step-by-step explanation:
Using the Additive Inverse, it is the same as saying 57+17 = 74
