Answer: 3x - 9
Step-by-step-explanation: To solve the expression (8x – 2) – (5х – 7) we will be using properties of operations. First, use the commutative and associative properties to move the values next to each other to combine like terms.
(8x – 2) – (5х – 7)
(8x-5x)+(-2-7)
3x-9
So, the subtracted answer is 3x - 9
Hi there!
<u>Set A has a LARGER standard deviation. </u>
A set's standard deviation is equivalent to:

σ = standard deviation
x = value
μ = mean
n = # of observations
Basically, standard deviation is calculated using how far apart EACH value is from the set's mean. If more values are FARTHER away from the mean, the standard deviation increases and vice-versa.
Set A has a GREATER RANGE and its values are farther from 13 on both sides compared to Set B which has a SMALLER RANGE and its values are closer to 13.
Therefore, Set A will have a larger standard deviation.
Answer:
Step-by-step explanation:
P = 2,828 + 125t
8,453 = 2,828 + 125t
5625 = 125t
t = 45
