Answer: 2x^2-7x-15
Step-by-step explanation:
reorder the terms (x*2+3)*(x-5)
multiply the parentheses
(2x+3)*(x-5)
collect like terms (2x^2-10x+3x-15)
product= 2x^2-7x-15
Answer:
1.33
Step-by-step explanation:
The z-score of a value is found by subtracting the mean from the value and then dividing by the standard deviation, this is the formula for the z-score.
z-score = (19-15)/3
z-score = 4/3
z-score = 1.33
The z-score for the monkey is about 1.33
