The correct answer is B) -0.3
Z-scores are found using the formula
z = (X-μ)/σ
For this problem, we have
z = (24-24.5)/1.7 = -0.5/1.7 = -0.3
Answer:
64
Step-by-step explanation:
4^3=64
4*4=16
16*4=64
Answer:
Identify the known ratio and the unknown ratio.
Set up the proportion.
Cross-multiply and solve.
Check the answer by plugging the result into the unknown ratio.
I would use elimination. I would multiply 4x+3y=2 by 3 so the it becomes 12x+9y=6, and I would multiply the bottom equation by 4 so that it becomes 12x+8y=4. Because I am using elimination I have to get rid of one variable, I chose to get rid of X hence that the coefficient of X in each equation is now 12. i simply subtract both equations and get y by itself. y=2. I plug in Y to find x in either of the original equations, where I get x=-1. To check my work substitute the values of x and y in the other equation. 4(-1)+3(2)=2 -------> 2=2
