About 67 pairs. one shoe is left over. walking; 26 pairs running: about 41 pairs. sorry if im wrong
Use PEMDAS
1. 2(2^2)-2
=2(4)-2
=8-2
=6
2. 2((-2)^2)-(-2)
=2(4)+2
=8+2
=10
Z- score is a statistical tool that is used to determine the probability of finding a number or a value under a normal distribution plot. A normal distribution assumes that the mean is equal to zero and that the standard deviation is equal to 1. Using the z-score table, we can find the probability either on the right side or the left side. Using the table hence, we find the probability to the left of the value. The probability that is equivalent to the unknown z should be equal to 0.5 + (0.27/2) = 0.635. 0.5 comes from the assumption that the area under the curve on each side is 50% of the total. The equivalent z score is equal to z = 0.345.
Answer:
x=8
Step-by-step explanation:
then subtract the 6 from both sides of the equation
then subtract the 3x from both sides of the equation
then divide each side by -1
Answer: y=6
Step-by-step explanation:
Let's solve your equation step-by-step.
30y+40=220
Step 1: Subtract 40 from both sides.
30y+40−40=220−40
30y=180
Step 2: Divide both sides by 30.
30y/30= 180/30
y=6
