Answer:
M=(4,112)=(4,5.5) A
Step-by-step explanation:
The midpoint for two points P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2).
We have that px=3, py=2, qx=5, qy=9.
Thus, M=(3+52,2+92)=(4,112).
Answer:
Graph the second equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis. At the point of intersection of the two equations x and y have the same values.
Answer:
x = 1.02.
Step-by-step explanation:
The x is a factor worked out from the annual interest written as a decimal fraction.
So we have 2% = 2/100 = 0.02.
The amount at the end of the first year is $100 + 0.02*100
= $100* 1.02, and in the second year it will be $100* 1.02^t where t = 2 and so on.
So we see that x in the given expression is 1.02.
Answer: A is 70 B is 45 and C is 50
Step-by-step explanation:
Answer: The treatments in the study are strength training, flexibility training, aerobics, and jogging.
Step-by-step explanation:
A correct description of a feature of the study is that the treatments in the study are strength training, flexibility training, aerobics, and jogging.
It should be noted that the study has no replication. Also, the experimental units are the 40 members that participated.
Therefore, the correct option is D.
