Answer:
The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.
Step-by-step explanation:
Let's find an alternate hypothesis by using the formula:
mean=(sum of all data)/(number of data points) so:
sum of all data=9.0+7.3+6.0+8.8+6.8+8.4+6.6=52.9 and:
number of data points=7 so:
mean=52.9/7=7.56 pounds
The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.
From the points you get a slope of -1 using the slope in y=mx+b you get b=1 so y=-x+1
The answer is number 1. Because 12/10 =20/18 is a true statement. None of the others are true
If angle AEC is 90° and angle AEB bisects it and is 45° that right there proves that angle AEB bisects angle AEC
