6 / 9 = 2/3 ( since dividing top and bottom be 3 gives 2/3)
Also 4/6 = 2/3
Answer:
.2
Step-by-step explanation:
When you do 64/80 you get 0.8 which means that the percent decrease is .2
Converse (switch p and q)
If an angle is obtuse, then it measures 128°
This is false (a 127° angle is obtuse, but it does not measure 128°)
_____________________________________________________________
Inverse (negations of p and q)
If an angle does not measure 128°, then it is not obtuse
This is false (a 127° angle does not measure 128°, but it is obtuse)
_____________________________________________________________
Contrapositive (negations of p and q, then switch their places)
If an angle is not obtuse, it does not measure 128°
This is true (any 128° is obtuse; no exceptions)
Answer:
look at the angles. they all ad up to 180 degrees devide that by 9, and there you go!
Step-by-step explanation:
Answer: The maximal margin of error is 4.822.
Step-by-step explanation:
Since we have given that
Number of bags = 38
Sample mean = 78 ounces
Standard deviation = 14.5 ounces
At 96% confidence interval for the true population mean bags of nut weight.
So, z = 2.05
As we know that formula for "Margin of error":
Hence, the maximal margin of error is 4.822.
