Answer:
2.88
Step-by-step explanation:
Data provided in the question
= Population standard deviation = 7 miles per hour
Random sample = n = 32 vehicles
Sample mean = 
= 64 miles per hour
98% confidence level
Now based on the above information, the alpha is
= 1 - confidence level
= 1 - 0.98
= 0.02
For 
= 0.01
= 2.326
Now the margin of error is
= 2.88
hence, the margin of error is 2.88
8 bra cause that’s the answer I got for sure

Step-by-step explanation:
Consider the converses:
a) If two planes have no points in common, then they are parallel. (true)
b) If a point lies on the y-axis, then it has x-coordinate 0. (true)
c) If two angles have the same measure, then they are congruent. (true)
d) If a figure has four sides, then it is a square. (FALSE) (A figure with 4 sides may not even be a plane figure.)
Hello,
You have 7 balloons and in total, they cost 9.1. dollars. To find the unit price per balloon simply divide 9.1. by 7.
You'll get 1.3, OR 1.30.
To check your answer simply use inverse operations. Multiply 7 by 1.3 or 1.30 (it doesn't matter); you'll end up with the starting value 9.1.
Thus, the unit price per balloon is $1.30.
Faith xoxo
