Answer:
What is the probability the mean of his sample will be between $70.00 and $80.00? = 64/64 =1
s1) = 99% =z score = 127/128
s2)64/64 = 1
s3)95% of 64 = 123/128
s4) p) step 3 = 95% of 64 = 60.08 /64 = 60/64 = 93.75%
s5) P)of 2+4 = 283/292 = 96.92%
3 inches i agree too 2020
Answer:
Perimeter =28 units.
Area = 45 unit^2.
Step-by-step explanation:
The length of first side (joining first 2 points) = 5 - (-4) = 9 (as y coordinates are both -5)
The line joining the 2nd and third points = 0 - (-5) = 5
The line joining the 3rd and 4th points = 5 - (-4) = 9.
The line joining the first and 4th points = 0 - (-5) = 5
So the perimeter = 2(5) + 2(9)
= 28 units.
Area = 5*9 = 45 unit^2.
If the number of positive signs is even and the number of negative signs is odd then it is negative and vice versa. If the number of positive signs is even and the number of negative signs is even then the answer is odd. If the number of positive and negative signs are odd then the answer is always negative.
