Answer: True.
Step-by-step explanation: nice face.
Okay, so there are 4 weeks in a month. 30x4 is 120,and 3x4 is 12. Add the 2 together and you have 132$
Answer:
Which do you need help with?
1. -6 is 4 units from -2 in the negative direction.
2. A. and D
Step-by-step explanation:
When adding negative numbers the negative will be more, but if you are adding positive and negative numbers, whichever sign (+ or -) has the bigger number then that is the sign of the answer.
Additive inverses are when two numbers are added together to equal zero. Therefore if you have -3+3, it would be an additive inverse.
Hope this helps.
Answer:
(a) The sampling distribution of
= Population mean = 79
(b) P (
greater than 81.2 ) = 0.1357
(c) P (
less than or equals 74.4 ) = .0107
(d) P (77.6 less than
less than 83.2 ) = .7401
Step-by-step explanation:
Given -
Sample size ( n ) = 81
Population mean
= 79
Standard deviation
= 18
(a) Describe the sampling distribution of 
For large sample using central limit theorem
the sampling distribution of
= Population mean = 79
(b) What is Upper P (
greater than 81.2 ) =
= 
= 
= 
= 1 - .8643 =
= 0.1357
(c) What is Upper P (
less than or equals 74.4 ) =
= 
= 
= .0107
(d) What is Upper P (77.6 less than
less than 83.2 ) =
= 
= 
= 
= 0.9821 - .2420
= 0.7401
