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%
Answer: You would want to expand the polynomial using the FOIL method.

Step-by-step explanation:
The contracted phone plan will have the same steepness and a higher y-intercept.
<span>4x−3y=12
7x−3y=3 Important: you have two -3y terms. Mult one eqn by -1 to
obtain +3y, and then add the 2 equations together:
4x - 3y = 12
-7x+3y = -3
----------------
-3x = 9, so x = -3. Subst. -3 for x in the first original equation to find y:
4(-3) - 3y = 12, or -3y = 24. Then y = -8.
Solution is (-3, -8).
It's important that you check this answer by subst. (-3, -8) back into either one of the original equations.
