in the following equation A &amp; B are both integers. What is the value of a? What is the value of b?
MariettaO [177]
3ax-8a=b-18x
3ax+18x=b+8a
3x(a+6)=b+8a

3x=(b+8a)/(a+6)
x=(b+8a)/3(a+6)
3a*(b+8a)/3(a+6)=b-18*(b+8a)/3(a+6)
a(b+8a)/(a+6)=b-6(b+8a)/(a+6)
a(b+8a)=b(a+6)-6(b+8a)
ab+8a^2=ab+6b-6b-48a
ab+8a^2=ab-48a
8a^2=-48a
8a^2+48a=0
8a(a+6)=0 so a=0,-6
0=b-18x or -18x+48=b-18x
-b=-18x or 48=b
let b=18 if a =-6

A 90% confidence interval for the mean percentage of airline reservations being canceled on the day of the flight is (1.1%, 3.4%
Anton [14]
The point estimate would be 2.25%.

Confidence intervals are centered around a point estimate; that is, the point estimate is in the very middle of the confidence interval.  We can find the point estimate by averaging both ends of the confidence interval together:

(1.1+3.4)/2 = 2.25.

The value of the cumulative standardized normal distribution at z is 0.8770. what is the value of​ z?
Vinvika [58]
<span>The value of z is 0.8770. This answer was derived from information in the question, which states that the value of z is 0.8770. Granted, I don't understand what is meant by "cumulative standardized normal distribution." I only passed statistics because the professor felt sorry for me.</span>
