Answer:
q = 4.
Step-by-step explanation:
4(q + 1) = 20 Divide both sides by 4:
q + 1 = 5 Subtract 1 from both sides:
q = 4.
2x+3(3x-10)=14
2x+9x-30=14
11x=44
x=4
y=3(4)-10
y=2
Construct a 99% confidence interval for life
expectancy of a new GE light bulb:<span>
n = 64
Xbar = 750
s.d. = 20
Critical z value at 99% confidence = 2.576
margin of Error, E = 2.576*20/√64 = 6.44
<span>99% confidence interval for life expectancy of a
new GE light bulb = (Xbar - E; Xbar + E) = (743.56; 756.44)</span></span>
