Ok so from my perspective
Answer:
Step-by-step explanation:
let x be the value of the denominator , then fraction is
adding 1 to numerator and denominator , gives
=
= ( cross- multiply )
2(x - 3) = x + 1
2x - 6 = x + 1 ( subtract x from both sides )
x - 6 = 1 ( add 6 to both sides )
x = 7
then original fraction
= =
Answer:
(0.095, 0.165)
Step-by-step explanation:
Confidence interval :
Phat ± margin of error
Margin of Error = 0.035
Phat = x / n
Phat = 11 / 85 = 0.1294117
Hence,
Phat ± 0.035
Lower boundary = 0.1294117 - 0.035 = 0.0944
Upper boundary = 0.1294117 + 0.035 = 0.1644
(0.0944, 0.1644)
The unit rate is $2.20 for each pencil because 11 divided by 5 is 2.2
