five times the larger of two consecutive odd integers is equal to one more than eight times the smaller. What is the larger inte

Margarita [4]

The formula to find two consecutive odd integers is x + (x+2)
5(x+2) = 1 + 8(x)
5x + 10= 1 + 8x
10= 1 + 3x
9=3x
x = 3
Answer : the larger integer is 5(3+2) which is 25

Answer: 95% confidence interval would be (0.344,0.456).

Step-by-step explanation:

Since we have given that

n = 295

x = 118

so, $\hat{p}=\dfrac{x}{n}=\dfrac{118}{295}=0.4$

At 95% confidence, z = 1.96

So, margin of error would be

$z\times \sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.4\times 0.6}{295}}\\\\=0.056$

so, 95% confidence interval would be

$\hat{p}\pm \text{margin of error}\\\\=0.4\pm 0.056\\\\=(0.4-0.056,0.4+0.056)\\\\ =(0.344,0.456)$

Hence, 95% confidence interval would be (0.344,0.456).
