Answer:

Perimeter: 17 inches

Area: 8 square inches

Step-by-step explanation:

The ratio of perimeters is the same as the similarity ratio.

JKLM perimeter / ABCD perimeter = P/68 = 1/4

Multiplying by 68, we get ...

P = 68/4 = 17 . . . . inches

The ratio of areas is the square of the similarity ratio.

JKLM area / ABCD area = A/128 = (1/4)^2

Multiplying by 128, we get ...

A = 128/16 = 8 . . . . square inches

Perimeter = 17 inches

Area = 8 square inches

According to a study conducted by the Gallup Organization, the the proportion of Americans who are afraid to fly is 0.10. A rand

Answer: 0.1457

Step-by-step explanation:

Let p be the population proportion.

Given: The proportion of Americans who are afraid to fly is 0.10.

i.e. p= 0.10

Sample size : n= 1100

Sample proportion of Americans who are afraid to fly = $\hat{p}=\dfrac{121}{1100}=0.11$

We assume that the population is normally distributed

Now, the probability that the sample proportion is more than 0.11:

$P(\hat{p}>0.11)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.11-0.10}{\sqrt{\dfrac{0.10(0.90)}{1100}}})\\\\=P(z>\dfrac{0.01}{0.0090453})\ \ \ [\because z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}} ]\\\\=P(z>1.1055)\\\\=1-P(z\leq1.055)\\\\=1-0.8543=0.1457\ \ \ [\text{using z-table}]$

Hence, the probability that the sample proportion is more than 0.11 = 0.1457
