Answer:

$53\frac{1}{2}\ in$

Step-by-step explanation:

we know that

The perimeter of a square is equal to

$P=4a$

where

a is the length side of the square

in this problem we have

$a=11\frac{3}{8}\ in$

convert to an improper fraction

$11\frac{3}{8}\ in=\frac{11*8+3}{8}=\frac{91}{8}\ in$

Find the perimeter of the square

$P=4\frac{91}{8}=45.5\ in$

Remember to adds two extra inches for each corner

The wood needed is

$45.5\ in+2*4\ in= 53.5\ in$

convert to mixed number

$53.5\ in=53\frac{1}{2}\ in$

Which is the graph of the following equation?

lesantik [10]

Given equation is

$\frac{(x-5)^2}{16} - \frac{(y-2)^2}{9}=1$

The given equation is in the form of

$\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2}=1$

a^2= 16 , so a=4

b^2 = 9 so b= 4

The value of 'a' is greater than the value of 'b'

So it is a Horizontal hyperbola

First two graphs are horizontal hyperbola

Here center is (h,k)

h= 5 and k =2 from the given equation

So center is (5,2)

Now we find vertices

Vertices are (h+a,k) and (h-a,k)

We know h=5, k=2 and a=4

So vertices are (9,2) and (1,2)

Second graph having same vertices and center

The correct graph is attached below

Answer:

Part A: yes

Part B: 50%

Step-by-step explanation:

There are two ways we can use a normal approximation for a sample: if the population it is from is normally distributed, or if the sample is sufficiently large (n > 30). In this case, we don't know if the population is normally distributed, but we do know the sample size is larger than 30, so we can use normal approximation.

The sample proportion is normally distributed, with a mean equal to the mean of the population. So there is a 50% chance that sample proportion is less than the population proportion.
