Tiled floor with 225 square tiles means the area of the square room is 225.

Formula needed: A = (side)^2 or in short

A = s^2.

We need to find s.

225 = r^2

sqrt{225} = sqrt{r^2}

15 = r

There are 15 tiles are along an edge of the room.

Pachacha [2.7K]

Answer:

a) In the explanation.

b) P=0.09714

c) P=0.0866

d) p=0.208

Step-by-step explanation:

a) The sampling distribution will have this properties:

1 - The sampling distribution of a proportion is equal to the binomial distribution.

2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

\mu=\pi=0.328

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

\sigma_s=\sqrt{\pi(1-\pi)/n}=\sqrt{0.328*(1-0.328)/25}=0.094

B) The fraction with sample proportion of 0.45 or higher is

z=(p-\pi)/\sigma=(0.45-0.328)/0.094=1.298\\\\P(p\geq0.45)=P(z\geq 1.298)=0.09714

C) The fraction with sample proportion of 0.20 or lower is

z=(p-\pi)/\sigma=(0.2-0.328)/0.094=-1.362\\\\P(p\leq0.2)=P(z\geq -1.362)=0.0866

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.

Then we have

z=(p-\pi)/\sigma\\\\p=\pi+z\sigma=0.328+(-1.28)*0.094=0.328-0.120=0.208

Answer:

it's 1/7^2

Step-by-step explanation:

When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.

When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2
