What does it mean if am equation is equivalent to 0=0? explain.

This means it has infinite solutions congrats. When solving algebraic equations you can find one solution, no solutions. When you have infinite solutions that means that equations has multiple things that can equal it.

Assume women’s heights are normally distributed with a mean of 63.6 inches and a standard deviation of 2.5 inches. a. If one wom

Zarrin [17]

Answer: a) 0.5636 b) 0.7881

Step-by-step explanation:

We assume that women’s heights are normally distributed .

Let x be the random variable that represents the shoe sizes.

Also, The population mean = $\mu=\text{63.6 inches}$ ; Standard deviation: $\sigma=\text{2.5 inches}$

a) Formula for z:-

$z=\dfrac{x-\mu}{\sigma}$

Put x= 64, we get

$z=\dfrac{64-63.6}{2.5}=0.16$

Now, the probability that the male shoe sizes are greater than 8 :-

$P(z$

Hence, the probability that her height is less than 64 inches = 0.5636

b. Sample size : n= 25

Then , the formula for z :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

Put x= 64, we get

$z=\dfrac{64-63.6}{\dfrac{2.5}{\sqrt{25}}}=0.8$

Then, the probability that they have a mean height less than 64 inches.:_

$P(z$

Hence, the probability that they have a mean height less than 64 inches. =0.7881
