How many solutions can a single variable linear equation contain?

Burka [1]

Answer:

One solution

Step-by-step explanation:

As a generalization: an equation of degree n has n solutions. A quadratic equation has the second degree and thus two a solutions; a third degree equation has three, and so on. Thus, a first degree (linear) equation has one solution.

The circumferences of WNBA basketballs follow a normal distribution where mean = 29.0 ; and standard deviation = 0.1 inches.

slega [8]

Answer:

$P(X$

And we can find this probability using the normal standard distribution, excel or a calculator and we got:

$P(z$

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:

84%

Step-by-step explanation:

Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:

$X \sim N(29,0.1)$

Where $\mu=29$ and $\sigma=0.1$

We are interested on this probability

$P(X$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

$P(X$

And we can find this probability using the normal standard distribution, excel or a calculator and we got:

$P(z$

And if we convert this into percent we got 84.13% rounded to the nearest percent would be:

84%
